After testing the Facebook like feature I notice a minor detail that is quite annoying. When someone likes the campaign, and the campaign has a dynamic personalisation of the subject line...a poor "fallback" text is displayed on Facebook.
So if I like our campaign the like text on Facebook would read: "John Doe likes Hello [fullname,fallback=customer], here's our news for today on createsend.com"
This should be improved.
Thanks for letting us know. We have fixed this problem in the upcoming release, and will notify you in this thread when the fix goes live. Thanks for your patience in the meantime.
This fix has been published now.
