As businesses grow, so do their email lists, and with that comes the challenge of verifying the authenticity of email addresses. This is especially crucial when dealing with domains like yondrgroup.com, where the risk of invalid or catchall emails can be high. In this blog post, we'll explore the challenges of verifying emails at yondrgroup.com and how BounceBan can help you overcome them.

About Yondr Group

Yondr Group is an information services company based in Amsterdam, North Holland, Netherlands. Their domain, yondrgroup.com, is a prime example of a domain that requires careful email verification to avoid bounces and maintain a healthy sending reputation.

Challenges of Verifying Emails at Yondr Group

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

• Email Security Gateways (ESG): It's unclear whether yondrgroup.com uses ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Emails: yondrgroup.com 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 work.
• No Bounce Messages: Even if you send test messages to an invalid email address at yondrgroup.com, it may not always return a bounce message, making services like Scrubby ineffective.

Risks of Not Verifying Emails at Yondr Group

Failing to verify emails at yondrgroup.com can lead to:

• High Bounce Rates: Unverified emails can result in high bounce rates, damaging your sending reputation and leading to lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at yondrgroup.com as risky, leaving you unsure of how to handle them. If you keep them, you risk a high bounce rate; if you delete them, you risk missing valuable valid emails.
