You'll need to make sure IMAP is enabled in Gmail Settings, but if you're already using Gmail with an email program, then it's probably already enabled.
You can use unlimited email accounts with MailWasher, so that includes any Gmail, Outlook.com, Yahoo and every other kind. MailWasher makes it easy to check them all at once, or just a few at a time.
Being able to view everything about your messages before they get to your computer so you can determine if they’re really spam, scams or good email is very helpful. This means you can delete unwanted messages at the server so you only get the email you want.
MailWasher lets you view the email safely in plain text, but you can also inspect who it’s really from, who owns the company who sent it (WHOIS report) and all the hidden links.
Given that you can’t afford to lose any legitimate email, MailWasher lets you have the final say on it before letting you ‘Wash’ the spam away.
