What this means for your email list
Should you accept addresses at this domain?
Treat these as low-value. People use guerrillamail.com to avoid giving a real address, so the contact is unlikely to reply, buy or come back. A real-time check at signup stops them before they enter your list.
Sender authentication
guerrillamail.com has a strict DMARC policy (reject): mail that fails authentication is refused, which protects its brand from spoofing and means anyone sending as guerrillamail.com must have SPF and DKIM set up correctly.
