  • How to add a Calendly link to your email signature

    Add a Calendly or Cal.com booking button to your email signature: how to set it up and how it renders in Gmail, Outlook and Apple Mail.

    Published September 28, 2026

    A booking button is an outlined button in your signature's accent color that links straight to your scheduling page, so the reader can book time with you without a reply asking for your availability.

    Add it to your signature

    1. Open your saved signature (make one free in the generator first) and find the "Book a call button" section.
    2. Paste in your booking page URL: Calendly, Cal.com or any other scheduling link.
    3. Type the button text, or leave it blank for the default, "Book a call".

    Where to find your booking link

    • Calendly: open Calendly, go to your Event Types, and copy the link for the event you want people to book - your main scheduling page link works too.
    • Cal.com: open your Cal.com dashboard, go to Event Types, and copy the link for the event, or your public booking page link.
    • Other: any URL that opens a page where someone can book time with you - a Google Calendar appointment link, an internal scheduling tool, whatever you use.

    The button renders as an outlined box, never a filled one: mail clients' dark modes recolor filled backgrounds unpredictably, so an outline and text in your accent color is what survives both light and dark inboxes.

    One button is enough

    A signature with a booking button, a review badge, a photo and a logo all at once reads as clutter, especially on a phone. Most people are better off with one optional block, not several - see what to put in an email signature for the fuller case against a crowded signature.

    On a Company plan

    An owner can set the booking button once for the whole company, on the company page: every member's signature shows it, the same way the logo and color already do. Left blank, each person keeps their own booking button instead. Once the owner sets one, a member sees it read-only in their own editor, marked as set by the company; to change it, an owner edits it on the company's pages.

    Put it in your mail app

    Copy the signature and follow the steps for your mail app - see the install guides for Gmail, Outlook, Apple Mail and more.
