What is the best email programme to use on iPad Pro ios11.1 to get rid of spam

Most email apps can learn what spam to get rid of as long as you remove/move it to your email services supplied spam folder.

After awhile you should not be getting spam, as it will all go to the email service’s spam folder where you can get rid of this anytime.

There are no email services that are spam-free and you will have to train any email client for iOS to automatically delete any unwanted email or spam mail you no longer want to receive in your email client/service inbox.

Good Luck to You!

I do not know of a single iOS email app where the app itself does any spam filtering at all. Spam filtering with gmail, yahoo, iCloud, etc is all done on the server side, not in the mail apps themselves.

You can login to your gmail, yahoo, iCloud or whatever service account online and see what spam settings they offer. Gmail, if set to IMAP will learn from whatever you put in the IMAP spam folder (make sure you have your iOS mail app set to save spam to the server’s folder and not a local folder). So does iCloud. Yahoo will also do so, but if using a free yahoo email account that is an advertisement based account, so it will inherently have a ton more cr8p emails than some other free accounts.

For optimal email spam control, I recommend getting a web hosting account, registering your own domain(s) and using those for email. My hosting service offers both algorithmic auto-spam filtering at various stringency levels, as well quite complex spam filtering rules (wild cards, Boolean strings, etcj as well as both blacklists and whitelists. Of all my email accounts (iCloud, yahoo, several gmail, and my own domain based accounts) by far the one with the least inbox received spam email are my own domain based ones, since I have by far more control over them than any others.
