Pearl is a SaaS email service provider that transmits outbound mail on behalf of customer domains, routing their messages through Pearl's own mail infrastructure. Organisations using Pearl integrate by configuring their SPF and DKIM records to authorise Pearl's servers as legitimate senders.
Pearl's customer base concentrates among smaller organisations rather than the largest brands, with particular density in the .com space and frequent co-deployment with Google Workspace. For senders, joining Pearl means drawing from a sender reputation pool shared with other Pearl customers. For recipients and mailbox providers, Pearl represents one of many third-party email intermediaries whose infrastructure reputation and abuse posture directly affect whether Pearl-sent mail reaches inboxes.

Pearl functions as an authorised mail relay, appearing in customer SPF records as an include mechanism that permits Pearl's servers to send on their behalf. This shared-infrastructure model means all Pearl customers draw sender reputation from the same IP pools; poor sending practices by any one customer can degrade delivery for others, whilst filtering decisions at major mailbox providers simultaneously affect all users of that Pearl instance.
