How to Add Formatting or HTML Signatures
iPhones don’t let you format text directly inside the Signature box.
However, you can paste a formatted signature if you created it elsewhere.

Outlook web

A signature generator

Any HTML editor

How to Add Images or Logos to Your iPhone 13 Email Signature
iPhones do not support inserting inline images (logos) directly into the signature field.
However, you can use:
-
Linked logos (hyperlinked text instead of graphic images)
-
Emoji icons for simple decoration
For example:

Why Your iPhone 13 Signature May Not Be Working
If your signature isn’t appearing in emails, check the following:
1. Ensure Mail is Using the Correct Account
Some apps override signatures if they use Gmail/Outlook inside their native app.
2. Make Sure You’re Using the iOS Mail App
The signature settings only apply to Apple’s built-in Mail app.
3. If Using Multiple Accounts, Check “Per Account”
You may have edited the wrong account.
4. Restart Your iPhone
Sometimes cached settings need a refresh.
