Verifying emails is a crucial step in maintaining a healthy email list, especially when dealing with domains like topag.de that have catchall email configurations. In this article, we'll delve into the challenges of verifying emails at topag.de, the risks of not doing so, and how BounceBan can help you accurately verify emails from this domain.

About Topag.de

Topag Lasertechnik GmbH is a research company based in Darmstadt, Hesse, Germany. Their domain, topag.de, has a catchall email configuration, which means that they can receive emails sent to non-existent addresses. This can make it challenging to verify email addresses from this domain.

Challenges of Verifying Emails at Topag.de

Verifying emails at topag.de can be a daunting task due to several reasons:

• Catchall Email Configuration: Topag.de has a catchall email configuration, which means that simple SMTP tests used by traditional verification services may not work. These services may flag valid emails as invalid or vice versa.
• Email Security Gateways: Topag.de may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
• No Bounce Messages: Topag.de may not always return a bounce message even if you send test messages to an invalid email address at that domain. This can make it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at Topag.de

Not verifying emails at topag.de can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, your list may contain invalid or non-existent addresses, leading to high bounce rates. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates.
• Outdated Lists: Failing to verify emails can lead to outdated lists, which can result in wasted resources and poor campaign performance.
• Risky Emails: Other services may leave most emails at topag.de as risky, leaving you unsure of how to deal with them. If you keep them, you risk seeing a high bounce rate; if you delete them, you risk missing potentially valuable valid emails.
