Yes. You can verify any @Clix.pt address in real time with a direct SMTP handshake that provides 99.7% accuracy. Clix.pt is operated by Sonaecom Portugal, runs 2 mail servers, enforces 1 of 3 authentication standards, and is currently responding to SMTP.
Every check returns one of three clear outcomes so you know exactly what to do with the address.
The mailbox exists and accepts mail. Send with confidence, the address is deliverable.
The mailbox does not exist, is disposable, or will hard-bounce. Remove it to protect your sender reputation.
The server is catch-all or greylisting, so existence cannot be confirmed. Send selectively and watch engagement.
clix.pt publishes 2 MX records. The primary mail exchanger is a.mx.gtt.smail.eu, hosted by smail.eu, and it is currently reachable and answering SMTP. Mail is routed through these servers in priority order, lowest number first.
| Priority | Hostname | IP | Status |
|---|---|---|---|
| 10 | a.mx.gtt.smail.eu | 195.170.168.141 | Reachable |
| 20 | b.mx.gtt.smail.eu | 195.170.168.138 | Reachable |
220-a.mx.portugalmail.pt ESMTP PostfixYes. clix.pt is a valid email provider, operated by Sonaecom Portugal. Addresses are persistent and real mail reaches a genuine recipient. Individual mailboxes still go stale, so verify each one before you send.
A live SMTP handshake connects to Clix.pt's mail server and asks whether the mailbox exists using the RCPT TO command, without ever transmitting a message. The recipient never sees the check.
Each address runs through 30+ checks including SMTP existence, catch-all detection, role-account filtering, and disposable matching. The same engine has verified billions of addresses since 2012.
Every unverified address is a gamble. Here is what happens when you skip verification and mail a list that has not been cleaned.
Free inboxes get abandoned constantly. Verification drops the dead clix.pt mailboxes before you mail them.
Mistyped clix.pt addresses fail a real SMTP check, so they never turn into a hard bounce.
A clean list keeps your bounce rate low, and a low bounce rate is what protects inbox placement on a big send.
Mailing only live clix.pt addresses raises every rate that matters: opens, clicks, and replies.
Clix.pt is Sonaecom Portugal.
clix.pt is a Portuguese email service originally operated by Sonaecom, one of Portugal's major telecommunications and technology companies. The clix.pt domain was part of Sonaecom's consumer internet and broadband brand. Existing email accounts continue to be maintained, serving Portuguese users with standard webmail capabilities.
clix.pt supports SPF authentication for outbound email, with DKIM and DMARC policies configured through the provider's mail infrastructure. As a Portuguese telecom-affiliated email service, clix.pt complies with EU data protection standards (GDPR) and Portuguese communications regulations.
The clix.pt mail servers perform recipient verification and reject messages to nonexistent addresses at the SMTP level. The domain does not operate as a catch-all. Rate limiting may apply to inbound connections from unfamiliar sending IPs, particularly those without established reputation in the Portuguese email ecosystem.
When emailing clix.pt users, authenticate your sending domain with SPF and DKIM records. Portuguese-language content is handled natively, but use proper UTF-8 encoding for accented characters.
