Catch-all detection alone has paid for the subscription. We were hemorrhaging credits at our previous verifier on catch-all domains that accepted the call but never bounced. Saved roughly $400 per month overnight. Brett Anderson · RevOps Manager

htc.net Email Authentication SPF · DKIM · DMARC
SPF
Sender Policy Framework. A DNS record listing which servers are allowed to send mail for this domain. Receivers reject or flag mail from unauthorized servers.
Pass
TXTv=spf1 a ip4:216.114.114.145/32 ip4:216.114.114.146/32 ip4:216.114.114.147/32 ip4:216.114.114.148/32 ip4:216.114.114.99/32 include:mailgun.org include:mobitv.com include:_spf.createsend.com ~all
Authorized senders are defined and pass SPF policy.
DKIM
DomainKeys Identified Mail. The sending server cryptographically signs outbound mail with a private key, and receivers verify the signature using a public key in DNS.
Pass
SELECTORDetected via standard selectors
A DKIM signature was detected. Outbound mail from this domain can be cryptographically verified.
DMARC
Domain-based Message Authentication, Reporting & Conformance. Tells receivers what to do when SPF or DKIM checks fail: none, quarantine, or reject.
Quarantine
TXTv=DMARC1; p=quarantine; rua=mailto:dmarc-report@htc.net; ruf=mailto:dmarc-forensic@htc.net; fo=1
Receivers are instructed to quarantine (route to spam) any mail that fails SPF or DKIM.

Common Questions About htc.net
Is htc.net a disposable or temporary email provider?
No. htc.net is not a disposable email provider. It is classified as ISP Email Provider operated by HTC Communications and addresses on htc.net are persistent rather than throwaway. Mail sent to a valid htc.net mailbox reaches a real recipient.
How do I verify if a htc.net email address is valid?
The fastest way to verify a htc.net email address is to use our email checker. Enter any @htc.net mailbox at the top of this page and our system performs a real-time SMTP handshake against htc.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 htc.net email exists without sending a message?
Yes. Our real-time email verification API connects directly to htc.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 htc.net mailbox is valid, full, or non-existent. The recipient never receives anything and never sees the check.
What are the MX records for htc.net?
htc.net currently publishes 2 mail exchange (MX) records. The primary MX is mail2.htc.net, which is the first server contacted when other mail systems try to deliver email to a htc.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 htc.net.
Does htc.net use SPF, DKIM, and DMARC email authentication?
htc.net enforces all three email authentication standards: SPF, DKIM, and DMARC (policy: quarantine). This is the gold-standard configuration. It means receivers can verify that mail claiming to come from @htc.net is genuine, and htc.net's DMARC policy of 'quarantine' instructs receivers how to handle messages that fail those checks.
Why do emails to htc.net bounce or get blocked?
Bounces from htc.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 htc.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 htc.net's receivers trust you.
How can I verify a large list of htc.net email addresses?
Our bulk email verifier accepts CSV or TXT uploads with thousands or millions of htc.net addresses (or any mix of domains). Every address goes through 30+ checks including SMTP existence, htc.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 htc.net email addresses?
Yes, with normal hygiene. htc.net is a legitimate email service and signups from @htc.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 htc.net by default.
What email format does htc.net use for usernames?
Most htc.net mailboxes follow common patterns like first.last@htc.net, firstinitiallast@htc.net, or first@htc.net, but the actual local-part rules depend on HTC Communications. The only reliable way to confirm whether a specific @htc.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 htc.net risk score calculated?
The 0-to-100 risk score for htc.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 htc.net score is recomputed on every audit so it always reflects the live state of the domain.
Is htc.net a valid email domain?
Yes, htc.net is a valid email domain operated by HTC (Horry Telephone Cooperative), a regional telecom cooperative serving the Horry County and Myrtle Beach area of South Carolina.
Is htc.net a disposable or temporary email service?
No, htc.net is not a disposable or temporary email service. It is a permanent ISP email domain provided by HTC to its broadband subscribers in South Carolina.
What mail servers does htc.net use?
htc.net uses mail servers operated by HTC infrastructure. The MX records direct inbound email to HTC mail gateways for filtering and delivery to subscriber accounts.
Can I send marketing emails to htc.net addresses?
You can send marketing emails to htc.net addresses with valid opt-in consent. Authenticate with SPF and DKIM, comply with CAN-SPAM, and maintain very low complaint rates.
How do I verify an htc.net email address?
You can verify an htc.net email address using an email verification tool that checks MX records and performs SMTP-level validation to confirm the mailbox is active and accepting messages.
