The University of Tokyo is a renowned institution in Japan, and its domain waka.c.u-tokyo.ac.jp is used by various departments and faculties. However, verifying email addresses from this domain can be challenging due to its catchall nature and potential use of email security gateways. In this blog post, we'll discuss the challenges of verifying emails at waka.c.u-tokyo.ac.jp, the risks of not verifying them, and how BounceBan can help.

Challenges of Verifying Emails at waka.c.u-tokyo.ac.jp

Verifying emails at waka.c.u-tokyo.ac.jp can be tricky due to several reasons:

• Catchall Emails: The domain 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.
• Email Security Gateways: There is a possibility that waka.c.u-tokyo.ac.jp uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• No Bounce Messages: Even if you send test messages to an invalid email address at waka.c.u-tokyo.ac.jp, it may not always return a bounce message, making services like Scrubby not work.

Risks of Not Verifying Emails at waka.c.u-tokyo.ac.jp

If you don't verify emails at waka.c.u-tokyo.ac.jp, you risk:

• High Bounce Rate: Not verifying emails can lead to a high bounce rate, damaging your sending reputation, and resulting in lower delivery rates, open rates, and click rates.
• Missing Valuable Emails: If you delete all unverified emails, you risk missing potentially valuable contacts.
• Outdated List: Your email list will be outdated, leading to poor email campaign performance.

Why BounceBan Stands Out

• BounceBan is the only service capable of reliably verifying catchall emails and emails behind email security gateways.
• Services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter are unable to verify catchall emails.
• Approximately 40-50% (increasing over time) of business emails are catchalls, which are not verifiable by other services. BounceBan can accurately verify over 80% of these emails with a 97%+ accuracy rate. Catchall emails that cannot be verified with certainty will be tagged as 'risky', accounting for about 20% or less.
• BounceBan's success rate in verifying catchall emails is on a consistent upward trajectory, verifying millions of emails daily and leveraging advanced AI to recognize patterns and enhance accuracy.
• BounceBan verification is fast, taking only a few seconds for most emails. For a small share of catchall emails, it may take a few minutes. You can verify thousands of emails concurrently.
• BounceBan never has to actually send an email to verify the email like Scrubby does. It uses an AI finetuned with lots of signals to accurately verify all emails, including catchall emails. So it's completely in compliance with GDPR.
