Authenticated identity
Checks whether the sending domain and message can prove who they came from.
A personal communication boundary for your domain
Decide what reaches you before it becomes inbox work.
TrustSender receives email for your custom domain. TrustSender Mail Services interprets authenticated sender identity, relationship history, message purpose, and the intent you describe in ordinary language.
Working public prototype with live SMTP decisions and a customer Activity view.

HoldWhy TrustSender paused delivery
The domain identity is valid, but the Agent is uncertain whether this new proposal belongs. It is held outside the inbox for your review.

Email admission controlled by you—not just a spam score.
Permission, not probability
A safe message can still be unwanted.
Traditional filters identify abuse. TrustSender adds the question only you can answer: does this communication belong in your space?
A traditional filter asks
- Does this resemble abuse?
- Is the sender technically authenticated?
- Inbox, junk, or quarantine?
TrustSender also asks
- Do you want this communication?
- Is the sender known, expected, or blocked?
- Should it enter your communication space at all?
Policies in your language
Your policy should sound like you.
Describe the Agent's intent without learning mail-server rules. It can interpret people, organizations, relationships, subjects, meaning, receiving addresses, and the uncertainty that should result in Hold.
These examples show the intended TrustSender experience as the policy model continues to develop.
“Always allow mail from my children and put it first.”
“Reject sales outreach about website redesigns.”
“Allow my dentist’s office, even when a new staff member writes.”
“Hold uncertain messages for me to review instead of making a permanent decision.”
Decisions built from evidence
Trust is more than a From address.
TrustSender translates transport evidence, history, and policy into reasons a person can understand and correct.
Relationship history
Uses prior communication and your corrections to understand who is expected.
TrustSender Mail Services
Interprets the intent, authority, and uncertainty behavior you approved for the receiving address.
Recent decisions
Avoids repeatedly spending your attention on the same message.
Act during delivery
Make the decision while delivery is still in progress.
Because TrustSender can operate as the mail service for a custom domain, TrustSender Mail Services can Allow a message, Hold it outside the inbox for review, or Reject it at the boundary when explicit authority permits.

Visible and correctable
Automation you can hold accountable.
TrustSender Activity shows how the Agent read the evidence, which definition/version authorized it, and why the message was allowed, held, or rejected.
01
See the interpretation. Understand each Allow, Hold, or Reject decision in plain language.
02
Correct the record. Release or reject held mail, revise a relationship, or change the Agent definition.
03
Keep authority. Your explicit correction takes priority over later inference.
Trust and safety
Your policy governs the agent. The email does not.
Incoming email is untrusted evidence. A message cannot rewrite your mail-service policy, authorize a tool, expose another person’s mail, or grant itself a trusted relationship.

Questions
Before you change a mail record.
Is TrustSender another spam filter?
No. It uses mail-security evidence, but its purpose is broader: applying your relationship and communication policies to decide what may enter your communication space.
Do I need to change my email address?
The initial service is for custom domains. Your domain’s mail-delivery records point to TrustSender while you keep your existing address.
What happens when TrustSender is uncertain?
TrustSender Mail Services returns Allow, Hold, or Reject. Review is an action on a held message in Activity, and uncertainty without permanent-rejection authority resolves to Hold.
Does the agent have authority to send email for me?
Not by default. Outbound actions require explicit authority, defined scope, frequency limits, an audit record, and loop prevention.
