As a business, verifying email addresses is crucial to maintaining a healthy email list and ensuring successful email campaigns. However, verifying emails from certain domains can be a challenge, especially when they are set to catchall or behind email security gateways. In this blog post, we'll discuss the challenges of verifying emails from yellowt.lu and how BounceBan can help.

About yellowt.lu

Yellowt.lu is a domain with a catchall setup, which means that all emails sent to non-existent addresses will be caught by a single mailbox. This setup can make it difficult for traditional email verification services to accurately verify email addresses. The most common email pattern used by yellowt.lu is smith.john@yellowt.lu, accounting for 20% of all email addresses.

Challenges of Verifying Emails from yellowt.lu

Verifying emails from yellowt.lu can be challenging due to several reasons:

• Catchall setup: Yellowt.lu's catchall setup makes it difficult for traditional email verification services to accurately verify email addresses. Simple SMTP tests used by traditional verification services may fail to verify emails behind a catchall setup.
• Email security gateways: There is a possibility that yellowt.lu uses 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 message: Yellowt.lu may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails from yellowt.lu

Not verifying emails from yellowt.lu can lead to:

• High bounce rates: If you don't verify emails, your list will be outdated, resulting in high bounce rates, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate.
• Risky emails: Other services may leave most emails at yellowt.lu as risky, leaving you unsure of how to deal with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
