You can block certain emails by adding the sender (or patterns like domains or keywords) to a block or filter list in your email service, then automatically sending those messages to spam, trash, or another folder. Most modern inboxes (Gmail, Outlook, Apple Mail, Yahoo, etc.) let you do this with just a few clicks on a message from that sender.

How blocking usually works

  • Blocking a sender does not stop them from sending; it just makes their messages skip your inbox and go to spam or trash automatically.
  • You can usually block by:
    • Specific email address
    • Entire domain (like @annoyingsite.com)
    • Certain words in subject or body using filters/rules.

Typical steps in popular email services

These are the common patterns across major providers:

  • Gmail (web and app)
* Open an email from the sender.
* Click the three-dot **More** menu near the reply button.
* Choose “Block [sender]” and confirm.
* For more control, use **Filters** to say “if From contains this address or domain → Delete or Skip inbox”.
  • Outlook / Outlook.com
* Right‑click a message and choose **Block > Block sender**, or use **Junk > Block**.
* In web Outlook, you can also go to **Settings → Junk email** and add addresses/domains to **Blocked senders and domains**.
* For complex cases, create a **Rule** : If “From is [address/domain]” or “Subject contains [words]” → Delete.
  • Apple Mail on Mac
* Select a message.
* Click the arrow next to the sender’s name and choose **Block Contact**.
* In Mail settings, you can adjust whether blocked messages go to Trash or stay visible with a block icon.

Smarter filters for stubborn emails

When blocking a single address is not enough (for example, scammers keep changing the “From” email), filters and rules help a lot.

  • Use keywords that always appear:
    • In subject: e.g., “if subject contains ‘ENDURANCE AUTO’ → move to Trash”.
* In body: e.g., “if message content contains ‘exclusive offer for you’ → mark as spam”.
  • Filter by domain :
    • “If From contains @examplepromo.com → Delete message.”
  • Combine conditions:
    • From: newsletter site
    • And subject contains: “sale”
    • Then: Skip inbox and archive.

Forum & “latest trend” angle

In recent forum and Reddit discussions, people often mention that:

  • Simple “block sender” features sometimes feel weak because spammers rotate addresses.
  • Power users rely heavily on:
    • Rules based on text in the content or subject.
    • Domain‑wide blocking.
    • Marking lots of messages as spam so the provider’s automated filters learn faster.
  • There is growing interest in AI‑based email blockers that let you describe in natural language what you never want to see (like “all cold sales pitches” or “all crypto investment spam”), and the tool creates the filters behind the scenes.

Quick multi‑step plan to block certain emails

  1. Identify patterns
    • Same sender, domain, subject style, or repeating phrases.
  2. Block or mark as spam
    • Use the basic “Block” or “Report spam” function on several of those messages.
  1. Create filters/rules
    • Add rules using addresses, domains, or recurring keywords and set action to Delete , Move to spam , or Skip inbox.
  1. Review occasionally
    • Check spam/junk occasionally to rescue legit emails and fine‑tune your rules so they don’t hide important messages.

TL;DR : To handle “how to block certain emails”, start by blocking the sender from an unwanted message, then add rules using domains and keywords so similar emails are auto‑deleted or sent to spam without ever cluttering your inbox.
