The Challenge of Verifying Emails at Userbase.co

Verifying emails at Userbase.co can be a daunting task due to several reasons. Firstly, the domain may be set to catchall, which means that simple SMTP tests used by traditional verification services will fail. Catchall emails are email addresses that are not explicitly defined but are still accepted by the mail server. This makes it difficult for most email verification services to accurately verify emails from Userbase.co.

Another challenge is that Userbase.co may use email security gateways (ESG) such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail. Additionally, Userbase.co may not always return a bounce message even if you send test messages to an invalid email address at that domain, making services like Scrubby not work.

The Risks of Not Verifying Emails at Userbase.co

Not verifying emails at Userbase.co can lead to several risks. Other services may leave most emails at Userbase.co as risky, making it difficult to know how to deal with them. If you keep the emails, you may risk seeing a high bounce rate, which can damage your sending reputation and result in a lower delivery rate, open rate, and click rate. If the bounce rate is too high, your email service providers may restrict your account.
