Email providers
Pick your provider for its full set of guides — login help, server settings, security, and account recovery.
Every provider below has the same shelf of guides written for it, so you are not reading advice meant for a different service: how to sign in and what to do when that fails, how to get back into an account whose password is gone, the IMAP, POP and SMTP settings its mail servers expect, and how to lock the account down.
Not sure which one
Work out who really runs your mailbox
A work address or your own domain rarely says who is behind it: you@yourcompany.com could be Google Workspace, Microsoft 365 or something your host runs. The finder reads the domain’s mail servers and tells you which service to follow.
The same shelf, every provider
What each provider hub holds
01
Signing in
The real sign-in address, what the provider asks for, and the usual reasons a correct password is still refused.
02
Getting back in
Password resets and account recovery — including where recovery genuinely is not possible, which we say rather than imply otherwise.
03
Server settings
IMAP, POP and SMTP hostnames, ports and encryption, plus whether the provider needs an app password instead of your normal one.
04
Security and fixes
Two-factor setup, spotting fakes sent in that provider’s name, and what to check when mail stops sending or arriving.
