We've just launched our completed integration into the Microsoft Junk Mail Reporting System. This means that you can now keep track of anyone who flags your campaigns as spam across all Hotmail and MSN accounts.
Whenever you receive a spam complaint, that recipient is instantly removed from your list and we provide you with a detailed report on who made the complaint and when.
Just like the existing AOL spam complaint integration, we're also using this data to monitor complaints for all our customers to make sure everyone is sticking to best practice. If one of you guys is getting complaints greater than 1 in every 5,000 emails, you'll more than likely be hearing from us.
Having said that, we certainly understand (as do most ISP's) that some of your recipients may forget opting in to your list and occasionally mark an email as spam instead of just unsubscribing. At any rate, here are a few tips to follow to reduce the chances of an unjustified spam complaint:
Using our double opt-in subscribe process to ensure a high quality subscriber list.
Inform your recipients why they are receiving each email and how you obtained their details in a clear location at the top of each email.
Including our single-click unsubscribe link in an obvious, prominent position.
We've got a few other features we plan on adding to our spam reporting soon that should certainly please our bigger senders. We'll announce them here as soon as they're live.
