Verifying email addresses is an essential step in maintaining a healthy email list, especially when dealing with catchall emails. In this blog post, we'll explore the challenges of verifying emails from tonslosser.nl, a Dutch company specializing in insurance and mortgages, and how BounceBan can help overcome these challenges.

About tonslosser.nl

tonslosser.nl is the domain of Slosser Verzekeringen & Hypotheken BV, a company operating in the banking industry in the Netherlands. With a catchall email domain, tonslosser.nl poses unique challenges when it comes to verifying email addresses.

Challenges of Verifying Emails at tonslosser.nl

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

• Catchall Email Domain: tonslosser.nl is a catchall email domain, which means that simple SMTP tests used by traditional verification services may not work. This is because catchall domains are designed to catch all emails sent to a specific domain, regardless of whether the email address exists or not.
• Email Security Gateways (ESG): tonslosser.nl may be using email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail. If tonslosser.nl uses an ESG, it will be a significant challenge for traditional verification services.
• No Bounce Message: tonslosser.nl may not always return a bounce message even if you send test messages to an invalid email address at that domain, making services like Scrubby not work.

Risks of Not Verifying Emails at tonslosser.nl

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

• High Bounce Rate: If you don't verify emails, your list will be outdated, and you may experience a high bounce rate, damaging your sending reputation. This can result in lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email services providers may restrict your account.
• Risky Emails: Other services may leave most emails at tonslosser.nl as risky, so you don't know 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.
