Wait until you get to customer support. Sendgrid is a joke. The only solution was a chargeback that they didn't fight.
Unless you want to send your friend a birthday reminder once a year, do not invest time (and money) into Sendgrid. Once you start growing, they will cause you a serious headache once dropped and need to move on while you operating.
And yes their stats looks fancy but are useless. I also pointed few flaws in their stats that make them look my spam rate much higher than it really was - no response.
