Acuity Scheduling has a ConvertKit integration, built directly into their product. You can add your customers who purchase products, or schedule services, directly into your ConvertKit email list, right inside the Acuity Scheduling app!
How to configure the integration
Head to your Acuity Scheduling account and navigate to Business Settings. Select Integrations and then click on the ConvertKit logo.
You'll see a screen asking for your ConvertKit API:
You can find your API key inside your ConvertKit Account tab like this:
Head back into Acuity and enter the API in the box provided. Click "Connect to ConvertKit". Then you'll see this page:
Choose the Form, Sequence, or Tag you want to connect your Acuity customers to, and also select the opt-in question so it is clear that you have their permission to add them to your email list.
NOTE: You can only choose one location for your Subscribers to go. If you'd like to be specific about the appointment type that ends up on your list, you can. Let's say, for example, that you had "New Client" and "Existing Client" appointments, but only wanted new clients to be added to a Sequence. To do that, have the opt-in intake Form question only show for the new client appointment types. If the Form doesn't show up for an appointment, then that appointment won't be subscribed in ConvertKit.
To wrap it up, click Save and you're done!
