Every email account you add to AirMail will be signed up for their spam. Youre not given a way to not subscribe in the first place, which makes this illegal. Deleting the app and demanding a refund from Apple.
Also, its buggy. Save a draft? All of its contents will be gone when you open it up again. Years ago they regularly obliterated my drafts because of a bug and told me no bug existed. Now its happening again. You cant rely on this POS with your email, itll just disappear.
