I have used Mailchannels at several different companies. On one of our accounts we regularly do over 100 million emails per month through Mailchannels without any issues.

We have tried to roll our own in-house anti-spam filtering systems before, but none of them worked as well as Mailchannels and the cost of keeping a mail administrator on staff was more than the cost of our annual Mailchannels bill. On top of that, it freed up a lot of resources in our Abuse Team to work on other issues and generally made customers happier with our service because they were not having mail delivery issues anymore due to blacklisted mail servers. I highly recommend giving Mailchannels a shot, it is a great service and a great group of people running it.

We've been using mailchannels for a couple years now and couldn't be happier. It's not only reduced our support costs and removed the pain of constant mail server blacklisting but with the new WHMCS module we've opened up a new revenue stream by offering these services to our channel partners and resellers.
