We are a online marketing company working with permission marketing. We have several mailinglists and a total of 200,000 subscribers. This number grows rapidly, and our target is 500,000 within a year. We currently send about 6 million e-mails per month - this number will grow as well... We are using OEMPro and InterSpire E-mail marketer to manage our lists, but we are facing the same delivery problems as many other companies. Therefore we are looking for a complete solution, which will improve our delivery rate significantly.
Therefore I am doing some research to find the best solution for our needs.
Our main priorities are:
Guaranteed delivery to hotmail, yahoo and other free e-mail services.
To avoid our newsletters from being deleted by spam/content filters.
Superior bounce and member activity handling.
User friendly template based newsletter design interface.
Unlimited custom fields.
Filtering and scheduling options.
Superior tracking facilities.
We are looking for a solution which can be installed on our own servers.
With this message, I am hoping to hear experiences from users of different solutions.
