We built Outsolvi because every email tracker we used was lying to us.
Outsolvi grades every open across Outlook and Gmail for account executives who need the engagement signal to be actionable, not theatrical. The dashboard doesn't say 47 opens when only 3 of them were the buyer. It says 3 real opens and labels the rest as the machines they were.
Why we built it
The founding observation is small but consequential. In late 2021, Apple Mail Privacy Protection started pre-fetching the tracking pixel on email delivered to iPhone and Mac users who turn it on. Security scanners at big companies were already opening links and images before people did. Before long, a big share of reported email opens were machines, not people reading. Most trackers kept counting them as opens anyway.
The teams we were on at the time would see 70-80% open rates on cold campaigns and 2% reply rates. Everyone knew the numbers didn't reconcile, but no tool would tell us which opens to trust. So reps treated all opens as suspect and stopped acting on the signal. The whole investment in email tracking quietly stopped paying back.
Outsolvi is the version of email tracking that survives 2026 mailbox-provider behavior. Every open is graded as a person or a machine, with the reason shown. An email gets a hot-lead flag once it has five or more real opens and two or more clicks. Replies are labeled positive, negative, neutral or out of office. It installs natively in Outlook and Gmail, with one dashboard for both. From $7/user/month billed yearly.

The team
Nate writes most of the editorial content on this site and runs the open-grading methodology behind the product. His background is in B2B sales. he's the AE-buyer persona we built Outsolvi for. The product was built because he kept watching his own dashboard lie to him about what his prospects were doing.
How we approach the content on this site
Every piece of writing on outsolvi.com. the blog, the tools, the comparison pages, the glossary. is written by someone who builds the product and uses it daily. We are not a content farm. We do not generate filler. When a page goes up, it is because we genuinely think the reader needs the specific information in the specific shape we built.
We publish comparison pages that name competitors directly because pretending they don't exist makes the page useless. We try to be fair to the tools we compare against. when Yesware or Mailtrack does something better than we do, we say so. The reader can tell when a page is honest. So can Google.
When mailbox-provider rules change (Apple MPP, Gmail bulk-sender requirements, Microsoft 365 link-scanning behavior), we rewrite the pages they affect. The date a page shows is the date its content last changed, not an auto-touched timestamp.
Our methodology page explains how we grade opens, how we check the grading and where the numbers on this site come from, so you can verify our work.
