Verifying email addresses is an essential step in maintaining a healthy email list and ensuring successful email campaigns. However, verifying catchall emails can be a significant challenge, especially when dealing with domains like tunnel.de. In this article, we will discuss the challenges of verifying emails at tunnel.de, the risks of not verifying them, and how BounceBan can help you overcome these challenges.
About tunnel.de
tunnel.de is a domain that may use email security gateways (ESG) to protect its email infrastructure, making it difficult for traditional verification services to verify email addresses accurately. Additionally, tunnel.de is set to catchall, which means that simple SMTP tests used by most verification services will not work. This is because catchall emails are not explicitly defined in the email infrastructure, making it hard to determine their validity.
Challenges of Verifying Emails at tunnel.de
Verifying emails at tunnel.de can be challenging due to several reasons:
- Email Security Gateways (ESG): tunnel.de may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
- Catchall Emails: tunnel.de is set to catchall, which means that traditional verification services cannot verify email addresses accurately.
- No Bounce Message: tunnel.de may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby not work.
Risks of Not Verifying Emails at tunnel.de
Not verifying emails at tunnel.de can lead to several risks, including:
- Outdated Email List: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and affecting your email delivery rate, open rate, and click rate.
- Risky Emails: Other services may leave most emails at tunnel.de as risky, making it difficult to decide what to do 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.
