As a business owner or marketer, you understand the importance of having a clean and accurate email list. One of the biggest challenges in email verification is dealing with catchall emails, which can be particularly tricky to verify. In this blog post, we'll discuss the challenges of verifying emails at tsf.io, a domain that poses unique verification challenges. We'll also explore how BounceBan can help you verify catchall emails from tsf.io with ease.

About tsf.io

tsf.io is a domain that uses a catchall email setup, which means that all emails sent to non-existent addresses within the domain are caught by a single email address. This setup can make it difficult for traditional email verification services to accurately verify email addresses.

Challenges of Verifying Emails at tsf.io

Verifying emails at tsf.io can be a daunting task due to several reasons:

• Email Security Gateways (ESG): tsf.io may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail. This makes it challenging for traditional verification services to accurately verify email addresses.
• Catchall Emails: tsf.io uses a catchall email setup, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work.
• No Bounce Messages: tsf.io 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 tsf.io

Not verifying emails at tsf.io can lead to several risks:

• High Bounce Rates: If you don't verify emails, your list may contain a high number of invalid addresses, leading to high bounce rates, damaging your sending reputation, and resulting in lower delivery rates, open rates, and click rates.
• Outdated Lists: Failing to verify emails can result in outdated lists, leading to wasted resources and poor campaign performance.
• Risky Emails: Leaving most emails at tsf.io as risky can lead to uncertainty about how to deal with them. If you keep the emails, you may risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
