Programmatic creation via an HTTP API. A command-line tool that scripts that API for shell workflows. Webhook delivery so an alias can pipe into a workflow runner rather than a human inbox. Per-project custom domains so a single side project&#8217;s mail doesn&#8217;t pollute the same namespace as your day-job accounts. The underlying mechanism is described in our <a href=\"https:\/\/emailalias.io\/blog\/what-is-an-email-alias\/\">what is an email alias explainer<\/a>, and the day-to-day mechanics in <a href=\"https:\/\/emailalias.io\/blog\/how-email-aliases-work\/\">how email aliases work under the hood<\/a>; this guide is about the developer-specific surface area on top of them. The underlying SMTP forwarding mechanic is the same one specified in <a href=\"https:\/\/datatracker.ietf.org\/doc\/html\/rfc5321\" rel=\"noopener\" target=\"_blank\">RFC 5321<\/a> and summarised on <a href=\"https:\/\/en.wikipedia.org\/wiki\/Email_forwarding\" rel=\"noopener\" target=\"_blank\">Wikipedia&#8217;s email forwarding article<\/a>.<\/p>\n\n\n\n<p>The reason the developer use case deserves its own evaluation: a developer&#8217;s account count is typically one to two orders of magnitude higher than a consumer&#8217;s. Every npm package you publish needs a maintainer email. Every GitHub Actions workflow that posts to a Slack webhook needs an identity. Every staging environment that runs a transactional-email integration needs an address that can receive the outgoing mail without burning your personal inbox. An email alias for developers exists to provide all of these in a way that a script can create, scope, and tear down without ever opening a browser.<\/p>\n\n\n\n<p>None of this is a different product from a consumer alias service \u2014 it&#8217;s the same product evaluated against a different feature axis. The five providers below all offer a baseline consumer alias experience; the comparison here is which of them have actually invested in the programmatic interface that makes a developer&#8217;s life materially easier.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-developers-need-a-dedicated-email-alias-setup\">Why developers need a dedicated email alias setup<\/h2>\n\n\n\n<p>The case for an email alias for developers comes down to four pressures that the rest of the population doesn&#8217;t feel at the same intensity:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Account density.<\/strong> A working developer signs up for ten to thirty new services a quarter \u2014 SaaS trials, OSS package registries, monitoring tools, CI providers, cloud accounts, vendor portals. Each is a future leak risk if it ever gets breached \u2014 a quick check against <a href=\"https:\/\/haveibeenpwned.com\/\" rel=\"noopener\" target=\"_blank\">Have I Been Pwned<\/a> will surface how many corpora your personal Gmail already appears in. Sharing a single Gmail across all of them turns one breach into a credential-stuffing attempt against every other.<\/li>\n\n\n\n<li><strong>Identity bleed across personal and work contexts.<\/strong> Side projects, freelance clients, open-source maintainership, and a day job all want different identity boundaries. An email alias for developers scoped per-project makes those boundaries actual rather than aspirational.<\/li>\n\n\n\n<li><strong>Sender exposure on commits and packages.<\/strong> Git commits, npm package metadata, RubyGems author fields, and CRAN maintainer listings publish your email permanently. A burner alias for these prevents a public commit log from feeding a spam-scraping pipeline for the next decade.<\/li>\n\n\n\n<li><strong>Programmatic lifecycle.<\/strong> Aliases created and revoked by hand are a chore that does not survive contact with the actual rate of account churn. Scripted creation and revocation are the only way the discipline holds across a real developer&#8217;s workflow.<\/li>\n<\/ul>\n\n\n\n<p>The same underlying logic applies to anyone with high account volume \u2014 but the leverage of fixing it programmatically is highest for developers, because the tooling to drive an API or a CLI is already part of the daily workflow. The right email alias for developers is the one that meets you in that workflow rather than pulling you into a separate web dashboard for every new alias.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-we-evaluated-the-best-email-alias-for-developers\">How we evaluated the best email alias for developers<\/h2>\n\n\n\n<p>The criteria for picking the best email alias for developers are not the same as for a consumer pick \u2014 the obvious consumer factors (price, free-tier alias count, mobile app polish) still matter but rank below the programmatic ones. The dimensions we weighted in this comparison:<\/p>\n\n\n\n<ol>\n  <li><strong>Public, documented HTTP API.<\/strong> Not a &#8220;contact sales for API access&#8221; \u2014 an actual endpoint reference a developer can read in five minutes and call from <code>curl<\/code>.<\/li>\n  <li><strong>CLI availability.<\/strong> Either first-party or actively maintained community tooling that wraps the API. Reduces the friction of &#8220;create me an alias for this thing I&#8217;m signing up for right now&#8221; to a single shell command.<\/li>\n  <li><strong>Custom-domain support.<\/strong> Without this, every alias you create is tied to the provider&#8217;s domain forever. With it, your aliases survive any single provider&#8217;s shutdown \u2014 the property covered in detail in our <a href=\"https:\/\/emailalias.io\/blog\/what-happens-if-my-alias-provider-shuts-down\/\">guide to provider shutdown survival<\/a>.<\/li>\n  <li><strong>Self-hostability or open source.<\/strong> Not a hard requirement, but a tiebreaker for developers who want a fallback path if the hosted service shifts pricing or shuts down. We covered the portability angle separately in our <a href=\"https:\/\/emailalias.io\/blog\/email-alias-portability-guide\/\">email alias portability guide<\/a>.<\/li>\n  <li><strong>Webhook \/ forwarding flexibility.<\/strong> Forwarding to a workflow runner, a Slack-bot URL, or a downstream API matters more for developers than for consumers, who mostly want mail in a single inbox.<\/li>\n  <li><strong>Per-alias controls and logs.<\/strong> Disable, rotate, see delivery logs, track which sender hit which alias \u2014 the audit-trail surface area a developer uses to debug forwarding rules and chase leaks.<\/li>\n<\/ol>\n\n\n\n<p>Price still appears in the comparison table for completeness, but it intentionally doesn&#8217;t drive the rankings. Every provider in the list is cheap enough that for a working developer it falls inside the &#8220;round-down to free&#8221; budget category. The ranking is purely about which tool gets you to a working programmatic setup with the fewest workarounds. For a broader head-to-head that includes consumer-oriented picks, our <a href=\"https:\/\/emailalias.io\/blog\/email-alias-services-2026\/\">2026 email alias services comparison<\/a> covers the wider field.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"the-best-email-alias-for-developers-compared\">The best email alias for developers compared<\/h2>\n\n\n\n<p>The table below is the at-a-glance summary across the six dimensions above.

Order them by how often you&#8217;d actually use each in a typical week:<\/p>\n\n\n\n<ol>\n  <li><strong>Public API with auth tokens.<\/strong> Non-negotiable for any email alias for developers worth picking. Without it, you&#8217;ll be doing dashboard clicks every time you sign up for a new service.<\/li>\n  <li><strong>CLI or shell-friendly wrapper.<\/strong> Reduces alias creation to a single command with a label argument. A 10-line bash function over <code>curl<\/code> is acceptable if the API is clean; a real CLI is better.<\/li>\n  <li><strong>Custom-domain support.<\/strong> The single most important property for portability \u2014 without it, every alias you create dies if the provider goes down. Discussed in detail in our <a href=\"https:\/\/emailalias.io\/blog\/what-happens-if-my-alias-provider-shuts-down\/\">provider shutdown survival guide<\/a>.<\/li>\n  <li><strong>Per-alias logs.<\/strong> Critical for debugging forwarding rules and chasing leak attribution. Without per-alias logs, you can&#8217;t tell which sender hit which alias when something goes wrong.<\/li>\n  <li><strong>Send-from-alias.<\/strong> For developer use cases that involve replying \u2014 vendor support, OSS maintainer mail, freelance client correspondence \u2014 outbound from the alias matters as much as inbound. Without it, replying reveals your real address and the alias is half-cooked.<\/li>\n<\/ol>\n\n\n\n<p>One feature notable for being absent from this list: a dedicated mobile app. For the developer profile, a mobile app is irrelevant \u2014 the operations that matter happen at a terminal, not on a phone. Providers that lead with mobile UX (most of the consumer-facing ones) often under-invest in the API surface, and the comparison above weights accordingly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-set-up-an-email-alias-for-developers\">How to set up an email alias for developers<\/h2>\n\n\n\n<p>The end-to-end setup for an email alias for developers is intentionally a one-evening project. The sequence below works for any of the providers above that expose an API; the exact endpoint shapes differ, but the operations are the same.<\/p>\n\n\n\n<p>Step zero is picking which provider, which the comparison above is for. With that decided, the next steps run roughly in parallel \u2014 register an account, generate an API token, and put it somewhere your shell can find it. Most developers store the token in a password manager and load it into the shell on demand rather than committing it anywhere persistent.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-style-default\">\n  <img data-recalc-dims=\"1\" src=\"https:\/\/i0.wp.com\/emailalias.io\/blog\/wp-content\/uploads\/2026\/06\/diagram-email-alias-for-developers-setup.jpg?resize=1080%2C567&#038;ssl=1\"\n       alt=\"How to set up an email alias for developers: API token, CLI wrapper, and a custom domain feeding aliases into per-project inboxes\"\n       width=\"1080\" height=\"567\"\n       loading=\"lazy\" decoding=\"async\" \/>\n  <figcaption>The end-to-end setup for an email alias for developers: API token in the shell, CLI wrapper that scripts the API, and a custom domain so aliases survive any single provider&#8217;s shutdown.<\/figcaption>\n<\/figure>\n\n\n\n<ol>\n  <li><strong>Create the account and verify the email.<\/strong> Use a recovery address you actually own \u2014 not a previously-aliased one. The recovery address is the only thing standing between you and a lockout if you lose the API token.<\/li>\n  <li><strong>Generate an API token.<\/strong> Most providers scope tokens per-purpose. Create one specifically for CLI use; revoke it independently of the dashboard session if it leaks.<\/li>\n  <li><strong>Add a custom domain.<\/strong> Point the MX record at the provider per their docs. This is the step that gives you portability \u2014 your aliases live on a domain you own, not on the provider&#8217;s namespace.<\/li>\n  <li><strong>Drop a CLI wrapper in your shell config.<\/strong> A 10-line bash function over <code>curl<\/code> works for the simplest case. For more, install the provider&#8217;s first-party CLI if one exists.<\/li>\n  <li><strong>Test inbound and outbound.<\/strong> Create one alias, send a message to it from a throwaway account, confirm forwarding works. Then reply from the alias if your provider supports outbound \u2014 confirm the From address is the alias, not your real inbox.<\/li>\n  <li><strong>Wire it into your password manager.<\/strong> The faster the create-alias action is at signup time, the more aliases you&#8217;ll actually use. 1Password, Bitwarden, and the SimpleLogin browser extension all have alias-generation integrations worth turning on.<\/li>\n<\/ol>\n\n\n\n<p>Once the pipeline is in place, the per-signup overhead drops to one command \u2014 typically something like <code>alias create chase-checking<\/code> \u2014 and the output is an address you paste into the signup form. The setup time amortises across every account you&#8217;ll create for the rest of your career as a developer. The discipline also lines up with broader account-isolation guidance from sources like the <a href=\"https:\/\/www.eff.org\/issues\/privacy\" rel=\"noopener\" target=\"_blank\">EFF&#8217;s privacy resources<\/a> \u2014 separate identities per service is one of the few defences that scales with how many accounts a developer accumulates over a decade. If you&#8217;ve previously been told an alias is the same thing as a throwaway address, our <a href=\"https:\/\/emailalias.io\/not-disposable-email\/\">not a disposable email primer<\/a> spells out the difference.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"common-developer-use-cases\">Common developer use cases<\/h2>\n\n\n\n<p>Once an email alias for developers is wired up, the use cases tend to expand beyond the initial &#8220;signup for a SaaS trial&#8221; pattern. The five recurring ones across most working developers:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>OSS maintainer identity on commits and package metadata.<\/strong> Burn a per-project alias for the author field on npm packages, Cargo crates, RubyGems, etc. The address ends up in package indexes permanently \u2014 give it an alias rather than your personal Gmail, and you can revoke it years later without affecting anything that still needs to reach you. GitHub&#8217;s <a href=\"https:\/\/docs.github.com\/en\/account-and-profile\/setting-up-and-managing-your-personal-account-on-github\/managing-email-preferences\/setting-your-commit-email-address\" rel=\"noopener\" target=\"_blank\">commit-email documentation<\/a> covers the related no-reply option for the GitHub identity itself.<\/li>\n\n\n\n<li><strong>SaaS trial signups.<\/strong> One alias per trial. If the trial converts to a paid relationship you keep, the alias lives on. If it doesn&#8217;t, you disable the alias and the residual marketing mail stops cold.<\/li>\n\n\n\n<li><strong>CI\/CD integrations.<\/strong> An alias per pipeline that needs to receive notifications \u2014 failed build alerts, deployment confirmations, vendor webhooks. The alias maps to a single Slack channel or workflow runner without exposing your real inbox.<\/li>\n\n\n\n<li><strong>Per-environment transactional email testing.<\/strong> Staging and prod each get their own alias; mail intended for testing lands in a clearly-labeled inbox slice. No more &#8220;I forgot to swap the email recipient before pushing to prod&#8221; incidents.<\/li>\n\n\n\n<li><strong>Freelance and consulting client correspondence.<\/strong> One alias per client. If the engagement ends, the alias gets revoked and so does the long tail of incidental mail from that engagement. The boundary isn&#8217;t aspirational \u2014 it&#8217;s enforced by the alias lifecycle.<\/li>\n<\/ul>\n\n\n\n<p>The pattern across all five: the email alias for developers tool is doing the same thing in each case \u2014 providing a per-context address that can be revoked without collateral damage. The contexts are just more varied than the consumer ones, which is why the developer use case rewards a setup that&#8217;s actually programmatic rather than dashboard-driven. For a related comparison framed around consumer mail providers, see our <a href=\"https:\/\/emailalias.io\/blog\/email-alias-vs-gmail-plus-addressing\/\">email alias vs Gmail plus addressing<\/a> deep dive \u2014 the same per-context revocation property is what separates the two there as well. The <a href=\"https:\/\/emailalias.io\/security\/\">EmailAlias.io security page<\/a> covers how our forwarding pipeline handles those revocation events at the infrastructure level.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"final-thoughts\">Final thoughts<\/h2>\n\n\n\n<p>The best email alias for developers in 2026 is the one that meets you at the terminal rather than the dashboard. Four of the five providers above clear that bar; the differences between them come down to whether you want a hosted setup with a clean REST API (EmailAlias.io), an open-source codebase with the option to self-host (SimpleLogin or addy.io), or a full mail provider with a standards-based JMAP surface (Fastmail). The fifth, Apple Hide My Email, is included for honesty about where the Apple-ecosystem default lands \u2014 but it doesn&#8217;t compete on the dimensions that matter for serious programmatic use.<\/p>\n\n\n\n<p>If you&#8217;re starting from scratch and don&#8217;t already have a strong preference, EmailAlias.io&#8217;s free tier (10 aliases, no upsell pressure) is enough to evaluate the API surface in an afternoon. <a href=\"https:\/\/emailalias.io\/pricing\/\">Start with the free tier<\/a>, write the CLI wrapper, point a custom domain at it, and the setup pays itself off the next time you sign up for a SaaS trial \u2014 which for most developers is by the end of the week.<\/p>\n\n\n\n<p>Whatever you pick, the meta-rule from <a href=\"https:\/\/emailalias.io\/blog\/email-alias-portability-guide\/\">our portability guide<\/a> still holds: route your aliases through a domain you own. The day-to-day workflow is identical regardless of provider; the portability property only kicks in if the underlying namespace is yours. That single decision \u2014 custom domain over provider domain \u2014 does more for the longevity of your alias setup than any of the per-provider feature differences in this guide.<\/p>\n\n\n\n<h2 id=\"frequently-asked-questions\">Frequently asked questions<\/h2>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-question-1780552436205\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is the best email alias for developers in 2026?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>EmailAlias.io is the best email alias for developers if you want a hosted setup with a clean, documented REST API and custom-domain support on Premium. addy.io is the strongest free-tier choice with first-party CLI; SimpleLogin is the strongest open-source pick with a serious self-host story. The right answer depends on whether you value hosted convenience, self-hostability, or being part of a wider mail provider.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780552458473\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Why do developers need a separate email alias setup at all?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Developers sign up for ten to thirty new services a quarter \u2014 SaaS trials, OSS registries, CI providers, vendor portals. Sharing a single Gmail across all of them turns one breach into a credential-stuffing risk against every other. An email alias for developers gives each service its own address, revocable in isolation, with leak attribution as a side effect.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780552477125\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Do I need an API to use an email alias as a developer?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Practically yes. Without an API, you&#8217;ll be doing dashboard clicks every time you sign up for something new \u2014 friction that breaks the discipline within a few weeks. A documented REST or JMAP API, plus either a first-party CLI or a short shell wrapper, are the difference between an alias setup you actually use and one that lapses.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780552490467\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can I self-host an email alias service?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes \u2014 SimpleLogin and addy.io are both open-source under AGPL with documented self-host paths on Docker or a plain VPS. EmailAlias.io and Fastmail are hosted-only. Apple Hide My Email is iCloud-only. Self-hosting trades convenience for a stronger long-term portability story.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780552500444\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Does an email alias for developers work with GitHub commits and npm publishes?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes. The alias acts as a normal email address as far as Git, npm, Cargo, and other package metadata are concerned. Most developers use a per-project alias as the maintainer address \u2014 it&#8217;s recoverable if compromised and revocable when the project winds down. GitHub&#8217;s no-reply commit email is the equivalent for the GitHub identity itself.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780552513341\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">How many email aliases should a developer maintain?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Typical working developers settle on 50 to 200 active aliases over a couple of years \u2014 one per significant SaaS account, one per OSS project, one per CI integration, one per freelance client. The free tier of any reputable provider covers the first 10 to 20; Premium or Pro covers the rest. With a custom domain in front, the count is mostly limited by labelling discipline rather than provider caps.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780552533321\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What happens to my aliases if the provider shuts down?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Aliases registered under the provider&#8217;s own domain die when the provider does. Aliases on a custom domain you own survive \u2014 you re-point the MX record at a new provider and the same addresses continue working. The custom-domain decision is the single most important portability choice; we cover it in the email alias portability guide.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780552559110\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Is using an email alias for developers different from Gmail plus addressing?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes. Plus addressing labels your inbox but leaves the real address visible \u2014 spammers strip the +tag in one regex. A real alias hides the underlying inbox entirely, is revocable per-service, and works at sign-up forms that reject the &#8220;+&#8221; character. We compare them in detail in our Email Alias vs Gmail Plus Addressing post.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The best email alias for developers isn&#8217;t the one with the prettiest landing page \u2014 it&#8217;s the one with a documented API, a working CLI, and custom-domain support that survives&#8230;<\/p>\n","protected":false},"author":3,"featured_media":126,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[6,7,9],"tags":[],"class_list":{"0":"post-125","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-comparisons","8":"category-developers","9":"category-productivity"},"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/emailalias.io\/blog\/wp-content\/uploads\/2026\/06\/og-best-email-alias-for-developers.jpg?fit=1200%2C630&ssl=1","jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":129,"url":"https:\/\/emailalias.io\/blog\/openapi-email-alias\/","url_meta":{"origin":125,"position":0},"title":"OpenAPI Email Alias: API-First Forwarding Setup","author":"Troy Hunt","date":"June 5, 2026","format":false,"excerpt":"An OpenAPI email alias is the same primitive as any forwarding alias \u2014 a separate address that routes inbound mail to your real inbox \u2014 but described by a machine-readable OpenAPI Specification document so you can generate clients, mock the API offline, and wire alias creation into any tool that\u2026","rel":"","context":"In &quot;AI Integrations&quot;","block_context":{"text":"AI Integrations","link":"https:\/\/emailalias.io\/blog\/category\/ai-integrations\/"},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/emailalias.io\/blog\/wp-content\/uploads\/2026\/06\/og-openapi-email-alias.jpg?fit=1200%2C630&ssl=1&resize=350%2C200","width":350,"height":200,"srcset":"https:\/\/i0.wp.com\/emailalias.io\/blog\/wp-content\/uploads\/2026\/06\/og-openapi-email-alias.jpg?fit=1200%2C630&ssl=1&resize=350%2C200 1x, https:\/\/i0.wp.com\/emailalias.io\/blog\/wp-content\/uploads\/2026\/06\/og-openapi-email-alias.jpg?fit=1200%2C630&ssl=1&resize=525%2C300 1.5x, https:\/\/i0.wp.com\/emailalias.io\/blog\/wp-content\/uploads\/2026\/06\/og-openapi-email-alias.jpg?fit=1200%2C630&ssl=1&resize=700%2C400 2x, https:\/\/i0.wp.com\/emailalias.io\/blog\/wp-content\/uploads\/2026\/06\/og-openapi-email-alias.jpg?fit=1200%2C630&ssl=1&resize=1050%2C600 3x"},"classes":[]},{"id":145,"url":"https:\/\/emailalias.io\/blog\/email-forwarding-api\/","url_meta":{"origin":125,"position":1},"title":"Email Forwarding API: Endpoints, Auth, and Use Cases","author":"Troy Hunt","date":"June 9, 2026","format":false,"excerpt":"An email forwarding API is the HTTP interface that lets you create, list, toggle, and revoke email aliases programmatically \u2014 without ever opening the alias provider's dashboard.
