Which apps support which services?
All our apps were easy to set up and start using, but there are key differences in the services they support. It’s worth noting that if you are using two-step verification on iCloud or Gmail then you’ll need to generate an app-specific password for your mail app: you can’t use the same password in two different email applications. You can have up to 25 app-specific passwords in operation at any time.
Airmail supports IMAP (including Google), POP3 and Exchange, as does Outlook; Mailbox will only connect to iCloud or Gmail; Postbox works with IMAP, POP, RSS and newsgroups; and Thunderbird will work with pretty much anything ever invented. Unibox is IMAP-only, so you can use it with the likes of Gmail and iCloud but not POP3 mail if you like to keep things old-school.
If you use Gmail and have lots of labels set up, Mailbox ignores them: it has its own lists, which appear in Gmail as sub-labels of the Mailbox label. To use existing labels, you’ll need to nest them inside the Mailbox label.
Mailbox keeps the choice simple: you can use iCloud, or you can use Gmail. That’s it.
