What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
As far as I know we haven't been sending out anything for a campaign involving Uber Instant Eats.
Did you sign up for that particular form awhile back somewhere perhaps?
Strangely, that form sounds vaguely familiar for some odd reason but I'm not entirely sure.
If it was a jotform user making that form as a mailing list and you signed up for it then you would receive it via their email campaign if anything.
Do you still have the email for it so we can trace and investigate it? If so you can forward it to us at firstname.lastname@example.org and we'll take a look at it.
And are you trying to remove yourself?
You could try replying to the email to see who and what email address it sends a reply.
