We sometimes get asked if dotMailer will allow one email address to belong to the same mailing list twice with different associated data. To most people this might seem like a strange request but some companies do hold multiple customer records that share the same address. For example Mr and Mrs Smith might both register for online shopping using theSmiths@hotmail.com. The retailer will want to email them separately through the same email address with different messages!

Unfortunately for people wishing to do this, our answer has to be 'no' and so I thought I'd explain why this is in a bit more detail.
