<b>Open tracking is quietly killing your deliverability</b>
Every tool defaults open-tracking on. That pixel and the link-wrapping domain are both spam signals.
The mechanics
— Open tracking injects a 1px image from a tracking domain — filters flag external tracking on cold mail
— Click tracking rewrites your links through a redirect domain, often a shared one with bad reputation
— Shared tracking domains mean you inherit other senders' spam history
What the tools let you do
— Smartlead, Instantly, Lemlist: all support custom tracking domains and let you disable open tracking per campaign
— Most users never turn it off because the dashboard looks emptier without opens
The trade: turn off open tracking, lose the (already MPP-broken) open metric, gain measurable placement. Keep click tracking only on a dedicated, warmed custom domain.
Verdict: 5/5 move — disable open tracking on cold campaigns. The metric is fake; the deliverability hit is real.
Who it's for: every cold sender optimizing for inbox placement over vanity dashboards.
