Verifying email addresses is a crucial step in maintaining a healthy email list, especially when dealing with catchall emails. In this blog post, we'll explore the challenges of verifying emails from Wisers.com.br, a machinery company based in Brazil, and how BounceBan can help overcome these challenges.

About Wisers.com.br

Wisers.com.br is the domain of Wisers Smart Systems, a company operating in the machinery industry. Their email domain is configured as a catchall, which means that all emails sent to non-existent addresses will still be received by the mail server. This setup can make it challenging to verify email addresses using traditional methods.

Challenges of Verifying Emails from Wisers.com.br

Verifying email addresses from Wisers.com.br can be tricky due to several reasons:

• Email Security Gateways: Wisers.com.br might be using email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
• Catchall Configuration: Since Wisers.com.br is a catchall domain, simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be effective.
• No Bounce Messages: Wisers.com.br might not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby ineffective.

Risks of Not Verifying Emails from Wisers.com.br

Not verifying email addresses from Wisers.com.br can lead to:

• High Bounce Rates: If you don't verify emails, your list will become outdated, resulting in high bounce rates, damaging your sending reputation, and affecting delivery rates, open rates, and click rates.
• Risky Emails: Other services may mark most emails from Wisers.com.br as risky, leaving you unsure of how to handle them. If you keep them, you risk high bounce rates; if you delete them, you might miss valuable, valid emails.
