About up-systemhaus.de
U P Systemhaus GmbH is a German company based in Cologne, North Rhine-Westphalia, Germany. The company operates in the information technology and services industry. Their email domain is up-systemhaus.de, and they use a catchall email setup.
Challenges of Verifying Emails from up-systemhaus.de
Verifying emails from up-systemhaus.de can be challenging due to several reasons:
- Catchall Emails: up-systemhaus.de uses a catchall email setup, which means that simple SMTP tests used by traditional verification services may not work. Catchall emails are not verifiable by services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter.
- Email Security Gateways: It's unclear whether up-systemhaus.de uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it can make simple SMTP tests fail.
- No Bounce Messages: up-systemhaus.de may not always return a bounce message even if you send a test message to an invalid email address. This makes services like Scrubby, which verify emails by sending test messages, ineffective.
Risks of Not Verifying Emails from up-systemhaus.de
Not verifying emails from up-systemhaus.de can lead to several risks:
- High Bounce Rates: If you don't verify emails, you may end up with a high bounce rate, damaging your sending reputation and resulting in lower delivery rates, open rates, and click rates.
- Outdated Lists: Without verification, your email list will become outdated, leading to wasted resources and potential revenue loss.
- Risky Emails: Leaving most emails at up-systemhaus.de as risky can lead to uncertainty about how to handle them. If you keep them, you risk seeing a high bounce rate; if you delete them, you risk missing potentially valuable valid emails.
