How to install your email signature in the Gmail app
The Gmail app's mobile signature setting only accepts plain text: no logo, no colors, no clickable buttons. This is a Gmail limitation, not something a signature tool can work around inside the app. Here is where that setting lives, what to expect, and how to still send a branded signature from your phone.

Open the generatorUnderstand the limit first
Settings, your account, Mobile Signature in the Gmail app takes plain text only. Any signature pasted there loses its logo, color, and formatting, links appear as plain web addresses.
Copy your signature
Open your personal signature link and tap Copy signature. This copies a rich version and a plain-text fallback together.
Open the Gmail app's mobile signature setting
Tap your profile photo, then Settings, then your account, then Mobile Signature.
Paste into the field
Tap into the box and paste. Because the field only accepts plain text, it automatically uses the plain-text fallback: your name, title, and contact details show, without the visual branding.
For a fully branded signature, use the browser instead
Open Gmail in your phone's browser and request the desktop site, then use the same signature settings as Gmail on the web to get the full HTML version applied to your account.
Common questions
No. The Gmail app's Mobile Signature field is plain text only. This is a limit of the app itself, not something a signature tool can change.
That is a reasonable choice if your team sends most email from desktop. Leaving it blank means no signature appears on replies sent from the app, which some teams prefer over a stripped-down plain-text version.
Yes. Most email apps auto-detect plain web addresses and email addresses and make them tappable, even without the button styling from the full signature.
