Sign email attachment on Mac using iPhone

There are plenty of times when we need to sign and return documents via email. Contracts, agreements, acknowledgments, and the like are often sent electronically these days. And while you can create a signature in Preview on Mac, you might not be able to.

Maybe you have an iMac without a trackpad, or you simply can’t make your signature look the way you want it with a mouse. But if you use an Apple Pencil with your iPad or have an easier time signing with your finger on your iPhone, you can use one of those devices instead.

Get your attachment ready

The first step in signing an attachment you’re sending is to put it in your email. You can do this in a few ways:

  • Drag and drop the document from its location into the email.
  • Click the Attach button (paperclip) in the Mail toolbar.
  • Select File > Attach Files from the menu bar.

You can compose your email before or after signing your document per your preference. So now let’s get to signing that document.
