As a professional in the telecommunications industry, you understand the importance of maintaining accurate and up-to-date email lists. One of the most significant challenges in email verification is dealing with catchall emails, which can be notoriously difficult to verify. In this blog post, we'll explore the challenges of verifying emails from wisi.es, a Spanish telecommunications company, and how BounceBan can help.

Understanding wisi.es

Wisi comunicaciones sa, a telecommunications company based in Madrid, Spain, uses the domain wisi.es for its email communications. With a significant proportion of its email addresses being catchall, traditional email verification services often struggle to accurately verify these emails.

Challenges of Verifying Emails from wisi.es

Verifying emails from wisi.es can be a daunting task due to several reasons:

• Catchall Emails: wisi.es uses catchall emails, which can be challenging to verify using traditional SMTP tests. Simple SMTP tests may fail to verify these emails, making it difficult to determine their validity.
• Email Security Gateways: There is a possibility that wisi.es uses email security gateways, such as Cisco Secure Email (ESA), Barracuda, or Proofpoint, which can block simple SMTP tests, making verification even more challenging.
• No Bounce Messages: wisi.es may not always return a bounce message when an invalid email address is sent a test message, making it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails from wisi.es

Failing to verify emails from wisi.es can lead to:

• High Bounce Rates: Unverified emails can result in high bounce rates, damaging your sending reputation and potentially leading to account restrictions.
• Outdated Lists: Failing to verify emails can lead to outdated lists, resulting in lower delivery rates, open rates, and click-through rates.
