As a business, having accurate and reliable email verification is crucial for maintaining a healthy email list and avoiding high bounce rates. However, verifying emails from certain domains can be challenging, especially when dealing with catchall emails and email security gateways. In this blog post, we'll discuss the challenges of verifying emails from zennon.de and how BounceBan can help overcome these challenges.
About zennon.de
Zennon is a company based in Hong Kong, with a domain name of zennon.de. Their email domain is set up to catchall, which means that it accepts all emails sent to it, regardless of whether the email address exists or not. This setup can make it difficult to verify email addresses using traditional methods.
Challenges of Verifying Emails at zennon.de
Verifying emails at zennon.de can be challenging due to several reasons:
- Email Security Gateways: There is no information on whether zennon.de uses email security gateways (ESG) such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos. If they do, it may make simple SMTP tests fail, making it difficult to verify emails.
- Catchall Emails: Since zennon.de is set up to catchall, 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 zennon.de, it may not always return a bounce message, making services like Scrubby not work.
Risks of Not Verifying Emails at zennon.de
Not verifying emails at zennon.de can lead to several risks:
- Risky Emails: Other services may leave most emails at zennon.de as risky, leaving you unsure of how to deal with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
- Outdated List: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately leading to a lower delivery rate, open rate, and click rate. If the bounce rate is too high, your email service providers may restrict your account.
