Why Verifly flags it
Temporary mailboxes from this family are commonly filtered from signup and CRM lists.
Disposable domains are not automatically malicious, but they are weak long-term contact points. Segment them before billing, onboarding, CRM enrichment, or campaign sends.
What to do next
- Separate addresses using guerrillamail.com from normal business and consumer inboxes.
- Run a full verification pass before sending campaigns or accepting important product accounts.
- Use stricter rules for signup, abuse prevention, and free-trial flows than for low-risk newsletters.
This page is a watchlist lookup, not a final deliverability verdict. Verifly can verify the actual mailbox and show deeper signals before you import or send to the address.
