Verifying email addresses is an essential step in maintaining a healthy email list and ensuring successful email campaigns. However, some domains can be challenging to verify, especially those that use email security gateways or have catchall email settings. In this article, we will focus on verifying email addresses at vast.ac.vn using BounceBan, a reliable and accurate email verification service.

About vast.ac.vn

Vast.ac.vn is a domain used by a company in the [industry] sector. The company's email domain is set to catchall, which means that it accepts all emails sent to it, even if the email address does not exist. This can make it challenging to verify email addresses using traditional verification methods.

Challenges of Verifying Emails at vast.ac.vn

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

• Email Security Gateways: It is unclear whether vast.ac.vn uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it can make simple SMTP tests fail, making it difficult to verify email addresses.
• Catchall Emails: Since vast.ac.vn is set to catchall, traditional verification services may not be able to verify email addresses accurately. Simple SMTP tests used by services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work, as they rely on bounce messages to determine the validity of an email address.
• No Bounce Messages: Even if you send test messages to an invalid email address at vast.ac.vn, it may not always return a bounce message, making services like Scrubby not work.

Risks of Not Verifying Emails at vast.ac.vn

Not verifying email addresses at vast.ac.vn can lead to several risks, including:

• High Bounce Rates: If you don't verify email addresses, you may end up with a high bounce rate, damaging your sending reputation and resulting in lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at vast.ac.vn as risky, making it difficult to determine what to do with them. If you keep them, you risk seeing a high bounce rate, and if you delete them, you risk missing potentially valuable valid emails.
