Email aliases for your team
Custom domains with SPF/DKIM/DMARC. Send and reply from any alias. Sender-risk filtering on inbound. Per-alias audit log. Run as many addresses as the business needs without spinning up mailboxes.
Premium ($4/mo) with 7-day free trial. Custom domains and send-and-reply are Premium-only.
What teams get out of it
Custom domains, fully authenticated
Add up to 5 of your business domains. Add the TXT, MX, SPF, DKIM, and DMARC records once; verify in the dashboard. Aliases look like sales@yourbrand.com, not aliases@some-vendor.io.
Send and reply from any alias
Reply to a customer email and the recipient sees the alias as the sender — your real email never leaks. Critical for client communications, vendor relationships, and anything that needs to look on-brand.
Sender-risk filtering on inbound
Every inbound message is scored on phishing signals — risky TLDs, typosquatting domains, suspicious keywords. High-risk senders are flagged in the dashboard before they reach your team's inbox.
Per-alias audit log
Every forwarded message is logged with sender, timestamp, and delivery status. When you need to prove a vendor email was received (or never was), the answer is one click away.
Common business use cases
Patterns we see most often across sales, support, procurement, and partnerships teams.
Sales: aliases per lead source
sales-tradeshow@, sales-webinar@, sales-cold@ — track which marketing channel a lead came from from the address alone. Disable the alias if a channel starts attracting spam or scraping.
Support: ticket-pipeline aliases
Spin up support-billing@, support-onboarding@, support-vip@ as routing aliases that forward to the right human or queue. No need to provision new mailboxes in your mail provider.
Procurement / vendor management
vendor-aws@, vendor-stripe@, vendor-slack@ — one alias per vendor relationship. When AWS sends an invoice, you can see it; if the alias starts getting spam after a vendor change, you know exactly who leaked your contact info.
Press / partnerships / careers
Dedicated aliases for outward communications (press@, partnerships@, careers@) that look professional, route to the right inbox, and can be retired without breaking anything else.
Marketing forms + signup confirmations
Capture confirmations for webinars, gated downloads, and trial signups on dedicated aliases instead of cluttering the marketing team's primary inbox.
Set up in 15 minutes
Most of the time goes into the DNS records — once those propagate, the rest is a few clicks per alias.
- 1
Verify your business domain
Add your domain in the EmailAlias dashboard, then add the TXT, MX, SPF, DKIM, and DMARC records to your DNS provider. Hit verify — most DNS hosts propagate in minutes. The dashboard shows which records pass and which still need work.
- 2
Decide your alias scheme
Pick a convention: <function>@yourdomain.com (sales@, support@, vendor-stripe@), <employee>-<role>@yourdomain.com (jane-sales@), or random tokens (x7k9m@) for higher anonymity. The scheme is up to you — local-parts are unrestricted.
- 3
Mint your first aliases
Either from the dashboard one at a time, or programmatically via the REST API for bulk setup. API access is included on Premium ($4/mo, 7-day free trial).
- 4
Configure forwarding destinations
Add and verify the inboxes that should receive forwarded mail — primary plus additional team mailboxes. Each alias can route to a different destination, so support tickets and sales leads don't end up in the same inbox.
- 5
Enable send & reply
From the dashboard, reply to any forwarded message — the response goes out from the alias address, not your real one. The customer sees a clean from: header; you keep a personal inbox they never see.
Frequently asked questions
The questions we get most often from teams evaluating EmailAlias for business use.
What's the best email alias service for business?
Custom-domain support is the bar for business use — you don't want client-facing aliases on someone else's brand. EmailAlias.io, SimpleLogin, and Addy.io all support real custom domains on their paid tiers. EmailAlias.io adds suspicious-sender intelligence, AES-256 at rest, and a REST API + MCP server, which most businesses care about more than self-hosting. Firefox Relay and DuckDuckGo Email aren't great fits for business — neither supports real custom domains.
Can I use my own domain for email aliases?
Yes. Premium users can add up to 5 custom domains with full SPF, DKIM, and DMARC verification. Create professional aliases like contact@yourdomain.com while maintaining complete privacy.
Do you support SPF, DKIM, and DMARC?
Yes. All aliases — including custom domain aliases — support SPF, DKIM, and DMARC authentication. This ensures your forwarded emails have maximum deliverability and aren't flagged as spam.
What does Premium include?
Unlimited aliases, up to 5 custom domains, unlimited verified forwarding inboxes (so each alias can route to the right mailbox), send & reply from any alias, real-time leak detection with exposure analytics, and priority processing — all for $4/month or $35/year (save 27%).
Can I reply from my alias?
Yes — Premium feature. When you receive a forwarded email, you can reply from your real inbox and EmailAlias routes the reply back through your alias, so the recipient only sees the alias address, never your real email. Free accounts can receive but not send; upgrade to enable replies.
Can I move my aliases between providers?
Aliases on a shared provider domain (e.g. @emailalias.io) aren't portable — they live on our domain and stay with us. Aliases on a custom domain (yourdomain.com) are fully portable: you keep the domain, point its MX records at a new provider, re-create the same local-parts on their side, and the addresses keep working — provided the new provider supports custom local-parts (most do; some only issue random codes). Custom domains are a Premium feature on EmailAlias, but for anyone who plans to use aliases long-term, it's vendor-independence insurance worth having.
Run your business on real custom-domain aliases
