We're a very account-centric organization that markets and sells into existing accounts. We also have a formal ABM program consisting of 12-15 global, enterprise accounts where entire campaigns are built around a single account. As most of us know, sending a single email to several contacts at a single company often raises a red flag for potential spam (on the recipient's email server). For those of you that already engage in this type of activity - and beyond using the "random sample" approach to place leads in smaller distribution lists - what sorts of tactics are you using to ensure your email makes it into the user's inbox?
We're participating in Marketo's early adopter program for ABM. One of the items I'd like to see incorporated into Marketo is the ability to automatically stagger email sends (without having to manually setup random samples/static lists) so that they don't get flagged as spam.
