How to add a signature in Gmail

Short answer
On desktop: gear icon, See all settings, General, scroll to Signature, Create new, paste, set defaults, and Save Changes. The Gmail mobile app uses a separate plain-text signature per account.
Which version do you use?

Works the same in Chrome, Safari, Edge and Firefox.

  1. 1

    Open Settings

    In Gmail, click the gear icon (top-right) and choose See all settings.
  2. 2

    Scroll to the Signature section

    Stay on the General tab and scroll about two-thirds of the way down until you see Signature.
  3. 3

    Create a new signature

    Click + Create new, name it (e.g. "Main"), and click Create. A rich-text editor appears.
  4. 4

    Paste your signature into the box

    Click into the editor and paste with Cmd+V or Ctrl+V. Don't have one yet? Pick a free signature from Wren's gallery. Open the free generator.
  5. 5

    Set defaults for new mail and replies

    Under Signature defaults, pick your signature in the FOR NEW EMAILS USE and ON REPLY/FORWARD USE dropdowns.
  6. 6

    Save Changes

    Scroll to the bottom and click Save Changes. Send yourself a test to verify.

Menu names occasionally move — look for Settings → Signature.

Multiple signatures and send-as aliases

Gmail supports multiple signatures per account and can assign a signature to each send-as alias. The address dropdown appears next to each signature in the settings.

Different signature on replies

Create a shorter second signature (name, title, one link) and pick it in the ON REPLY/FORWARD USE dropdown, or leave it empty for no signature on replies at all.

Google Workspace: admins can set defaults

Admins can push signatures via App Script or a paid tool. Neither overrides what the user set locally unless an SMTP-level footer is used, which can look duplicated.

Formatting keeps breaking after paste

Paste into a fresh signature slot rather than editing an existing one. If a link picks up an unwanted underline or color, select it and clear formatting, then repaste that line from Wren.

Common questions

›Where's the signature setting in Gmail?
Gear icon then See all settings, General tab, scroll to Signature. Save Changes at the bottom of the page.
›Why doesn't my desktop signature show on my phone?
Gmail treats mobile as a separate device with its own plain-text signature. Set it in the Gmail app under Settings for that account.
›Images don't show for the recipient. Why?
The image needs a public HTTPS URL Gmail can proxy. Signatures generated in Wren host every asset for you.
›Can I have one signature per Google account?
Yes. Each Gmail account has its own Signature settings; set them independently.
›How do I change my Gmail signature later?
Same place: gear then See all settings, General, Signature. Edit and Save Changes.
