Challenges of Verifying Emails at withub.org

Verifying emails at withub.org can be challenging due to several reasons:

• Catchall Emails: Withub.org uses catchall emails, which can be difficult to verify using traditional methods. Catchall emails are emails that are not explicitly assigned to a specific user, making it hard to determine their validity.
• Email Security Gateways: There is no information about whether withub.org uses email security gateways (ESG) to filter out unwanted emails. If they do, it could make simple SMTP tests fail, making verification even more challenging.
• Lack of Bounce Messages: Withub.org may not always return a bounce message even if you send a test message to an invalid email address, making it difficult to determine the validity of an email.

Risks of Not Verifying Emails at withub.org

Not verifying emails at withub.org 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• High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate.
• Risky Emails: Other services may leave most emails at withub.org as risky, leaving you unsure of how to deal with them. If you keep the emails, you risk seeing a high bounce; if you delete all of them, you risk missing potentially valuable valid emails.
