The ESP supports tracking, but Anymail can’t enable/disable it for individual messages. See the ESP detail page for more information.

Trying to choose an ESP? Please don’t start with this table. It’s far more important to consider things like an ESP’s deliverability stats, latency, uptime, and support for developers. The number of extra features an ESP offers is almost meaningless. (And even specific features don’t matter if you don’t plan to use them.)
