We would like to do an A/B Test using two different subject lines (Which is easy). We also want one of the subject lines to contain personalisation (which is also easy). However not everyone has a firstname specified.
When using A/B subject line testing are you able to use AMP scripting in the subject line - so we can add the logic of 'IF FIRSTNAME IS EMPTY THEN SAY 'XXXX' ELSE 'Hi %%firstName, here is your subject line'.
I have tried setting it up - has anyone successfully added AMP scripting in the subject line whilst using AB split tesing?
