Challenges of Verifying Emails from valvecore.cn

Verifying email addresses from valvecore.cn can be challenging due to several reasons:

• Email Security Gateways (ESGs): There is a possibility that valvecore.cn uses ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. This can make simple SMTP tests used by traditional verification services fail.
• Catchall Emails: valvecore.cn 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: valvecore.cn may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails from valvecore.cn

Not verifying email addresses from valvecore.cn can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate.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