Verifying email addresses is an essential step in maintaining a healthy email list, especially when it comes to domains like twise.eu. In this blog post, we'll discuss the challenges of verifying emails at twise.eu, the risks of not doing so, and how BounceBan can help you verify catchall emails with high accuracy.

About twise.eu

TWISE is a human resources company based in Frankfurt, Hesse, Germany. With a domain like twise.eu, it's essential to ensure that email addresses are verified accurately to avoid bounces and maintain a good sending reputation.

Challenges of Verifying Emails at twise.eu

Verifying emails at twise.eu can be challenging due to several reasons:

• Catchall Emails: twise.eu is set to catchall, which means that traditional verification services may not be able to verify emails accurately. Catchall emails are email addresses that do not have a specific username, and instead, catch all emails sent to a particular domain.
• Email Security Gateways (ESG): twise.eu may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. These gateways can make simple SMTP tests fail, making it difficult to verify emails.
• No Bounce Messages: twise.eu may not always return a bounce message even if you send test messages to an invalid email address. This can make it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at twise.eu

Not verifying emails at twise.eu can lead to several risks, including:

• High Bounce Rate: If you don't verify emails, you may end up sending emails to invalid addresses, resulting in a high bounce rate. This can damage your sending reputation and lead to a lower delivery rate, open rate, and click rate.
• Outdated Email List: If you don't verify emails, your list will become outdated, leading to a high bounce rate and a damaged sending reputation.
• Risky Emails: Other services may leave most emails at twise.eu as risky, leaving you unsure of 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.
