As businesses continue to grow and expand, email verification becomes an essential step in maintaining a healthy email list. Wisper.io, a software development company based in France, is no exception. With a significant portion of its email addresses set as catchalls, verifying emails from this domain can be a challenge. In this blog post, we'll discuss the challenges of verifying emails from Wisper.io, the risks of not verifying them, and how BounceBan can help you verify these emails accurately.

Understanding Wisper.io

Wisper.io is a software development company based in Levallois-Perret, Île-de-France, France. The company uses a unique email pattern distribution, with the most common pattern being j.smith@wisper.io (30%). Other common patterns include john.smith@wisper.io (22%), john.smith@wisper.io (10%), and johns@wisper.io (5%). Wisper.io's email domain is set as a catchall, which means that any email sent to a non-existent email address at this domain will not bounce.

Challenges of Verifying Emails from Wisper.io

Verifying emails from Wisper.io can be challenging due to several reasons:

• Catchall Domain: Wisper.io's email domain is set as a catchall, which means that simple SMTP tests used by traditional verification services may not work.
• Email Security Gateways: Wisper.io may use email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• No Bounce Messages: Wisper.io 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 from Wisper.io

Not verifying emails from Wisper.io 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• High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate.
• Risky Emails: Leaving most emails at Wisper.io as risky means you don't 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.
