In Marketing Cloud, I am facing error message : "A profile center link is missing from this email. For template based email, please contact our customer service."
What should I do ?
You need to add the required Personalization Strings to your email HTML as outlined in the error message:
Just to add to this, we found we were getting click throughs using the scripting hack from Adam so changed to the solution from Data_Kid.
This sometimes displayed the ridiculously long link for (at least) Windows users on Outlook 16 so am now using:-
<div style="display:none"><a href="%%profile_center_url%%">.</a></div>
which displays a fullstop at worst.
