Challenges of Verifying Emails from wonderfour.se

Verifying emails from wonderfour.se can be challenging due to several reasons:

• Catchall Emails: wonderfour.se uses a catchall email setup, which means that simple SMTP tests used by traditional verification services may not work. Catchall emails are a significant challenge, with approximately 40-50% of business emails being catchalls.
• Email Security Gateways: There is no information about whether wonderfour.se uses email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos. If they do, it could make simple SMTP tests fail.
• No Bounce Message: wonderfour.se 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

Not verifying emails from wonderfour.se can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list may be outdated, resulting in a high bounce rate, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate.
• Missing Valuable Emails: If you delete all unverified emails, you may miss potentially valuable contacts.
