Read receipts & accuracy.
How opens are detected, and why our numbers are real.
How open tracking worksA tiny invisible image reports the open. It can't read anything — here's the whole mechanism.Bots and scanners are filtered outApple's privacy proxy, corporate scanners, and Gmail prefetches get labeled as machines — never counted as reads.Your own opens don't countChecking your Sent folder won't turn your own ticks green. Here's every protection working for you.Group emails: who exactly opened?A normal group email can't honestly say who opened. Pro individual copies make per-person receipts real.Track clicks on your linksChoose which links to track. Clicks pass through MailViewed's link domain, then straight to your page. A click is the strongest read signal there is.The Hot badge and reply detectionHot marks trustworthy re-engagement: a reply, a real click, or a genuine return visit.Track through your own domainServe the tracking pixel and tracked links from a subdomain you own, such as link.yourcompany.com, so hovering a link shows your name and your reputation is yours alone.
