Mail app Inbox kept growing; meanwhile gmail showed 7,000 emails but Mac mail app showed 21,000 emails. It was a disaster. Now it is perfect.

Yesterday I helped a friend who had a problem where her outgoing email account (SMTP server) for a Gmail based email account kept appearing 'Offline' right after she set it up. Even adding the SMTP server manually in Mail didn't help.

You shouldn’t need to do any of the custom SMTP setup within Mail to get a Gmail based email account working in macOS. Now Gmail accounts should be setup just through 'Internet Accounts' in the System Preferences, and the SMTP will be setup automatically.

Removing the account and setting it up again should take care of the issue.

If your SMTP server / Outgoing Mail Account constantly appears 'Offline', here's how to fix it:

Close Mail if it's open now.
Click the Apple menu (upper left corner of your screen) > System Preferences > Internet Accounts.
Select the account with the broken outgoing mail server, and then click the minus sign at the bottom.
Reboot your Mac.
Click the Apple menu > System Preferences > Internet Accounts.
Click Google, and sign into your Gmail based account again.

Update February 26, 2018:

If you're email is still not working after this, in Mail open the Mail menu > Preferences > Accounts and select your Gmail account. Ensure that the little checkbox for Enable this account is checked.

Multi Account

Add as many email accounts of any type your like to Airmail. (Gmail, GSuite, iCloud Mail, Exchange, Office 365, Microsoft Outlook, IMAP and POP3).

Smart Inbox

When you just want to see the important emails, the smart inbox is here for you. It automatically filters out newsletters and other distractions, leaving you with just the crucial messages.

Snooze

When you don't want to deal with an email now, but don't want it in your inbox either, use the snooze function to hide it until it's relevant. From concert tickets to flight confirmations, keep the emails out of the way until you need them.

Unified Inbox

See all of the email in all of your inboxes at once with the unified inbox feature. You can even exclude accounts from this view if you want to.

Privacy Mode

If privacy is paramount then you can enable privacy mode which will process all the data locally on your device. Privacy mode also blocks tracking pixels, and prevents images from loading automatically.
