Email Calculator is a campaign analytics platform that helps marketers measure and optimize email performance.
Enter campaign data manually or connect 55+ platforms. The platform syncs metrics from your email, ROI, and lead sources, then calculates key KPIs in real time — open rate, click rate, CTOR, bounce rate, ROI, and conversion rate — alongside visual analytics and actionable recommendations.
Email Calculator offers a Free plan plus three paid usage tiers:
Free — £0
Starter — £9/month or £90/year
Growth — £29/month or £290/year
Everything in Starter, plus:
Scale — £79/month or £790/year
Everything in Growth, plus 25,000 API requests per month, 500,000 synced records per month, 10 workspaces, 10 team members, and priority support. Enterprise adds custom API limits, SSO, onboarding, and larger historical imports.
Yes. Start with the Free plan (up to 3 reports total) to test the platform with manual data entry, AI features, Campaign Story, Compare, and chart customization.
