Your details

Link to one specific booking link (e.g. your 30-minute call), not your whole booking page — fewer decisions, more bookings.

Rich text is what most signature editors want. Use the HTML if your client has a source or HTML mode.

Show the HTML

Table-based, inline styles only, no images — so it survives Gmail, Outlook and Apple Mail without a hosted asset.

Paste it into your email client

The same copied signature works everywhere; only where you paste it changes.

Gmail
  1. 1Click "Copy as rich text" above.
  2. 2In Gmail, click the gear icon → See all settings. Stay on the General tab and scroll to Signature.
  3. 3Click Create new, name it, then click inside the signature box and paste (Ctrl+V / Cmd+V). The button and link come through formatted.
  4. 4Under Signature defaults, choose it for both FOR NEW EMAILS USE and ON REPLY/FORWARD USE.
  5. 5Scroll to the bottom and click Save Changes — Gmail does not save automatically.

If you use Send mail as with several addresses, each address has its own signature default.

Outlook (new / web)
  1. 1Click "Copy as rich text" above.
  2. 2In new Outlook or Outlook on the web, click the gear icon → Accounts → Signatures (older builds: View all Outlook settings → Mail → Compose and reply).
  3. 3Click + New signature, name it, click into the editor and paste.
  4. 4Under Select default signatures, set it for New messages and for Replies/forwards.
  5. 5Click Save.

The new Outlook stores signatures with your account, so it follows you to other devices signed into the same mailbox.

Outlook (classic desktop)
  1. 1Click "Copy as rich text" above.
  2. 2Windows: File → Options → Mail → Signatures. Mac: Outlook → Settings → Signatures.
  3. 3Click New, name the signature, click into the edit box and paste.
  4. 4Choose it in the New messages and Replies/forwards dropdowns, then click OK.

Classic Outlook on Windows renders email with Word's engine; the table-based markup here is built for exactly that, which is why there is no CSS and no images.

Apple Mail
  1. 1Click "Copy as rich text" above.
  2. 2Open Mail → Settings (or Preferences) → Signatures. Select the account on the left and click +.
  3. 3Click into the signature area on the right and paste.
  4. 4Untick "Always match my default message font" so the colours and button survive.
  5. 5Pick it under Choose Signature at the bottom. iPhone and iPad have a separate plain-text signature under Settings → Mail → Signature; the button will not appear there.

Why a button, and why no image

A booking link in a signature is a standing invitation: every email you send carries it, to exactly the people you most want meetings with. A button gets noticed where a bare URL in grey text does not — but most signature generators draw that button as a hosted image, which many clients block by default, which breaks when the hosting changes, and which shows a broken-image icon to the people you are trying to impress.

This generator draws the button with a table cell and a background colour instead. It is the technique transactional-email templates have used for years because it renders in Gmail, Outlook on the web, classic Outlook on Windows (which uses Word's rendering engine), Apple Mail and most mobile clients without any external file. The plain link underneath is a fallback for the few clients that strip styling entirely.

Frequently asked

How do I add a booking link to my email signature?
Fill in your name, title and booking URL above, click "Copy as rich text", then paste into your email client's signature editor: Gmail (Settings → See all settings → Signature), Outlook (Settings → Accounts → Signatures, or File → Options → Mail → Signatures in classic), or Apple Mail (Settings → Signatures). Set it as the default for new messages and replies, then send yourself a test email.
Is the signature really free, and is anything stored?
Yes and no respectively. The generator runs entirely in your browser; nothing you type is sent to SynqSlot or anyone else. You do not need an account, and you can use any booking URL — SynqSlot, Calendly, Cal.com or your own page.
Why does the button look different in some email clients?
Email clients support different subsets of HTML. This signature uses a nested table with inline styles and a background colour on the cell, which is the most widely supported way to draw a button without an image. Rounded corners are dropped by a few clients (classic Outlook on Windows), but the button stays a solid, clickable block everywhere.
Should I link to my whole booking page or one specific booking link?
One specific link, almost always. A direct link to your 30-minute call removes a decision from the reader, and removing decisions raises completion. Use the main booking page only if you genuinely offer different kinds of calls to the same people.
What should the button say?
State the length and the outcome: "Book a 15-minute intro" or "Grab 30 minutes with me" outperform "Schedule a meeting". Avoid "Click here". Keep it under about 30 characters so it stays on one line on phones.
Can I use this with Gmail's mobile app or iPhone Mail?
Gmail's mobile apps use a plain-text signature set in the app, and iPhone Mail has its own signature under Settings → Mail → Signature. Neither renders the button. For mobile, add a plain line such as "Book a call: synqslot.com/yourname/30min" — a short, readable URL is the whole point of a scheduling link.
