Tunnelkom GmbH is a German-based company operating in the information technology and services industry. With its domain tunnelkom.de, the company uses a catchall email setup, which can make email verification challenging. In this blog post, we will discuss the challenges of verifying emails at tunnelkom.de, the risks of not verifying emails, and how BounceBan can help you verify emails from this domain reliably.
Challenges of Verifying Emails at tunnelkom.de
Verifying emails at tunnelkom.de can be tricky due to several reasons:
- Catchall Setup: tunnelkom.de uses a catchall email setup, which means that simple SMTP tests used by traditional verification services may not work. Catchall emails are emails that are not explicitly defined but still receive emails. This setup can make it difficult for verification services to determine whether an email is valid or not.
- Email Security Gateways (ESGs): There is a possibility that tunnelkom.de uses Email Security Gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. If this is the case, simple SMTP tests may fail, making verification even more challenging.
- No Bounce Messages: tunnelkom.de may not always return a bounce message even if you send a test message to an invalid email address. This can make it difficult for services like Scrubby to verify emails.
Risks of Not Verifying Emails at tunnelkom.de
Not verifying emails at tunnelkom.de can lead to several risks:
- High Bounce Rate: If you don't verify emails, your list may contain a high number of invalid emails, leading to a high bounce rate. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates.
- Wasted Resources: If you don't verify emails, you may end up sending emails to invalid addresses, wasting resources and potentially harming your brand reputation.
- Risky Emails: Other services may leave most emails at tunnelkom.de as risky, making it difficult to determine how to handle 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.
