Challenges of Verifying Emails at Wynca.com
Verifying emails at wynca.com can be challenging due to several reasons:
- Wynca.com may use Email Security Gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
- The domain may be set to catchall, making traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter ineffective.
- Wynca.com may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby not work.
Risks of Not Verifying Emails at Wynca.com
Not verifying emails at wynca.com can lead to several risks:
- Other services may leave most emails at wynca.com 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.
- If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and subsequently, lower delivery rate, open rate, and click rate. If the bounce rate is too high, your email services providers may restrict your account.

Why BounceBan?
BounceBan is the only service that can accurately verify catchall emails and emails behind Email Security Gateways. Services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter are unable to verify catchall emails. Approximately 40-50% (increasing overtime) of business emails are catchalls, which are not verifiable by other services. BounceBan, however, can accurately verify over 80% of these emails with a 97%+ accuracy rate. Catchall emails that cannot be verified with certainty will be tagged as 'risky', accounting for about 20% or less.
