Introduction

In today's digital age, email verification is a crucial step in maintaining a healthy and effective email list. However, verifying emails from certain domains can be a challenging task, especially when it comes to catchall emails. In this blog post, we will discuss the challenges of verifying emails from viisi.nl, a financial services company based in the Netherlands, and how BounceBan can help you overcome these challenges.

About Viisi.nl

Viisi.nl is a financial services company based in Amsterdam, Netherlands. The company provides mortgage services to its clients and has a strong online presence. With a domain like viisi.nl, it can be challenging to verify emails, especially since it uses a catchall email system.

Challenges of Verifying Emails at Viisi.nl

Verifying emails at viisi.nl can be a daunting task due to several reasons:

• Email Security Gateways: Viisi.nl may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to protect their email system. These gateways can make simple SMTP tests fail, making it difficult to verify emails.
• Catchall Emails: Viisi.nl uses a catchall email system, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work. Catchall emails are emails that are not specifically assigned to a user but are still valid.
• No Bounce Messages: Viisi.nl may not always return a bounce message even if you send a test message to an invalid email address at that domain. This can make it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at Viisi.nl

Not verifying emails at viisi.nl can lead to several risks:

• High Bounce Rate: If you don't verify emails, you may end up with 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 viisi.nl 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; 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• Outdated List: If you don't verify emails, your list will be outdated, leading to a high bounce rate and damaging your sending reputation.
