Email Marketing Metrics Calculator

How to use

1. 1Pick a mode: Campaign rates for a single send, Revenue and ROI when you have money attached, Compare campaigns to line up to 8 sends, or Benchmarks to check ranges by industry.
2. 2In Campaign rates, enter Sent, Delivered, Soft and Hard Bounces, Unique Opens, Unique Clicks, Unsubscribes, and Spam Complaints. Leave Delivered blank to derive sent minus bounces the way most ESPs do internally.
3. 3Read the Open rate headline, then scan Delivery, Bounce (split by soft and hard), CTR, CTOR, Unsubscribe, and Spam Complaint rates with a copy button next to each value.
4. 4Switch to Revenue and ROI to add Total revenue, Conversions, and optional Campaign cost. The tool computes revenue per recipient, revenue per click, average order value, CPA, net profit, and ROI in the chosen currency.
5. 5In Compare campaigns, fill a label, Sent, and at least opens or clicks for each row. The table highlights Best and Worst CTOR and totals everything into a blended row you can paste into a recap.
6. 6In Benchmarks, type your open rate, CTR, unsubscribe rate, and bounce rate. Each row shows the industry range and flags Above, Within, or Below for every metric you filled in.
7. 7Click Copy summary to grab a plain-text report ready to paste into a Slack thread, email recap, ticket, or quarterly update.

About this tool

Email Marketing Metrics Calculator turns the numbers a campaign manager reads off a Mailchimp, Klaviyo, HubSpot, Campaign Monitor, or SendGrid report into the headline rates needed for a recap, a stakeholder update, or a benchmark check. Campaign mode takes Sent, Delivered, Soft and Hard Bounces, Unique Opens, Unique Clicks, Unsubscribes, and Spam Complaints, then returns Delivery Rate, Bounce Rate (split by soft and hard), Open Rate (unique opens over delivered), Click-Through Rate (unique clicks over delivered), Click-to-Open Rate (unique clicks over unique opens), Unsubscribe Rate, and Spam Complaint Rate. Every formula is shown next to the value so an analyst can verify the math by hand and explain it to a stakeholder. Revenue and ROI mode layers Total Revenue, Conversions, and optional Campaign Cost on top of the same send and computes Revenue per Recipient, Revenue per Delivered, Revenue per Click, Average Order Value, Conversion Rate of unique clicks, Cost per Acquisition, Net Profit, and Email ROI as a percentage. Currency is display-only across eight ISO currencies via Intl.NumberFormat with no exchange rates fetched. Compare campaigns mode lines up to eight sends side by side, ranks the highest and lowest Click-to-Open Rate with Best and Worst badges, and reports blended Delivery Rate, Open Rate, CTR, and CTOR across all rows in a totals row that lifecycle managers can paste straight into a quarterly update. Benchmarks mode lists typical Open Rate, CTR, Unsubscribe Rate, and Bounce Rate ranges across eleven industries aggregated from widely-cited Mailchimp, Campaign Monitor, HubSpot, and Klaviyo public reports; type your own numbers into four fields and every row flags Above, Within, or Below the typical range for each metric without skipping rows where you only have part of the picture. Inline validation catches counts that exceed sent or delivered before the math runs (the tool refuses, for example, to let you claim more unique clicks than unique opens) and the Delivered field can be left blank to derive Delivered = Sent minus Bounces the way most ESPs do internally. Useful for lifecycle managers writing recaps, retention marketers tuning send cadence, growth teams comparing winback to broadcast, agencies benchmarking client performance, founders sanity-checking newsletter ROI, and anyone who has ever had to explain CTR versus CTOR in a meeting. All math runs in your browser; nothing is uploaded.
