How do I delete all 20k e-mails?

select all and delete them

I have so much I give up and make a new email :)

My spam is set to delete once a week as is my trash. Most browsers will let you delete a page at a time. It still will take a while, so do not let it build up again.

If you receive unwanted mail, then you should 'unsubscribe' these mails. Normally, in most of the mails, in the last there is option to 'unsubscribe', if you unsubscribe, you will stop receiving such mails in future.

I think you can just select all the times and deleted manually.

Select all and delete them as that is the only possible way. Don't worry I have faced this problem before and after that incident I have cultivated the habit of checking my mail daily and deleting the unwanted keeping it clean.

There should be a button on there. But some of my email accounts do not, but do have a thing where you can check and delete all emails on that page. Good luck

I select all and then delete, but that usually only deletes a page at a time, but you can do it.I am preparing to delete one of my accounts, but it had a lot of e-mails I wanted to keep, so it took longer, but I was able to forward the e-mails I wanted to keep to anther address, then I selected all on a page and then deleted them. In the future, I suggest you delete emails you know you don't want to keep.

Well, so it gradually, but if you have time you can do it in one day.

This also happens with me. Lot of emails in inbox.
