Email Infrastructure & ESP Comparisons

These pages compare SuperSend to email service providers (ESPs) and email APIs like SendGrid, Mailgun, and Resend—built primarily for transactional and product email. Many teams use an ESP alongside SuperSend: the ESP handles application mail; SuperSend runs cold outbound (and some teams connect an ESP to orchestrate newsletters or other sends from the same place they run campaigns). For MTA-class infrastructure positioning, see our GreenArrow vs SuperSend cold email infrastructure breakdown. Evaluating self-hosted MTA paths or Postal-style relays? See open source MTA alternatives and Postal server alternatives for outbound stacks. Evaluating commercial relay stacks? See our GreenArrow alternative for outbound-focused setups.

SuperSend vs SendGrid

SendGrid is built for transactional and product email at scale. SuperSend is a cold email sequencer that connects to your sending infrastructure—including SendGrid when you want to route newsletters or other sends through it.

✓SuperSend: cold campaigns, capacity, inbox, and deliverability in one sequencer
✓SendGrid: receipts, auth email, and marketing sends via API—often used with SuperSend, not instead of it
✓Connect SendGrid (or other ESPs) and still run cold outbound with full reply handling
✓Buy domains and mailboxes in SuperSend, or bring Mission Inbox, Mailreef, Infraforge, and more
