I run cold for an agency. We've used Hunter, NeverBounce, and ZeroBounce. This matches them on accuracy and is meaningfully cheaper at our volume. Switched everything over in March. Priya Nair

Common Questions About green.ch
Is green.ch a disposable or temporary email provider?
No. green.ch is not a disposable email provider. It is classified as ISP Email Provider operated by green.ch and addresses on green.ch are persistent rather than throwaway. Mail sent to a valid green.ch mailbox reaches a real recipient.
How do I verify if a green.ch email address is valid?
The fastest way to verify a green.ch email address is to use our free email checker. Enter any @green.ch mailbox at the top of this page and our system performs a real-time SMTP handshake against green.ch's mail servers, confirming whether the mailbox exists, is reachable, and is safe to send to. No email is ever delivered during the check.
Can I check if a green.ch email exists without sending a message?
Yes. Our real-time email verification API connects directly to green.ch's mail server, opens an SMTP session, and queries the mailbox using the RCPT TO command without ever transmitting an actual email. The server's response confirms whether the green.ch mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for green.ch?
green.ch currently publishes 1 mail exchange (MX) record. The primary MX is green-ch.mail.protection.outlook.com, which is the first server contacted when other mail systems try to deliver email to a green.ch address. The full list with priorities and IP addresses is in the MX Records panel above. MX records tell sending servers where to route email for green.ch.
Does green.ch use SPF, DKIM, and DMARC email authentication?
green.ch enforces all three email authentication standards: SPF, DKIM, and DMARC (policy: reject). This is the gold-standard configuration. It means receivers can verify that mail claiming to come from @green.ch is genuine, and green.ch's DMARC policy of 'reject' instructs receivers how to handle messages that fail those checks.
Why do emails to green.ch bounce or get blocked?
Bounces from green.ch usually fall into three buckets: the mailbox doesn't exist (5xx user unknown), the inbox is full, or your sending domain isn't authenticated to green.ch's satisfaction. The fastest fix is to run each address through a free email verifier before you send, and to make sure your own SPF, DKIM, and DMARC are configured correctly so green.ch's receivers trust you.
How can I verify a large list of green.ch email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of green.ch addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, green.ch catch-all detection, role-account detection, and disposable-domain matching. Results typically come back within minutes and previously-failed addresses on your blacklist are reprocessed for free. For continuous high-volume needs, see our unlimited email verification API.
Is it safe to accept signups from green.ch email addresses?
Yes, with normal hygiene. green.ch is a legitimate email service and signups from @green.ch behave like any other real user. Pipe each address through a real-time email verifier API at the moment of signup to catch typos and dead mailboxes, but there is no need to block green.ch by default.
What email format does green.ch use for usernames?
Most green.ch mailboxes follow common patterns like first.last@green.ch, firstinitiallast@green.ch, or first@green.ch, but the actual local-part rules depend on green.ch. The only reliable way to confirm whether a specific @green.ch address exists is to run it through a free email verification tool. Guessing patterns will produce a high bounce rate and damage your sender reputation.
How is the green.ch risk score calculated?
The 0-to-100 risk score for green.ch combines disposable-domain classification, mail-server reachability, MX record presence and depth, SPF / DKIM / DMARC enforcement, DMARC policy strength, SMTP banner response, and domain age. Lower scores mean safer to send to. Disposable domains are pinned at the high end of the scale. The green.ch score is recomputed on every audit so it always reflects the live state of the domain.
Is green.ch a valid email domain?
Yes, green.ch is a valid email domain operated by Green.ch, a Swiss internet service provider offering broadband and email services to Swiss customers.
