Verifying email addresses is a crucial step in maintaining a healthy email list and ensuring successful email campaigns. However, verifying emails from certain domains can be a challenging task, especially when dealing with catchall emails. In this blog post, we'll discuss the challenges of verifying emails at u4.co.nz, a domain that poses unique obstacles, and how BounceBan can help overcome these challenges.
About u4.co.nz
u4.co.nz is a domain that presents several challenges when it comes to verifying email addresses. With a high likelihood of being a catchall domain, traditional email verification services may struggle to accurately verify emails from this domain. Catchall domains are configured to receive all emails addressed to a specific domain, regardless of the local part (the part before the @ symbol). This makes it difficult for email verification services to determine whether an email address is valid or not.
Challenges of Verifying Emails at u4.co.nz
Verifying emails at u4.co.nz can be challenging due to several reasons:
- Email Security Gateways (ESGs): u4.co.nz may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail. This makes it difficult for traditional email verification services to accurately verify emails.
- Catchall Configuration: As a catchall domain, u4.co.nz may not respond to simple SMTP tests, making it challenging for traditional verification services to verify emails.
- Lack of Bounce Messages: u4.co.nz may not always return a bounce message even if you send a test message to an invalid email address, making it difficult for services like Scrubby to verify emails.
Risks of Not Verifying Emails at u4.co.nz
Not verifying emails at u4.co.nz can lead to several risks, including:
- High Bounce Rates: If you don't verify emails, your list may contain a high number of invalid emails, leading to high bounce rates, damaging your sending reputation, and resulting in lower delivery rates, open rates, and click rates.
- Missed Opportunities: If you delete all unverified emails, you may miss out on potentially valuable contacts.
- Account Restrictions: If your bounce rate is too high, your email service providers may restrict your account.
