As businesses expand their online presence, email verification becomes a crucial step in maintaining a healthy and effective email list. One such domain that presents unique challenges in email verification is ub4.eu. In this blog post, we'll delve into the basics of ub4.eu, the difficulties of verifying emails from this domain, the risks of not verifying, and how BounceBan can help you overcome these challenges.

Understanding ub4.eu

ub4.eu is a domain that operates in an unspecified industry. With its domain set to catchall, it means that the domain accepts all emails sent to it, regardless of whether the email address exists or not. This setup can make email verification a daunting task.

The most common email pattern used at ub4.eu is jsmith@ub4.eu, accounting for 21% of all email addresses. Other popular patterns include johnsmith@ub4.eu (15%), john@ub4.eu (12%), and john.smith@ub4.eu (7%).

Challenges of Verifying Emails at ub4.eu

Verifying emails at ub4.eu can be a complex task due to several reasons:

• Email Security Gateways (ESG): There is no information yet about whether ub4.eu uses ESGs, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it would make simple SMTP tests fail, adding an extra layer of complexity to email verification.
• Catchall Setup: As mentioned earlier, ub4.eu is set to catchall, which means that traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails accurately. These services rely on simple SMTP tests, which can be ineffective against catchall domains.
• No Bounce Messages: Even if you send test messages to invalid email addresses at ub4.eu, the domain may not always return a bounce message. This makes services like Scrubby, which rely on bounce messages to verify emails, ineffective.

Risks of Not Verifying Emails at ub4.eu

Not verifying emails at ub4.eu can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, you may end up with a high bounce rate, damaging your sending reputation and resulting in lower delivery rates, open rates, and click rates.
• Outdated Lists: Failing to verify emails can lead to outdated lists, which can further exacerbate the problem of high bounce rates.
• Account Restrictions: If your bounce rate is too high, your email service providers may restrict your account, limiting your ability to send emails.
