Mail security, spam and deliverability
How Kazi Mail verifies senders with SPF, DKIM and DMARC, blocks tracking pixels and spam, and makes sure your email reaches Gmail and Outlook inboxes.
Verified senders
When a message arrives at your @kazios.app mailbox, Kazi's mail server checks who really sent it using three standards:
- SPF: was it sent from a server allowed to send for that domain?
- DKIM: is the message signed by the sender's domain, and unchanged?
- DMARC: do the checks match the address shown in "From"?
Kazi Mail shows the result above the conversation:
| Badge | Meaning |
|---|---|
| Verified sender | The checks passed: the email really comes from that domain |
| Sender not verified | The checks failed. Be careful with links, attachments and payment requests |
| No badge | No verdict is available (for example your own sent mail) |
Hover over a badge to see the individual SPF, DKIM and DMARC results.
Warning: A verified sender can still be a scammer who owns their own domain. Always double-check unexpected payment requests by phone.
Tracking pixels
Many marketing emails contain invisible 1×1 images that tell the sender when and where you opened them. Kazi Mail removes these before showing the message.
Spam and viruses
Kazi's mail server scores every incoming message for spam (unwanted mail goes to Spam) and scans attachments for viruses.
Your email reaches the inbox
Mail you send from @kazios.app is:
- sent over encrypted connections (TLS) whenever the receiving server supports it;
- signed with the kazios.app DKIM key;
- covered by kazios.app's SPF and DMARC records.
This is why Gmail, Outlook and others can verify your mail and deliver it to the inbox.
Report abuse
Forward phishing or abuse coming from a @kazios.app address to abuse@kazios.app.
