About Zierzo.es
Zierzo.es is the domain of ZIERZO TELECOM SL, a telecommunications company based in Madrid, Spain. The company operates in the telecommunications industry and has a significant online presence. With a domain that is prone to catchall emails, verifying emails from zierzo.es can be a challenge.
Challenges of Verifying Emails from Zierzo.es
Verifying emails from zierzo.es can be challenging due to several reasons:
- Catchall Emails: Zierzo.es is set to catchall, which means that simple SMTP tests used by traditional verification services may not be effective in verifying emails from this domain.
- Email Security Gateways: There is no information yet about whether zierzo.es uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it will make it even more challenging to verify emails from this domain.
- Lack of Bounce Messages: Zierzo.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 Zierzo.es
Not verifying emails from zierzo.es can lead to several risks, including:
- High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates.
- Risky Emails: Other services may leave most emails at zierzo.es as risky, leaving you uncertain about how to deal with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
