Hardcore IM'er from back in the day here.
Finished my degree, moved to a new city, got a great job - let my online work virtually disappear for years & most everything is gone. I'd like to start up & over again from square one.
I have a list with about 23 million emails, and another with about 7 million. About 70% are opt-in, other 30% GI. I would imagine after some validation I'd end up with anywhere from 250k to 1.5 million good emails left.
Because internet time is vastly different from real time; I was hoping for some tips, suggestions, input etc. for what you guys think might be the best route to go with all of this data essentially at square 1.
I look forward to your replies - thank you!
EDIT: I'm aware of the fact that I'd need to refresh the opt-ins; thank you though if this was something you were about to suggest - definitely interested in hearing methods on how to do this efficiently by all means.
