The University of Tokyo, a prestigious institution in Japan, uses the domain um.u-tokyo.ac.jp for its email communication. With a large number of emails being sent and received daily, verifying the authenticity of these emails is crucial to maintain a healthy email list and prevent bounces. However, verifying emails from um.u-tokyo.ac.jp can be challenging due to its catchall nature and potential use of Email Security Gateways (ESGs).

Challenges of Verifying Emails at um.u-tokyo.ac.jp

Verifying emails from um.u-tokyo.ac.jp can be a daunting task due to several reasons:

• Catchall Emails: um.u-tokyo.ac.jp 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 be able to verify these emails.
• Email Security Gateways (ESGs): There is a possibility that um.u-tokyo.ac.jp uses ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. This can make simple SMTP tests fail, making it difficult to verify emails.
• Lack of Bounce Messages: um.u-tokyo.ac.jp may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby not work.

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

Not verifying emails at um.u-tokyo.ac.jp can lead to several risks:

• Risky Emails: Other services may leave most emails at um.u-tokyo.ac.jp as risky, making it difficult to decide what to do with them. If you keep the emails, you may 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• Outdated List: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and subsequently, lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
