According to Live Direct Marketing's daily Tranco top-1M scan (July 13, 2026), Porkbun Email Forwarding is the mailbox provider for 256 domains — 0.04% of 658,711 domains with MX records. Detection method: primary MX record (lowest preference).
Porkbun Email Forwarding is a free email forwarding service operated by Porkbun, a domain registrar and registrant services provider. It allows domain owners to receive mail at their own domain without maintaining a full mailbox—email arriving at a domain address is automatically forwarded to another inbox, usually personal or institutional.
Porkbun Email Forwarding is prevalent among smaller sites in the long tail rather than the largest brands; the service concentrates in the .com registry and skews towards US and global audiences. For email professionals, this footprint matters: smaller sites using email forwarding often maintain weaker email authentication (SPF, DKIM, DMARC) alignment, which can degrade sender reputation and deliverability if proper DNS records are not in place.

Email forwarding services do not send mail on behalf of the domain—they only redirect incoming messages to another address. This can create deliverability challenges: the original sender's infrastructure must be correctly configured with SPF/DKIM/DMARC records, and the receiving domain must align these records with Porkbun's forwarding infrastructure. Many small-site users of Porkbun Email Forwarding do not explicitly configure these authentication records, leaving forwarded mail vulnerable to filtering and reputation-based rejection by strict receiving systems.

Yes; if delivery to a Porkbun-forwarded address fails, first check the receiving domain's email authentication records (SPF, DKIM, DMARC), as misalignment is a common cause of delivery issues with forwarding services.
