Introduction
In today's digital age, verifying email addresses is crucial for businesses to maintain a healthy email list and prevent bounces. However, verifying catchall emails from certain domains can be challenging. In this blog post, we will discuss the challenges of verifying emails from ys-sys.co.jp and how BounceBan can help.
About ys-sys.co.jp
ys-sys.co.jp is a Japanese company with a unique domain setup. According to our research, the domain is set to catchall, which means that any email address that does not exist will still be accepted by the server. This setup can make it difficult for traditional email verification services to verify emails from this domain.
Challenges of Verifying Emails from ys-sys.co.jp
Verifying emails from ys-sys.co.jp can be challenging due to several reasons:
- Email Security Gateways (ESG): There is no information available on whether ys-sys.co.jp uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it will make it difficult for traditional verification services to verify emails.
- Catchall Setup: The domain is set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter will not work.
- No Bounce Message: Even if you send test messages to an invalid email address at ys-sys.co.jp, the domain may not always return a bounce message, making services like Scrubby not work.
Risks of Not Verifying Emails from ys-sys.co.jp
Not verifying emails from ys-sys.co.jp can lead to several risks:
- High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate.
- Risky Emails: Other services may leave most emails at ys-sys.co.jp as risky, leaving you unsure of how to deal with them. If you keep the emails, you may risk seeing a high bounce; if you delete all of them, you risk missing potentially valuable valid emails.
