As a marketer, salesperson, or CRM professional, you understand the importance of maintaining a clean and accurate email list. However, verifying email addresses from certain domains can be a daunting task, especially when dealing with catchall emails. In this blog post, we'll explore the challenges of verifying emails from zestan.com, a marketing and advertising company based in Barcelona, Catalonia, Spain.
About Zestan.com
Zestan.com is a domain used by Zestan S.A., a company operating in the marketing and advertising industry. With a significant presence in Spain, the company relies heavily on email communication, making email verification a crucial aspect of their operations.
Challenges of Verifying Emails at Zestan.com
Verifying emails from zestan.com can be challenging due to several reasons:
- Catchall Emails: Zestan.com uses catchall emails, which can be difficult to verify using traditional verification services. Catchall emails are set up to receive all emails sent to a specific domain, making it hard to determine whether an email is valid or not.
- Email Security Gateways: There is no information available on whether zestan.com uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos. If they do, it can make simple SMTP tests fail, making verification even more challenging.
- No Bounce Messages: Zestan.com may not always return a bounce message even if you send a test message to an invalid email address. This makes it difficult for services like Scrubby to verify emails.
Risks of Not Verifying Emails at Zestan.com
Failing to verify emails from zestan.com can lead to:
- High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation and lowering delivery rates, open rates, and click rates.
- Risky Emails: Other services may leave most emails at zestan.com as risky, leaving you unsure of how to handle 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.
