Technologiezentrum Dortmund (tzdo.de) is a real estate company based in Dortmund, North Rhine-Westphalia, Germany. As a prominent player in the industry, they understand the importance of maintaining a clean and accurate email list. However, verifying emails from tzdo.de can be challenging due to its catchall email setup and potential use of Email Security Gateways (ESGs).
Challenges of Verifying Emails at tzdo.de
Verifying emails at tzdo.de is not an easy task. The domain uses a catchall email setup, which means that traditional email verification services may not be able to accurately verify emails. Moreover, tzdo.de may employ ESGs, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
Simple SMTP tests used by traditional verification services, like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter, may not be able to verify catchall emails at tzdo.de. Additionally, tzdo.de 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 at tzdo.de
Not verifying emails at tzdo.de can lead to several risks. Other services may leave most emails at tzdo.de as risky, making it difficult to determine how to handle them. If you keep the emails, you may risk seeing a high bounce rate, while deleting all of them may result in missing potentially valuable valid emails.
Moreover, if you don't verify emails, your list will be outdated, leading to a high bounce rate, which can damage your sending reputation. As a result, you may experience a lower delivery rate, open rate, and click rate. If the bounce rate is too high, your email service providers may restrict your account.

Why BounceBan Stands Out
BounceBan verifies over 80% of catchall emails with a 97%+ accuracy rate. Catchall emails that cannot be verified with certainty will be tagged as 'risky', accounting for about 20% or less. BounceBan's success rate in verifying catchall emails is on a consistent upward trajectory, verifying millions of emails daily and leveraging advanced AI to recognize patterns and enhance accuracy.
BounceBan verification is fast, taking only a few seconds for most emails. For a small share of catchall emails, it may take a few minutes. You can verify thousands of emails concurrently. Unlike Scrubby, BounceBan never has to actually send an email to verify the email, making it completely in compliance with GDPR.
