Verifying emails from yesster.com can be a challenging task, especially when it comes to catchall emails. In this blog post, we'll discuss the challenges of verifying emails from yesster.com, the risks of not verifying them, and how to use BounceBan to verify these emails accurately.

Understanding yesster.com

Before we dive into the challenges of verifying emails from yesster.com, let's take a brief look at the company. YESSTER GmbH is an online media company based in Aulendorf, Baden-Württemberg, Germany. The company's domain is yesster.com, and it uses a catchall email system, which means that it accepts all emails sent to its domain, regardless of whether the email address exists or not.

The most common email pattern at yesster.com is js@yesster.com (18%), followed by johns@yesster.com (14%), j.smith@yesster.com (11%), and john.s@yesster.com (9%). The company's MX records are smtpin.rzone.de.

Challenges of Verifying Emails from yesster.com

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

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

Risks of Not Verifying Emails from yesster.com

Not verifying emails from yesster.com can lead to several risks:

• 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, 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 yesster.com as risky, making it difficult to decide what to do with them. If you keep them, you risk seeing a high bounce rate; if you delete them, you risk missing potentially valuable valid emails.
