Hot lead detection
A tracker that calls an email hot after a few opens will call a lot of machines hot. Apple Mail and security scanners open email on their own, so a few opens often means nothing. Outsolvi's rule asks for more: five opens graded as a person, and two clicks on your links, on the same email.
When an email crosses that line, it gets a flame in Outsolvi, and the Gmail extension or the desktop Outlook add-in pops up to tell you. The rule is fixed and the same for everyone, so a hot lead means the same thing on every rep's list.
Who this is for
A rep wants to know which sent email a prospect keeps coming back to, without counting Apple Mail pre-fetches and security scans as interest.
The rule, stated
Five real opens and two real clicks. Nothing else moves the number.
The threshold is fixed and public, so you can count it yourself on any tracked email. Machine events are recorded with their reason and never touch either counter.
Counted
Threshold met. Two machine events on this email were set aside and changed neither number.
What it does
Outsolvi marks an email as a hot lead once it has five or more opens graded as a person and two or more link clicks, and tells you with a flame and a pop-up. It checks the totals each time a counted open or click arrives: the flame shows on the email in Outsolvi, and the Gmail extension or the desktop Outlook add-in shows a hot-lead pop-up. Hot emails also appear in the Feed's Hot Prospects panel and in your weekly summary email.
Why it matters in 2026
Five real opens and two clicks is a pattern machines rarely produce, so the flag points at a person paying attention
Apple Mail pre-fetches and security scans don't count toward it, so a burst of machine opens can't trip it
A fixed rule is easy to explain to a team: everyone knows what hot means
The pop-up reaches you in Gmail or Outlook, where you already work, instead of waiting for you to check a dashboard
It all works from your very first send.

How it works
Only counted events move the totals: opens graded verified or most-likely human, and clicks that pass the same kind of checks. Apple Mail pre-fetches, scanner hits, link previews and your own opens are recorded with their reasons but don't count. Each time a counted open or click arrives, Outsolvi checks the email's totals, and at five opens and two clicks it marks the email hot. There's no time window: an email that reaches the totals over three days is as hot as one that reaches them in an hour. The rule counts per tracked email, not per contact, and an email sent to several people in one Gmail message shares one count. The alert goes to the person who sent the email.
Many trackers show open counts and leave the judgement to you. Outsolvi's rule is stricter than a raw open count on purpose: it only counts opens graded as a person, and it needs clicks as well.
Use cases for Hot Lead Detection
Frequently asked questions
What counts as a hot lead in Outsolvi?+
An email with five or more opens graded as a person and two or more link clicks. Both have to happen on the same tracked email.
Is there a time window?+
No. The totals add up over the life of the email, however long that takes.
Can I change the threshold?+
No. It's the same fixed rule for everyone, so a hot lead means the same thing across a team.
How do I find out an email is hot?+
A flame appears on it in Outsolvi. If you use the Gmail extension or the desktop Outlook add-in, you also get a pop-up while it's running and you're signed in. Hot emails show in the Feed's Hot Prospects panel and in your weekly summary email. There are no Slack alerts and no instant emails.
Do Apple Mail opens count?+
Not on their own, because Apple fetches the image whether or not anyone reads. If the same reader clicks or replies, the click or reply is recorded on its own.
Does a reply make an email hot?+
No. Hot lead is about opens and clicks. A reply gets its own label (Positive, Negative, Neutral or Out of office), and it stops any follow-ups scheduled to that person.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi grades every open as a person or a machine, in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
