Verifying email addresses is an essential step in maintaining a healthy email list, especially when dealing with domains that use catchall emails or email security gateways (ESGs). In this blog post, we'll explore the challenges of verifying emails at zelcos.com, a cosmetics company based in Penang, Malaysia, and how BounceBan can help overcome these challenges.
About Zelcos.com
Zelcos Laboratory Sdn Bhd is a cosmetics company operating in Penang, Malaysia. The company uses the domain zelcos.com, which has a catchall email setup. This means that any email address not explicitly defined will be caught by the catchall email account. The most common email pattern used by the company is smithj@zelcos.com (26%), followed by john.smith@zelcos.com (9%).
Challenges of Verifying Emails at Zelcos.com
Verifying emails at zelcos.com can be challenging due to several reasons:
- Catchall Emails: Zelcos.com uses a catchall email setup, which can make it difficult for traditional email verification services to verify emails. Catchall emails are not explicitly defined, making it hard to determine whether an email address is valid or not.
- Email Security Gateways (ESGs): There is a possibility that zelcos.com uses ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
- Lack of Bounce Messages: Even if you send test messages to an invalid email address at zelcos.com, the domain may not always return a bounce message, making it difficult for services like Scrubby to verify emails.
Risks of Not Verifying Emails at Zelcos.com
Not verifying emails at zelcos.com can lead to several risks, including:
- High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate.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 zelcos.com as risky, making it difficult to determine how to deal with them. If you keep the emails, you risk seeing a high bounce rate, and if you delete them, you risk missing potentially valuable valid emails.
