Verifying email addresses is a crucial step in maintaining a healthy email list and ensuring that your messages reach their intended recipients. However, verifying emails from certain domains can be a challenge, especially when it comes to catchall emails. In this blog post, we will discuss the challenges of verifying emails at viruslab.cz and how BounceBan can help you overcome these challenges.

About viruslab.cz

Viruslab.cz is a domain that presents a unique set of challenges when it comes to verifying email addresses. With a catchall setup, it can be difficult to determine whether an email address is valid or not. The domain's email pattern distribution is as follows: johnsmith@viruslab.cz (26%), johns@viruslab.cz (22%), johnsmith@viruslab.cz (11%), and j-smith@viruslab.cz (10%). The most common email pattern is johnsmith@viruslab.cz, which accounts for 26% of all email addresses.

Challenges of Verifying Emails at viruslab.cz

Verifying emails at viruslab.cz can be challenging due to several reasons. Firstly, the domain may use email security gateways (ESG) such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail. This means that traditional verification services may not be able to accurately verify email addresses.

Secondly, the catchall setup at viruslab.cz means that simple SMTP tests used by traditional verification services may not be able to verify email addresses. This is because catchall emails do not return a bounce message even when an email is sent to an invalid address.

Lastly, the lack of information about viruslab.cz's email setup means that it may not always return a bounce message even when an email is sent to an invalid address. This makes it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at viruslab.cz

Not verifying emails at viruslab.cz can lead to several risks. Firstly, other services may leave most emails at viruslab.cz 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. On the other hand, if you delete all of them, you risk missing potentially valuable valid emails.

Secondly, if you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate. If the bounce rate is too high, your email service providers may restrict your account.
