How to add a signature in Gmail

Gmail keeps its full signature editor on the desktop settings page. The mobile apps can either use that desktop signature or replace it with a separate text signature. These steps cover both paths, including the defaults that determine whether the signature actually appears.

Use more than one Gmail signature

Gmail can keep several signatures. Create each one in the same Signature section, then use the pen icon in a compose window when you want to switch for one message. The default dropdowns decide which one is added automatically.

Different signatures for different sending addresses

If you use Gmail’s Send mail as feature, select the sending address from the dropdown above the signature editor before creating or editing its signature. If the dropdown is missing, check that the address exists under Accounts and Import.

Gmail signatures on Android, iPhone and iPad

A mobile signature belongs to the Gmail app and the selected Google Account. If you leave it disabled, new messages can use the signature configured on your computer. Enable it only when you want a separate, simpler signature for messages sent from the app.

Android

Open Menu, Settings, choose the Google Account, then select Mobile signature. Enter the text and tap OK.

iPhone and iPad

Open Menu, Settings, then Signature settings under Compose and Reply. Turn on Mobile Signature, edit it, then go back to save.

Why a Gmail signature is missing or looks wrong

It never appears automatically: Choose the signature in both default dropdowns. Creating it does not make it the default.
It appears on new emails but not replies: New messages and replies or forwards have separate defaults. Set the second dropdown too.
The wrong address gets the signature: Select the correct Send mail as address above the editor and configure its own signature.
An image is missing: Use a publicly accessible HTTPS image and keep it reasonably small. Gmail counts images toward its signature size limit.
Pasting removes the design: Paste normally with Ctrl + V or ⌘ + V. A paste-without-formatting command strips the layout and links.
