About Wesser.es

Wesser and Partner is a fundraising company based in Madrid, Spain. Their domain, wesser.es, is a catchall domain, which means that it can be challenging to verify email addresses from this domain using traditional email verification services.

Challenges of Verifying Emails from Wesser.es

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

• Email Security Gateways: Wesser.es may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. These gateways can make simple SMTP tests fail, making it difficult to verify emails.
• Catchall Domain: Wesser.es is a catchall domain, which means that it can be challenging to verify email addresses using traditional verification services. Simple SMTP tests may not work, and services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails from this domain.
• No Bounce Messages: Wesser.es may not always return a bounce message even if you send test messages to an invalid email address at that domain. This makes it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails from Wesser.es

Not verifying emails from wesser.es can lead to several risks:

• High Bounce Rates: If you don't verify emails, you may end up sending emails to invalid addresses, leading to high bounce rates. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at wesser.es 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• Outdated Lists: If you don't verify emails, your list will be outdated, leading to a high bounce rate, damaging your sending reputation, and resulting in lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
