Topdeuren.nl is a prominent company in the construction industry, based in Barneveld, Gelderland, Netherlands. As a leading business in its sector, it's essential for Topdeuren.nl to maintain a clean and accurate email list to ensure effective communication with customers, partners, and suppliers. However, verifying email addresses at Topdeuren.nl can be a challenging task, especially when dealing with catchall emails.

The Challenge of Verifying Emails at Topdeuren.nl

Verifying emails at Topdeuren.nl can be difficult due to several reasons:

• Email Security Gateways (ESG): Topdeuren.nl may use 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.
• Catchall Emails: Topdeuren.nl is set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter cannot verify these emails.
• No Bounce Messages: Even if you send test messages to an invalid email address at Topdeuren.nl, it may not always return a bounce message, making services like Scrubby ineffective.

The Risks of Not Verifying Emails at Topdeuren.nl

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

• High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, which can damage your sending reputation and lead to lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at Topdeuren.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.
