We want to gather more data for our subscribers to enhance their profiles and allow us to improve our segmentation. I'd like to email them with a link to a short survey and merge the data we capture into their Klaviyo profile. Can anyone suggest a cheap or free tool I can use to do this?
One colleague has suggested hosting the survey on a web page using a new Klaviyo embed form created specifically for this. But if we did that, how would we merge the data we gather into the existing subscriber profiles?
