Built to be trusted with your mailbox.

Outbound touches your domain, your mailbox and other people's inboxes. We treat all three with care, and we say plainly where the limits are.

Isolation

Every workspace is sealed off

Each organization's mailboxes, leads, campaigns, replies and drafts are scoped to that organization on the server. Your workspace is decided by your membership, never by anything the browser sends.

Encryption

Mailbox passwords stay locked

Mailbox credentials are encrypted before they are stored and are never returned to the browser, not even to the owner. Repairing a mailbox asks for the new password only.

AI privacy

Prospect data stays out of AI

Drafting uses your brief, business context and a summary of which fields exist. Names, addresses, lead rows, notes and suppression lists are never sent to the writing assistant.

Integrity

Approved means frozen

Each recipient's email is prepared and stored before approval. Nothing is rewritten during sending, and every message traces back to the exact copy and design you approved.

Safe content

Templates can't run code

Email content is structured, and personalization is limited to approved fields. Scripts, unsafe links, hidden handlers and unsafe styles are rejected before saving and again before sending.

Access

Roles that mean something

Owners, managers and members have different powers, checked on the server. Owner-only actions such as ownership transfer and safety policy are recorded in an audit history.

Good for the people you write to.

  • One-click unsubscribe

    Campaigns can include an unsubscribe link and the one-click header. Opt-outs apply across your workspace.

  • Suppression checked twice

    Unsubscribed, bounced and replied contacts are excluded when messages are prepared and checked again just before sending.

  • Stop on reply

    When someone answers, their remaining follow-ups are cancelled automatically.

  • Bounce protection

    A mailbox pauses itself when hard bounces cross the threshold you set, and the owner is told.

What the Cadensiq team can see

Cadensiq administrators manage plans and look at aggregate usage. They are not members of your workspace and do not browse your campaigns, leads or replies by default. If support needs to look at something with you, it happens through a time-limited, recorded support session.
