The last time SendGrid was NOT number 1 in these stats was May 2021. Incidentally, that’s the previous time this blog was updated.

Amazon SES has more or less permanently taken over from Mailchimp as #3.

The entry of the Chinese ESP SendCloud / uCloud to these lists did in fact happen earlier, but it seems we’ve only tweeted about that at the time.

Here’s a list of the individual customers with the most volume from the whole bunch, their percentages out of the total ESP mail load, their respective ESPs, and their percentages out of their own ESP:
