As businesses rely more heavily on email marketing and sales outreach, the importance of verifying email addresses has become increasingly crucial. One domain that presents unique challenges in email verification is wltr.nl. In this blog post, we'll delve into the specifics of wltr.nl, the challenges of verifying emails from this domain, and how BounceBan can help overcome these challenges.

Understanding wltr.nl

wltr.nl is a domain with a unique email pattern distribution. The most common email pattern is john.smith@wltr.nl, accounting for 27% of all email addresses. The domain is set to catchall, which means that it can receive emails even if the email address does not exist. This catchall setup can make email verification more complex.

Challenges of Verifying Emails at wltr.nl

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

• Email Security Gateways: wltr.nl may use 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: wltr.nl is set to catchall, which means that simple SMTP tests used by traditional verification services may not work.
• No Bounce Messages: wltr.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 at wltr.nl

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

• Risky Emails: Other services may leave most emails at wltr.nl as risky, leaving you unsure of how to deal with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
• Outdated Lists: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate. If the bounce rate is too high, your email service providers may restrict your account.
