Key facts

Intermedia is a mailbox provider that operates hosted email infrastructure for smaller organisations, particularly across .com domains with a US-skewed global footprint.

Its presence concentrates in the long tail rather than amongst the largest brands, meaning senders targeting small and medium-sized businesses will regularly encounter Intermedia mailboxes. The frequent pairing of Intermedia with SendGrid suggests these organisations often combine hosted email with external transactional and marketing mail services.
