We are looking to get a newsletter module designed for our website using which we can send regular emails to over 20,000 customers in our database thrice a week. The module should have the following functionality:
1. Ability to send out emails to all customers within 2-3 hours.
2. Emails should be sent from our domain.
3. Ability to track the response of sent emails - meaning that out of 20,000 emails we should able to tell which ones reached the audience, which ones bounced back, which ones were opened etc.
We would like this module to be hosted on our server.
In case of any further clarifications that might be required, please send a PM.
