Heads up! Gmail will no longer support checking emails from third-party accounts via POP. https://support.google.com/mail/answer/16604719?hl=en
Learn about upcoming changes to Gmailify & POP in Gmail - Gmail Help

Gmail will start removing support for the following features: Gmailify: This feature allows you to get special features like spam protection or inbox organization applied to your third-party email

@nixCraft worth clarifying that they're killing two different things here.

The mobile app will no longer support POP3 with 3rd party mail accounts - that's fine, just switch to IMAP.

They're also removing the "Check mail from other accounts" feature in the web interface that pulls mail from other accounts into your Gmail inbox. This is (was) the only reliable way to "forward" mail into your Gmail inbox.

The Death of Email Forwarding - Mythic Beasts

@beasts @nixCraft

Does this mean my custom email domain where I get mail sent to can no longer be forwarded to my gmail??

I used it to get email, and I used gmail to respond to those emails in kind...

If so, this is huge news...

@ChrisFerguson @nixCraft you can still forward email to Gmail, but it's not completely reliable, and we do see Gmail reject legitimate forwarded email. The "check mail from other accounts" used to be a better way to do forwarding.

@beasts
I have been forwarding my email from my personal domain to other services for 25 years. To Gmail since I got an account in 2004. I suffered Gmail rejecting legitimate forwarded email a couple of years ago. So I moved to pull them with POP from my personal domain into my Gmail account.

But in 2026 all this is gone, right? There is no reliable way to use Gmail (desktop web) to get the emails from my domain, right?

@ChrisFerguson @nixCraft

@jjimenezshaw @ChrisFerguson @nixCraft That's our understanding. It may be with the increased adoption of DKIM, forwarding works better than it used to, but I wouldn't bet on it.
