Add a signature in Gmail's mobile app in three steps

Open Gmail on your phone, tap the menu icon (three horizontal lines) in the top left, scroll down and tap Settings, then find your email account and tap it. Tap Signature, then Add signature. Type or paste the text you want to appear at the end of every email you send from that account — your name, phone number, job title, or any closing line — then tap OK or Save depending on your phone's operating system.

The signature will now appear automatically on every new email you compose. If you have multiple email accounts in Gmail, you can set a different signature for each one by repeating these steps for each account.

Key Takeaways

  • Gmail's mobile app stores signature settings in the account-specific settings menu, not in the general app settings.
  • You can set a unique signature for each email account you have added to Gmail on your phone.
  • The signature appears on new emails you write but not on replies or forwarded messages unless you manually add it.
  • If you change your signature later, the new version will appear on all future emails, but old emails you already sent will not change.

Where to find the signature setting on Android

On an Android phone, open the Gmail app and tap the three-line menu in the top left corner. Scroll down past your inbox folders until you see Settings near the bottom of the menu. Tap Settings, then tap the email account you want to add a signature to — if you only have one account, it will show your email address.

Once you are in that account's settings, scroll down until you see Signature. Tap it, then tap Add signature. Type your signature text, then tap the back arrow or the checkmark to save it. The signature is now active for that account.

Where to find the signature setting on iPhone

On an iPhone, open Gmail and tap the menu icon (three horizontal lines) in the top left. Scroll to the bottom and tap Settings. Tap the email account you want to add a signature to. Scroll down and tap Signature.

Tap Add signature, type your signature text into the box that appears, then tap Save. The signature will now appear on all new emails from that account. If you have multiple accounts, repeat this process for each one.

What text works best in a signature

Keep your signature short — most people use just their name and one or two contact details. Common signatures include your full name and phone number, your name and job title, or your name with a company website. Avoid very long signatures or multiple lines of graphics, because they take up space on small phone screens and can look cluttered when someone reads your email on their phone.

If you use Gmail for both work and personal email, consider different signatures for each account. Your work account might include your job title and company phone number, while your personal account might just be your name. This keeps professional and personal emails clearly separated.

Signatures on replies and forwarded emails

When you reply to an email or forward one, Gmail does not automatically add your signature. If you want your signature on a reply, you have to type it manually or copy and paste it into the message. This is intentional — most people do not want their full signature appearing on every line of a long email thread.

If you always want your signature on replies, you can turn this on in the full Gmail website settings (not in the mobile app). Log into Gmail on a computer, go to Settings > General, scroll down to Signature, and check the box that says Insert signature before quoted text in replies and in forwarded messages. This setting will then apply to your mobile app as well.

Changing or removing your signature later

To change your signature, follow the same steps you used to add it: go to Settings > your account > Signature. Tap the signature text to edit it, make your changes, and save. The new signature will appear on all emails you send from that point forward.

To remove your signature entirely, go back to the signature settings and delete all the text, leaving the box empty. Tap Save or the back arrow. Your emails will no longer have a signature at the end.

Frequently Asked Questions

Can I have different signatures for different email accounts?

Yes. Each account you add to Gmail can have its own signature. Go to Settings, tap each account one at a time, and set a unique signature for each. When you compose an email, Gmail will use the signature for whichever account you are sending from.

Why doesn't my signature appear on replies?

Gmail's mobile app does not add signatures to replies by default. You can turn this on in the full website version of Gmail under Settings > General, then check the box for inserting signatures in replies. After you do this on the website, the setting will apply to your mobile app too.

Can I use special characters or emojis in my signature?

Yes, you can type or paste any character your phone's keyboard supports, including emojis. Keep in mind that some older email clients may not display special characters correctly, so stick to standard letters, numbers, and punctuation if you are emailing people with older email systems.

What happens to old emails if I change my signature?

Emails you already sent will not change. Only new emails you compose from that point forward will use the new signature. The old emails will still show whatever signature (or no signature) they had when you sent them.
