Kit (ConvertKit)

The Kit add-on adds the people who write to you to Kit, formerly ConvertKit: joined to a Kit form, which starts its sequences and automations, tagged, with their first name and your custom fields.

Set it up

1. In Kit, open Settings → Developer and add a new v4 API key.
2. Paste it in Contact Form → Settings → Integrations → Kit and save. The card says Connected when Kit takes it.
3. Open a form, then its Kit tab, and pick a Kit form, tags, or both.

The form’s Kit tab

Setting	What it does
Kit form	They join it as if they had signed up there: its sequences and automations start.
Tags	Tags from your Kit account.
Add them only if they tick	The checkbox where people agree to get your emails. Always for a newsletter sign-up form.
Their email address is in	The first Email field, or the one you pick.
Details to save	Pairs of first_name or a custom field’s key and the form field it comes from. Nothing added: first_name comes from a field called name or first name.

Nothing picked, neither a Kit form nor a tag: this form sends nothing to Kit.

Double opt-in

In Kit, double opt-in belongs to a Kit form: its incentive email asks new subscribers to confirm. With a Kit form picked, new subscribers come in unconfirmed and get that email, when the Kit form has one. With tags only, there’s no Kit form to confirm through, so they come in confirmed.

Someone already in Kit

Anyone can type anyone’s email into a form, so a subscriber Kit already has keeps their name and details: they only join the Kit form and get the tags.

For developers

Nothing is sent while the form is in Test mode.

Hook	What it does
remaily_kit_subscriber	The subscriber sent: ( $subscriber, $form, $tags, $submission ), with email_address, first_name, state and fields. Return an empty array to send nothing.
