Setting up your email signature on your iPhone or iPad

A signature is text added automatically to the bottom of every email you send, such as your name, job title, or company details. Here is how to set one up in the Mail app on your iPhone or iPad.

These steps are for iOS and iPadOS 26. Earlier versions are very similar, though some menu names may differ slightly.

How to set up your email signature

1. Open the Settings app.
2. Scroll down and tap Apps, then tap Mail.
3. Scroll down and tap Signature.
4. Type the signature you want added to the end of your outgoing messages.
5. Tap the back arrow to return to the previous screen. Your signature is saved automatically.

There is no separate save button - leaving the screen keeps your changes.

Testing your signature

Open the Mail app and start composing a new message. Your signature should appear automatically at the bottom. If you want to adjust the wording, go back to Settings and tap through to the Signature screen again.

A note on formatting, logos and images

The Signature box is designed for plain text, and for a mobile signature plain text is genuinely the best choice. It displays reliably in every email program your recipients might use, stays small, and looks clean on a phone screen. A name, title, company, phone number and web address is all most signatures need.

It is possible to create a formatted signature with bold text, colours or a logo by composing it elsewhere, copying the finished result, and pasting it into the Signature box, which keeps the formatting. We would suggest doing this only if you have a specific need, because rich signatures on mobile are fragile - spacing and formatting can shift between email programs, and the result often looks less tidy than clean text.

If you do want a logo or image in your signature, one point is worth understanding, because it is the most common cause of signatures that look broken to recipients:

• Avoid embedding the image itself. When you paste an actual image into the signature, a copy is attached to every email you send. Recipients often see it as a separate file attachment or a broken-image placeholder rather than a neat logo, it makes every message larger, and it can increase the chance of your mail being treated as spam.
• Reference a hosted image instead. A signature that points to an image stored on a website - rather than containing the image itself - does not attach anything to your emails and stays lightweight. The trade-off is that many email programs block remote images until the recipient chooses to load them, so the logo may not appear straight away for everyone. This is normal and applies to all senders, not something specific to your account.

In short: for a signature that always displays correctly, keep it to text. If you need a logo, host it and reference it rather than embedding it, and accept that it will not show for every recipient. For a polished branded signature that you have full control over, a desktop email program is a better place to build it than a phone.
