Use Rich Text Formatting in Your iOS Mail Signature

Email signatures save time and add information automatically

If you send a lot of emails in a day, having a preset signature can save you time. When you send an email from an account with a signature, the signature appears at the end of every email automatically. You set up basic email signatures in the Settings app on your iPhone or another iOS device.

In Settings, you can format the signature to contain boldface, italics, and underlines—a sparse selection of rich text features. You could edit the basic signature at the bottom of every email you send out, one at a time, if you are looking for a more feature-rich signature, but that defeats the purpose of setting one up in the first place. Fortunately, there's a workaround that you can use to jazz up your signature when you set it up.

Information in this article applies to iOS devices running iOS 12, iOS 11, or iOS 10.

Why Use Formatting in Your Signature?

The text of your email signature may be as short as your name. However, it could also contain your title, contact information, company name, or a favorite quotation.

Perhaps using bold letters would increase the signature's utility. Italic script might heighten interest. An underline in the right place could draw the recipient's eye. Using all these basics in one signature might be a bit much, but the judicious application of rich text features can be beneficial.

For signatures used in iOS Mail on iPhone, iPod Touch, and iPad, adding that kind of formatting is easy.

You can opt to use the same signature for all your email accounts or set up a different one for each account.

  5. Double-tap any word you want to format. Use the text highlighting handles to select more or fewer words or characters.

  6. Tap B/U in the context menu that appears above the chosen word. If you don't see it, tap the arrow at the end of the context menu to reveal more options.​

  7. For bold text, tap Bold. For italicized text, tap Italics. For underlined text, tap Underline.

  8. Repeat the process of selecting parts of the signature and then formatting them. Exit the screen to save the changes.

Beyond the Basics

If you are looking for a signature with a little more flair—or at least some font choices—you need to go to a different iOS app: Pages. The Pages app is a free download from the App Store. You can use its advanced formatting capabilities to add color, change font size and type, and add links. Then, a quick copy sends it to the Signature settings. Here's how:

  1. Tap the Pages app and open a blank page.

  2. Type the content of the signature.

  3. Select a word or line of text and click the Paintbrush at the top of the screen to bring up formatting options. Select a color, size, font, or one of the many other available options.

  4. Select another word or line of text and repeat the formatting process.

  5. When you are finished formatting, copy the signature by pressing on it and tapping Select All, followed by Copy.

  6. Leave Pages and go to Settings > Mail > Signature. Paste the copied signature into the desired account field by tapping the area and selecting Paste.
