Click Connect to ConvertKit to Test Your Credentials
If your credentials are correct, you'll be able to select between adding subscribers to a form, or add subscribers to just tags.
Select Forms and Tags, or Just Tags
Using Forms: a current best practice is to create a phantom form and attach your subscribers based on the form name. The benefit of using forms over tags is that tagged subscribers are automatically subscribed with no double-opt-in. If a subscriber is attached to a form, it will ensure double-opt-in so you don't get in trouble with the spam police.
If you are choosing the form route, simply click on the form you'd like the subscribers added to.
Using Tags: if you choose to use Tags instead of forms, please be aware that users will be added without the 2nd opt-in in the double-opt-in workflow.
Additionally, you can add tags to the subscribers. If a tag doesn't exist, you can create a new one.
Add Tags to Subscribers
Adding Custom Fields to subscribers allows you to pass on extra information about that user to ConvertKit.
When you view a user's profile, these custom fields will be present.
Map a Custom Field to a Comment Field or Use a Custom Value
You can also use custom values for the custom field. Just select "Custom Value" from the dropdown and you'll be presented with a text box. Click the "X" button to go back to the dropdown.
Custom Fields With Mapped Name and Custom Comment Status
The last options allow you to set what the user sees on the frontend. You can set the opt-in checkbox text, and also whether the checkbox is enabled by default. To comply with spam rules, it is highly recommended to have this unchecked. Most countries require double-opt-in.
