Personalize preheader based on contact field
Hi guys,
I know that you can personalize the subjectline (like $[UD:SUBJECT||]$) in an email, is this also possible for the preheader?
I've tried putting a field in that way but it just showed me the text (like $[UD:PREHEADER||]$).
If it's not possible, is there a different way for me to personalize the preheader?
Thanks in advance!
Kind regards,
Niels
