I've used Interspire with some success for awhile back then, and am recently coming back and putting in more resources to make mailing a sustainable part of our portfolio. Really considering going for ThroughputMTA but I'd like to hear your thoughts about Interspire? Every occasional reference I've heard to Interspire on MF has been shitty, but what exactly is so bad about it? For a start we plan to send to 100k to 200k names a day, and just bought a server and installed Interspire on it, have 1MM names for this last experiment with Interspire to see just how bad it is before perhaps going for Throughput MTA next month on. Thanks in advance for any advice!
