Verifying Emails from tosi.cz: Challenges and Solutions

In today's digital age, email verification is a crucial step in maintaining a healthy email list and ensuring successful email marketing campaigns. However, verifying emails from certain domains can be a daunting task, especially when dealing with catchall emails. In this article, we'll discuss the challenges of verifying emails from tosi.cz and how BounceBan can help overcome these obstacles.

About tosi.cz

tosi.cz is a domain that presents unique challenges when it comes to email verification. With a catchall setup, tosi.cz receives all emails sent to non-existent addresses, making it difficult for traditional verification services to accurately verify email addresses.

Challenges of Verifying Emails at tosi.cz

Verifying emails at tosi.cz can be challenging due to several reasons:

• Email Security Gateways (ESG): There is a possibility that tosi.cz uses ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Setup: tosi.cz is set up as a catchall, which means that traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails accurately.
• No Bounce Messages: tosi.cz may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby ineffective.

Risks of Not Verifying Emails at tosi.cz

Not verifying emails at tosi.cz can lead to several risks:

• Risky Emails: Other services may leave most emails at tosi.cz as risky, leaving you unsure of how to handle them. If you keep the emails, you risk seeing a high bounce rate, and if you delete all of them, you risk missing potentially valuable valid emails.
• Outdated List: If you don't verify emails, your list will become outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately leading to lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
