Email is the one channel no ad ban can take away, but three rule sets stack on it: CAN-SPAM for email, the TCPA for texting, and your platform's acceptable-use policy. Mainstream ESPs shut down THC senders, so pick a platform that wants your business before you build the list.
CAN-SPAM applies to every cannabis email
Federal email law does not care that your product is state-legal. It applies to any commercial email, and the core duties are simple: a truthful subject line and from-name, your physical postal address in every send, a working unsubscribe link, and opt-outs honored within ten business days. None of this is hard. Skipping it hands regulators and spam-trap operators an easy case against a sender who already looks risky on paper.
Texting runs on TCPA consent
SMS is the highest-ROI channel most dispensaries run, and the easiest to get wrong. The TCPA requires prior express written consent before marketing texts: an unchecked box the customer actively ticks, records you keep, and STOP requests honored immediately. Carriers also filter cannabis SMS aggressively, which is one more reason to use a platform built for the industry rather than pushing traffic through a generic gateway.
Your platform's policy matters more than you think
Mailchimp and Klaviyo both restrict cannabis senders under their acceptable-use policies, and enforcement usually arrives as a sudden account suspension, not a warning. Losing your ESP mid-campaign means losing automations, templates, and send history overnight. Cannabis-native platforms such as Springbig and Alpine IQ were built for dispensary loyalty and messaging and will not drop you for being what you are. Whatever you use, export your list on a schedule — the list is the asset, the platform is rented.
Build a 21+ list from day one
Collect an age attestation, or a date of birth, at signup and keep it with the record. Marketing age-restricted products to a list you never age-screened is exactly the kind of gap state regulators ask about. It also protects deliverability: engaged adult customers open and click, while mystery signups rot your sender reputation.
Deliverability is now a compliance job too
Google and Yahoo require bulk senders to authenticate with SPF, DKIM, and DMARC, offer one-click unsubscribe, and keep spam complaints under roughly 0.3 percent. Cannabis senders start with less margin for error, so warm up new domains slowly, prune dead subscribers, and keep health claims out of subject lines — "relieves pain" is a problem for both the FDA and the spam filter.
What this looks like in practice
A dispensary welcome flow done right: signup form on the website with an unchecked 21+ attestation box, hosted on Springbig or Alpine IQ. Email one sends store hours, directions, and a first-visit offer, with the street address and unsubscribe link in the footer. SMS enrollment is a separate, clearly labeled written-consent step, never bundled into the email checkbox. Every message that promotes product is identified as marketing, and STOP or unsubscribe takes effect the moment it arrives.
Key takeaways
- CAN-SPAM and the TCPA apply fully to cannabis; the industry gets no exemption and no slack.
- Mailchimp and Klaviyo can suspend THC senders; Springbig and Alpine IQ are built for them.
- Age-screen the list at signup and export it regularly; the list is the asset.
Frequently asked questions
Can I use Mailchimp for a dispensary?
Their acceptable-use policy restricts cannabis senders, and accounts get suspended without much warning. Some CBD senders slip through; THC retail generally does not. A cannabis-native platform costs less than rebuilding a program after a shutdown.
Does CAN-SPAM really apply to cannabis email?
Yes. It covers all commercial email regardless of product legality: truthful headers, a physical address, a working unsubscribe honored within ten business days. Treat it as the floor, not the ceiling.
What consent do I need to text customers?
Prior express written consent under the TCPA: an affirmative, unchecked opt-in that you record, separate from email consent. Honor STOP immediately and keep proof of every opt-in.
Does email help SEO?
Indirectly and meaningfully. It sends returning visitors to your site, distributes new content that can earn links, and keeps revenue flowing when an algorithm update or platform policy cuts other channels.
