Verifying email addresses is an essential step in maintaining a healthy email list, especially when dealing with catchall emails from domains like ub.lu.se. In this article, we'll explore the challenges of verifying emails from ub.lu.se, the risks of not doing so, and how BounceBan can help you accurately verify these emails.

About ub.lu.se

ub.lu.se is a domain belonging to Lund University, a prestigious institution in Sweden. As an educational institution, ub.lu.se likely has a large number of email addresses, with a significant portion being catchall emails.

Challenges of Verifying Emails from ub.lu.se

Verifying emails from ub.lu.se can be challenging due to several reasons:

• Email Security Gateways (ESG): There is a possibility that ub.lu.se uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to protect their email infrastructure. These gateways can make simple SMTP tests fail, making it difficult for traditional verification services to verify emails.
• Catchall Emails: ub.lu.se may have catchall emails set up, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter cannot verify these emails.
• No Bounce Messages: ub.lu.se 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 ub.lu.se

Not verifying emails from ub.lu.se can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rate, open rate, and click rate.
• Missed Opportunities: If you delete all unverified emails, you risk missing potentially valuable valid emails.
• Account Restrictions: If the bounce rate is too high, your email services providers may restrict your account.
