I've been a die-hard Sparrow user. But now that iOS 7 is here, and Sparrow will never be updated for it, I'm looking for alternatives. (Also, Sparrow never had an iPad version.) One thing that Sparrow did that no other iOS 7 Gmail client does (that I know of, at least), is automatically replies from the Gmail alias the email is sent to. I forward mail from several different accounts to my Gmail account, and then I've set up Gmail to send mail from those accounts on Gmail's web. With Sparrow, when someone sends an email to firstname.lastname@example.org, and I reply to that email, the from address will be "email@example.com" instead of my Gmail address. All of the other Gmail clients I've tried (Evomail, Mail.app, etc.) reply from my Gmail address by default no matter what address the email was sent to. They allow me to select the "firstname.lastname@example.org" address manually, but it's not selected by default. I can't remember whether Mailbox does this, but I can't use Mailbox anyhow because it doesn't allow me to use my own Gmail labels. That's a dealbreaker. Any ideas?
