Email and SMS marketing ROI is the revenue your campaigns generate measured against what they cost to send.
What is the Email & SMS Marketing ROI Calculator?
This free email and SMS marketing ROI calculator projects the revenue and return from your owned channels. Because you already own the audience, email and SMS typically return many times their cost, making them one of the most profitable levers in ecommerce.
How this calculator works
Enter your list size, sends per month, the click rate, the conversion rate of those clicks, your average order value, and your monthly tool cost. The calculator estimates orders and revenue, then compares revenue to cost to produce ROI and revenue per send.
How to read your result
The headline is your estimated monthly revenue from email and SMS. The rows show messages sent, orders generated, ROI, and revenue per send. Automated flows like welcome, cart recovery, and post-purchase usually outperform one-off campaigns, so prioritise them.

Frequently asked questions
What is a good email marketing ROI?
Email regularly returns tens of dollars for every dollar spent, with ecommerce benchmarks often cited around 36 to 42 dollars per dollar. SMS and well-built automated flows can push it higher.
How is email ROI calculated?
Estimate revenue by multiplying sends by click rate, conversion rate, and average order value, then subtract cost and divide by cost. This calculator does it for you and also shows revenue per send.
Should I include automated flows?
Yes. Flows like welcome, abandoned cart, and post-purchase often drive a large share of email revenue from a small share of sends, so they dramatically improve overall ROI.
