Verifying email addresses is a crucial step in maintaining a healthy email list, especially when it comes to domains like u.tsukuba.ac.jp. In this blog post, we'll explore the challenges of verifying emails at u.tsukuba.ac.jp, the risks of not verifying them, and how BounceBan can help you overcome these challenges.

Understanding u.tsukuba.ac.jp

u.tsukuba.ac.jp is a domain used by the University of Tsukuba, a Japanese national university located in Tsukuba, Ibaraki. The university is known for its academic excellence, research, and innovation. With a large community of students, faculty, and staff, the university's email system is likely to be robust and secure.

Challenges of Verifying Emails at u.tsukuba.ac.jp

Verifying email addresses at u.tsukuba.ac.jp can be challenging due to several reasons:

• Email Security Gateways (ESGs): u.tsukuba.ac.jp might use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to secure their email system. These gateways can make simple SMTP tests fail, making it difficult for traditional verification services to verify email addresses.
• Catchall Emails: u.tsukuba.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 email addresses. Catchall emails are email addresses that are not explicitly defined but are still accepted by the mail server.
• No Bounce Messages: u.tsukuba.ac.jp 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 u.tsukuba.ac.jp

Not verifying email addresses at u.tsukuba.ac.jp can lead to several risks:

• High Bounce Rate: If you don't verify email addresses, your list may contain invalid or non-existent email addresses, leading to a high bounce rate. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates.
• Missing Valuable Emails: If you delete all unverified email addresses, you may miss potentially valuable emails.
• Outdated List: An unverified email list can become outdated quickly, leading to a high bounce rate and damaging your sending reputation.
