Introduction to usifer.com.br

usifer.com.br is a Brazilian company operating in the industry. With its base in Brazil, usifer.com.br has established itself as a prominent player in the market. However, when it comes to email verification, usifer.com.br poses some unique challenges.

Challenges of Verifying Emails at usifer.com.br

Verifying emails at usifer.com.br can be a daunting task. Firstly, there is no information yet on whether usifer.com.br uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If it does, it will be a significant challenge for traditional verification services.

Another challenge is that usifer.com.br may be set to catchall, which means simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter will not be able to verify emails. Moreover, usifer.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 ineffective.

Risks of Not Verifying Emails at usifer.com.br

Not verifying emails at usifer.com.br can lead to several risks. Other services may leave most emails at usifer.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, and 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If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate. If the bounce rate is too high, your email services providers may restrict your account.
