Introduction

Winner Administração de Patrimônio LTDA, a real estate company based in Rio de Janeiro, Brazil, uses the domain winneronline.com.br for their email communications. As a professional in the sales, marketing, AI, CRM, or B2B sectors, you may encounter the need to verify emails from this domain. However, verifying emails from winneronline.com.br can be challenging due to the domain's catchall setup and potential use of email security gateways.

Challenges of Verifying Emails at winneronline.com.br

Verifying emails from winneronline.com.br can be problematic due to several reasons:

• The domain may use email security gateways (ESG) such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• The domain is set to catchall, which means that traditional verification services may not be able to verify the emails.
• The domain may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails at winneronline.com.br

Not verifying emails from winneronline.com.br can lead to several risks:

• Other services may leave most emails at winneronline.com.br as risky, leaving you unsure of how to deal with them. If you keep the emails, you may risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
• If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately leading to lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
