Challenges of Verifying Emails from valvera.cz

Verifying emails from valvera.cz can be challenging due to several reasons:

• Email Security Gateways (ESG): valvera.cz may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. These gateways can make simple SMTP tests fail, making it difficult for traditional verification services to verify emails.
• Catchall Emails: valvera.cz is set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter cannot verify these emails.
• No Bounce Messages: valvera.cz may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby ineffective.

Risks of Not Verifying Emails from valvera.cz

Not verifying emails from valvera.cz can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, your list will be outdated, and you may end up with a high bounce rate, damaging your sending reputation and resulting in lower delivery rates, open rates, and click rates.
• Account Restrictions: If the bounce rate is too high, your email service providers may restrict your account.
• Risky Emails: Other services may leave most emails at valvera.cz as risky, leaving you unsure of how to deal with them. If you keep the emails, you may risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
