Sign PDFs Instantly Right in the IPhone Email App
We’ve talked about signing documents from your phone before , but one of the lesser known features of iOS 9 was integrating this directly into the Mail app.
IOS 9 introduces “markup” for Mail, which allows you to draw images and add notes. Let’s be honest, this is a feature that most of us probably never use. This menu also has a signature section where you can easily sign the PDF and send it. Just open the PDF in Mail, tap the toolbar icon, then tap the signature icon in the bottom right corner. Use your finger to sign it and you can mail it to the sender. It’s not a feature that most of us might need very often, but it’s nice to know it’s there.
