Verifying email addresses is a crucial step in maintaining a healthy email list, especially when dealing with catchall emails. In this blog post, we'll discuss the challenges of verifying emails from tst.cz, a prominent company in the oil and energy industry, and how BounceBan can help you overcome these challenges.

About tst.cz

Teplarna Strakonice a.s. is a Czech-based company operating in the oil and energy sector. With its domain tst.cz, the company uses a catchall email system, which can make email verification a daunting task. The most common email pattern used by tst.cz is js@tst.cz, accounting for approximately 28% of their email addresses.

Challenges of Verifying Emails at tst.cz

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

• Email Security Gateways (ESG): tst.cz may use 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.
• Catchall Emails: tst.cz uses a catchall email system, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify these emails.
• No Bounce Messages: tst.cz 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 tst.cz

Failing to verify emails at tst.cz can result in:

• High Bounce Rates: If you don't verify emails, your list will be outdated, leading to a high bounce rate, which can damage your sending reputation, and as a result, lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email services providers may restrict your account.
• Risky Emails: Other services may leave most emails at tst.cz as risky, leaving you uncertain about how to deal with them. If you keep the emails, you may risk seeing a high bounce; if you delete all of them, you risk missing potentially valuable valid emails.
