About yello.cz
yello.cz is the domain of yello energy, a utilities company based in Prague, Czechia.

This makes it difficult for traditional email verification services to verify emails from this domain.
Challenges of Verifying Emails from yello.cz
Verifying emails from yello.cz can be challenging due to several reasons:
- Catchall emails: yello.cz uses a catchall email system, which means that simple SMTP tests used by traditional verification services may not work.
- Email Security Gateways: There is a possibility that yello.cz uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
- No bounce messages: Even if you send a test message to an invalid email address at yello.cz, it may not return a bounce message, making it difficult for services like Scrubby to verify emails.
Risks of Not Verifying Emails from yello.cz
Not verifying emails from yello.cz can lead to several risks:
- High bounce rate: If you don't verify emails, your list will be outdated, and you may risk seeing a high bounce rate, damaging your sending reputation and lowering your delivery rate, open rate, and click rate.

- Account restrictions: If your bounce rate is too high, your email service provider may restrict your account.
