No DKIM signature was detected. Receivers cannot verify the integrity of outbound mail.
DMARC
Domain-based Message Authentication, Reporting & Conformance. Tells receivers what to do when SPF or DKIM checks fail: none, quarantine, or reject.

Common Questions About gci.net
Is gci.net a disposable or temporary email provider?
No. gci.net is not a disposable email provider. It is classified as ISP Email Provider operated by GCI Alaska and addresses on gci.net are persistent rather than throwaway. Mail sent to a valid gci.net mailbox reaches a real recipient.
How do I verify if a gci.net email address is valid?
The fastest way to verify a gci.net email address is to use our free email checker. Enter any @gci.net mailbox at the top of this page and our system performs a real-time SMTP handshake against gci.net'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 gci.net email exists without sending a message?
Yes. Our real-time email verification API connects directly to gci.net'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 gci.net mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for gci.net?
gci.net currently publishes 1 mail exchange (MX) record. The primary MX is inbound.gci.net, which is the first server contacted when other mail systems try to deliver email to a gci.net 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 gci.net.
Does gci.net use SPF, DKIM, and DMARC email authentication?
gci.net has 2 of the 3 standard email authentication records in place: SPF, and DMARC (policy: none). Adding the missing layer(s) would tighten anti-spoofing protection and improve deliverability for legitimate gci.net mail.
Why do emails to gci.net bounce or get blocked?
Bounces from gci.net 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 gci.net'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 gci.net's receivers trust you.
How can I verify a large list of gci.net email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of gci.net addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, gci.net 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 gci.net email addresses?
Yes, with normal hygiene. gci.net is a legitimate email service and signups from @gci.net 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 gci.net by default.
What email format does gci.net use for usernames?
Most gci.net mailboxes follow common patterns like first.last@gci.net, firstinitiallast@gci.net, or first@gci.net, but the actual local-part rules depend on GCI Alaska. The only reliable way to confirm whether a specific @gci.net 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 gci.net risk score calculated?
The 0-to-100 risk score for gci.net 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 gci.net score is recomputed on every audit so it always reflects the live state of the domain.
Is gci.net a valid ISP email domain?
Yes, gci.net is a valid email domain provided by GCI Alaska to its internet subscribers. It is a legitimate ISP-issued email address.
Is gci.net a disposable or temporary email provider?
No, gci.net is not a disposable or temporary email provider. It is an ISP-provided email service tied to an internet subscription from GCI Alaska.
What mail server does gci.net use?
gci.net uses mail servers operated by GCI Alaska. Check the MX records section above for specific server details and authentication configuration.
Can I send marketing emails to gci.net addresses?
Yes, you can send marketing emails to gci.net addresses with proper opt-in consent. ISP email providers apply spam filtering, and addresses may become inactive if subscribers cancel their internet service. Regular list verification is recommended.
How do I verify an email address at gci.net?
Use BulkEmailChecker to verify gci.net addresses via SMTP checks. ISP domains may have specific rate limiting or greylisting behaviors. Our tool handles these provider-specific configurations automatically.
