Challenges of Verifying Emails from tjoa.nl

Verifying email addresses from tjoa.nl can be challenging due to several reasons:

• Catchall Emails: tjoa.nl is set up as a catchall domain, which means that simple SMTP tests used by traditional verification services may not work. Catchall emails are designed to capture all emails sent to non-existent addresses, making it difficult to determine whether an email is valid or not.
• Email Security Gateways: There is no information yet about whether tjoa.nl uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it would make simple SMTP tests fail, adding another layer of complexity to the verification process.
• No Bounce Messages: tjoa.nl may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby ineffective.

Risks of Not Verifying Emails from tjoa.nl

Not verifying email addresses from tjoa.nl can lead to several risks:

• Risky Emails: Other services may leave most emails at tjoa.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• Outdated Lists and High Bounce Rates: If you don't verify emails, your list will become outdated, resulting in high bounce rates, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
