Introduction to Upstairs.nl

Upstairs.nl is a prominent company in its industry, with a strong online presence. As a responsible sender, it's essential to ensure the accuracy of email addresses in your database, especially when dealing with a domain like upstairs.nl, which has catchall email setup.

Challenges of Verifying Emails at Upstairs.nl

Verifying emails at upstairs.nl can be a daunting task due to several reasons:

• Email Security Gateways (ESG): Although there is no concrete evidence, it's possible that upstairs.nl employs email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Emails: Upstairs.nl has a catchall email setup, which means that traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify these emails accurately.
• Lack of Bounce Messages: Upstairs.nl may not always return a bounce message even when sending test messages to invalid email addresses, making services like Scrubby ineffective.

Failing to verify emails at upstairs.nl can lead to:

• High Bounce Rates: Leaving most emails as "risky" can result in a high bounce rate, damaging your sending reputation and lowering delivery rates, open rates, and click rates.
