WB4B/C' Negócios Online, a Brazilian company operating in the internet industry, presents a unique challenge when it comes to verifying email addresses. Their domain, wb4b.com.br, uses a catchall email setup, making it difficult for traditional email verification services to accurately verify email addresses. In this blog post, we'll explore the challenges of verifying emails from wb4b.com.br and how BounceBan can help.
Challenges of Verifying Emails from wb4b.com.br
Verifying email addresses from wb4b.com.br can be a daunting task due to several reasons:
- Email Security Gateways (ESGs): wb4b.com.br 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.
- Catchall Emails: wb4b.com.br uses a catchall email setup, which means that simple SMTP tests used by traditional verification services may not work.
- No Bounce Messages: Even if you send test messages to an invalid email address at wb4b.com.br, it may not always return a bounce message, making it difficult for services like Scrubby to work.
Risks of Not Verifying Emails from wb4b.com.br
Not verifying email addresses from wb4b.com.br can lead to:
- High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and affecting your delivery rate, open rate, and click rate.
- Risky Emails: Other services may leave most emails at wb4b.com.br as risky, leaving you unsure of how to deal with them. If you keep them, you risk seeing a high bounce; if you delete all of them, you risk missing potentially valuable valid emails.
