Verifying email addresses from troef.nu can be a challenging task, especially when dealing with catchall emails. In this blog post, we will discuss the challenges of verifying emails from troef.nu, the risks of not verifying them, and how to use BounceBan to reliably verify catchall emails from this domain.

Basic Information about troef.nu

troef.nu is a domain used by a company in the industry. The company's email domain is set to catchall, which means that it may accept emails sent to non-existent addresses. The most common email pattern used by the company is j.smith@troef.nu, which accounts for 29% of all email addresses.

Challenges of Verifying Emails at troef.nu

Verifying emails at troef.nu can be challenging due to several reasons:

• Email Security Gateways (ESG): troef.nu may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. These gateways can make simple SMTP tests fail, making it difficult for traditional verification services to verify emails.
• Catchall Emails: Since troef.nu is set to catchall, simple SMTP tests used by traditional verification services may not be able to verify emails. This is because catchall emails do not return a bounce message even if the email address is invalid.
• No Bounce Message: troef.nu may not always return a bounce message even if you send a test message to an invalid email address. This makes it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at troef.nu

Not verifying emails at troef.nu can lead to several risks, including:

• High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate. This can damage your sending reputation, leading to lower delivery rates, open rates, and click rates.
• Restricted Account: If the bounce rate is too high, your email service providers may restrict your account.
• Risky Emails: Other services may leave most emails at troef.nu as risky, making it difficult to know how to deal with them. If you keep the emails, you may risk seeing a high bounce rate. If you delete all of them, you risk missing potentially valuable valid emails.
