Let's be honest most people will compare SME EDM platforms to Mailchimp still. I was an early adopter of that platform and it is interesting to see how it has developed. With Blastable I get the impression they are a top competitor of Mailchimp and other more mature platforms straight out of the gate. This thing delivers and I am looking forward to seeing where it will still go. I purchased Tier 3 and although that meets my immediate and near future needs I'm considering upgrading a further tier or two.
