As businesses increasingly rely on email marketing and sales, the importance of verifying email addresses cannot be overstated. However, some domains pose unique challenges when it comes to email verification. In this blog post, we'll explore the challenges of verifying emails from tsun-ess.com and how BounceBan can help overcome these challenges.
About tsun-ess.com

With a commitment to building a top global energy storage brand, Tsun's innovative approach has earned it a reputation in the semiconductors industry.

Challenges of Verifying Emails at tsun-ess.com
Verifying emails at tsun-ess.com can be challenging due to several reasons:
- Catchall Emails: tsun-ess.com is set up as a catchall domain, which means that simple SMTP tests used by traditional verification services may not work. Catchall emails are designed to catch all emails sent to non-existent addresses, making it difficult to determine whether an email is valid or not.
- Email Security Gateways: tsun-ess.com may use email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. These gateways can make simple SMTP tests fail, making it even harder to verify emails.
- No Bounce Messages: Even if you send test messages to an invalid email address at tsun-ess.com, it may not always return a bounce message. This makes services like Scrubby, which rely on sending emails to verify them, ineffective.
Risks of Not Verifying Emails at tsun-ess.com
Not verifying emails at tsun-ess.com can lead to several risks:
- High Bounce Rates: If you don't verify emails, your list may be outdated, resulting in high bounce rates. This can damage your sending reputation, leading to lower delivery rates, open rates, and click rates.
- Missing Valuable Emails: If you delete all unverified emails, you may miss potentially valuable contacts.
- Account Restrictions: If your bounce rate is too high, your email service providers may restrict your account.
