As a sales and marketing professional, you understand the importance of maintaining a clean and accurate email list. However, verifying email addresses from certain domains can be a daunting task. In this blog post, we'll explore the challenges of verifying emails at twenty1st.de, a financial consulting company based in Germany, and how BounceBan can help you overcome these challenges.
About twenty1st.de
twenty1st financial consulting GmbH is a financial consulting company based in Köln, North Rhine-Westphalia, Germany. The company operates in the legal services industry and uses the domain twenty1st.de for its email communications.
Challenges of Verifying Emails at twenty1st.de
Verifying emails at twenty1st.de can be challenging due to several reasons:
- Catchall Emails: twenty1st.de uses catchall emails, which means that a single email address can receive emails intended for multiple recipients. This makes it difficult for traditional email verification services to accurately verify email addresses.
- Email Security Gateways: There is a possibility that twenty1st.de uses 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 it difficult for simple SMTP tests to verify email addresses.
- No Bounce Messages: twenty1st.de may not always return a bounce message even if you send a test message to an invalid email address. This makes it difficult for services like Scrubby to verify email addresses.
Risks of Not Verifying Emails at twenty1st.de
If you don't verify emails at twenty1st.de, you risk:
- High Bounce Rates: If you don't verify email addresses, you may end up with a high bounce rate, which can damage your sending reputation and lead to lower delivery rates, open rates, and click rates.
- Outdated Lists: Failing to verify email addresses can result in outdated lists, which can lead to wasted resources and poor campaign performance.
- Restricted Accounts: If your bounce rate is too high, your email service provider may restrict your account.

Why BounceBan Stands Out
BounceBan is the only service capable of reliably verifying catchall emails and emails behind email security gateways. Other services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter are unable to verify catchall emails.
Approximately 40-50% of business emails are catchalls, which are not verifiable by other services. BounceBan, however, can accurately verify over 80% of these emails with a 97%+ accuracy rate. Catchall emails that cannot be verified with certainty will be tagged as 'risky', accounting for about 20% or less.
