Adding a signature in Gmail helps you close emails with a professional identity that includes name, title, contact details, and branding. Whether you use the Gmail desktop web interface or the Gmail mobile app, the steps are streamlined once you know where to look.
This guide walks through how to add or edit a signature on desktop and mobile, compare settings at a glance, adjust formatting, and avoid common pitfalls. Follow the steps below to make sure every message you send ends with a polished, consistent signature.
| Platform | Where to Open Settings | Signature Visibility | Quick Action |
|---|---|---|---|
| Gmail Desktop | Settings gear → See all settings → General → Signature | Default on all new messages; can be disabled per compose | Toggle on/off before sending |
| Gmail iOS App | Menu → Settings → Select account → Signature | Applies to messages composed in the app | Edit text and formatting inline |
| Gmail Android App | Menu → Settings → Account → Signature | Syncs with account-level settings where available | Use rich editor for links and styling |
| Shared/Workspace Accounts | Admin console may enforce organization signature | User signature can be overridden by admin policy | Check with IT if changes do not save |
Compose with a Signature on Desktop
On desktop, Gmail keeps signature settings in General under Settings. This is the central place where you define text, links, and basic HTML-like formatting for every new message and reply.
Open Settings by clicking the gear icon, then choose See all settings to expand full options. Navigate to the General tab, locate the Signature section, and either create a new signature or edit an existing one. You can switch between plain text and a richer editor that supports bold, italics, and hyperlink insertion.
Desktop Signature Placement Options
Gmail lets you choose where the signature appears to avoid cutting off quoted text. Below the typed message is the default, which keeps your closing lines prominent. Above quoted text places your signature after your own text but before any pasted replies, helping readers see who is writing.
Choosing the top option, before quoted text, is rarely ideal for everyday replies because it can obscure context. For teams that rely on consistent branding, selecting below the typed message is usually the most reliable behavior across long conversation threads.
Configure Signature on Gmail Mobile
The Gmail mobile apps provide a simplified path to signature settings, but the available controls vary between iOS and Android. Keeping your profile consistent across devices ensures that recipients recognize your messages regardless of platform.
On iOS, open the menu, tap Settings, select your account, and then choose Signature to type and format. On Android, go to Menu → Settings, pick your account, and adjust the same fields. Both interfaces support basic formatting, so you can include links and emphasis without switching to desktop.
Signature Formatting and Styling Tips
Gmail does not offer deep CSS control, but you can still make your signature readable and professional. Keep line breaks clean by avoiding multiple empty paragraphs, and use dashes or vertical bars sparingly to separate sections without creating visual clutter.
Include essential contact fields such as full name, job title, company, phone, and direct email. Add links to profiles or websites using the chain icon in the editor, and test how the rendered signature appears on both light and dark themes if your organization uses custom colors.
Troubleshooting and Best Practices
If your signature disappears on some messages, check whether admin policies are enforcing a template or if the account has multiple profiles enabled. It is also worth confirming that you saved changes in Settings and restarted the app or browser to clear cached data.
- Define a single master signature for consistency across desktop and mobile.
- Keep lines short to avoid awkward wrapping on mobile screens.
- Use plain text links instead of tiny logos that may not load.
- Test replies to ensure quoted content does bury your closing block.
- Verify appearance in both light and dark modes if supported.

FAQ
Reader questions
Why does my signature show on new messages but not on replies?
Check the placement setting; if it is set to above quoted text, your signature may be hidden behind long reply chains. Switch to below the typed message so it appears after your text and before any pasted responses.
Can I have different signatures for work and personal accounts on the same device?
Yes, sign into each account separately and configure a distinct signature under Settings for each one. When you compose while logged into a specific account, Gmail applies that account’s signature automatically.
My images in the signature are not loading on mobile; how can I fix it?
Host images on a reliable external server and use absolute URLs, and avoid embedding large attachments. Also confirm that external images are not blocked by Gmail’s image load setting, which can prevent photos from showing on mobile.
Will changing the signature affect old emails or threads already sent?
No, signature updates only apply to new messages and future replies. Sent conversations remain unchanged, so you do not need to worry about altering historical correspondence when you adjust the template.
