DirectIQ is quite diffrent from other email marketing. It is easy to use rather than other and also easy to review all activities.

I like the Spam Doctor function. It offers a diagnostic report, which details which email clients (Yahoo, Gmail ..) will analyze my messages as spam

I must say that its free templates are quite good, and it offers a lot to those who do not have the money to pay the month for services, I am mainly attracted to social networks and contact management sources. It's great to be able to edit contact details. and it is very easy to re-enable contacts that were not subscribed.
