SuperSend is a managed cold email infrastructure platform for teams that need to send at high volume without assembling their own stack of servers, sender identities, warmup, deliverability monitoring, and reply handling. The product is positioned around dedicated infrastructure and managed operations rather than a standalone sequencer or shared ESP.
The site says SuperSend provides dedicated servers and IPs, sender identity provisioning, warmup on a 30,000-mailbox network, placement testing, bounce analysis, and a unified inbox for replies. Pricing is scoped to sending volume on a call, with a flat platform fee plus a per-send rate.
