Introduction

usrab.com is a domain that poses unique challenges when it comes to verifying email addresses. In this blog post, we will explore the difficulties of verifying emails from this domain and how BounceBan can help overcome these challenges.

Understanding usrab.com

usrab.com is a domain that has a catchall email setup, which means that all emails sent to non-existent addresses within the domain will still be accepted by the mail server. This setup can make it difficult for traditional email verification services to accurately verify email addresses.

The most common email pattern used by usrab.com is johnsmith@usrab.com, which accounts for about 19% of all email addresses. Other common patterns include j.smith@usrab.com (17%), johns@usrab.com (15%), and smith.john@usrab.com (13%).

Challenges of Verifying Emails at usrab.com

Verifying email addresses at usrab.com can be challenging due to several reasons:

• Catchall Emails: As mentioned earlier, usrab.com has a catchall email setup, which means that traditional email verification services may not be able to accurately verify email addresses.
• Email Security Gateways: There is no information available on whether usrab.com uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it can make simple SMTP tests fail, making it even harder to verify email addresses.
• No Bounce Messages: usrab.com may not always return a bounce message even if you send a test message to an invalid email address, which can make it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at usrab.com

Not verifying email addresses at usrab.com can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list will be outdated, and you may see a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate.
• Risky Emails: Other services may leave most emails at usrab.com as risky, leaving you unsure of how to deal with them. If you keep the emails, you may risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
• Account Restrictions: If your bounce rate is too high, your email service providers may restrict your account.
