Best Cheap Email Tracking Under $10/mo in 2026

The under-$10/month price band is where most solo sellers, founders, and 1-3 rep small teams shop for email tracking. The category at this price point splits into Gmail-first specialists (Mailtrack, Vocus, Right Inbox) and cross-platform options (Outsolvi). The cheaper end of the range mostly lacks confidence scoring and AI features; the deciding question is whether the trade-off matches your motion.

This ranking is the six trackers under $10/user/month yearly in 2026, ordered by what you actually get for the money rather than just on price.

TL;DR

Outsolvi Individual at $7/user/mo yearly is the only under-$10 tier that grades every open as a person or a machine and includes hot-lead detection, reply labels and Outlook and Gmail support. The other five (Mailtrack Pro, Vocus.io Basic, Mailbutler Professional, Right Inbox Professional, Boomerang Personal) are all Gmail-first or scheduling-first, and none has confidence scoring or AI features at this price point.

Frequently asked questions

What is the cheapest email tracking tool with real features?+

Outsolvi Individual at $7/user/mo yearly is the cheapest tier in the category that grades every open as a person or a machine, labels replies, flags hot leads, drafts follow-ups with AI, and supports native Outlook + Gmail. Mailtrack Pro at $4.99 yearly is $2 cheaper but tracks only opens in Outlook and has no confidence scoring or AI features. For tracking-first work, Outsolvi is the better value at $7.

Why is Outsolvi cheaper than Yesware or Mixmax?+

Different positioning. Yesware Pro at $15/user/mo yearly and Mixmax Inbox Copilot at $29 are priced as sales-engagement platforms with sequences, scheduling, and CRM features bundled. Outsolvi is priced as a focused tracking-intelligence tool, so the per-seat math is lower. For teams that just need tracking, the bundled features in Yesware and Mixmax are mostly stranded value.

Are cheap email trackers good for B2B sales?+

Depends on what you mean by good. Cheap trackers (Mailtrack Pro, Vocus, Boomerang Personal) work for personal tracking and Gmail-only solo selling where reply rate is the KPI. For B2B AE work where you route follow-ups off open data, you need each open graded as a person or a machine, so Apple MPP and corporate-scanner pre-fetches stay out of the count. Outsolvi at $7 yearly is the cheapest tier that does this.

What about free options?+

Mailtrack Free works for personal Gmail tracking but adds "Sent with Mailtrack" to every outgoing email. HubSpot Sales Free is capped at 5 sends per day. Streak Free covers personal pipelines (Gmail-only). The cleanest free-evaluation path for B2B work is Outsolvi's free trial (14 days or 250 tracked emails, no credit card). The detailed free comparison is in [best free email tracking](/best/free-email-tracking).

Can I get a discount on Outsolvi?+

Yearly billing is the discount. Outsolvi Individual is $7/user/mo on yearly billing ($84/year) versus $12/mo on monthly billing ($144/year), a 42 percent yearly discount. Pro is $20/user/mo yearly or $29 on monthly billing. There's no separate enterprise plan: Pro covers unlimited members.

What if I need Outlook tracking under $10?+

Outsolvi Individual at $7/user/mo yearly is the only option under $10 that runs natively on Outlook (classic, web and new Outlook) plus Gmail. The other under-$10 options on this list are all Gmail-only. For Outlook + Gmail tracking with graded opens under $10, Outsolvi is the only choice.

Ready to try the #1 pick?

Outsolvi's free trial (14 days or 250 tracked emails) requires no credit card. After the trial, $7/user/mo on yearly billing or $12/mo on monthly billing keeps graded opens, hot-lead flags, reply labels, AI-written follow-ups and native Outlook + Gmail going.
