Hi @pxljoy and @samliew, thanks for your patience. @samliew, this was changed to the General category from Bug due to fact that the change was not due to an unexpected technical issue but an intended change, sorry for the confusion there.
In the past, form notifications that were sent without the unsub link were being sent to individuals, in some cases without their knowledge, resulting in those individuals marking the emails coming from Webflow as spam.
When emails sent from a bulk mailing system are marked by an excessive amount of Receivers as Spam, this can damage the email reputation of the service, causing mail delivery issues for the entire platform.
To help improve this and prevent the unwarranted email reputation dings and to best serve the community using Webflow, we have added an industry standard Unsubscribe notification to all form submissions.
Other major platforms such as Zapier also have the same kind of system, where unsubscribe links are always provided and is considered “Best Practice” and really should have been implemented in Webflow before this time.
I do apologize for the lack of communication on this change, that is on us to improve that for changes like this in the future.
For now, the recommendation is that if you need to remove the Unsubscribe link, is to first delete the link manually and then manually forward the mail.
The service related to Forms is currently being looked at to see how this can be improved. As soon as there is new updates for this, I will let you know.
Please let me know if you have any questions.
