As a sales or marketing professional, you understand the importance of maintaining a clean and accurate email list. However, verifying emails from certain domains can be a daunting task, especially when it comes to catchall emails. In this blog post, we'll explore the challenges of verifying emails from Zest.co, a company in the information technology and services industry, and how BounceBan can help you overcome these challenges.

About Zest.co

Zest.co is a company based in New York, United States, and operates in the information technology and services industry. With its domain zest.co, the company uses a catchall email setup, which can make email verification a challenge.

Challenges of Verifying Emails from Zest.co

Verifying emails from Zest.co can be difficult due to several reasons:

• Catchall Email Setup: Zest.co uses a catchall email setup, which means that any email sent to a non-existent email address at zest.co will not bounce back. This makes it difficult for traditional email verification services to determine the validity of an email address.
• Email Security Gateways: Zest.co may use email security gateways such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can block simple SMTP tests used by traditional verification services.
• No Bounce Messages: Zest.co may not always return a bounce message even if you send a test message to an invalid email address, making it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails from Zest.co

Not verifying emails from Zest.co can lead to several risks, including:

• High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate.
• Risky Emails: Other services may leave most emails at zest.co as risky, leaving you unsure of how to deal with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
