Is there a limit when using the email preview via email designer for my profile substitutions? I have added around 30 plus to my profile substitutions and the audience is part of the actual targeting but when I use email designer to check preview it is maxing out to 25.
Any help or document around this would be really great.
You can follow this documentation page: Profile Substitution and it says you can select a maximum of 100 profiles for testing. If you're following the steps given in the documentation and still if it's failing open a support ticket.
