Your Gmail signature is probably missing entirely. Or it features an old headshot and a quote nobody asked for.

Neither helps you.

Your email signature appears at the bottom of every message. It works as your digital business card and final impression. Most people treat it like an afterthought.

Let's fix that.

Why Your Gmail Signature Matters

According to The Radicati Group, worldwide email users will hit nearly 5 billion by 2028. Business email communications remain central to daily work.

A professional Gmail signature tells people who you are, how to reach you, and why they should pay attention. Everything else is noise.

Note: Gmail signatures differ from handwritten signatures used to sign documents. Those carry legally binding weight. Your email signature identifies you and provides contact details.

How to Add a Signature in Gmail (Desktop)

Here's how to add a signature in Gmail. The whole process takes about two minutes.

1. Open Gmail and click the gear icon in the top right corner
2. Select "See all settings"
3. Scroll to the "Signature" section
4. Click create new and name your signature
5. Type or paste your signature in the editor
6. Choose defaults for new emails versus replies
7. Scroll to the bottom of the page and click "Save Changes"

Your gmail signature now appears on every email you send. No need for a free email signature generator when Gmail handles it natively.

Gmail Signature Settings You Should Know

Gmail buries useful options in the signature settings area.

Signature defaults: Assign specific signatures to specific email addresses. Business email gets the professional signature. Personal email gets something simpler.

Default signature selection: Choose which signature appears automatically for new messages and which one shows on replies.

Insert before quoted text: Check this box. Otherwise your signature lands at the bottom of long email chains where nobody sees it.

Rich text formatting: The toolbar lets you add a link, change fonts, and adjust formatting. Use it sparingly. Heavy formatting breaks across email clients.

How to Add a Signature in Gmail on Mobile

Mobile signatures work differently on mobile devices.

iPhone and iPad:

1. Open the Gmail app
2. Tap the menu icon (three lines)
3. Tap Settings, then select your account
4. Tap "Signature settings" and toggle on
5. Type your mobile signature

Android:

1. Open the Gmail app
2. Tap the menu icon, then Settings
3. Choose your account
4. Tap "Mobile signature"
5. Enter your signature

Your mobile signature stays separate from desktop and won't sync automatically. Many professionals use a shorter mobile signature since brief sign-offs fit the medium better.

These examples skip the fluff: no quotes, no seventeen social links, no massive logos. A professional gmail signature ensures brand consistency and keeps things simple.

Creating an Email Signature for Multiple Contexts

Gmail lets you create multiple signatures.

Build separate signatures for clients, internal teams, and vendor relationships. Each audience needs different information.

Create a "first contact" signature with full context and a stripped-down "reply" version. This keeps your email communications consistent while adapting to different situations and ensures consistency across all your messages.

Set your default signature, then override when needed.

Gmail Signature with Image: When It Works

Adding a gmail signature with image sounds smart. It can work well, or it can backfire.

When images work:

• Small company logos (under 100 pixels wide)
• Compressed headshots that add a personal touch
• Simple icons linking to social profiles

When images fail:

• Large banners dominating the signature
• Uncompressed image files bloating email size
• Images serving no clear purpose

To add an image, click the image icon in the signature editor. Upload your image file or paste a URL, then resize. You can also add a call to action like "Book a meeting" with a linked button.

Test across platforms. What looks perfect in Gmail might break in Outlook.

Common Gmail Signature Mistakes

The novel: Signature longer than your email? Cut it to four to six lines.

The quote collection: "Be the change" tells recipients nothing useful. Remove it.

The dead links: Remove social handles you haven't touched in years.

The formatting explosion: Ten fonts and five colors looks chaotic, not professional.

The outdated info: Old job title? Update it.

Beyond the Signature: What Matters Most

Email signatures are the footnote, not the story.

Your email content matters far more than what appears at the bottom. A perfect signature won't save a poorly written message.

Writing clear, accurate emails takes time. You pull information from your CRM, reference past conversations, and check project status across tools.

Revo handles this problem. Revo connects to your business context, meetings, Slack, project tools, and drafts replies based on real information. Your emails become accurate because they draw from facts across your workday.

Your signature introduces you. Your email content moves work forward.

The Bottom Line

Learning how to add a signature in gmail takes two minutes. Creating an email signature worth adding takes more thought.

Keep it short. Make it useful. Test across email clients. Update when things change.

Frequently Asked Questions

How do I add a signature in Gmail with a clickable link?

Highlight the text, click the chain icon in the signature editor, paste your URL, and click OK. Test by sending yourself an email first.

Why does my Gmail signature look different when others receive it?

Email clients render HTML differently. Heavy formatting with multiple fonts or large images breaks most often. Stick to simple formatting and web-safe fonts like Arial.

Can I have different signatures for different Gmail accounts?

Yes. Go to Settings, scroll to Signature, and use the dropdown to select which address you're configuring. Each account can have its own default signature.

What's the ideal length for a professional Gmail signature?

Four to six lines: name, title, company, and one or two contact methods. Boomerang research shows that shorter messages get better response rates.

Should I include my phone number in my Gmail signature?

Include it if you prefer calls. Sales and client-facing roles benefit from easy phone access. For email-preferred roles, leaving it out reduces unwanted calls.
