Cachet Inbox tells you who has gone cold and what you promised them, right in the thread you are reading. It reads whether a message actually landed from replies and meetings, not a fake open count, and keeps the warmth layer and the pipeline in one place.
Apple Mail preloads every tracking pixel before a human sees it, and Gmail proxies and caches the rest. By 2026, most recorded "opens" are structurally unreliable, and the EU now requires consent before a behavioral pixel fires. Cachet Inbox leads with the signals those changes cannot degrade.
We tell you the truth about what we cannot see. Pixel opens are disclosed, off by default, and always labeled with their reliability, so you never act on a number that is mostly machines.
Relationship tools tell you a contact went quiet. Pipeline tools track the deal. No one puts both on the same thread. Cachet Inbox does: the last time you spoke, whether they are cooling, and the next step you committed to, all attached to the box you are already reading.
Every contact carries a last-touch date and a warmth read from the mail already flowing. The ones slipping away surface first, so a warm lead never quietly dies.
A stage and the deal history sit on the Gmail thread itself. No dashboard tab to open, no context lost switching apps.
A lightweight next-step field on each contact: what you promised, by when. The one thing a pipeline stage never captures.
A business card ecosystem captures the contact and stops. A scheduler books the meeting and stops. Cachet is the whole path as one product, so the person you scan becomes a contact, a booking, and a followed-up relationship without re-typing anything.
The first-touch. A card scan or tap becomes a real contact.
Who they are and how you know them, kept current.
The meeting, without the back-and-forth.
The relationship, warm and answered.You are here
The parts a solo advisor, recruiter, or founder actually uses, in one panel, opt-in everywhere.
Replies and calendar behavior as the primary read, with filtered, disclosed opens as a labeled secondary hint.
Your day sorted by who is most engaged right now, so the next move is obvious, not buried in time order.
Set a follow-up on a thread. The moment they reply, it clears on its own. Nothing to dismiss, nothing to remember.
Personalized batches with a delivery calendar that respects Gmail's limits. Every step stops the instant somebody replies.
Deal count, reply rate, and cooling threads up top, a stage funnel underneath. The view most people need, nothing to configure.
Toggle every surface. Suppress your own opens. No floating bubbles, no pop-ups, no nagging.
The category splits into pipeline tools with no warmth layer and warmth tools with no pipeline. Cachet Inbox holds both, inside Gmail, at a solo-professional price. Here is the honest picture, including where the others still win.

We would rather show you the real line than a roadmap dressed as a product. This is where the build actually stands.
The best-known relationship tool in this category silently merges contacts and loses data, with no way to turn it off. Cachet Inbox never merges without asking, keeps a full undo, and logs an audit trail of every change. Your data hygiene is a promise, not a setting we hope you never find.
Anchored to what an executive already pays for a beautiful inbox, not to a $10 personal CRM. Start free, upgrade when the relationship layer becomes how you work. Prices shown billed annually.

Opens are approximate by nature: Apple Mail preloads pixels, image proxies cache them, corporate scanners fire them. So Cachet Inbox leads with the signals those cannot fake, whether the recipient replied and whether they booked time with you, and treats the classified, filtered open as a labeled secondary hint. You get the truth, not a fake green checkmark.
Streak has the pipeline but no warmth layer; Cloze has the warmth layer but no pipeline, and silently merges your contacts. Cachet Inbox holds both, never auto-merges, and prices for one professional rather than a sales team.
No. The panel runs in your browser and shows data for the thread you have open. Sends go through Gmail's own API, signed in as you. Your mailbox is never synced or stored.
The server-side send rail already is. We are adding a sanctioned Google Workspace add-on for the in-thread sidebar rather than leaning on the fragile DOM-injection approach the most-installed competitor still uses. We name honestly where each piece stands.
That is the plan, at the entry tier and ungated: an MCP server and a public llms.txt so an agent can see who is cooling and what you committed to. No personal-CRM peer ships one; we are building it as a category first.
