Challenges of Verifying Emails at zkportal.io

Verifying emails at zkportal.io can be challenging due to several reasons:

• Catchall Emails: zkportal.io uses catchall emails, which can make it difficult for traditional email verification services to verify them accurately. Catchall emails are email addresses that are set up to receive all emails sent to a specific domain, even if the email address does not exist.
• Email Security Gateways: zkportal.io may use email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
• No Bounce Messages: zkportal.io may not always return a bounce message even if you send test messages to an invalid email address at that domain, making services like Scrubby not work.

Risks of Not Verifying Emails at zkportal.io

Not verifying emails at zkportal.io can lead to several risks, including:

• High Bounce Rate: If you don't verify emails, your list will be outdated, and you may risk seeing a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate.
• Undeliverable Emails: If you don't verify emails, you may risk missing potentially valuable valid emails.
