Description
The MailerLite addon connects WS Form forms to your MailerLite account, mapping form fields to contact fields and registering the lead on the chosen list as soon as the submission is processed. It targets those who capture leads via forms on WordPress and want to feed segmentations, groups, and email marketing automations directly into MailerLite, without exporting CSVs or typing contacts into the service’s panel.
Main Features of MailerLite
- Connection via API key
Links WS Form to the MailerLite account using the API key generated in the service panel. - Field mapping
Associates each form field to a corresponding contact field in MailerLite. - Group assignment
Defines which account groups the new contact will be added to after the form is submitted. - Submission-based sending
Triggers contact registration at the moment the WS Form form is submitted. - Form-specific configurable action
Adds a specific MailerLite action that can be activated independently on each form.
Benefits of MailerLite
- Automated lead capture
New contacts enter directly into the MailerLite account without manual steps between the site and the platform. - Immediate segmentation
Allows organizing subscribers into groups right at the time of registration, accelerating targeted campaigns. - Unified form flow
Centralizes lead collection in WS Form that feeds into different accounts and email marketing lists. - Less data rework
Eliminates exporting, CSV importing, and repetitive typing of contacts in the MailerLite panel.
Who is MailerLite Intended For?
- Those who already maintain lists and automations in MailerLite and want to feed them via WS Form.
- For you who capture leads on landing pages, contact pages, or downloads and need each submission to become a segmented contact.
- Those who create subscription forms for newsletters, ebooks, or events in WordPress and want to sync those submissions with email campaigns.
How to Download MailerLite
MailerLite is available for download here on Ultrapack. After downloading the .zip file, install in Plugins > Add New > Upload Plugin, select the file, and activate the extension. With WS Form already active, MailerLite settings appear as a new action within the options of each form.
When combining API key connection, field mapping, and group assignment into a single WS Form action, MailerLite shortens the path between the submission of a form on WordPress and the trigger of an email campaign. The result is an integration layer that keeps the form design work in WS Form and delegates the email relationship portion to MailerLite.
