Apple Mail E-Mail Signatures on iOS and iPadOS
If you’ve created e-mail signatures for Apple Mail in iOS/iPadOS, you are probably aware that signatures for Apple Mail in iOS/iPadOS are very basic. They are created using a default font, font size and font color. There are few options to customize your signature (ex: you can’t change font size or font color).
And, even if you create a well formatted signature in another application then copy and paste the signature into the Apple Mail e-mail signature field for the respective mail account in iOS/iPadOS, the signature text will revert to the default font, font size and font color.
That said, there is a workaround albeit not an intuitive one and still quite limited at best (you’ll be able to change the font size and font color)!
Here’s what you’ll need to do:
Create your formatted e-mail signature in your choice of application (again, you may change font size/font color)
Copy the formatted e-mail signature
Paste the formatted e-mail signature into the signature field of the respective Apple Mail account (Settings | Mail | Signature). By default, the formatted e-mail signature will revert to the basic default
Use the three-finger swipe in the signature field to undo the changes to the attributes
You should see a message pop-up which says, “Undo Change Attributes”
Select Undo
The basic default signature text should revert to the formatted e-mail signature text that you originally pasted into the signature field
If you want to truly stylize your e-mail signature with custom fonts and embedded images (HTML e-mail signature), you’ll need to stick with supported client e-mail applications for the desktop (ex: Outlook for Windows/Mac). Most client e-mail applications for mobile do not currently support the creation of HTML e-mail signatures (this includes Outlook for iOS/iPadOS).
Lastly, keep in mind that even if you can see the formatted e-mail signature, how the recipient will see it will depend on the client e-mail application and device they use and how they are setup. The same applies to HTML e-mail signatures.
