About Zerno.co

Zerno.co is an electrical and electronic manufacturing company based in Chicago, Illinois, United States. The company's domain, zerno.co, has a catchall setup, which can make it difficult to verify email addresses.

Challenges of Verifying Emails at Zerno.co

Verifying email addresses at Zerno.co can be challenging due to several reasons:

• Catchall Setup: Zerno.co's domain is set to catchall, which means that simple SMTP tests used by traditional verification services may not work.
• Email Security Gateways: Zerno.co may use email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make it difficult to verify emails using simple SMTP tests.
• No Bounce Messages: Zerno.co may not always return a bounce message even if you send test messages to an invalid email address, making it challenging for services like Scrubby to verify emails.

Risks of Not Verifying Emails at Zerno.co

Not verifying emails at Zerno.co can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, your email list may be outdated, resulting in high bounce rates, damaging your sending reputation, and lowering delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at Zerno.co as risky, making it difficult to decide what to do with them. If you keep them, you risk seeing high bounce rates; if you delete them, you risk missing potentially valuable valid emails.
