How to Add a Signature in Gmail
Step-by-step guide for adding your email signature to Gmail (2026)
Gmail makes it easy to add a professional email signature that appears at the bottom of every message you send. Whether you're setting up a signature for the first time or updating an old one, this guide walks you through the entire process. The steps work for both personal Gmail accounts and Google Workspace (formerly G Suite) accounts used by businesses.
Click the gear icon in the top right corner of your Gmail inbox. You'll see a quick settings panel pop up. Don't stop there — click the 'See all settings' button to access the full configuration menu where signature options live.
You're now in the General tab, which is perfect. Scroll down past the language settings and vacation responder until you spot the 'Signature' section. This is where Gmail keeps all your signature tools, including the option to manage multiple signatures if you need them.
Hit the '+ Create new' button to start fresh. Gmail will ask you to name this signature — pick something you'll recognize later, like 'Work' or 'Professional'. If you already have an old signature, you can either edit it or create a new one and delete the old version afterward.
Here's where your SigGen signature comes in. Copy the HTML from SigGen's export panel (use the 'Copy HTML' button), then paste it directly into Gmail's signature editor. Gmail handles HTML signatures really well, so your formatting, images, and links should all come through perfectly.
Scroll down a bit to find 'Signature defaults'. This section lets you choose which signature appears on new emails versus replies and forwards. Pick your newly created signature from both dropdowns if you want it everywhere, or mix and match if you have multiple signatures set up.
Almost done! Scroll all the way to the bottom of the settings page and click the 'Save Changes' button. Gmail will reload, and your signature is now active. Send yourself a test email to make sure everything looks right before you start using it with clients or colleagues.
Troubleshooting Common Issues
Gmail sometimes blocks external images for security reasons. Make sure you're copying the full HTML from SigGen (not just plain text). If images still don't load, check that image URLs are publicly accessible and use HTTPS. You can also try uploading images directly through Gmail's image insert tool instead.
This usually happens when Gmail strips out certain CSS styles. SigGen generates signatures optimized for Gmail, but if you manually edited the HTML, stick to inline styles only. Gmail's editor can also mess with formatting when you paste — try using 'Paste without formatting' (Ctrl+Shift+V) if your signature looks weird.
Gmail mobile apps handle signatures separately. Open the Gmail app, tap your profile icon, go to Settings, select your account, and enable 'Mobile Signature'. You might need to paste your signature separately in the mobile app — desktop and mobile signatures aren't automatically synced.
Check that your links include the full URL with https:// at the beginning. Gmail won't automatically convert partial URLs like 'example.com' into clickable links. Also verify that you didn't accidentally break the link when pasting — sometimes extra spaces sneak in and break the HTML.
Tips for Gmail Signatures
Gmail lets you create several signatures and switch between them. Set up a formal one for client emails and a casual one for internal team communication. You can quickly change which signature to use before sending any email.
Gmail's mobile app truncates long signatures, so aim for 4-5 lines max. Include only essential info: name, title, company, phone, and one link. Save the full resume for LinkedIn.
Always send a test email to yourself first. Check how it looks on desktop, mobile, and in dark mode if you use that. Gmail's signature preview in settings doesn't always match what recipients actually see.
Large image files slow down email loading and can trigger spam filters. Keep your photo under 50KB and logos even smaller. SigGen automatically optimizes images, but if you're adding custom graphics, compress them first.
