Waiting for Them
One focused queue for unreplied emails, ranked by engagement, time waiting, and follow-up urgency.
Privacy-first · Minimal permissions
Know if they read it —honestly.
EmailKnow turns opens, clicks, and replies into a clear Waiting queue, explainable scores, and next-step suggestions. It reads no body by default; AI only processes content you explicitly submit.
No credit card · Headers only by default · AI content is not retained
The honest signal
Four states. No lies.
Most trackers pretend every pixel load is a real read. Apple Mail preloads images, and your own opens get counted too. We label every signal for what it actually is.
- Clicked High intent
They clicked a link. The strongest signal — unaffected by Apple, confirmed human.
- Human open Medium
A genuine open from a non-Apple IP. Likely a real read.
- Apple preload Uncertain
Apple Mail Privacy Protection preloaded the image. We flag it — not a confirmed read.
- Unknown No signal
Never loaded. Maybe unread, maybe images off. We won't guess.
Opens from your own device are detected and excluded — we won't count you reading your own email as a recipient open.
The closed loop
Tracking that drives the follow-up
Competitors stop at tracking and leave you to guess. EmailKnow turns the signal into the decision.
-
Write & send
Compose in Gmail. Optionally attach a follow-up rule.
-
Track signals
Clicks, human opens, Apple preloads, replies — layered by confidence.
-
Decide by signal
Replied → cancel. Read but no reply → a warm nudge. No signal → resend with a new subject.
-
Auto follow-up
Sent in the same thread, at the right time, through your own Gmail.
The signal driving the decision — that's the moat. A generic “no reply → follow up” doesn't know if they even saw it.
Why EmailKnow
From “did they read it?” to “what should I do next?”
Explainable Engagement Score
Never a black-box number. Every point is explained by clicks, human opens, time waiting, and due follow-ups.
Smart follow-up suggestions
Know whether to follow up today, wait, or try a new subject. Suggestions guide you; they never send on their own.
Quiet notifications
No alert for every open. Only meaningful high-priority changes, bundled and throttled for six hours.
On-demand AI drafts
Content is read only after you click and confirm. Drafts are previewed, editable, and inserted only by you.
Honest signals, minimal scopes
Apple MPP is labeled honestly. Default tracking uses only gmail.send and gmail.metadata and never reads message bodies.
Permission posture
Headers by default. AI only when you ask.
Tracking and automation keep minimal permissions. AI drafts are optional, explicit, and processed temporarily.
We do
- gmail.send — send follow-ups on your behalf
- gmail.metadata — read headers (sender, subject, thread) to detect replies
- Sign-in uses openid / email / profile only — no Gmail data
- Only after you click AI follow-up and confirm do we temporarily process selected content
We never
- Default tracking and automation never read message bodies or attachments
- AI inputs and generated drafts are never stored in D1, KV, or persistent logs
- Recipient IP addresses and user-agent strings are not persisted
