TalkMail Newsletter - Can we have a web version please?
Sorry if this comes across as a First World Problem (I.e. Not really a problem) but it's two in the morning, I'm in a hotel, awake, trying to read TalkMail on my iPad and constantly having to switch between the mail app and Safari to read each thread which is a real PITA.
My suggestion would be for you to not only send the email but as normal but also to offer an online version via a link in the email. That way it's easier for iPad and other tablet or mobile users to switch between pages/tabs in the same application.
