Verifying email addresses from specific domains can be a daunting task, especially when it comes to domains like uls.edu.sv, which is a catchall domain. In this blog post, we'll explore the challenges of verifying emails from uls.edu.sv, the risks of not verifying them, and how BounceBan can help you accurately verify these emails.

About Universidad Luterana Salvadoreña (ULS)

Universidad Luterana Salvadoreña (ULS) is an e-learning institution based in El Salvador. The university's domain, uls.edu.sv, is a catchall domain, which means that it can be challenging to verify email addresses from this domain.

Challenges of Verifying Emails from uls.edu.sv

Verifying email addresses from uls.edu.sv can be difficult due to several reasons:

• Email Security Gateways (ESG): It's unclear whether uls.edu.sv uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it would make it challenging for traditional verification services to verify emails.
• Catchall Domain: uls.edu.sv is a catchall domain, which means that simple SMTP tests used by traditional verification services may not work.
• No Bounce Message: Even if you send a test message to an invalid email address at uls.edu.sv, it may not always return a bounce message, making it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails from uls.edu.sv

Not verifying email addresses from uls.edu.sv can lead to several risks, including:

• High Bounce Rate: If you don't verify emails, your list may contain invalid or non-existent email addresses, leading to a high bounce rate. This can damage your sending reputation and result in a lower delivery rate, open rate, and click rate.
• Outdated List: An unverified email list can become outdated quickly, leading to a high bounce rate and potential restrictions from your email service providers.
• Risky Emails: Other services may leave most emails at uls.edu.sv as risky, making it difficult to know 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.

Why BounceBan?

BounceBan is the only service that can accurately verify catchall emails and emails behind Email Security Gateways. Services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter are unable to verify catchall emails.

Approximately 40-50% (increasing over time) of business emails are catchalls, which are not verifiable by other services. BounceBan, however, can accurately verify over 80% of these emails with a 97%+ accuracy rate. Catchall emails that cannot be verified with certainty will be tagged as 'risky', accounting for about 20% or less.

BounceBan's success rate in verifying catchall emails is on a consistent upward trajectory. It verifies millions of emails daily and leverages advanced AI to recognize patterns and enhance accuracy. BounceBan verification is fast, taking only a few seconds for most emails, and a few minutes for a small share of catchall emails. You can verify thousands of emails concurrently.

Unlike services like Scrubby, BounceBan never has to actually send an email to verify the email, making it completely compliant with GDPR. Scrubby, on the other hand, verifies emails by sending emails, which can be risky and limiting.
