Verifying email addresses is an essential step in maintaining a healthy email list and ensuring successful email campaigns. However, verifying catchall emails can be a daunting task, especially when dealing with domains like tonderksen.nl. In this article, we'll explore the challenges of verifying emails at tonderksen.nl, the risks of not verifying them, and how BounceBan can help you overcome these challenges.

About tonderksen.nl

tonderksen.nl is a domain that poses unique challenges when it comes to verifying email addresses. With its catchall email setup, traditional verification services often struggle to accurately verify email addresses. The domain's email pattern distribution is diverse, with the most common pattern being john.s@tonderksen.nl (27%), followed by j-smith@tonderksen.nl (14%), john_smith@tonderksen.nl (14%), and smithj@tonderksen.nl (7%).

Challenges of Verifying Emails at tonderksen.nl

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

• Email Security Gateways (ESGs): tonderksen.nl may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail. This means that traditional verification services may not be able to verify emails accurately.
• Catchall Emails: tonderksen.nl is set up as a catchall domain, which means that simple SMTP tests used by traditional verification services may not work. This is because catchall emails do not return a bounce message even when the email address is invalid.
• No Bounce Messages: Even when sending test messages to an invalid email address at tonderksen.nl, the domain may not always return a bounce message. This makes it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at tonderksen.nl

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

• High Bounce Rates: If you don't verify emails, you may end up with a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate.
• Outdated Lists: Failing to verify emails can result in outdated lists, leading to wasted resources and poor campaign performance.
• Risky Emails: Other services may leave most emails at tonderksen.nl as risky, making it difficult to decide what to do with them. If you keep them, you risk seeing a high bounce rate; if you delete them, you risk missing potentially valuable valid emails.
