As one of Germany's largest and most internationally renowned technical universities, Technische Universität Berlin (TU Berlin) is a hub for innovation and knowledge. With almost 34,000 students and 100 course offerings, the university's email domain, tu.berlin, is an essential part of its communication infrastructure. However, verifying emails from this domain can be a challenge, especially when it comes to catchall and risky emails.
Challenges of Verifying Emails at tu.berlin
Verifying emails from tu.berlin can be tricky due to several reasons:
- Catchall Emails: tu.berlin is set to catchall, which means that simple SMTP tests used by traditional verification services may not be able to verify these emails. Catchall emails are a significant challenge, as they can account for up to 40-50% of business emails.
- Email Security Gateways (ESGs): tu.berlin may use ESGs, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail.
- No Bounce Messages: tu.berlin 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 tu.berlin
Not verifying emails at tu.berlin can lead to several risks, including:
- High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates.
- Missed Opportunities: Deleting all unverified emails can result in missing potentially valuable contacts.
- Account Restrictions: If the bounce rate is too high, your email service providers may restrict your account.
