Challenges of Verifying Emails at un.tsukuba.ac.jp
Verifying email addresses at un.tsukuba.ac.jp can be challenging due to several reasons:
- Catchall Emails: un.tsukuba.ac.jp is a catchall domain, which means that it accepts all emails sent to it, regardless of whether the email address exists or not. This makes it difficult for traditional email verification services to accurately verify emails using simple SMTP tests.
- Email Security Gateways (ESG): It's unclear whether un.tsukuba.ac.jp uses ESGs 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: un.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 un.tsukuba.ac.jp
Not verifying emails at un.tsukuba.ac.jp can lead to several risks, including:
- High Bounce Rates: If you don't verify emails, you may end up with a high bounce rate, which can damage your sending reputation and result in lower delivery rates, open rates, and click rates.
- Outdated Lists: Failing to verify emails can lead to outdated lists, which can negatively impact your email marketing campaigns.
- Risky Emails: Other services may leave most emails at un.tsukuba.ac.jp as risky, making it difficult to know how to deal with them. If you keep the emails, you may risk seeing a high bounce; if you delete all of them, you risk missing potentially valuable valid emails.
