Description
JetFormBuilder MailerLite Action connects JetFormBuilder forms to your MailerLite account, adding a post-submit action that registers the lead directly in a list or group selected in the dashboard. Mapping takes place field by field, linking name, email, and other form data to subscriber attributes, with an optional consent checkbox for lead capture aligned with email marketing best practices.
Key Features
- MailerLite post-submit action: triggers contact registration as soon as the JetFormBuilder form is successfully submitted.
- Field mapping: links form fields to subscriber attributes (name, email, phone, and custom fields).
- Group selection: directs the new contact to a specific list or group configured in MailerLite.
- API key connection: authenticates the integration through an API key entered in the plugin settings.
- Conditional opt-in: lets you condition submission on checking a consent checkbox within the form.
Benefits of JetFormBuilder MailerLite Action
- Automated lead capture: eliminates manual lead exports between the website and the email platform.
- Immediate segmentation: separates contacts by source or interest at the time of registration.
- Unified workflow: keeps forms, automations, and sends centralized in the JetFormBuilder workflow.
- Opt-in compliance: registers only leads that agreed to receive communications through the consent field.
Who Is It For?
- Digital marketing professionals who use JetFormBuilder and MailerLite in the same funnel.
- Agencies that deliver WordPress websites with lead capture integrated with the email platform.
- Stores, infoproduct creators, and blogs that collect newsletter subscriptions through custom forms.
The extension serves those who need to turn JetFormBuilder forms into real lead capture points for MailerLite campaigns, without relying on Zapier or intermediary code. The practical gain appears in reducing friction between the website and the email platform, with leads arriving segmented and ready to enter automation sequences.
