Quick step-by-step summary (click to expand)

1. Open Gmail settings. Click the gear icon at the top right of Gmail on desktop, then click “See all settings”.
2. Scroll to the Signature section. Under the General tab, find the Signature panel.
3. Create your first signature. Click “Create new”, give it a name, and enter the signature text.
4. Add more signatures. Click “Create new” again for each additional signature. Give each a clear name like “Work” or “Personal”.
5. Set your defaults. Under “Signature defaults”, pick which signature Gmail uses for new emails and for replies.
6. Save changes. Scroll to the bottom of the settings page and click “Save Changes”.
7. Switch signatures per email. When composing, click the pen icon in the toolbar and choose the signature you want for that message.

Why bother with multiple signatures

One signature works if you use Gmail for one purpose. But most people use their inbox for multiple things: a full-title corporate signature for external clients, a shorter signature for internal team replies, a personal signature for friends, and maybe a project-specific signature with a phone number for on-call rotations. Switching manually is error-prone. Gmail’s multiple-signature feature lets you save each one and switch with two clicks.

Create multiple signatures on Gmail Web

The full editor is only on the web version. Set your signatures here first, then they sync to mobile automatically.

1. Open mail.google.com on desktop.
2. Click the gear icon at the top right, then click “See all settings”.
3. Under the General tab, scroll down to the Signature section.
4. Click “Create new”. A dialog asks for a signature name. Type something clear like “Work full”, “Work short”, or “Personal”.
5. Type your signature in the editor. You can format it (bold, italic, colors), add a hyperlink, or insert an image (Google Drive image, uploaded image, or a URL).
6. Click “Create new” again to add another. Repeat for as many signatures as you need. Gmail allows up to 10,000 characters per signature and no hard limit on how many signatures you save.
7. Scroll to the bottom and click “Save Changes”.

Common signature elements that work well: full name, job title, company name, direct phone (if you want it public), and one link. Keep it under 5 lines to look professional.

Set default signatures for new emails and replies

Under the Signature section, right below your saved signatures, you will see “Signature defaults”. Two dropdown menus:

• FOR NEW EMAILS USE: Pick the signature Gmail applies when you compose a new message.
• ON REPLY/FORWARD USE: Pick a different signature for replies. Many people use a shorter one here to avoid signature stacking in long threads.

Set both, then click “Save Changes” at the bottom of the page.

Switch signatures per email

Sometimes you want a different signature for a specific email regardless of the default. When composing:

1. Click the pen icon in the compose window toolbar (at the bottom of the compose box, labeled “Insert signature”).
2. Pick the signature you want from the dropdown. It replaces the current one in the message.
3. Send as usual. Your default stays unchanged for future emails.

This is the fastest way to switch tone mid-conversation, for example switching from “Work full” to “Work short” once you have already introduced yourself.

Manage signatures on the Gmail Android app

The Android app has a simpler signature editor. It does not support multiple signatures per account, but any signatures you set on the web will sync and be selectable when composing.

1. Open the Gmail app on Android.
2. Tap the menu icon (three lines) at the top left, then tap “Settings”.
3. Tap your account name.
4. Tap “Mobile Signature” for a mobile-only signature, or leave blank to use the web signature.
5. When composing on Android, tap the compose menu and pick the signature from the list synced from the web.

Manage signatures on the Gmail iPhone app

The iPhone app works similarly. Multi-signature switching from the web syncs down. To set a mobile-specific signature:

1. Open the Gmail app on iPhone.
2. Tap the menu icon at the top left, then scroll down and tap “Settings”.
3. Tap your account.
4. Tap “Signature settings”, then toggle “Mobile Signature” on and type your signature.
5. Tap the back arrow to save. When composing, tap the compose menu to pick from your saved signatures.

Troubleshooting: signatures not showing up

• Signature is blank in the recipient’s email. Some email clients block inline images. If your signature uses an image, add a text-only fallback line.
• Signature appears twice. This happens when both the web default and a mobile signature are set. Turn off the mobile signature or set it identical to your web signature.
• Signature does not save on mobile. Force-quit the Gmail app and reopen. If that fails, sign out and back in on the mobile app.
• Switching does not work in Gmail on Android. Multi-signature switching requires the latest Gmail app version. Update from Google Play Store.
• Corporate account has grayed-out options. Your Google Workspace admin may have locked signature settings. Ask your IT admin to unlock the Signature panel.

Best practices for professional signatures

Keep signatures short. Recipients ignore anything longer than 5 lines. Use plain text or minimal formatting so the signature renders correctly in any email client (Outlook, Apple Mail, Thunderbird all display signatures differently).

Do not include large images or GIFs. They inflate email size and trigger spam filters. If you need a logo, upload it to Google Drive first and link to it, or use a small (under 20 KB) hosted image.

Do not include your full mailing address unless you legally need to (GDPR, some finance industries). Address information in a signature can be scraped by data brokers.
