Gmail Button Inserter – Add CTA Buttons to Emails

Add clickable CTA buttons to Gmail emails in one click. Email-safe buttons that look right in Outlook, Apple Mail and on mobile.

Gmail has no built-in way to insert a real button. You're stuck with plain hyperlinks, or pasting HTML that breaks the moment it hits someone's inbox. Gmail Button Inserter adds a button control directly to Gmail's formatting toolbar, so you can drop a styled, clickable call-to-action into any email without leaving the compose window. How it works 1. Open a Gmail compose window 2. Click the button icon in the formatting toolbar 3. Set your label, destination URL, colour, and shape 4. Insert — the button appears inline, ready to send Features 1. Insert clickable CTA buttons straight from the Gmail toolbar 2. Customise button text, link, background colour, text colour, corner radius, and padding 3. Email-safe HTML that renders correctly in Gmail, Outlook, Apple Mail, and mobile clients 4. Works inside the normal compose window — no separate editor, no copy-paste 5. No account required, works immediately after install Who it's for: 1. Freelancers sending proposals. 2. Founders doing cold outreach. 3. Sales reps who want a "Book a call" button that gets clicked. 4. Recruiters sharing application links. 5. Anyone sending a newsletter from Gmail. 6. Support teams linking to help docs. 7. Marketers testing CTA copy without opening a full email platform. Why a button instead of a link A styled button is visually distinct from body text and gives the reader one obvious action to take. Plain text links get skimmed past. Privacy: Gmail Button Inserter does not read or transmit your email content, button text, or link URLs. Buttons are created on your device. The free extension includes 3 buttons. After that, Pro is $19, paid once. You receive a license key by email and paste it into the extension to keep using it. Anonymous usage events can be turned off in settings.
