Email Tracker Under $10/Month for Outlook

The sub-$10 email tracker market is heavily Gmail-only. Mailtrack at $9.99 is Gmail. Vocus.io at $5 is Gmail. Streak at $19 starts above the price band. For Outlook teams who want a sub-$10 per seat tracker, the options narrow to four. and only one of those delivers AE-grade tracking features.

This ranking is for Outlook AE teams operating on a strict per-seat budget. Four options under $10 per user per month yearly that run on Outlook (Desktop, Web, New Outlook), ranked by feature depth at that price ceiling.

TL;DR

Outsolvi at $7 yearly is the only sub-$10 Outlook tracker with confidence-tier scoring and AI follow-up signals. Right Inbox at $7.95 is a productivity tool with light tracking. Boomerang at $4.99 covers send-later and reminders. Mailbutler Tap at $8.95 is a productivity assistant. For real sales tracking depth under $10 on Outlook, Outsolvi is structurally unique.

How we ranked these tools

Each tool was evaluated against three criteria: native Outlook support including Desktop, Web, and New Outlook (40%), feature depth at the base tier (35%), tracker accuracy in 2026 (25%). Pricing reflects yearly per-seat billing as of May 2026. Tools above $10 per user per month yearly were excluded entirely. Tools that do not run natively on Outlook were also excluded.

Frequently asked questions

Why is Outlook tracker market so much smaller than Gmail?+

Three reasons. (1) Office 365 administrators historically restricted add-ins more aggressively than Google Workspace, raising the cost of adoption. (2) The Outlook add-in development model (Office.js, manifest XML, AppSource review) is heavier than Chrome extensions. (3) Outlook's recipient profile skews enterprise, where buyers favor full sales-engagement platforms over standalone trackers. The result is a thinner under-$10 market on Outlook than Gmail.

Will the under-$10 ceiling hold or are prices rising?+

Outsolvi has publicly committed to maintaining the $7 yearly tier through 2026 at minimum. Mailtrack and Vocus.io have not raised under-$10 pricing since 2023. The under-$10 ceiling is durable for at least the near term.

Can a 5-rep team afford the per-seat math on these tools?+

5 reps × $7 Outsolvi yearly = $420/year ($35/month). 5 × $4.99 Boomerang = $300/year. 5 × $7.95 Right Inbox = $477/year. All four options sit comfortably under $500/year for a 5-rep team, well within standard SaaS budget. The decision is feature depth, not affordability.

What features are missing at the under-$10 tier vs. premium trackers?+

Conversation intelligence (call recording analysis), advanced sequencing motion, large-volume cold-email infrastructure, and CRM-deep integration. None of these are necessary for AE-grade email tracking. Reps who need them typically run a separate tool (Gong for calls, Smartlead for cold) alongside the tracker.

What's the trial workflow like for Outlook under-$10 tools?+

Outsolvi's 14-day trial requires no credit card and ships the full feature set during the trial. Right Inbox offers a 14-day free trial. Boomerang has a perpetual free tier (limited) plus paid tiers. Mailbutler has a 14-day free trial of the Smart tier (which drops to Tap or Essential after).

Is the cheapest option always Mailtrack on free tier?+

On Gmail, yes. Mailtrack's free tier (with the branded signature) is the cheapest workable tracker. On Outlook, Mailtrack is not an option. The cheapest Outlook tracker is Boomerang at $4.99/user/mo Personal tier, but tracking depth at that price is minimal.

How to read this ranking

The under-$10 Outlook tracker market exists because budget-constrained AE teams (early-stage startups, agencies, consultancies, small mid-market) are unwilling to pay $35 to $90 per seat for tracker functionality they perceive as commodity. That perception is mostly correct for the 2014 to 2020 generation of trackers. It is incorrect for the 2024 to 2026 generation, where confidence scoring and AI follow-up materially improve rep workflow.

The structural answer for the budget-constrained Outlook team is to pick a sub-$10 tracker that delivers the modern feature set rather than under-spec at $4.99 productivity tooling. The annual savings of $4.99 versus $7 ($24 per rep per year) is meaningless next to the rep-hours saved by not chasing phantom opens or missing warm-thread replies.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi runs Tier 1 to 5 confidence scoring on every open, native in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
