Email tracking features that actually work in 2026
Detailed guides on the structural features that distinguish Outsolvi from generic email-tracking tools in 2026. Each page covers what the feature does, why it matters, how it works mechanically, and how competitors handle (or do not handle) it.
Outsolvi groups them into four categories: tracking accuracy (open grading, the evidence behind each grade, link clicks), AI and signals (Write with AI, reply labels, the hot-lead rule), platform (the Outlook add-ins, the Gmail extension, and what gets stored), and workflow (follow-ups, alerts and team analytics). Each page says what the feature does today, and where it stops.

Graded opens and hot-lead detection native to Outlook and Gmail, plus keyword reply labels in the web app. From $7/mo yearly, no credit card. LinkedIn and outreach are optional add-ons.
Graded opens, the evidence behind each grade, and link-click tracking. They set aside Apple Mail Privacy Protection pre-fetches and security-scanner hits and group repeat Gmail proxy fetches, which is why a raw open rate can sit well above the number of people who read.
Write with AI drafts follow-ups in six tones. Next to it sit the signals that need no AI: the hot-lead rule, reply labels from keyword rules, and the nudge list. Each page says which is which.
The desktop add-in for classic Outlook on Windows, the web add-in for Outlook on the web and new Outlook, and the Gmail extension for Chrome, all feeding one dashboard with the same grading rules. Plus what Outsolvi stores, and what it doesn't.
Follow-ups that thread and stop on replies, pop-up alerts in the Gmail extension and the desktop Outlook add-in, team analytics, and LinkedIn steps as a paid add-on. The features that turn what tracking sees into what a rep does next.
Automated Follow-Up
Automated follow-up is for sellers and founders who keep losing deals because a follow-up slipped. You want the follow-ups to send themselves, without sounding like a mass blast and without sending after someone has already replied.
Multi-Channel Outreach
Multi-channel outreach lets you reach prospects on more than one channel without juggling separate tools, so you're not stuck with email-only sequences that get ignored.
LinkedIn Automation
LinkedIn automation lets you scale your LinkedIn outreach without doing all of it by hand, and without getting your account flagged for the spammy bot behavior LinkedIn watches for.
Graded Opens
Email open confidence scoring is for AEs and sales-ops leads who have noticed that their tracker's open rate doesn't match reality, and who want Apple Mail and scanner noise kept out of the count.
Diagnose
If an email tracker has burned you before, this is for you. You saw an open, called the prospect, and they had never seen the email. You want a tracker whose numbers you can actually verify instead of taking on faith.
Hot Lead Detection
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.
Reply Labels
A rep wants replies sorted so the interested ones get answered first, and wants to know exactly how the sorting works before trusting it.
Unified Dashboard
A unified Outlook Gmail dashboard is for mixed-client teams tired of running two trackers, one for Outlook and one for Gmail, with no single view across both.
Tracking Privacy
Metadata-only email tracking matters most if you're an AE, founder, or RevOps lead selling into regulated industries, where procurement reviews scrutinise what the tracking tool stores.
Open Alerts
Open alerts should reach you fast enough to act on while the prospect is still thinking about you, without the tracker telling you forty times a day about opens that were never people.
Document Links
Document tracking tells you whether a prospect opened the proposal you sent. The question is whether a tool gives you per-page reading analytics or just link clicks.
Team Analytics
A sales manager wants to see how much each rep is sending and how it's landing, without asking reps to log anything.
Write with AI
A rep writing follow-ups all day wants a fast first draft that sounds like a person, not a template, and wants to stay in control of what gets sent.
Repeat Engagement
Engagement velocity helps you spot prospects who are heating up. What matters is whether a tool actually computes trend deltas over time or simply counts engagement.
Follow-Up Help
A rep wants to know which sent emails need a follow-up today, and wants help writing it, without building a cadence first.

Start Free TrialFrequently asked
What's the most important feature in 2026?
Open grading. Apple Mail Privacy Protection and corporate scanners (Microsoft Defender, Mimecast, Proofpoint) create opens nobody made, and Gmail's image proxy can report one read as several fetches. Without open grading, every signal that depends on opens (hot-lead detection, open rates, the nudge list) runs on noisy data.
Are AI features included or gated?
Write with AI, the part that is AI, is in the web app's Schedule follow-up editor, on the $7 Individual plan and the free trial. The hot-lead rule and reply labels are rules rather than AI, and they're on the Individual plan too.
Does Outsolvi work on both Outlook and Gmail?
Yes. The desktop add-in covers classic Outlook for Windows, the web add-in covers Outlook on the web and new Outlook, and the Gmail extension runs in Chrome. They all feed the same dashboard with the same grading rules. Outlook for Mac doesn't track yet.
What's the data-privacy posture?
Tracking needs no email body. For each open and click it records the time, IP and user agent. If you connect a mailbox for follow-ups and reply detection, Outsolvi syncs its mail, including sent mail, and stores it encrypted. Follow-ups you write are stored too. SOC 2 aligned controls (not audited), AES-256 at rest, TLS 1.2 or 1.3 in transit. Data is hosted in the US.

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.
