EmailAlias lets you do exactly that: silence one specific sender (or an entire domain) across your account, so their messages are quietly dropped before they reach you. This guide shows how to block an email sender, how the matching allowlist lets your trusted contacts always get through, and how blocking a sender differs from disabling an alias \u2014 so you reach for the right tool each time.<\/p>\n\n<nav class=\"post-toc\" aria-label=\"Table of contents\">\n  <h2 class=\"post-toc__title\">Table of contents<\/h2>\n  <ol class=\"post-toc__list\">\n    <li><a href=\"#what\">What blocking a sender does<\/a><\/li>\n    <li><a href=\"#how-to\">How to block an email sender<\/a><\/li>\n    <li><a href=\"#allowlist\">The allowlist: always let trusted senders through<\/a><\/li>\n    <li><a href=\"#vs-disable\">Block a sender vs disable an alias<\/a><\/li>\n    <li><a href=\"#dropped\">What happens to blocked mail<\/a><\/li>\n    <li><a href=\"#scope\">When to block an email sender (and the scope)<\/a><\/li>\n    <li><a href=\"#plan\">Plan and limits<\/a><\/li>\n    <li><a href=\"#tips\">Tips for allow and block lists<\/a><\/li>\n    <li><a href=\"#fits\">How blocking fits your wider setup<\/a><\/li>\n    <li><a href=\"#final-thoughts\">Final thoughts<\/a><\/li>\n    <li><a href=\"#faq\">Frequently asked questions<\/a><\/li>\n  <\/ol>\n<\/nav>\n\n<h2 id=\"what\">What Blocking a Sender Does<\/h2>\n<p>Blocking a sender tells EmailAlias to refuse mail from that address \u2014 or that whole domain \u2014 before it&#8217;s forwarded to you. The message is dropped silently: it never lands in your inbox, and the sender receives no bounce, no error, and no hint that they&#8217;ve been blocked. From their side the email looks delivered; on your side it simply never arrives.<\/p>\n<p>That silent drop is deliberate. A bounce message would tell a spammer your address is live and being actively managed, which invites more <a href=\"https:\/\/en.wikipedia.org\/wiki\/Email_spam\" rel=\"noopener\" target=\"_blank\">spam<\/a>. By dropping quietly, blocking closes the door without ringing a bell. It&#8217;s a precise tool \u2014 you&#8217;re removing one specific sender, not touching the alias itself, so every other message to that alias keeps flowing normally. This kind of targeted <a href=\"https:\/\/en.wikipedia.org\/wiki\/Email_filtering\" rel=\"noopener\" target=\"_blank\">email filtering<\/a> is exactly what you want when a single contact turns sour.<\/p>\n<aside class=\"post-keytakeaway\"><strong>Key takeaway:<\/strong> Blocking a sender silently drops their mail before it reaches you \u2014 no bounce, no error, no tip-off. It targets one sender or domain, so the alias itself and every other sender keep working normally.<\/aside>\n\n<h2 id=\"how-to\">How to Block an Email Sender<\/h2>\n<p>There are two easy ways to block an email sender, depending on where you&#8217;re starting from.<\/p>\n<p><strong>From a message that already reached you.<\/strong> This is the quickest:<\/p>\n<ol>\n  <li><strong>Open your logs.<\/strong> Go to the activity view where your forwarded messages are listed.<\/li>\n  <li><strong>Find the message from the sender you want gone.<\/strong> Each forwarded email shows who sent it.<\/li>\n  <li><strong>Click Block.<\/strong> A single click adds that sender&#8217;s domain to your blocklist. From then on, mail from that domain is dropped before it reaches you, and the message row shows it&#8217;s now blocked.<\/li>\n<\/ol>\n<p><strong>By adding an entry directly.<\/strong> If you already know the address or domain you want to stop:<\/p>\n<ol>\n  <li><strong>Open the Spam filters page<\/strong> in your dashboard, which has an Allowlist panel and a Blocklist panel.<\/li>\n  <li><strong>Add to the Blocklist.<\/strong> Type a full email address (to block one specific sender) or a bare domain (to block everyone at that domain), and add it.<\/li>\n  <li><strong>Done.<\/strong> Any future mail matching that entry is dropped silently. You can remove the entry at any time to un-block.<\/li>\n<\/ol>\n<p>Blocking a whole domain is the heavier hammer \u2014 useful when an entire service or a spammy marketing platform is the problem \u2014 while blocking a single address surgically removes just one correspondent. You can keep up to a large number of entries, so your blocklist can grow as needed. If you&#8217;d rather stop <em>all<\/em> mail to a given address instead of one sender, that&#8217;s a job for <a href=\"https:\/\/emailalias.io\/blog\/disable-an-email-alias\/\" rel=\"noopener\" target=\"_blank\">disabling the alias<\/a> \u2014 more on that difference below.<\/p>\n<aside class=\"post-keytakeaway\"><strong>Key takeaway:<\/strong> Block a sender in one click from a forwarded message (it blocks their domain), or add a specific address or domain to the Blocklist on the Spam filters page. A full address blocks one sender; a bare domain blocks everyone there.<\/aside>\n\n<figure class=\"wp-block-image size-large\">\n  <img data-recalc-dims=\"1\" src=\"https:\/\/i0.wp.com\/emailalias.io\/blog\/wp-content\/uploads\/2026\/09\/block-an-email-sender-example.jpg?resize=1080%2C608&#038;ssl=1\"\n       alt=\"block an email sender: a stamped letter set aside into a blocked tray while others pass through\"\n       width=\"1080\" height=\"608\" loading=\"lazy\" decoding=\"async\" \/>\n  <figcaption>Blocking a sender is like pulling one letter out of the pile and setting it aside \u2014 the rest of your mail flows through untouched.<\/figcaption>\n<\/figure>\n\n<h2 id=\"allowlist\">The Allowlist: Always Let Trusted Senders Through<\/h2>\n<p>Blocking has a mirror image: the allowlist. Where the blocklist stops specific senders, the allowlist guarantees specific senders always get through. Add a trusted address or domain to your allowlist and its mail bypasses the spam filter entirely \u2014 it&#8217;s always forwarded, never held back or marked, no matter what.<\/p>\n<p>This solves the opposite problem to spam: important mail being caught by mistake. If a bank, a client, or a service you rely on ever risks being filtered \u2014 because their messages look unusual, or come from a domain with a mixed reputation \u2014 allowlisting them makes sure their mail reaches you every time. It&#8217;s the safety valve that lets aggressive spam filtering stay aggressive without ever costing you a message that matters. Together, the allowlist and blocklist give you a simple rule for both ends: this sender always in, that sender always out.<\/p>\n<aside class=\"post-keytakeaway\"><strong>Key takeaway:<\/strong> The allowlist is the opposite of the blocklist: senders you add to it always get through, bypassing the spam filter. Use it for banks, clients, and services you can&#8217;t afford to have filtered \u2014 a safety valve against important mail being caught by mistake.<\/aside>\n\n<h2 id=\"vs-disable\">Block a Sender vs Disable an Alias<\/h2>\n<p>Blocking a sender and disabling an alias both stop unwanted mail, but they work at different levels. Choosing the right one keeps your setup tidy.<\/p>\n\n<figure class=\"wp-block-table\"><table><caption>Block an email sender vs disable an alias \u2014 what each stops and when to use it<\/caption>\n  <thead>\n    <tr><th><\/th><th>Block a sender<\/th><th>Disable an alias<\/th><\/tr>\n  <\/thead>\n  <tbody>\n    <tr><td>What it stops<\/td><td>One sender or domain<\/td><td>Everything to that alias<\/td><\/tr>\n    <tr><td>Scope<\/td><td>Across all your aliases<\/td><td>That one alias only<\/td><\/tr>\n    <tr><td>Other mail to the alias<\/td><td>Still arrives<\/td><td>All stopped<\/td><\/tr>\n    <tr><td>Best when<\/td><td>One sender on a shared alias goes bad<\/td><td>The whole address has been leaked or is done<\/td><\/tr>\n  <\/tbody>\n<\/table><\/figure>\n\n<p>The rule of thumb: if an alias is still useful but <em>one<\/em> sender on it is a nuisance, block that sender. If the whole address has leaked or you&#8217;re finished with it, disable the alias. For example, if a shop you still want emails from gets bought by a spammy marketer who starts blasting you, block that marketer&#8217;s domain and keep the alias. But if an alias you gave one shop starts getting mail from dozens of strangers, the address itself has leaked \u2014 disable it.<\/p>\n<aside class=\"post-keytakeaway\"><strong>Key takeaway:<\/strong> Block a sender when an alias is still useful but one correspondent has gone bad; disable an alias when the whole address has leaked or you&#8217;re done with it. Blocking is surgical (one sender), disabling is total (the whole address).<\/aside>\n\n<h2 id=\"dropped\">What Happens to Blocked Mail<\/h2>\n<p>When a blocked sender emails you, the message is stopped at the door and dropped \u2014 it isn&#8217;t forwarded, isn&#8217;t stored for you to read, and doesn&#8217;t generate a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Bounce_message\" rel=\"noopener\" target=\"_blank\">bounce message<\/a> back to the sender. The only trace is a line in your activity log noting that a message was blocked and why, so you can see the filter working and reverse it if you ever change your mind.<\/p>\n<p>This &#8220;silent drop&#8221; behaviour is the same approach serious <a href=\"https:\/\/en.wikipedia.org\/wiki\/Anti-spam_techniques\" rel=\"noopener\" target=\"_blank\">anti-spam techniques<\/a> use, and it&#8217;s on your side: spammers learn nothing, legitimate senders you&#8217;ve blocked by choice simply stop reaching you, and you keep a record either way. It&#8217;s worth knowing that some senders are also blocked automatically \u2014 for instance, if you ever mark a forwarded message as spam through your own mail provider, or a domain floods you, EmailAlias can add it to your block list for you, so the worst offenders are handled without you lifting a finger.<\/p>\n<aside class=\"post-keytakeaway\"><strong>Key takeaway:<\/strong> Blocked mail is dropped silently \u2014 not forwarded, not stored, no bounce to the sender \u2014 with only a log line recording it so you can review or reverse it. Some abusive senders are also blocked automatically after complaints or floods.<\/aside>\n\n<h2 id=\"scope\">When to Block an Email Sender (and the Scope)<\/h2>\n<p>Reach for the blocklist whenever a specific sender is the problem rather than the address itself:<\/p>\n<ul>\n  <li><strong>A persistent spammer<\/strong> who keeps emailing one of your aliases despite the alias still being useful for other mail.<\/li>\n  <li><strong>A marketing platform<\/strong> that a company you deal with uses to blast you \u2014 block the platform&#8217;s domain and keep the company&#8217;s real messages.<\/li>\n  <li><strong>A single bad actor<\/strong> \u2014 one address sending you unwanted mail that you want gone without disrupting anyone else.<\/li>\n<\/ul>\n<p>One important detail to understand: your allow and block lists are <strong>account-wide<\/strong>, not tied to a single alias. When you block a sender, they&#8217;re blocked from reaching <em>any<\/em> of your aliases, and an allowlisted sender is trusted across all of them. This is usually exactly what you want \u2014 if a sender is a spammer, you don&#8217;t want them getting in through a different alias \u2014 but it&#8217;s worth knowing, so you don&#8217;t expect a block to apply to just one address. If you genuinely need per-address control, that&#8217;s where separate aliases and the disable switch come in, working alongside your global block and allow lists as covered in our guide on <a href=\"https:\/\/emailalias.io\/blog\/how-to-stop-spam-emails\/\" rel=\"noopener\" target=\"_blank\">how to stop spam emails<\/a>.<\/p>\n<aside class=\"post-keytakeaway\"><strong>Key takeaway:<\/strong> Block a sender when one correspondent is the problem but the alias is still useful. Remember the lists are account-wide: a blocked sender can&#8217;t reach any of your aliases, and an allowlisted one is trusted everywhere \u2014 which is usually exactly what you want.<\/aside>\n\n<h2 id=\"plan\">Plan and Limits<\/h2>\n<p>A few practicalities:<\/p>\n<ul>\n  <li><strong>Allow and block lists are a Premium feature.<\/strong> Managing your own trusted and blocked senders is part of <a href=\"https:\/\/emailalias.io\/pricing\/\" rel=\"noopener\" target=\"_blank\">Premium<\/a> ($4\/month).

The two work best together.<\/li>\n<\/ul>\n<aside class=\"post-keytakeaway\"><strong>Key takeaway:<\/strong> Block domains for whole-service problems and addresses for individuals, allowlist your critical senders early, block before deleting a still-useful alias, and pair the lists with per-service aliases for complete control.<\/aside>\n\n<h2 id=\"fits\">How Blocking Fits Your Wider Setup<\/h2>\n<p>Blocking senders is one tool in a small kit that works best together. The foundation is using an <a href=\"https:\/\/emailalias.io\/blog\/what-is-an-email-alias\/\" rel=\"noopener\" target=\"_blank\">email alias<\/a> for each service, so every stream of mail is separate and traceable in the first place. When you <a href=\"https:\/\/emailalias.io\/blog\/how-to-create-an-email-alias\/\" rel=\"noopener\" target=\"_blank\">create an alias per signup<\/a>, a spam problem is already narrowed to one relationship \u2014 and from there your allow and block lists give you the fine control to trust or stop individual senders across everything.<\/p>\n<p>These lists also complement the automatic defences running in the background. If an address you gave one company suddenly attracts mail from strangers, that&#8217;s a leak, and EmailAlias&#8217;s <a href=\"https:\/\/emailalias.io\/blog\/email-leak-detection\/\" rel=\"noopener\" target=\"_blank\">leak detection<\/a> can flag it \u2014 at which point disabling the alias is the right move, not blocking each new sender one by one. The blocklist is for when a specific, known sender is the nuisance; the alias off switch is for when the address itself has gone bad. Think of the allowlist as a personal <a href=\"https:\/\/en.wikipedia.org\/wiki\/Whitelist\" rel=\"noopener\" target=\"_blank\">whitelist<\/a> that guarantees your important contacts, the blocklist as your personal deny list, and per-service aliases as the structure that makes both precise. Used together, they cover every case: trust this sender always, stop that one everywhere, and shut down a whole address when it leaks \u2014 with no collateral damage to the rest of your mail.<\/p>\n<aside class=\"post-keytakeaway\"><strong>Key takeaway:<\/strong> Blocking works best alongside per-service aliases and the automatic defences: aliases keep mail traceable, leak detection flags a compromised address (disable it rather than block each sender), and your allow\/block lists handle known-good and known-bad senders across everything.<\/aside>\n\n<h2 id=\"final-thoughts\">Final Thoughts<\/h2>\n<p>Being able to block an email sender gives you a scalpel to go with the alias&#8217;s off switch. When a whole address has served its purpose or leaked, you disable the alias; but when just one sender turns into a nuisance on an address you still want, you block that sender and keep everything else. Their mail vanishes quietly, they&#8217;re none the wiser, and the rest of your inbox is untouched \u2014 and the matching allowlist makes sure the senders you care about are never caught by mistake. Next time one bad correspondent starts cluttering an alias you rely on, don&#8217;t bin the whole address: block the sender, and carry on.<\/p>\n\n<h2 id=\"faq\">Frequently Asked Questions<\/h2>\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-q-1\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">How do I block an email sender?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>There are two ways. The quickest is from a forwarded message: open your activity log, find the message from the sender you want gone, and click Block \u2014 that adds their domain to your blocklist. Alternatively, open the Spam filters page and add an entry to the Blocklist directly, using either a full email address (to block one sender) or a bare domain (to block everyone there). From then on, matching mail is dropped before it reaches you, and you can remove the entry anytime to un-block.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-q-2\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What happens to mail from a blocked sender?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>It&#8217;s dropped silently.

The only trace is a line in your activity log noting the message was blocked and why, which lets you see the filter working and reverse it if you change your mind.

Your allow and block lists are account-wide, not tied to a single alias, so a blocked sender can&#8217;t reach any of your aliases and an allowlisted sender is trusted across all of them. This is usually what you want \u2014 a spammer shouldn&#8217;t be able to slip in through a different alias. If you need to stop everything to one specific address instead, that&#8217;s a job for disabling that alias, which works alongside your global lists.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-q-4\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What&#8217;s the difference between blocking a sender and disabling an alias?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Blocking a sender stops one specific correspondent (or domain) while the alias keeps receiving everything else \u2014 it&#8217;s surgical. Disabling an alias stops all mail to that whole address \u2014 it&#8217;s total. Use blocking when an alias is still useful but one sender has gone bad; disable the alias when the whole address has leaked or you&#8217;re finished with it. Blocking is account-wide (that sender is out everywhere); disabling affects only the one alias.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-q-5\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is the allowlist for?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The allowlist is the opposite of the blocklist: senders you add to it always get through, bypassing the spam filter entirely.

When you add a blocklist entry, you can enter a full email address to block one specific sender, or a bare domain to block everyone who sends from that domain. Blocking a domain is the heavier option \u2014 useful when an entire service or a spammy marketing platform is the problem \u2014 while blocking a single address surgically removes just one correspondent. The one-click Block button on a forwarded message blocks the sender&#8217;s domain.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-q-7\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Is blocking senders free?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The automatic spam filtering that protects every account runs for free users too, but the manual allow and block lists \u2014 where you choose specific senders to trust or stop \u2014 are a Premium feature ($4\/month). Premium also unlocks related controls and higher limits.
