Pricing
Free during early access.
Every feature is switched on, nothing is capped, and there is no card to enter. MailSignals will have a price before general availability, and the people using it now will hear what it is before anyone else.

What you get, at no cost, today
This is the whole product. There is no feature held back for a tier that does not exist yet.
- Open tracking with checkmarks in Gmail, and a reason behind every verdict.
- Link click tracking with signed redirects, including URLs you typed as plain text.
- Reply and bounce detection, read from the Gmail page rather than your mailbox.
- Self-open suppression, so your own reads of your Sent folder are not counted.
- Alerts: first open, clicks, replies, bounces, hot threads, revived threads and follow-up reminders.
- The full dashboard: open and reply rates, a best-time-to-send heatmap, per-contact engagement.
- A daily or weekly summary email, at an hour you choose in your timezone.
- Unlimited history. Nothing expires after seven days and nothing is trimmed to the first open.
- Tracking for mail your AI agent sends through the Gmail API, with an MCP server.
- Export as CSV or JSON, and delete everything, whenever you want.
What the alternatives charge, and what they gate
Commercial Gmail trackers run $3 to $6 per user per month, which is $36 to $72 a year, and most of what people pay for is history, branding removal, link tracking and reminders. All of that is included here.
| Feature | Commercial Gmail trackers | MailSignals |
|---|---|---|
| Full tracking history | Paid; free tiers keep 7 days, or only the first open | Included, kept as long as you want it |
| No "Sent with…" signature on your mail | Paid | There is no branding. A disclosure footer is optional and yours to write |
| Link click tracking | Paid, often capped at ten messages | Included, uncapped |
| Follow-up reminders, hot and revived threads | Paid | Included, thresholds adjustable |
| Daily or weekly report email | Paid for anything beyond daily | Included, your hour, your timezone |
| Per-contact engagement, best-time heatmap | Paid, where offered at all | Included |
| Tracking for mail an AI agent sends | Not offered | Included |
| Mailbox access required to use it | Full Gmail scope: read, compose, send, permanently delete | None, on any plan, ever |
| Per-recipient tracking of group emails | Paid, done by re-creating one message per recipient through the Gmail API | Not offered — it needs the mailbox access we refuse |
| Mobile app, Outlook add-in, campaigns | Paid | Not offered |
Prices are the published per-user monthly plans of the two best-known Gmail trackers at the time of writing, and the gating reflects their own published feature tables. The full comparison covers what MailSignals gives up as well.
Questions about cost
What does "free during early access" actually mean?
Every feature is on, nothing is capped, and no card is asked for. It is not a trial with a timer: it lasts as long as early access does. What it is not is a promise that MailSignals is free forever — it is a product, and it will have a price.
What happens to my data and my account when pricing starts?
Your history stays yours. You will be told the price directly and in advance, with time to decide, and nothing will be switched off underneath you or moved behind a paywall you discover by hitting it. If you decide not to continue, you can export everything as CSV or JSON and delete the rest.
Why not just publish the price now?
Because we would be guessing, and a price picked before we know how people use it is a price we would have to change. Early access is partly for us to learn that. Saying "we have not decided" is more honest than a number we would quietly revise.
Is there a free tier planned?
Not decided, and we would rather say so than imply one. What is decided is that early-access users hear the answer before anyone else.
Can I get an invoice, or pay for a team?
Nothing is billed today, so there is nothing to invoice. Several people can already use MailSignals from one account each, each linking their own Gmail addresses and seeing only their own data. Team billing arrives with pricing.
