How to Protect Email from Spam When You Share It Online (2026)

If you post your email address in forums, blogs or social media, spam bots can collect it and flood your inbox. This guide shows how to protect email from spam when you share it online, from protected links to email aliases that you can switch off at any time.

Quick answer: Don’t post your real address as plain text. Share it through a protected link such as Scr.im, use a contact form on your own site, or give out an email alias from Firefox Relay, SimpleLogin or DuckDuckGo Email Protection. If an alias starts getting spam, turn it off without changing your real address.

Why posting your email address attracts spam

Spam bots crawl web pages looking for anything that looks like name@example.com. Once your address lands on their lists, it gets shared and sold, and the spam rarely stops. The safest approach is to never show your real address as plain text that a bot can read.

Ways to protect email from spam online

1. Share a protected link with Scr.im

Scr.im (external site) turns your email address into a short link you can share on X, blogs, forums or anywhere else. To see the address, a visitor has to pass a simple humanity check that automated bots can’t pass. It’s still running in 2026.

2. Use email aliases instead of your real address

An alias forwards mail to your inbox without revealing your real address. If an alias gets spam, you simply disable it.

• Firefox Relay (external site) from Mozilla creates email masks that forward to your inbox.
• SimpleLogin (external site) is an open-source alias service from Proton.
• DuckDuckGo Email Protection (external site) gives you a free @duck.com address and also strips email trackers.

For sign-ups you’ll only use once, see our guide to getting a disposable email address.

3. Use a contact form on your website

If you run a blog or site, a contact form lets readers reach you without your address ever appearing on the page. Add a spam filter or CAPTCHA to the form so bots can’t abuse it.

4. Obfuscate the address if you must show it

• Write it in words, such as “name at example dot com”. It’s not perfect, but it stops the simplest bots.
• If your site uses Cloudflare (external site), its email address obfuscation feature can hide addresses on your pages from bots while showing them to visitors.
• Show the address as an image. Older text-to-image tools have closed, so create the image yourself in any graphics app.

5. Use plus addressing to track leaks

Gmail and many other providers deliver mail sent to name+anything@ to your normal inbox. Use a different tag for each site, and you’ll see who leaked or sold your address. Then filter or block that tag.

What if spam is already arriving?

• Mark messages as spam instead of just deleting them, so your provider’s filter learns.
• Never click links in suspicious emails. Our guide on how to spot a fake phishing email shows the warning signs.
• Unsubscribe only from senders you recognise. For unknown senders, report as spam.

FAQ

Is it safe to post my email address on social media?

It’s best not to post it as plain text. Use a protected link, an alias or your profile’s built-in contact options instead.

What is an email alias?

A separate address that forwards mail to your real inbox. You can turn it off any time without affecting your main account.

Do “name at domain dot com” tricks still work?

They stop simple bots, but smarter scrapers can read them. Aliases and protected links give better protection.

What happened to the other tools in the original post?

The Email Icon Generator, Emailcover and Hidetext services from 2009 no longer offer these tools, so we replaced them with current options.
