Gmail / Google Workspace Setup

Step-by-step guide to installing your Signkit signature in Gmail and Google Workspace.

Last updated: Jan 1, 2026

This guide walks you through installing your Signkit signature in Gmail. The process works for both personal Gmail accounts and Google Workspace (formerly G Suite) users.

Campaign banners update automatically! Once your signature is installed, any changes to campaign banners in Signkit will appear in Gmail within 5 minutes - no reinstallation required.

Prerequisites

Before you begin, ensure you have:

  • Your Signkit signature created and ready
  • Access to your Gmail account
  • Desktop browser (recommended for setup)

This is the simplest method and works for all Gmail users.

Step 1: Copy Your Signature

  1. Log in to Signkit
  2. Go to Signatures in the sidebar
  3. Click on a signature to open it
  4. Click Copy HTML in the preview panel

A confirmation will appear when the signature is copied to your clipboard.

Step 2: Open Gmail Settings

  1. Open Gmail
  2. Click the gear icon (top right)
  3. Click See all settings
  4. Stay on the General tab

Step 3: Find Signature Settings

Scroll down to the Signature section. You'll see:

  • A dropdown to select which signature to edit
  • Options to create new signatures
  • The signature editor area

Step 4: Create or Edit Signature

For a new signature:

  1. Click Create new
  2. Enter a name (e.g., "Work Signature")
  3. Click Create

For an existing signature:

Select it from the dropdown list.

Step 5: Paste Your Signature

  1. Click inside the signature editor box
  2. Clear any existing content (Ctrl/Cmd + A, then Delete)
  3. Paste your signature (Ctrl/Cmd + V)

Your Signkit signature should appear with all formatting intact.

Step 6: Configure Defaults

Below the editor, set your signature defaults:

  • For new emails use: Select your signature
  • On reply/forward use: Select your signature (or "No signature")

Step 7: Save Changes

Scroll to the bottom and click Save Changes.

Step 8: Test Your Signature

  1. Click Compose to start a new email
  2. Your signature should appear at the bottom
  3. Send a test email to yourself to verify appearance

Method 2: Gmail Mobile App

For iOS and Android Gmail apps:

Mobile Gmail has limited signature support. Complex HTML signatures may not render correctly.

iOS

  1. Open the Gmail app
  2. Tap the menu icon (☰)
  3. Tap Settings
  4. Select your account
  5. Tap Signature settings
  6. Toggle Mobile Signature on
  7. Paste your signature text

Android

  1. Open the Gmail app
  2. Tap the menu icon (☰)
  3. Tap Settings
  4. Select your account
  5. Tap Mobile Signature
  6. Enter or paste your signature
  7. Tap OK

Google Workspace Admin Deployment

If you're a Google Workspace administrator, you can deploy signatures organization-wide.

Using Email Routing Rules

  1. Go to Google Admin Console
  2. Navigate to Apps > Google Workspace > Gmail
  3. Click Compliance
  4. Under Content compliance, add a rule
  5. Configure to append signature HTML to outgoing messages

Using Third-Party Tools

Signkit integrates with Google Workspace for automated deployment. Contact support@signkit.io for enterprise setup assistance.

Troubleshooting

Images Not Displaying

Gmail may block images by default for recipients. Solutions:

  • Ask recipients to click "Display images"
  • Host images on a reputable CDN
  • Ensure image URLs use HTTPS

Signature Not Appearing in Replies

Gmail doesn't automatically include signatures in replies/forwards unless configured:

  1. Go to Gmail Settings
  2. In Signature section, set "On reply/forward use" to your signature
  3. Save changes

Formatting Lost When Pasting

If formatting is lost:

  1. Clear the signature editor completely
  2. Try pasting with Ctrl/Cmd + Shift + V for plain paste
  3. If that doesn't work, paste normally (Ctrl/Cmd + V)

Gmail's editor sometimes strips formatting. If this happens, try using a different browser.

Signature Too Long

Gmail truncates very long signatures. Keep your signature:

  • Under 10,000 characters
  • Maximum 5-6 lines of text
  • Images under 500KB each

Multiple Signatures

Gmail supports multiple signatures:

  1. Create each signature in Gmail settings
  2. Choose which to use when composing
  3. Or set different defaults for new vs. reply emails

Best Practices

Test Before Rolling Out

  1. Send test emails to colleagues
  2. Check on different devices (desktop, mobile)
  3. View in other email clients (Outlook, Apple Mail)

Use HTTPS for Images

Always host images over HTTPS to avoid security warnings and ensure they display.

Keep It Updated

Remember to update your Gmail signature when you:

  • Change your Signkit signature
  • Get a new phone number
  • Change your title or role
