Verifying email addresses is a crucial step in maintaining a healthy email list, especially when dealing with domains like vietcas.vn. In this blog post, we'll discuss the challenges of verifying emails at vietcas.vn, the risks of not verifying them, and how to use BounceBan to overcome these challenges.

About Vietcas.vn

Vietcas.vn is a domain used by an organization in the [industry] sector. The company's email domain is set to catchall, which means that it accepts all emails sent to it, regardless of whether the email address exists or not. This setup can make it challenging to verify email addresses using traditional verification methods.

Challenges of Verifying Emails at Vietcas.vn

Verifying email addresses at vietcas.vn can be challenging due to several reasons:

• Email Security Gateways (ESGs): Vietcas.vn may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos to protect their email system. These gateways can make simple SMTP tests fail, making it difficult for traditional verification services to verify email addresses.
• Catchall Setup: As mentioned earlier, vietcas.vn 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 may not work.
• No Bounce Messages: Vietcas.vn may not always return a bounce message even if you send a test message to an invalid email address. This makes it difficult for services like Scrubby to verify email addresses.

Risks of Not Verifying Emails at Vietcas.vn

Not verifying email addresses at vietcas.vn can lead to several risks:

• Risky Emails: Other services may leave most emails at vietcas.vn as risky, leaving you unsure of how to deal with 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.
• Outdated List: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and leading to lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
