Hi Marketo community,
I'm wondering what the best practices are around when to start reporting on email metrics. My hunch is that 48-72 hours is enough time for the majority of behavior to be captured, but does anyone have hard stats around the best timing? Additionally, how long should I be running subject line and CTR A/B tests? I've been running them for 7-10 days at a time but would love any additional insights here.
