Add a signature in the Mail app settings

Open Settings on your iPhone, then scroll down and tap Mail. Scroll to the bottom of the Mail settings screen and tap Signature. You'll see options to set different signatures for each email account, or one signature for all accounts.

If you have multiple email accounts on your iPhone, you can tap Per Account to create a different signature for each one. If you want the same signature across all accounts, tap All Accounts and type your signature once. The text you enter here will appear at the bottom of every email you send from the Mail app.

Your signature can include your name, phone number, job title, website, or any other text you want to appear automatically. There's no character limit, though very long signatures can make emails harder to read on small screens.

Key Takeaways

  • Go to Settings > Mail > Signature to add or edit your email signature on iPhone.
  • Choose Per Account if you want different signatures for different email addresses, or All Accounts for one signature everywhere.
  • Your signature appears automatically at the bottom of every email you send through the Mail app.
  • You can change or remove your signature at any time by returning to the same settings screen.
  • Third-party email apps like Gmail or Outlook have their own signature settings separate from the Mail app.

What happens if you use Gmail or Outlook instead

If you use the Gmail app or Microsoft Outlook app instead of Apple's Mail app, the signature setting is not in your iPhone's main Settings. Each app manages signatures inside its own settings.

In the Gmail app, tap your profile picture in the top right, then Manage your Google Account > Personal info > About me. Scroll down to Signature and add your text there. In the Outlook app, tap the menu icon (three horizontal lines) in the bottom right, then Settings > select your email account > Signature. Both apps will add your signature to outgoing emails automatically.

Edit or remove your signature later

To change your signature, go back to Settings > Mail > Signature and edit the text. To remove it entirely, delete all the text in the signature field and leave it blank. The next email you send will have no signature.

If you've set up per-account signatures and want to change just one, tap the account name under the signature field, make your edit, and tap back. Your other signatures stay the same.

Why your signature might not appear

If you've added a signature but it's not showing up on your emails, check that you're using the Mail app, not a third-party email app. Signatures set in Settings only work with Apple's Mail app. If you're using Gmail, Outlook, Yahoo Mail, or another app, you need to set the signature inside that app instead.

Also check that you didn't accidentally turn off the signature setting. Go back to Settings > Mail > Signature and make sure the field isn't empty. If you're sending emails from a different device or webmail, those won't include your iPhone signature — you'd need to set a signature on each device or account separately.

Signature formatting and what you can include

The Mail app signature field accepts plain text only — you cannot add bold, italics, colors, or images directly in the signature settings. If you want a fancier signature with formatting, you can type it out in plain text and it will still appear in your emails, but the formatting won't carry over.

Common things to include in a signature are your full name, phone number, job title, company name, website URL, or a short professional tagline. Keep it brief so it doesn't take up too much space in your emails, especially on mobile where screen space is limited.

Frequently Asked Questions

Can I have different signatures for different email accounts?

Yes. In Settings > Mail > Signature, tap Per Account instead of All Accounts. Then tap each account name and enter a different signature for each one. This is useful if you have a work email and a personal email with different contact information.

Will my signature appear on emails I forward or reply to?

Your signature appears on new emails you compose. When you reply to or forward an existing email, the signature is added below your reply text. Some email threads can get long with multiple signatures stacked, so keep yours concise.

What if I don't want a signature on one specific email?

The Mail app doesn't have a built-in way to skip the signature on a single email. You would need to delete it manually after composing the email but before sending. Tap and hold the signature text, select it, and delete it before you hit send.

Does my signature work if I send email from my iPhone using a computer's email account?

No. Your iPhone signature only works for emails sent from the Mail app on your iPhone. If you access your email through a web browser or on a computer, you need to set up a signature in that email account's settings separately. Each device and email client manages signatures independently.

Can I add an image or logo to my signature?

Not through the Mail app settings. The signature field only accepts text. If you need an image in your signature, you would need to use a third-party email app that supports rich formatting, or add the image manually to each email before sending.
