CompetitorInbox gives you the same competitor email intelligence MailCharts used to — subject lines, send cadence, creative tracking — plus DNS Auth Score and ESP detection MailCharts never offered. Self-serve. No sales call. Plans from $15/mo.
In November 2025, MailCharts — acquired by Litmus — discontinued its self-serve $99–299/mo plans and moved to enterprise-only sales. If you were on a self-serve MailCharts plan, you're either already locked out or facing a sales-led renewal at a much higher price. You're not the only one looking for what's next.
We're specific about where we win and plain about where we don't. Panoramata covers ads and SMS and social too — we don't try to compete there. We focus on email, deeper.
