In a short step-by-step guide, I'll show you how to connect the MailerLite newsletter tool (DSGVO compliant) to Webflow and create a form in Webflow, which you can design in Webflow Designer, but still collect new newsletter subscribers in MailerLite.

You can use MailerLite for free with 1000 subscribers via this link:
https://www.mailerlite.com/a/frbntx2y3olu *

*Affiliate link. There are no additional costs for you.

You can take a look at the structure again here via the read-only link:
https://preview.webflow.com/preview/mailerlite-newsletter?utm_medium=preview_link&utm_source=designer&utm_content=mailerlite-newsletter&preview=91e950fef9e1ccdbc111506835440e88&workflow=preview

The whole thing works with the action URL that MailerLite provides us with in their system. To get them, you must first create a new form in MailerLite. What it looks like doesn't matter for now. It just depends on the fields that subscribers should fill out. In the generated HTML code, you will then find all the information you need to store it in the Webflow form. I'll show you how to do that in the video.
