Newsletter sign-up.
Collect confirmed e-mail addresses with double opt-in and send them straight to Brevo, MailerLite, Mailchimp, Ecomail, SmartEmailing or any service via a webhook – or export them to CSV.
The Newsletter extension adds the Newsletter sign-up element.
- A visitor enters an e-mail address.
- Kaleta sends a confirmation link (double opt-in).
- After the click, the address appears in Content → Subscribers.
Send subscribers to your mailing service
In Extensions → Newsletter choose Brevo, MailerLite, Mailchimp, Ecomail or SmartEmailing, enter the API key and the list, group or audience ID. Every confirmed subscriber is then added to that list, and removed when they unsubscribe or you delete them. Sending, deliverability and unsubscribing from e-mails stay with the service.
- Any other service works through a webhook (Make, Zapier, n8n): the site sends JSON with the event and the e-mail.
- The transfer runs in the background, so visitors never wait; failed attempts are retried.
- Subscribers shows the state of each address, sends all existing subscribers at once and retries the failed ones.
- The API key is stored only on your site and is never shown over MCP.
Or export to CSV
Without a service, export confirmed addresses to CSV, including each subscriber’s unsubscribe link, and import them into your mailing tool. Kaleta does not send newsletters itself.
Unsubscribe and confirmation links keep working even if you later switch the extension off. A sign-up in a pop-up counts as its conversion.
