Careful how you segment your database

crewI received promational emails from Crew Clothing today.  I’ve bought from them regularly, so straight into my inbox – great let’s have a look.

But for some reason I’m on their mailing list twice and to one email address they are offering me 15% off and the next 20% off PLUS free delivery.  Just makes them look a bit foolish…

So, before you test messages to different parts of your mailing list, check that you have de-duplicated on something other than email address – mailing address or phone number would be good.
