The University of Petroleum (East China) is a prestigious institution located in Shanghai, China, specializing in the oil and energy industry. As a prominent player in the energy sector, the university's email domain, upc.edu.cn, is an essential communication channel for its faculty, staff, and students. However, verifying email addresses from this domain can be a daunting task due to its catchall nature and potential email security gateways.

Challenges of Verifying Emails at upc.edu.cn

Verifying emails at upc.edu.cn poses several challenges. Firstly, the domain may employ email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, and others, which can make simple SMTP tests fail. Moreover, the domain is set to catchall, making it difficult for traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter to verify emails accurately. Additionally, the domain may not always return a bounce message even if you send test messages to an invalid email address, rendering services like Scrubby ineffective.

Risks of Not Verifying Emails at upc.edu.cn

Failing to verify emails at upc.edu.cn can lead to severe consequences. Other services may categorize most emails from this domain as risky, leaving you unsure of how to proceed. If you keep the emails, you risk experiencing a high bounce rate, while deleting them might result in missing potentially valuable valid emails. An unverified email list can become outdated, leading to a high bounce rate, damaging your sending reputation, and ultimately affecting your delivery rate, open rate, and click rate. In extreme cases, your email service providers may restrict your account.

Why BounceBan Stands Out
