An email signature shows up at the bottom of outgoing emails. It might include a name and title, a funny quote, or helpful information such as a website URL or phone number. Email signatures are set up on the iPhone and iPad in the Settings app. The default signature line for the iPhone is "Sent from my iPhone," but you can change this signature to anything you want (or use none at all). You can even generate an email signature that differs for each of your connected email accounts.

How to Make a Basic iOS Email Signature

Here's how to set up a basic email signature that automatically shows up at the end of each of your outgoing emails on your iPhone or iPad:

  1. From the iPhone or iPad home screen, open the Settings app.

  2. Scroll down and tap Mail.

    If you don't see this option, the most recent version of iOS isn't installed on your device. Instead, select Mail, Contacts, Calendars.

  3. In the Composing section, tap Signature.

  4. Type the desired email signature in the space provided, or remove all of the text to delete the email signature.

    If you have more than one email address set up in Mail, and you want to use the same email signature for all addresses, tap All Accounts. Or, choose Per Account to specify a different email signature for each account.

  5. To apply formatting, double-tap the signature and use the handles to select the portion of the signature that you want to format.

    If you don't see the menu, tap the right-pointing arrow on the menu bar. It may be called BIU.

  7. Tap either Bold, Italic, or Underline.

    To apply a different formatting style to another part of the signature, tap outside the text and repeat the process.

  8. Tap the arrow in the upper-left corner of the Signature screen to save the changes and return to the Mail screen.

Add Images and Other Formatting to a Signature

By default, you can't change the color, font, or font size of an email signature. The iOS Mail app signature settings offer only basic rich text features. Even if you copy and paste a formatted feature from elsewhere into the Mail signature settings, most of the rich text formatting is removed. However, there's a trick to make these formatting details, including images, appear in the signature when you paste it.

  1. From a computer, log in to the email account you want to use the signature from, and create the email signature exactly how you want it to look on your iOS device.

  2. Compose a new message so that the signature is used, save the email as a draft, then open it from your iPhone or iPad.

  3. Tap and hold an empty space in the message, choose either Select or Select All, then make changes to the highlighted content.

  4. Select Copy.

  5. Select Cancel on the draft message, then open the Signature area in the Settings app.

  6. Tap and hold in the signature box, then select Paste. The signature looks similar to, but not exactly like, the one you created.

Tips for Composing an Email Signature

Although the default signature-formatting options on an iOS device don't provide much variety, you can still generate an effective signature by following a few guidelines.

  • Keep it short. Limit your signature to no more than five lines of text. If you think you can't make your information fit, use pipes (|) or colons (:) to separate text sections.
  • A business signature should include your name, title, company name, a link to the company website, and a business phone number. If available, add a link to a recent article or post about you or your company.
  • You don't need to include your email address in your email signature because it's at the top of the email. 
  • For a personal email account, include links to your social profiles on Twitter, Facebook, and LinkedIn.
  • Short, inspiring quotes often appear at the end of email signatures. These are more appropriate for personal than business signatures.
  • Leave out any legal disclaimers unless your company requires you to include one.
  • Test your formatted signature with several email clients to make sure it looks the way you want.
