We took over a clients email marketing campaigns. They are using "campaigner".
We began using custom designed HTML emails instead of their drag and drop builder that they were using.
The open rates dropped from 25% to 11%. The subjects lines have remained consistent. Besides split testing the design, is there anything else this could be.
(If they aren't opening the email how could it be the design effecting the CTR?)
Thanks so much for any help, thoughts or guesses!
