Deleting emails
is there an easier way to delete over 12,000 emails instead of going to each one to delete?
iPhone XR, iOS 12
If I were in your shoes, considering the quantity of messages you need to delete, I would close the Apple Mail app on your iphone, then open your e-mail provider webmail site on your computer, and do it from there.
When you open the Apple Mail app on your iphone again, give it time to "sync"...
