Verifying emails from yack.com.br can be a daunting task, especially when dealing with catchall emails. In this blog post, we will explore the challenges of verifying emails from yack.com.br and how BounceBan can help overcome these challenges.

About yack.com.br

yack.com.br is a Brazilian company operating in the information technology and services industry. Their domain, yack.com.br, has a catchall setup, which means that emails sent to non-existent addresses may not bounce back. This setup can make it difficult to verify email addresses using traditional verification methods.

Challenges of Verifying Emails from yack.com.br

Verifying emails from yack.com.br can be challenging due to several reasons:

• Email Security Gateways: yack.com.br may use email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
• Catchall Emails: yack.com.br has a catchall setup, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work.
• No Bounce Messages: yack.com.br 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 from yack.com.br

Not verifying emails from yack.com.br can lead to:

• High Bounce Rates: If you don't verify emails, your list will be outdated, and you may risk seeing a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate.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 yack.com.br as risky, so you don't know how to deal with it - 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.
