In this article, we'll discuss the challenges of verifying emails at vis.ac.at, the risks of not verifying them, and how BounceBan can help you overcome these challenges.

Challenges of Verifying Emails at vis.ac.at

Verifying emails at vis.ac.at can be challenging due to several reasons:

• Email Security Gateways (ESG): There is no information yet about whether vis.ac.at uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to block simple SMTP tests. If they do, it will make it difficult for traditional verification services to verify emails.
• Catchall Emails: vis.ac.at uses catchall emails, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify them.
• No Bounce Messages: vis.ac.at 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 at vis.ac.at

Not verifying emails at vis.ac.at can lead to several risks:

• Risky Emails: Other services may leave most emails at vis.ac.at 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• Outdated List: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
