Challenges of Verifying Emails at zaffke.co

Verifying emails at zaffke.co can be tricky due to several reasons:

• Email Security Gateways (ESGs): zaffke.co may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Emails: zaffke.co uses a catchall email domain, which means that traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails accurately.
• Lack of Bounce Messages: zaffke.co may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby ineffective.
