u/mailavion

My subscription will shortly expire, and I won't be renewing it. All the important emails in that account have been backed up locally by myself. I've moved out my domains and they are set up and working with the new provider, I've cleared out the file storage manually. Should I just let the subscription expire, and then Fastmail will delete all the emails, or should I do it myself? Deleting the emails myself could prove to be time consuming.
