As a business owner or marketer, you understand the importance of verifying email addresses to maintain a healthy email list and prevent bounces. However, verifying emails from certain domains can be a challenge, especially when dealing with catchall emails. In this article, we'll focus on verifying emails from wisefour.com.br, a management consulting firm based in Brazil.

About Wisefour.com.br

Wisefour Customs Experts is a management consulting firm that operates in the industry of management consulting. The company is headquartered in Campinas, São Paulo, Brazil, and uses the domain wisefour.com.br for its email communications.

Challenges of Verifying Emails at Wisefour.com.br

Verifying emails at wisefour.com.br can be challenging due to several reasons:

• Catchall Emails: Wisefour.com.br uses catchall emails, which means that a single email address can receive emails addressed to multiple usernames. This makes it difficult for traditional email verification services to accurately verify email addresses.
• Email Security Gateways: Wisefour.com.br may use 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.
• No Bounce Messages: Wisefour.com.br may not always return a bounce message even if you send test messages to an invalid email address at that domain, making services like Scrubby not work.

Risks of Not Verifying Emails at Wisefour.com.br

Not verifying emails at wisefour.com.br can lead to:

• High Bounce Rates: If you don't verify emails, your list will be outdated, and you'll risk seeing a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate.
• Risky Emails: Other services may leave most emails at wisefour.com.br as risky, so you don't know how to deal with them. If you keep the emails, you may risk seeing a high bounce; if you delete all of them, you risk missing potentially valuable valid emails.
