SMS is the fastest revenue channel in cannabis retail. When a well-crafted text hits a customer's phone at 11am on a Tuesday, you can watch foot traffic increase within the hour. No other marketing channel delivers that speed of response.
But most dispensaries are leaving this channel's potential on the table. They're sending generic blasts to unverified lists with no segmentation, no strategy, and copy that reads like a spam folder. The result is high unsubscribe rates, poor open rates, and a sense that "SMS doesn't work for us."
It works. You just have to build it correctly.
Why SMS Works Differently Than Email
Email is deliberate. Customers open it when they're ready to engage. SMS is immediate, it interrupts whatever they're doing and demands a glance. That immediacy is both the power and the responsibility of the channel.
With a 98% open rate and a median open time under 3 minutes, SMS reaches customers in a way no other channel can match. A well-timed message about a same-day flash sale, a vendor special, or a low-point loyalty reminder generates visits that simply would not happen otherwise.
The key distinction: Email builds relationships over time. SMS drives immediate action. Your SMS program should be built around creating urgency, limited-time offers, same-day specials, and timely loyalty triggers. If the message could wait a week, it probably belongs in email.
Compliance First, Always
SMS marketing is governed by the TCPA (Telephone Consumer Protection Act), which carries fines up to $1,500 per unsolicited message. In cannabis, you also layer state advertising regulations on top of federal law. This is not an area to improvise.
The non-negotiable compliance requirements for dispensary SMS:
- Express written consent is mandatory. Every subscriber must actively opt in, pre-checked boxes and implied consent do not meet TCPA standards. Your platform should capture and log this consent with a timestamp.
- Age verification before any send. All SMS subscribers must be 21+ verified. This is both a compliance requirement and a platform policy on Alpine IQ and SpringBig.
- Every message must include opt-out language. "Reply STOP to unsubscribe" is required on at minimum every campaign message. Most platforms handle this automatically.
- No health claims. Cannabis SMS advertising follows the same rules as all cannabis advertising, no therapeutic claims, no medical language, no curative assertions.
- Quiet hours apply. Federal law prohibits SMS marketing before 8am or after 9pm in the recipient's local time zone. Platforms should enforce this automatically, but verify your settings.
Building Your Opt-In Flow
The quality of your opt-in flow determines the quality of your subscriber list, and your subscriber list determines everything that follows. High-performing dispensary opt-in flows share three characteristics: they make it easy, they make it valuable, and they make it explicit.
In-Store Keyword Opt-In
The simplest and most effective opt-in method: customers text a keyword to a short code to join your list. "Text DEALS to 55555 for exclusive offers and loyalty rewards." Train your budtenders to mention this at every transaction and display it prominently at the register, on menus, and in your waiting area.
Web Opt-In
A phone number field on your online menu, website contact form, or loyalty signup page captures customers who find you online. This is a smaller but highly engaged segment, they sought you out, which means they're already motivated.
Loyalty Enrollment
Every loyalty signup should capture a mobile number with explicit SMS consent checked separately. Loyalty subscribers have the highest SMS engagement rates of any segment, they joined specifically to get value from your program.
Message Cadence: How Often Is Too Often
The fastest way to destroy an SMS program is to over-send. Unlike email, where a subscriber might ignore a message they don't want, SMS recipients who feel spammed unsubscribe immediately and permanently. Once they're gone, they're gone.
The cadence that works for most dispensaries:
- 2 to 3 campaign messages per week maximum for your general list
- Daily during major cannabis holidays (4/20 week, Green Wednesday), subscribers expect and welcome higher frequency during these periods
- Automated triggers are separate from campaign cadence, birthday messages, win-backs, and loyalty reminders don't count against your weekly volume limit
- Never send more than once per day under any circumstances
Timing matters as much as frequency. The highest-performing send windows for dispensary SMS are Tuesday to Thursday between 10am to 12pm and 3pm to 5pm. Avoid Monday (low engagement), Friday evening (people have plans), and weekend mornings (sleep in). Test your own audience's patterns after 60 to 90 days of data.
What to Send: Content That Converts
SMS has a 160-character limit for standard messages, though most platforms support longer messages via MMS or concatenated SMS. Regardless of length, effective dispensary SMS follows the same formula: urgency, value, and a clear action.
Flash Sales and Daily Specials
A same-day percentage-off offer with a clear expiration creates immediate urgency. "Today only: 20% off all vapes. In-store only, today until close." Simple, direct, and trackable via POS data.
Vendor Features
Brand partner or vendor in-store that day? An SMS to your list before noon drives afternoon traffic. "Brand rep from [Brand] is in our [Location] store today 12 to 6. Ask about their new line + get 15% off."
Loyalty Triggers
Automated messages tied to loyalty milestones, "You're 50 points away from your $10 reward", drive visits that wouldn't otherwise happen. This is incremental revenue generated by customers who are already predisposed to visit.
Product Launches
New product hitting your shelves? Your SMS subscribers should hear about it before anyone else. Exclusivity ("SMS subscribers get first access") increases opt-in rates and reduces opt-outs among existing subscribers.
Segmentation: The Difference Between Good and Great
Sending the same message to your entire list is leaving money on the table. The dispensaries generating $10+ per send are segmenting their lists and sending targeted messages to the right customers at the right time.
The segments that matter most for dispensary SMS:
- Purchase frequency, Weekly regulars, monthly visitors, and lapsed customers should receive different messages with different offers
- Product preference, Flower customers don't want edibles promotions. Alpine IQ and SpringBig both allow POS-linked segmentation by purchase history
- Loyalty tier, VIP members should feel like VIPs. Give them early access, better offers, and exclusive communications that feel different from the general list
- Location, For multi-location operators, messages should be location-specific. A promotion at your Brooklyn store shouldn't go to your Westchester customers
Building It vs. Doing It Right
Setting up an SMS program takes an afternoon. Building one that consistently generates $10+ per send takes strategy, ongoing management, and continuous optimization. The platform will send whatever you put in it, what you put in it is everything.
The operators we work with hand us the keys: we manage the list, write the copy, segment the sends, monitor the metrics, and optimize based on what the data shows. The result is a program that runs without consuming the operator's time and generates revenue every week it operates.
If your current SMS program isn't generating measurable, trackable revenue per send, let's look at what's holding it back.
