Why Verifly flags it

Temporary mailbox domains should be checked before CRM sync.

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.de 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.
