Connect SendGrid with Cal ID
Deliver booking confirmation and reminder emails via SendGrid.
The SendGrid integration connects SendGrid with Cal ID so you can send booking updates to your team with no manual work. It fits teams who coordinate in chat and want scheduling activity where they already work. Once you link the two, every booking, reschedule, and cancellation flows through SendGrid automatically, and your Cal ID booking pages keep working exactly as before. It sets up in about a minute from the app directory and is free on every Cal ID plan, with no extra fees.
