Graded opens on your real list in Outlook and Gmail, plus AI follow-up drafts in the web app. LinkedIn follow-up is a paid add-on.
Apple Mail Privacy Protection
Apple Mail is where most tracked email gets opened, and Mail Privacy Protection loads remote images for everyone who switches it on, whether or not they read.
Bot opens and clicks
Measured, not estimated: Omnivery classified billions of opens and clicks from 2020 to mid-2026 and reported each kind of recipient separately. Omnivery sells bot detection, so read these as a vendor's study.
Bulk-sender rules (Google / Yahoo / Microsoft)
The 2024 bulk-sender authentication rules reshaped deliverability requirements for senders above 5,000/day to consumer addresses.
Response speed and buying groups
Published research on how fast companies answer leads and how many people a B2B purchase involves. Both response studies measured inbound web leads, not email threads.
Outsolvi open grading
How Outsolvi grades opens. These are settings read from the product and the way accuracy gets checked, not an accuracy rate. The product doesn't compute a single one, so we don't quote one.

Frequently asked
Where do these email tracking statistics come from?
Each number names its source and links to it: Apple, Google, the IETF, Litmus, Microsoft, Omnivery, Gartner, Harvard Business Review and the 2007 Lead Response Management study. The Outsolvi entries are settings read from the product. We don't publish statistics about customers' email. The full source index is at /research-sources.
How often is this page updated?
When a source publishes new figures or a rule changes. Apple Mail's share of opens, for example, comes from Litmus's monthly market share page, so it's the number most likely to move.
Why are open rates inflated in 2026?
Because machines load tracking pixels too. Apple Mail Privacy Protection loads images for everyone who turns it on, and Apple Mail accounted for 62% of the opens Litmus measured in July 2026. In consumer email, Omnivery found roughly half of all opens were non-human every year since 2023. Corporate security gateways add their own opens and clicks: at large companies, 80-95% of clicks were bots. How inflated your own open rate is depends on who you email.
What B2B reply rate should I target?
Your own history is the most useful target. Published cold-email benchmarks vary a lot by vendor, list and how replies are counted, so compare each campaign against your previous ones, and expect warm introductions to reply far more often than cold lists.
What's the practical impact of the 2024 bulk-sender rules?
Senders above 5,000 messages/day to consumer addresses must implement SPF + DKIM + DMARC (p=none at minimum), one-click unsubscribe via List-Unsubscribe-Post header, and keep the spam complaint rate below 0.1%, never reaching 0.3%. Microsoft consumer-mailbox enforcement followed from 5 May 2025.

Outsolvi grades every email open from what the request looks like: where it came from, which app made it, and how soon after sending it arrived. 14-day free trial, no credit card.
Start free trialNate 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.
