As a business owner or marketer, you understand the importance of having accurate and reliable email lists. One of the biggest challenges in email verification is dealing with catchall emails, which can be notoriously difficult to verify. In this blog post, we'll explore the challenges of verifying emails from u51.com, a leading credit card manager company, and how BounceBan can help you overcome these challenges.
About u51.com
u51.com is a Chinese company that specializes in credit card management. With a strong online presence, the company uses email communication to connect with its customers and partners. However, verifying emails from u51.com can be a daunting task due to its catchall email setup.
Challenges of Verifying Emails from u51.com
Verifying emails from u51.com can be challenging for several reasons:
- Catchall Emails: u51.com uses a catchall email setup, which means that a single email address can receive emails intended for multiple recipients. This makes it difficult for traditional verification services to determine whether an email is valid or not.
- Email Security Gateways: u51.com may use email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out spam and malicious emails. These gateways can block simple SMTP tests, making it difficult to verify emails.
- Lack of Bounce Messages: u51.com may not always return a bounce message even if you send a test email to an invalid email address. This makes it difficult for services like Scrubby to verify emails.
Risks of Not Verifying Emails from u51.com
Not verifying emails from u51.com can lead to several risks, including:
- High Bounce Rates: If you don't verify emails, you may end up sending emails to invalid addresses, resulting in high bounce rates. This can damage your sending reputation and lead to lower delivery rates, open rates, and click rates.
- Risky Emails: Other services may flag emails from u51.com as risky, leaving you uncertain about how to handle them. If you keep them, you risk seeing high bounce rates, and if you delete them, you risk missing potentially valuable emails.
