Hi @Emil, welcome to the community!
While it’s not possible to add a comment box to an email that someone can fill out without being redirected to a survey form, it is possible to give people to option to give you feedback with one-click.
You could leverage a great feature in Klaviyo, custom profile properties.
The simplest way to do this in the email would be to ask people a question, and then give them a few links or buttons to click with options for their answer. So it could be “yes I like this type of content” or “no I’m not interested.”
Another example could be “what kind of pet do you have” with answers of “I have a cat” or “I have a dog” or “I have a fish.”
This post here has a great video to walk you through how custom profile properties work, and lots of helpful documentation on how to implement what I just described above.
I hope this helps!
