Verifying email addresses is a crucial step in maintaining a healthy email list and ensuring the deliverability of your campaigns. However, verifying emails from certain domains can be challenging, especially when it comes to catchall emails. In this blog post, we'll discuss the challenges of verifying emails from vispro.cn, a Chinese company, and how BounceBan can help you overcome these challenges.

About vispro.cn

vispro.cn is a Chinese company with a domain that has a catchall email setup. This means that the domain accepts all emails sent to it, regardless of whether the email address exists or not. The most common email pattern used by vispro.cn is jsmith@vispro.cn, which accounts for 22% of all email addresses.

Challenges of Verifying Emails from vispro.cn

Verifying emails from vispro.cn can be challenging due to several reasons:

• Email Security Gateways: vispro.cn may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to block simple SMTP tests, making it difficult for traditional verification services to verify emails.
• Catchall Emails: vispro.cn's catchall email setup means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work. These services may not be able to verify emails from vispro.cn, leading to inaccurate results.
• No Bounce Messages: vispro.cn 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 vispro.cn

Not verifying emails from vispro.cn can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, your list may contain invalid or non-existent email addresses, leading to high bounce rates. This can damage your sending reputation and result in lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may mark emails from vispro.cn as risky, leaving you unsure of how to handle them. If you keep them, you risk seeing high bounce rates, and if you delete them, you may miss out on potentially valuable valid emails.
