Twitter is spamming me

A few months ago I decided to cancel my Twitter account (yes, it was fun for a while but I've decided it doesn't work for me). Ever since Twitter is spamming me with 3/4 emails a week offering me to restore my account. I do not want to restore my account and I do not want to receive any of these emails anymore. I've emailed support but no action has been taken. Can someone give me a pointer as to where I can stop this?

This is the message:

Hi there, <name>!

Glad to see you decided to restore your Twitter account.
