As a business, it's essential to have an accurate and up-to-date email list to ensure effective communication with your customers, partners, and prospects. However, verifying email addresses, especially catchall emails, can be a daunting task. In this blog post, we'll focus on how to verify emails from ustom.fr, a company with a catchall email domain, using BounceBan, the only service capable of reliably verifying catchall emails and emails behind Email Security Gateways.

About ustom.fr

ustom.fr is a company with a catchall email domain, which means that it can receive emails sent to non-existent addresses. This can make it challenging to verify email addresses, as traditional verification services may not be able to detect whether an email is valid or not.

Challenges of Verifying Emails at ustom.fr

Verifying emails at ustom.fr can be tricky due to several reasons:

• There is no information yet about whether ustom.fr uses email security gateways (ESG) to make simple SMTP test fail, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If it uses one, it will be a big challenge.
• ustom.fr may be set to catchall, so that simple SMTP test used by traditional verification services, like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter, millionverifier, can not verify it.
• ustom.fr may not always return a bounce message even if you send test messages to an invalid email address at that domain, making services like Scrubby not work.

Risks of Not Verifying Emails at ustom.fr

Not verifying emails at ustom.fr can lead to several risks:

• Other services may leave most emails at ustom.fr as risky, so that you don't know how to deal with it - if you keep the emails, you may risk seeing a high bounce; if you delete all of them, you risk missing the potentially valuable valid emails.
• If you don't verify emails, your list will be outdated, and result in a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate.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 services providers may restrict your account.
