Unfortunately there is no way to remove it.
From what I’ve read here, Webflow’s transactional email provider Mailjet requires it. Unfortunately, adding this in was not announced or well-thought, and it competes with the Reply-To template feature.
If you use that Reply-To feature with the name & email of the person submitting the form, and your client replies to the form notification, that end-user will get the message. But they also get the unformatted form contents, and the unsubscribe link.
Basically Webflow cannot turn the unsubscribe link feature off, so you have a few options;
- Avoid using the Reply-To template, and force your clients to click the email in the form content to reply.
- Use Zapier/Make + your own transactional email provider directly, setup for the client, with their own email & domain as the sender. There you can create formatted messages, choose which Forms send where, and template your Reply-To safely.
- Avoid email altogether, and use Zapier/Make to push leads into an SFA system like Salesforce, Pipedrive, or Nutshell.
I setup systems like this for a lot of clients, so PM me if you need some assistance building that.
