Attributed revenue from email sends
What is an email campaign revenue calculator?
An email campaign revenue calculator forecasts how much revenue a campaign cadence, lifecycle flow, or monthly email program may generate from delivered sends, open rate, click-to-open rate, click-to-purchase conversion, and average order value. Ecommerce marketers, CRM teams, lifecycle managers, DTC brands, and retention operators use it to plan campaign revenue, compare RPM, evaluate send frequency, and connect email engagement to orders.
Email campaign revenue formula
The calculator multiplies monthly email volume by open rate, click rate on opened emails, purchase rate from clicks, and AOV. It also calculates revenue per 1,000 emails so teams can compare list monetization across months and campaign types.
Email revenue = Emails sent x Open rate x Click-to-open rate x Purchase rate from click x AOV- Revenue per 1,000 emails = Estimated revenue x 1,000 / Emails sent.
- This wizard expects click rate to be click-to-open rate, not click-through rate on delivered emails.
- For finance reporting, reconcile modeled revenue with ESP attribution, storefront orders, refunds, discounts, and holdout tests.
Inputs explained
Email revenue forecasts are most useful when all engagement and conversion rates use the same audience, send type, and attribution window.
- Total emails sent / month
- The delivered marketing emails, campaigns, flows, or triggered sends included in the monthly forecast. Exclude transactional messages unless their rates are included in the same assumptions.
- Average order value
- The average value of orders attributed to email. Use net AOV after discounts when promotions materially change realized revenue.
- Unique open rate
- The percentage of delivered emails that register a unique open. Apple Mail Privacy Protection can inflate this metric, so compare it with click-based behavior.
- Click rate on opened
- The click-to-open rate, or unique clicks divided by unique opens. Convert delivered-email CTR before entering it here.
- Purchase rate from click
- The percentage of clicked sessions or clickers that purchase within the attribution window.
- Estimated monthly revenue
- The modeled revenue attributed to email before incrementality, margin, and attribution-overlap adjustments.
Example email campaign revenue calculation
If a brand sends 124,000 emails per month, has a 22% open rate, 8.5% click-to-open rate, 3.2% purchase rate from clicks, and $64 AOV, estimated monthly email revenue is about $4,749. Revenue per 1,000 emails is about $38.30 under the same assumptions.

How to run the email campaign revenue wizard
- On the volume step, input total emails sent per month as delivered sends from your ESP—campaigns, flows, and triggered mail—excluding tests so cadence math matches billing.
- Type average order value from finance-attributed email orders when available; otherwise use blended retail AOV but document coupon leakage so revenue ties to net merchandise.
- On the engagement step, slide unique open rate (%) from opens divided by delivers, click rate on opened (%) as CTOR from unique clicks divided by unique opens, and purchase rate from click (%) as placed orders divided by clicked sessions inside your agreed attribution window.
- Compare estimated monthly revenue and revenue per one thousand emails against last month’s actuals; when wizard outputs diverge, reconcile ESP definitions versus storefront conversion pixels before changing incentives or frequency.
Common email campaign revenue mistakes
- Mixing delivered-email click-through rate with click-to-open rate.
- Including transactional sends while using campaign-only open and click rates.
- Assuming revenue scales linearly with send volume even when list fatigue lowers engagement.
- Using open rate as a quality signal without accounting for Apple Mail Privacy Protection.
- Using blended sitewide AOV when email campaigns use heavy discounts or clearance offers.
- Treating ESP-attributed revenue as incremental without holdout or suppression testing.
- Calling modeled email revenue profit before subtracting discounts, COGS, shipping, returns, and ESP costs.
Broad ecommerce email funnel planning ranges
- Unique open rate on mixed broadcast plus automation sends
- Often ~18–32% on engaged house lists; Apple MPP inflates opens unless cohorts are filtered
- Click-to-open rate (CTOR) on promotional mail
- Commonly mid-single digits to low teens; replenishment flows frequently beat batch sends
- Purchase conversion from clicked sessions (site-side)
- Often ~2–6% for broad promos; VIP or high-intent clicks skew higher when carts already loaded
Best use cases
- Forecasting and scenario planning
- Client education and pre-qualification
- Budget and performance decision support
FAQs
Should monthly emails sent include transactional receipts and password resets?
Only if your open, click, and purchase rates were measured on that same mixed population. Most teams separate transactional templates from marketing sends because CTOR and purchase-from-click differ radically—mixing them warps the funnel unless every rate references the identical denominator.
My ESP labels click rate as percent of delivers, not percent of opens—what breaks?
This wizard expects CTOR (clicks ÷ opens). Convert by multiplying delivered CTR by delivered-to-open ratio, or temporarily set open rate to one hundred percent and plug delivered CTR into the click-on-opened field—document the mapping so month-over-month comparisons stay consistent.
Why is revenue per one thousand emails flat when I only increase monthly sends?
RPM divides attributed revenue by send volume; if engagement rates hold, RPM stays constant while gross dollars rise linearly with sends. RPM drops when fatigue lowers opens or clicks—stress-test sagging rates instead of assuming static CTOR at higher frequency.
Does purchase rate from click include assisted conversions outside the email session?
Only if your analytics tagged those purchases inside the attribution rule feeding this percentage. Tighter windows under-count assisted Shopify checkouts; liberal windows over-credit email when paid social closed the sale—match the wizard to the rule finance accepts for retention reporting.
How do I know if increasing email frequency will actually increase revenue?
Watch revenue per 1,000 emails, unsubscribe rate, spam complaints, click rate, conversion rate, and purchase frequency as frequency rises. More sends can grow revenue short term while lowering engagement and list value if fatigue sets in.
What should I do if opens are high but click and purchase revenue are low?
Audit offer relevance, segmentation, product-market fit, creative clarity, CTA placement, landing page speed, discount depth, and checkout friction. High opens usually mean the subject line worked, but the body or post-click experience did not.
How should I forecast campaigns separately from automated flows?
Run separate scenarios for broadcasts, abandoned cart, welcome, post-purchase, win-back, and replenishment flows. Automated flows often have higher intent and conversion, so blending them with campaigns can hide the real driver of revenue.
How does deliverability change campaign revenue forecasts?
Deliverability affects the reachable audience before opens or clicks happen. If inbox placement drops, revenue can fall even when scheduled send count is unchanged, so monitor delivered rate, spam complaints, bounces, and engaged-list performance.
Should average order value include discount codes from the campaign?
Yes if you want the revenue forecast to match finance results. Use campaign-specific AOV after discounts, or the model may overstate revenue from promo-heavy sends.
How can I improve email campaign revenue without expanding the list?
Improve segmentation, personalize product blocks, test stronger offers, refresh creative, reduce inactive sends, optimize send timing, improve landing pages, and build flows that match customer lifecycle moments instead of relying only on larger audiences.
