I'm am using Listmail Pro for my Solo Ads business and there is one feature that is available in aWeber but not currently in Listmail Pro. It would be a great enhancement if you do this.
aWeber allows you to schedule multiple messages to go out at specific times. It's really useful for Solo Ad sellers. We can schedule an email message to go in the morning and the evening.
If you were to make this modification I know a bunch of Solo Ad sellers who are not happy with aWeber and would love to host their own auto-responder. I have integrated it with Mandrill and it works great. If you could make the changes I would make up a training video to teach all of these people how to use it in their Solo Ad businesses. This means lots of new sales.
This really is an amazing product. I love it and swear by it.
Thanks,
Steve Wilson
