Verifying email addresses is a crucial step in maintaining a healthy and accurate email list, especially when it comes to businesses like UNN Online, a prominent player in the advertising services industry. With its domain, unn-online.de, and a significant portion of catchall emails, verifying email addresses can be a daunting task. In this blog post, we'll delve into the challenges of verifying emails at UNN Online, the risks of not doing so, and how BounceBan can help overcome these hurdles.

UNN Online is a leading advertising services company based in Karlsruhe, Germany. With its strong presence in the industry, the company has built a reputation for providing top-notch advertising solutions to its clients. As a business, UNN Online relies heavily on effective communication, making email verification a critical aspect of its operations.
The Challenges of Verifying Emails at UNN Online
Verifying email addresses at UNN Online can be challenging due to several reasons:
- Catchall Emails: UNN Online's domain,
unn-online.de, is set to catchall, which means that traditional verification services may not be able to verify emails accurately. Catchall emails are a common practice in many businesses, and approximately 40-50% of business emails are catchalls, which are not verifiable by other services. - Email Security Gateways (ESGs): There is no information yet about whether UNN Online uses ESGs, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it would make simple SMTP tests fail, adding another layer of complexity to email verification.
- Lack of Bounce Messages: UNN Online may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby not work.
The Risks of Not Verifying Emails at UNN Online
Not verifying email addresses at UNN Online can lead to several risks, including:
- High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lowering your delivery rate, open rate, and click rate.
- Risky Emails: Other services may leave most emails at UNN Online as risky, leaving you unsure of 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.
- Account Restrictions: If the bounce rate is too high, your email service providers may restrict your account, affecting your business operations.
