I have over 38,000 emails that I want to delete ALL at once. How can I do That?

Hey,

So first open the mail app

Then click the edit button

Then click the select all button

Then the trash button

Then the trash all button

if you have anymore questions feel free to reach out!!

With my email account, I can access it online and easily delete multiple messages. See if this is an option for you.

I agree with kb1951. Using your email accounts web access is the easiest way to do multiple editing tasks.
