Challenges of Verifying Emails from wistar.upenn.edu

Verifying emails from wistar.upenn.edu can be challenging due to several reasons:

• Catchall Emails: wistar.upenn.edu uses catchall emails, which can make verification difficult. Catchall emails are email addresses that are not explicitly defined but are instead routed to a specific mailbox. Traditional email verification services may not be able to verify these emails accurately.
• Email Security Gateways: There is a possibility that wistar.upenn.edu 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.
• Lack of Bounce Messages: wistar.upenn.edu 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 from wistar.upenn.edu

Not verifying emails from wistar.upenn.edu can lead to:

• High Bounce Rates: Sending emails to invalid or non-existent email addresses can result in high bounce rates, damaging your sending reputation and leading to lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at wistar.upenn.edu as risky, leaving you unsure of how to handle 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.
