If you don't feel good about giving Mopapp your mailbox credentials (for stores where we can't download the CSV or use an official API, but must parse the notification mails), here's a suggestion: create a dedicated mailbox to be used just for the store emails, and nothing else. This way you won't give us access to anything more than we would see if you gave us the store's control panel credentials.

Rest assured, anyway, that our automated process searches for and parses only mails that match the pattern of the store's notification mails, and it completely skips all other mails.
