Threewise.nl is a prominent education management company based in the Netherlands. As a professional in the sales, marketing, AI, CRM, or B2B sector, you may have encountered the need to verify email addresses from this domain. However, verifying emails at threewise.nl can be a challenging task due to its catchall email setup and potential use of email security gateways (ESG). In this blog post, we will discuss the challenges of verifying emails at threewise.nl, the risks of not verifying them, and how to use BounceBan to verify individual and bulk emails from this domain.

Challenges of Verifying Emails at threewise.nl

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

• Catchall Email Setup: Threewise.nl uses a catchall email setup, which means that it may accept all emails sent to its domain, regardless of whether they are valid or not. This setup makes it difficult for traditional email verification services to verify emails accurately.
• Email Security Gateways (ESG): Threewise.nl may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos to filter out spam and malicious emails. These gateways can make it difficult for email verification services to verify emails using simple SMTP tests.
• No Bounce Message: Threewise.nl may not always return a bounce message even if you send a test email to an invalid email address at its domain. This makes it challenging for services like Scrubby to verify emails accurately.

Risks of Not Verifying Emails at threewise.nl

Not verifying emails at threewise.nl can lead to several risks, including:

• High Bounce Rate: If you don't verify emails, your email list may contain a high percentage of invalid or non-existent email addresses, leading to a high bounce rate. This can damage your sending reputation and result in lower delivery rates, open rates, and click rates.
• Risky Emails: Other email verification services may leave most emails at threewise.nl as "risky" or "unknown," making it difficult for you to decide what to do with them. If you keep these emails, you may risk seeing a high bounce rate; if you delete them, you may miss potentially valuable valid emails.
• Outdated Email List: If you don't verify emails regularly, your email list may become outdated, leading to a high bounce rate and damaging your sending reputation.
