Verifying emails from zker.nl can be a daunting task, especially when dealing with catchall emails and email security gateways. In this blog post, we will discuss the challenges of verifying emails from zker.nl, the risks of not verifying emails, and how BounceBan can help you overcome these challenges.

Understanding zker.nl

ZKER is a civil engineering company based in Capelle aan den IJssel, South Holland, Netherlands. The company's email domain is zker.nl, and it uses a catchall email setup. The most common email pattern is js@zker.nl (26%), followed by john.s@zker.nl (24%), smith.john@zker.nl (11%), and johnsmith@zker.nl (6%). The company's MX records are zker-nl.mail.protection.outlook.com.

Challenges of Verifying Emails from zker.nl

Verifying emails from zker.nl can be challenging due to several reasons:

• Email Security Gateways: zker.nl may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. These gateways can make simple SMTP tests fail, making it difficult to verify emails.
• Catchall Emails: zker.nl uses a catchall email setup, which means that simple SMTP tests used by traditional verification services may not work. Services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify catchall emails.
• No Bounce Message: zker.nl 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 from zker.nl

Not verifying emails from zker.nl can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate.
• Risky Emails: Other services may leave most emails at zker.nl 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.
