Since Gmail is discontinuing its POP3 import feature, I'm looking for a replacement and found Mailporter.io. Their only purpose is to import emails from external mailboxes into Gmail.

Has anyone used this service?

I probably could set up a cronjob using imapsync somewhere, but besides all the faff to get it to work properly and tune everything (e.g., folders, labels, etc.), a family member would be the main user. I thought I'd use something more intuitive for a non-tech person.
