Forwarding can cause SPF and DMARC failures. Learn why it happens and what technologies help preserve trust.
Email forwarding is when a mailbox automatically re-sends your email to another address. It’s convenient, but it often breaks SPF because the forwarding server isn’t authorized in your SPF record.
DMARC can fail after forwarding even if your original send was perfect. DKIM can survive if the message isn’t modified, and ARC can help receivers trust the original authentication results.
