MailerLite for Statamic v2 lets you subscribe contact form submissions to your MailerLite subscriber list.
You can optionally add subscribers to groups, automatically split single name fields into name and last name, use an opt-in field, collect GDPR compliant marketing preferences and of course map any custom fields that you like. You can also map multiple form fields into a single field on MailerLite.
