As a professional in the sales, marketing, AI, CRM, or B2B sectors, you understand the importance of maintaining a clean and accurate email list. However, verifying emails from certain domains can be a daunting task, especially when it comes to catchall emails. In this blog post, we'll discuss the challenges of verifying emails from topsystem.be, a company in the information technology and services industry based in Brussels, Belgium.

About topsystem.be

topsystem.be is a company that operates in the information technology and services industry. Their domain, topsystem.be, is set to catchall, which means that they receive all emails sent to their domain, even if the email address does not exist. This can make it challenging to verify email addresses from this domain.

Challenges of Verifying Emails from topsystem.be

Verifying emails from topsystem.be can be challenging due to several reasons:

• Email Security Gateways (ESG): There is a possibility that topsystem.be uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to block simple SMTP tests, making it difficult for traditional verification services to verify emails.
• Catchall Emails: Since topsystem.be is set to catchall, simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails.
• No Bounce Message: topsystem.be may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails from topsystem.be

Not verifying emails from topsystem.be can lead to several risks:

• Risky Emails: Other services may leave most emails at topsystem.be as risky, making it difficult to determine how to handle 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.
• Outdated List: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
