As a business, having accurate and reliable email verification is crucial for maintaining a healthy email list and avoiding bounces. However, verifying emails from certain domains can be a challenge, especially when it comes to catchall emails. In this blog post, we'll explore the challenges of verifying emails at umbra.nl, a Dutch company, and how BounceBan can help overcome these obstacles.

About umbra.nl

Umbra.nl is a Dutch company operating in the [industry] sector. With its domain umbra.nl, the company uses a catchall email system, which means that all emails sent to non-existent addresses within the domain will be caught by a single email account. This can make email verification more complex.

Challenges of Verifying Emails at umbra.nl

Verifying emails at umbra.nl can be challenging due to several reasons:

• Catchall Emails: umbra.nl uses a catchall email system, which makes it difficult for traditional verification services to verify emails. Simple SMTP tests used by services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work, as they can't distinguish between valid and invalid emails.
• Email Security Gateways: There is a possibility that umbra.nl uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. These gateways can make simple SMTP tests fail, making email verification even more challenging.
• No Bounce Messages: umbra.nl may not always return a bounce message even if you send test messages to an invalid email address at that domain. This can make it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at umbra.nl

Not verifying emails at umbra.nl can lead to several risks:

• High Bounce Rates: If you don't verify emails, your list may contain invalid or non-existent addresses, leading to high bounce rates. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates.
• Outdated Lists: Failing to verify emails can lead to outdated lists, which can negatively impact your email marketing campaigns.
• Risky Emails: Other services may leave most emails at umbra.nl as risky, making it difficult to determine which emails to keep or delete. This can result in missed opportunities or high bounce rates.
