Challenges of Verifying Emails at umain.co.kr

Verifying email addresses at umain.co.kr can be challenging due to several reasons:

• Catchall Emails: umain.co.kr uses catchall email settings, which means that a single email address can receive emails intended for multiple recipients. Traditional email verification services may not be able to verify these emails accurately.
• Email Security Gateways (ESGs): There is no information yet about whether umain.co.kr uses ESGs to filter out unwanted emails. If they do, it can make simple SMTP tests used by traditional verification services fail.
• No Bounce Messages: umain.co.kr may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails at umain.co.kr

Not verifying email addresses at umain.co.kr can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, you may end up with a high bounce rate, which can damage your sending reputation and lead to lower delivery rates, open rates, and click rates.
• Outdated Lists: Failing to verify emails can result in outdated lists, which can lead to wasted resources and poor campaign performance.
• Risky Emails: Other services may leave most emails at umain.co.kr as risky, leaving you unsure of how to deal with them. If you keep them, you risk seeing a high bounce rate, and if you delete them, you risk missing potentially valuable valid emails.
