Assuming a dedicated IP, simple smart list and flow steps - how long should I expect a campaign of 300-400K emails take to be sent through Marketo?
I've done some benchmarking in terms of uploads of 5m and 10m records as well as extraction, but I don't think there's an easy answer on the send. Unless things have changed, Marketo tries to throttle emails so they don't look like an attack so the times may vary. I can tell you from personal experience seeing a few instances where a blast this size (in separate and different instances) took over a day and a half to complete on a shared IP.
Thanks Ryan! Marketo support advised that we should expect 300-400K messages to take about an hour using a simple smart list and flow (and I'd assume) our dedicated IP. We elected not to send this campaign, but if we do so at a later date I'll track throughput and share what we experience.
Cool. I'll let you know if I run into some larger campaigns as well on a shared or dedicated IP and see what the results look like.
