Most dispensary owners know that email marketing and SMS marketing drive revenue. What they don't know is exactly how much revenue their list should be generating — and whether the money they're spending on platforms, agencies, and content is producing a worthwhile return. Without clear ROI projections, marketing budgets get cut during slow months, programs get paused prematurely, and operators miss the compounding gains that come from consistent execution.
This calculator solves that problem. Input your list size, send frequency, average order value, and conversion rates, and it will project your monthly and annual revenue from email and SMS — plus your ROI against a typical managed program cost. The default values are drawn from 2026 cannabis industry benchmarks, so even if you're just exploring, the numbers reflect real dispensary performance data.
Why You Need to Calculate Email & SMS ROI
Running an email and SMS program without tracking ROI is like running a dispensary without looking at your POS reports. You might feel like things are going well, but you have no way to know whether your marketing dollars are producing a return or burning cash. Here's why the math matters.
- Budget justification. When ownership asks whether the $2,500/month marketing spend is worth it, you need a number — not a feeling. ROI calculations give you a concrete answer: "For every dollar we spend, we generate X dollars in revenue." That's the kind of answer that protects budgets during slow quarters.
- Benchmark setting. If you don't know what good performance looks like, you can't identify problems. An ROI calculator built on industry benchmarks tells you whether your 12% email conversion rate is strong or weak relative to other dispensaries your size.
- Channel allocation. Email and SMS have different cost structures, different conversion rates, and different revenue profiles. Calculating ROI for each channel separately tells you where to invest more and where to pull back. Most dispensaries under-invest in SMS relative to its performance.
- Growth planning. Want to know what happens if you grow your email list from 5,000 to 10,000? Or increase send frequency from 2 to 3 emails per week? The calculator models these scenarios so you can plan growth with confidence instead of guesswork.
Email & SMS ROI Calculator
Enter your dispensary's numbers below. The defaults reflect 2026 cannabis marketing benchmarks for dispensaries with active, opted-in lists managed through platforms like Alpine IQ. Adjust any field to match your operation.
Your Inputs
How the math works: Monthly email revenue = (list size x sends per week x 4.33) x (conversion rate / 100) x average order value. SMS uses the same formula with monthly sends directly. ROI = (total monthly revenue - monthly cost) / monthly cost. These are projections based on industry benchmarks — your results will vary based on list quality, content strategy, and segmentation. Pair this with our customer LTV calculator for a complete picture of your marketing economics.
The Benchmarks Behind the Calculator
The default values in this calculator aren't arbitrary. They're drawn from the 2026 Cannabis Email Marketing Benchmarks Report and aggregated data from dispensary programs we manage through our email and SMS marketing service. Here's what the data shows.
- 18% email conversion rate. This is the percentage of email recipients who make a purchase within a 5-day attribution window after receiving a marketing email. It accounts for both click-to-purchase and in-store visits driven by email. Dispensaries with strong segmentation see 20-24%. New or unsegmented lists typically start at 12-15%.
- 22% SMS conversion rate. SMS consistently outperforms email on conversion rate because of its immediacy and near-universal open rates (95%+). The tradeoff is smaller list sizes and higher per-message costs. Dispensaries with well-timed SMS campaigns — especially flash sales and restock alerts — regularly exceed 25%.
- $65 average order value. This is the national median for dispensary transactions in 2026. Markets like New York and New Jersey tend higher ($75-$90), while more mature markets like Colorado and Oregon trend lower ($50-$60). Use your actual AOV from your POS data for the most accurate projection.
- 2 emails per week, 4 SMS per month. This is the optimal frequency for most dispensaries. More than 3 emails per week increases unsubscribe rates without proportional revenue gains. SMS tolerance is lower — more than 6 per month drives opt-outs. Our SMS marketing guide covers frequency optimization in depth.
How to Improve Each Input Metric
The calculator shows you where you are. This section shows you how to move each lever to increase your projected revenue. Small improvements across multiple inputs compound into significant revenue gains.
Growing Your List Size
List size is the foundation. A larger list means more potential conversions on every send. The most effective dispensary list-building tactics in 2026 include point-of-sale opt-in prompts during checkout, loyalty program enrollment, website popup forms with first-purchase incentives, and in-store signage with QR codes. Dispensaries that actively build their list add 300-800 subscribers per month. Dispensaries that don't actively build see net list shrinkage due to natural churn.
Increasing Conversion Rates
Conversion rate is the highest-leverage input in the calculator. Moving email conversion from 15% to 20% increases revenue by a third — with no additional list growth or sends required. The keys to higher conversion are segmentation (sending relevant offers to specific customer segments), personalization (using purchase history to recommend products), and timing (sending when your customers are most likely to buy). Platforms like Alpine IQ make this segmentation straightforward.
Raising Average Order Value
AOV improvements affect every channel simultaneously. Effective tactics include bundling products in email promotions, highlighting premium product categories, offering tiered discounts (spend $100+ to save 15%), and featuring high-margin accessories and edibles alongside flower promotions. A $10 increase in AOV across thousands of monthly conversions adds up fast. Check our retention guide for strategies that lift both AOV and repeat purchase rates.
What Good ROI Looks Like
If you're running a managed email and SMS program — whether in-house or through an agency — here are the ROI benchmarks that separate underperforming programs from strong ones.
A dispensary spending $2,500/month on a managed program should expect $20,000-$30,000 in monthly attributed revenue at maturity. Programs typically take 60-90 days to reach full performance as automations are built, segments are refined, and the cadence stabilizes. The first month is rarely representative of long-term ROI.
Programs that consistently fall below 5x ROI usually have one of three problems: the list is too small (under 2,000 combined email and SMS contacts), the content isn't segmented (every subscriber gets the same message), or attribution tracking isn't set up correctly — meaning the revenue is happening but isn't being measured. Before cutting a program, rule out measurement problems first.
Common ROI Measurement Mistakes
Even dispensary operators who track ROI often get the measurement wrong. These mistakes either inflate your numbers (giving false confidence) or deflate them (causing you to kill a profitable program). Avoid all six.
- Not tracking attribution at all. The most common mistake. If you're sending emails and SMS without tracking which orders they drive, you have no ROI data — just a cost line on your P&L. Every marketing platform worth using offers attribution tracking. Turn it on. Without it, you're flying blind.
- Counting opens as conversions. An open is not a sale. Open rates tell you about subject line performance and deliverability, not revenue. The metric that matters is conversion rate: the percentage of recipients who actually make a purchase. Some platforms default to showing open-based metrics prominently — look past them to the revenue data.
- Using too wide an attribution window. A 30-day attribution window will credit your email program for purchases that would have happened regardless. A 3-5 day window is more accurate for dispensary marketing because cannabis purchase cycles are short. If a customer buys 3 weeks after receiving an email, that email probably wasn't the driver.
- Ignoring list health costs. A list that's 40% inactive subscribers inflates your denominator and suppresses your conversion rate. The cost of maintaining dead contacts — platform fees are often tiered by list size — should be factored into your ROI calculation. Regular list cleaning improves both your conversion rate and your cost efficiency.
- Conflating gross and net revenue. Revenue driven by a 20% discount promotion has a different margin profile than revenue driven by a new-product announcement. If your ROI calculation doesn't account for discount depth, you might be overstating the profitability of your program. Track net revenue (after discounts) for the most accurate picture.
- Measuring too early. Email and SMS programs compound over time. Automated flows like retention sequences, welcome series, and win-back campaigns build revenue that doesn't exist in month one. Evaluating ROI after 30 days is like judging a dispensary's viability based on opening week. Give the program 90 days before making budget decisions.
Frequently Asked Questions
What is a good ROI for dispensary email marketing?
Dispensaries with a well-managed email program typically see 8-15x ROI on their marketing spend. That means for every $1 invested in email marketing — agency fees, platform costs, content creation — the dispensary generates $8-$15 in attributed revenue. Programs that also incorporate SMS tend to land at the higher end of that range because SMS conversion rates run 20-25% higher than email alone.
How do you calculate email marketing ROI for a dispensary?
The formula is: (Revenue attributed to email - Cost of email program) / Cost of email program x 100. Revenue attributed to email includes all orders placed through email links within a defined attribution window (typically 3-5 days). Costs include your marketing platform subscription, agency fees if applicable, and any SMS message fees. Most dispensaries find their all-in cost runs $1,500-$3,500 per month, while attributed revenue ranges from $15,000-$50,000+ depending on list size.
Are the conversion rates in the calculator realistic?
The default conversion rates of 18% for email and 22% for SMS are based on 2026 cannabis industry benchmarks for dispensaries with active, opted-in lists. These represent the percentage of recipients who make a purchase after receiving a marketing message within a 5-day attribution window. New programs or lists with poor hygiene may see lower rates initially, while mature programs with strong segmentation often exceed these benchmarks.
How much does dispensary email and SMS marketing cost?
A fully managed dispensary email and SMS program typically costs $2,000-$4,000 per month with an agency, which includes strategy, content creation, segmentation, automation setup, and reporting. Platform fees for tools like Alpine IQ run an additional $200-$500 per month. SMS message fees add $0.01-$0.03 per message. For a dispensary sending 2 emails and 4 SMS messages per week to a combined list of 8,000, total monthly cost is typically $2,500-$4,500.
The Bottom Line
Email and SMS marketing are the highest-ROI channels available to dispensaries — but only if you're measuring correctly and optimizing against real benchmarks. The calculator above gives you a starting point. The educational content on this page gives you the context to interpret the numbers and the playbook to improve them.
If your projected ROI falls below 8x, focus on the input metrics: grow the list, tighten segmentation to lift conversion rates, and optimize promotions to raise AOV. If you're already above 10x, you're in strong territory — the next step is scaling list size and send frequency to multiply that return.
