  1. After digging into the details with InfiniteMho, it seems like one customer in particular accounted for SendGrid’s spam trap uptick in May. We will reach out to the customer, review their address acquisition practices, and get them back on the straight and narrow. Thanks for bringing this to our attention.

    • Indeed. They were still mailing in the first half of June, which also explains why SendGrid were still slightly ahead of ET in June. Their two blasts on June 4 and 11 amounted to 9% of SG’s total output as seen in the traps; without it, SG would have been just slightly behind ET.
