Your problem
My problem is:
In the campaign email, I’ve added a variant.
Default is:
Text A
(Variant) In case of contact field is yes then:
Text B
Those variations are not showing up in Gmail and Thunderbird.
If I press ctrl + u for showing the source code in Thunderbird, I can see that the Text B is there.
These errors are showing in the log:
None, logs are empty.
Steps I have tried to fix the problem:
It seems as if it’s only the variation.
If I remove it, the email is being displayed completely.
