Why is email send throttling in Marketing Cloud finishing earlier than expected? I did a User-Initiated send to 190k contacts throttled from 4:30pm-8:30pm with a max limit of 50k/hr. I would expect it to finish at 8:30 or close to it, however it finished 1hr earlier at 7:35pm. Our time zones are set up correctly.
Also does anyone know what the actual throttling behaviour is? Is it sending the max limit as a large batch send precisely on the hour or drip feeding every few minutes throughout the whole throttling window?
