Rediffmail Pro is a mailbox provider offering hosted email services. It appears in the Tranco top-1 million websites predominantly in the .com domain, serving smaller organisations and websites rather than the largest brands.
For email professionals, Rediffmail Pro's position in the long tail of mail hosts—particularly its consistent co-occurrence with Mailgun—reflects a specific archetype: organisations using Rediffmail Pro for received mail and Mailgun for transactional delivery. This pattern affects deliverability strategy; reaching Rediffmail Pro users effectively requires attention to both inbound sender reputation and the outbound authentication protocols of services likely to send mail into Rediffmail Pro inboxes.

Rediffmail Pro's frequent appearance alongside Mailgun suggests a multi-layer email stack where Rediffmail Pro handles received mail whilst Mailgun routes transactional message delivery. This pairing is relevant to deliverability because mail destined for Rediffmail Pro boxes often originates from Mailgun infrastructure; sender reputation, SPF/DKIM/DMARC alignment, and authentication chain completeness all influence filtering decisions at both the ingress (Rediffmail Pro's MX) and egress (Mailgun's SMTP) boundaries.
