Challenges of Verifying Emails at vesla.cz

Verifying email addresses at vesla.cz can be tricky due to several reasons:

• Email Security Gateways (ESGs): vesla.cz might be using 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: vesla.cz uses a catchall email system, which means that traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter might not be able to verify these emails accurately.
• No Bounce Messages: vesla.cz might not always return a bounce message even if you send a test email to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails at vesla.cz

Not verifying email addresses at vesla.cz can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in high bounce rates, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate.
• Risky Emails: Other services might leave most emails at vesla.cz as risky, leaving you unsure of how to handle them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
