Hey, I just figured it out. Go into any app, pull up your keyboard and start typing. When the wrong email appears in the auto fill area, tap on the arrow to expand the area. You should see 'Auto replace' at the bottom of the drop down, with an on-off button. Turn it off, tap and hold the incorrect email address, select 'ok' in the 'Remove' dialogue box, and turn auto replace back on. No more wrong email auto filling. :-)

You sir, are a genius!! Many thanks :-)

I LOVE YOU! That is the fix. So elegant. Thank you.

The auto correct would be stored in your keyboard app, not Google or Gmail. Try clearing the cache / data of your keyboard app and see if that helps. I use Swiftkey, so I'm not sure what the name of the app is for the stock keyboard but I'm sure someone here or on XDA could point that out if you need it.

This worked. Deleting contacts from Gmail contact list did not.
Settings>Apps>Gboard>Clear cache
Problem solved.

MY Contacts VS OTHER Contacts Labels and auto-complete

Once I cleared out the old auto-complete email addresses (thanks DLeoLion!) there was still a lot of junk from the Other Contacts folder in Gmail (Web) in the auto-complete list on my phone.
When you create a new contact it is added to My Contacts.
My Contacts phone numberes are synced with the Contacts App on my phone.
Other Contacts phone numbers are NOT synced to phone.
For years I've have been moving old contacts out of My Contacts into Other Contacts to keep phone contacts list tidy.
BUT Gmail scrapes all the email address info from Other Contacts and adds it to the auto-complete list on phone.
I wanted to clear these old email addresses from auto-complete too, here's what I did:

1) Tidied all old contacts out from My Contacts to Other Contacts
2) Some people in My Contacts have several email addresses. I moved the extra email addresses into their description text box. Email addresses in the description box are NOT synced to your phone.
3) Exported Other Contacts to a 2nd Gmail account:
Other Contacts > More > Export > Other Contacts > Google CSV
then imported into a second Gmail account:
My Contacts > More > Import ...
4) Deleted Other Contacts from 1st email account.
5) Un-installed/Re-installed Gmail App
6) Voila all nice and tidy!

If i want an old email address I will log into my 2nd email account on the web.
You could add the 2nd account to your phone contacts temporarily, but you'll probably drag all the old email addresses into the auto-complete list.

Hope that may be of use to someone

If someone knows a simpler way to do this, please post )

Thanks DLeoLion! Worked great on Android 8.1 on my Pixel 2 XL.

Here's why I was initially skeptical to try it, though: I am NOT syncing my contacts to my phone! Yet, that was the fix. Very weird operating behavior, but it did it.

I know Blackberry is old, old news, but I still like (and pay for) their Hub.

Just installed it on my new Google Pixe 3. Having the same problem with Hub when sending emails, but found the answer there.

If you don't use Hub then this isn't as useful I guess. In "Contacts" (part of Hub) go to Settings and "Manage Suggested Recipients". You can search for the email you are having problems with and delete the 2 or 3 (or in my case 6) old/bad ones.

Then I tried email again and volia, no more old/bad suggestions, only the good one.

It might help a few older guys like me who still love Hub.

This is the correct answer. Works on my Galaxy S9 too.Many thanks Sarah, this has been bugging me on my old S5 phone as well as my new one. Now it's fixed! What Sarah means is press and hold on the incorrect prediction which is in blue till the warning pops up. I had to use a magnifying glass to read it but if i had turned the phone to landscape orientation I would have read it OK. Thanks again Sarah!
