Given that Gmail does not have, and never has had, infinite free storage it seems quite hard for it to follow the same path... It's already there.

Specifically, Gmail had 1GB quota at launch. These days you have 15GB combined across Drive, Gmail and Photos for free, and paid plans if you need more space.

Back in the day Gmail was growing its free space nonstop. No longer.

Didn’t they use to have a counter on the home page telling you how many millions of megabytes were still available for gmail storage?

I think gmail has lower chance of this happening because google needs to feel the "pulse" on whats happening in the world by reading your email. Photos are quite repetitive and they done enough of AI training.

It's only going to get more difficult to switch to another email provider as time passes, you should switch now.

I would even go as far as to suggest setting up your email with your own domain. This way switching providers is as easy as just changing a few DNS settings.

I've been running that setup for a few years now and it has been flawless. Spam is almost entirely gone, with a catch-all address I can simply sign up to websites with <website name>@mydomain, makes it easy to track down if one of them ends up doing shady things with your mail!

I have a few domain names but I don't know which one I should use to replace my usual [email protected].

Should I go for [email protected] or [email protected] ?

I personally have a "vanity" domain that spells out my last name (the TLD forms the last two letters). So I just have <firstname>@<domain> for personal stuff, and then for example git@<my domain> for github, spotify@<my domain> for spotify etc.

The [email protected] approach seems like a clean way to do it as well.

That would decimate google user accounts if it happened.
