For folks spying on competitors' emails, use this gmail hack

If you want to spy on multiple competitors' email series or use them for inspiration / swipe...

To keep things neat & tidy, there's no need to sign up for each list using a different email address as that's too much hassle.

If you use Gmail / Workspace, here's a hack.

Append "+" after your username.

E.g. Your email address is john@gmail .com —> use john+competitor1@gmail .com

All email messages will still end up in the same inbox (john@gmail .com)

Then create a Label "Competitor1" in Gmail. After that create a Filter that routes all email messages that go to [john+competitor1@gmail .com] to the "Competitor1" Label.
