How To Change Your Signature in Gmail: Step‑by‑Step Guide

Email signatures in Gmail are those little blocks of text (sometimes with a logo or links) that automatically appear at the bottom of your emails. They can be as simple as your name, or as detailed as your job title, phone number, website, and social profiles.

Knowing how to change your Gmail signature is useful when you switch jobs, update contact details, or just want a cleaner, more professional look.

This guide walks through how it works, the different places signatures show up, and what actually changes based on your device and setup.

What a Gmail Signature Is (And Where It Shows Up)

A Gmail signature is text (and optional formatting) that Gmail automatically adds to your outgoing messages. It can include:

  • Your name and title
  • Phone number or other contact details
  • Website or social links
  • A company logo or small image
  • A short disclaimer or note

There are two slightly different contexts:

  1. Gmail in a web browser (desktop/laptop)
    This is gmail.com in Chrome, Edge, Firefox, Safari, etc.

    • You can create multiple signatures
    • You can choose defaults per account and per “reply/forward”
    • You can switch signatures while composing

  2. Gmail mobile apps (Android / iOS)

    • Has its own mobile signature setting
    • Usually plain text only
    • Works separately from the desktop/web signature

That means changing your signature in one place doesn’t always change it everywhere. The web version and mobile apps can each have their own signature.

How To Change Your Gmail Signature on Desktop (Web)

This is the most full-featured way to manage your signature and the one most people use.

Step 1: Open Gmail Settings

  1. Go to gmail.com and log in.
  2. In the top right, click the gear icon (Settings).
  3. Click See all settings to open the full settings page.

Step 2: Find the Signature Section

  1. Make sure you’re on the General tab.
  2. Scroll down until you see the Signature section.

Here you’ll see:

  • Existing signatures (if any)
  • A Create new button
  • A formatting box for editing

Step 3: Create or Edit a Signature

To create a new signature:

  1. Click Create new.
  2. Type a name for the signature (e.g., “Work”, “Personal”, “Support”).
  3. Click Create.
  4. In the large text box, type and format your signature.

You can use:

  • Bold, italic, underline
  • Text colors and fonts
  • Bullet or numbered lists
  • Links (e.g., to your website or LinkedIn)
  • Images (like a logo)

To edit an existing signature:

  1. Click the name of the signature in the list.
  2. Edit the text in the box as needed.
  3. Adjust formatting, links, or images.

Step 4: Choose When the Signature Is Used

Below the editing box, you’ll see Signature defaults (for each email address you use in that account):

  • For new emails use:
    Choose which signature appears on brand‑new messages.
  • On reply/forward use:
    Choose which signature (if any) appears when you reply to or forward.

You can also tick or untick:

  • Insert signature before quoted text in replies and remove the “--” line that precedes it
    This changes where your signature appears in a reply.

Pick the defaults that match how you normally email. You can still change the signature manually while composing.

Step 5: Save Your Changes

Scroll all the way to the bottom of the page and click Save Changes.

If you close the tab without this step, Gmail will ignore everything you changed in settings.

How To Switch or Remove a Signature While Composing

Even after you set up defaults, you can adjust the signature for a specific message.

  1. Click Compose to start a new email (or open a reply).
  2. At the bottom of the email window, click the pen icon (or three dots > Signature, depending on interface).
  3. Choose:
    • A different existing signature
    • Or No signature

This lets you use:

  • A formal work signature for some messages
  • A shorter or different signature for quick replies
  • No signature at all, when it feels unnecessary

How To Change Your Gmail Signature on Android

The Gmail Android app has its own separate signature setting.

Step 1: Open Gmail App Settings

  1. Open the Gmail app on your Android device.
  2. Tap the three horizontal lines (menu) in the top left.
  3. Scroll down and tap Settings.
  4. Tap the email account you want to edit (if you have more than one).

Step 2: Edit the Mobile Signature

  1. Tap Mobile Signature (or “Signature” depending on version).
  2. Type or change your signature text.
  3. Tap OK or Save.

Notes:

  • This is usually plain text only (no bold, images, or links with formatting).
  • It only affects emails sent from this device in the app.

If you leave it blank or turn it off, the mobile app may use no signature at all, even if the desktop version has one.

How To Change Your Gmail Signature on iPhone or iPad (iOS)

The Gmail app on iOS also has its own setting.

Step 1: Open Gmail App Settings

  1. Open the Gmail app on your iPhone or iPad.
  2. Tap the three horizontal lines (menu) in the top left.
  3. Scroll down and tap Settings.
  4. Tap the email account you want to change.

Step 2: Turn On and Edit the Mobile Signature

  1. Find Signature settings or Signature.
  2. Turn on Mobile Signature (if there’s a toggle).
  3. Type or edit your signature text.
  4. Go back; the change is usually saved automatically.

Again:

  • It’s typically plain text only.
  • It applies only to emails sent from this iOS device using the Gmail app.

If you’re using the built‑in Apple Mail app with a Gmail account, the signature is controlled in iOS Settings > Mail > Signature, not in the Gmail app.

How Multiple Signatures, Accounts, and Devices Change Things

The basic steps are simple, but your actual experience can vary a lot depending on your setup. Some key variables:

1. Web vs Mobile

  • Web Gmail (desktop):

    • Supports multiple signatures
    • Supports rich formatting, images, and links
    • Signature behavior can be customized for new vs reply/forward

  • Mobile apps:

    • Typically one app-level signature per account
    • Usually plain text
    • Works separately from desktop—changing one does not automatically change the other

2. Number of Gmail Accounts

If you have:

  • A personal Gmail
  • A work Google Workspace account
  • Other aliases or addresses added in Gmail

Each one can have:

  • Its own signatures on desktop
  • Its own mobile signature in the Gmail app settings

When you compose, the signature is tied to the From address you select. If you often write from multiple addresses, keeping track of which signature belongs to which address matters.

3. Email Clients vs Gmail’s Own Apps

Some people access Gmail through:

  • Outlook
  • Apple Mail
  • Thunderbird
  • Other third‑party email clients

In those cases:

  • Signatures inside those apps are controlled by the client’s settings, not Gmail’s web settings.
  • You might have a Gmail signature in Gmail web, and a different one in Outlook using the same account.

So changing your signature in Gmail’s web settings won’t update what appears in Outlook or Apple Mail.

4. Level of Formatting You Want

What you can realistically include depends on where you set it:

EnvironmentImagesLinksFormattingMultiple Signatures
Gmail Web (Desktop)YesYesRichYes
Gmail App (Android)RarelyPlainBasicTypically one
Gmail App (iOS)RarelyPlainBasicTypically one
Third‑party clientsVariesVariesVariesDepends on client

Rich, branded signatures with logos and colored text are usually set up on the web version of Gmail, not the mobile apps.

Different User Profiles, Different Signature Setups

The “right” way to change and use a Gmail signature looks different depending on who you are and how you use email.

Casual Personal User

  • Likely uses one personal Gmail address
  • Might mainly want:
    • Name
    • Maybe a phone number
  • Often uses the same device most of the time

Here, a single simple signature set in Gmail web (and maybe copied to mobile) is enough.

Remote Worker or Freelancer

  • May have:
    • Personal Gmail
    • Client or company Google Workspace accounts
  • Often needs:
    • A more detailed professional signature (title, website, portfolio)
    • A shorter reply signature for ongoing threads
  • Sends mail from:
    • Laptop/desktop
    • Phone while on the go

They might:

  • Use multiple signatures in Gmail web (e.g., “Full Work”, “Short Reply”)
  • Use a brief text‑only mobile signature that still looks professional

Team or Business User

  • Often needs:
    • Company branding, logo, legal disclaimer
    • Consistent format across many employees
  • May send from:
    • Laptop with Gmail web
    • Outlook or other client
    • Multiple mobile devices

In this case, changes might be:

  • Managed by an IT admin or central template
  • Applied differently on each platform
  • Combined with other tools (like signature management services)

Privacy‑Focused or Minimalist User

  • Prefers very short signatures
  • Might exclude phone number or location
  • May want no signature on some messages

They might:

  • Disable signatures on mobile entirely
  • Use a minimal one-line signature only on new emails, but not replies

Where Your Own Situation Becomes the Missing Piece

The instructions for changing your Gmail signature are straightforward: open settings, edit or create a signature, choose when it’s used, and save. But the best way to set it up depends on details only you know:

  • How many Gmail accounts you juggle
  • Whether you use Gmail web only, or mix in mobile apps and third‑party clients
  • How formal or branded your emails need to look
  • Whether you want multiple signatures or just a single default
  • How much you care about consistency between phone, tablet, and computer

Once you’re clear on which devices and apps you actually send from, and how polished you want your emails to appear, those same settings in Gmail start to line up differently. The steps don’t change—but the way you choose to use them will.
