As a business entity, maintaining a clean and accurate email list is crucial for effective communication and successful marketing campaigns. However, verifying email addresses, especially those from specific domains like usina.biz, can be a daunting task. In this blog post, we will discuss the challenges of verifying emails from usina.biz, the risks of not verifying them, and how BounceBan can help you overcome these obstacles.

About USINA - Business Craft Factory ®

USINA - Business Craft Factory ® is a management consulting firm based in São Paulo, Brazil. The company operates under the domain usina.biz, which is a catchall domain. This means that the domain is set to receive all emails addressed to it, even if the email address does not exist.

Challenges of Verifying Emails from usina.biz

Verifying email addresses from usina.biz can be challenging due to several reasons:

• Email Security Gateways (ESG): There is no information yet about whether usina.biz uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If it does, traditional verification services may fail to verify emails from this domain.
• Catchall Domain: As mentioned earlier, usina.biz is a catchall domain, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails from this domain.
• No Bounce Message: Even if you send test messages to an invalid email address at usina.biz, the domain may not always return a bounce message, making services like Scrubby ineffective.

Risks of Not Verifying Emails from usina.biz

Not verifying emails from usina.biz can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, which can damage your sending reputation and lead to lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email services providers may restrict your account.
• Risky Emails: Other services may leave most emails at usina.biz 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.
