Average Cannabis and CBD Email Benchmarks
The cannabis and CBD industry represents one of the most challenging verticals for email marketing due to restrictive ISP policies, evolving legal frameworks, and significant deliverability hurdles. Marketers in this space must navigate a patchwork of regulations that vary by country, state, and even local jurisdiction. Major ISPs including Gmail, Yahoo, and Outlook apply heightened scrutiny to cannabis-related content, often routing bulk cannabis campaigns to spam folders. Age-gating mechanisms are essential, and many email service providers classify cannabis as a restricted or prohibited vertical, limiting platform options.
Despite these constraints, cannabis and CBD email marketing shows strong engagement among subscribers who successfully receive campaigns. Average open rates range from 20% to 28%, which is competitive with or slightly above the all-industry average. Click-through rates fall between 2.5% and 6%, reflecting an engaged subscriber base interested in product education, strain information, and consumption methods. However, bounce rates are notably higher than other industries, frequently running between 3% and 8%, driven by ISP filtering and list hygiene challenges. Spam complaint rates require vigilant monitoring as they can quickly escalate and cause blacklisting.
Key Findings
- Average open rates of 20% to 28%, with higher engagement on educational content about product types and consumption methods.
- Bounce rates of 3% to 8%, significantly above the all-industry average, due to aggressive ISP filtering of cannabis-related content.
- Click-through rates ranging from 2.5% to 6%, with promotional offers and new product announcements driving the highest CTR.
- Approximately 70% of email service providers classify cannabis as a restricted vertical, limiting ESP options for marketers.
- Age-gating and verification mechanisms are essential for compliance and can reduce complaint rates by up to 40%.
Open Rate Benchmarks
Cannabis and CBD email open rates typically range from 20% to 28%, though performance varies significantly by market maturity. Established medical cannabis programmes in countries with legal frameworks, such as Canada and select US states, tend to achieve open rates at the higher end of this range. Educational content explaining cannabinoid profiles, consumption methods, and dosage guidance consistently outperforms purely promotional emails by 4 to 6 percentage points. Subject lines that reference specific product formats, such as edibles, tinctures, or vapes, achieve 2 to 4 percentage points higher open rates than generic brand messaging. Seasonal and holiday campaigns, particularly around 4/20 and other cannabis culture events, can drive open rates above 30%.
Click-Through Rate Benchmarks
Click-through rates for cannabis and CBD emails average between 2.5% and 6%, making this a relatively high-CTR vertical among restricted industries. Product launch announcements and limited-time promotional offers tend to achieve the strongest CTR, often exceeding 5%. Email content featuring educational resources, such as beginner guides to CBD dosing or strain comparison charts, generates CTRs of 3% to 5%. The higher end of the range is reserved for time-sensitive offers and new product drops, where subscriber intent is at its peak. Cart abandonment and back-in-stock campaigns within the cannabis space can achieve CTRs above 8%, mirroring broader e-commerce benchmarks despite the added deliverability challenges.
Best Practices
- Implement robust age-gating on all signup forms, requiring date of birth verification before subscription confirmation to comply with legal requirements.
- Use double opt-in confirmation to build a permission-based list, which helps improve deliverability and reduces spam complaint risk.
- Segment your list by consumption preference, product interest, and geographic location to ensure legal compliance and content relevance.
- Avoid trigger words commonly associated with cannabis marketing in subject lines, such as references to getting high or similar slang, which can trigger ISP filters.
- Monitor deliverability metrics weekly, including inbox placement rates, bounce rates, and spam complaint rates, as cannabis campaigns require more frequent list hygiene.

Frequently Asked Questions
Major ISPs apply heightened scrutiny to cannabis-related content, often flagging legitimate campaigns as suspicious. This results in higher soft bounce rates and occasional hard bounces as providers block emails at the server level. Additionally, many cannabis businesses operate with less established sending reputations, which compounds deliverability challenges.
ESP policies vary considerably. Mailchimp, Klaviyo, and Constant Contact prohibit cannabis-related marketing on their standard platforms. Specialised providers such as Drip, ActiveCampaign, and certain Shopify-integrated solutions may permit CBD and hemp content with restrictions. Full THC product marketing faces the most significant limitations, and some marketers operate their own sending infrastructure.
Markets with clear legal frameworks, such as Canada and states with established recreational programmes, see 3 to 5 percentage points higher open rates and deliverability rates compared to markets with ambiguous or evolving regulations. Recipients in regulated markets also show higher trust in email communications from licensed producers.
Educational content about product types, cannabinoid profiles (THC vs CBD ratios), consumption methods, and dosage guidance consistently outperforms promotional content. Subscribers want to learn about effects, onset times, and appropriate usage before making purchasing decisions, making education a critical component of any cannabis email strategy.
Maintaining a consistent sending volume and frequency helps build sender reputation with ISPs. Implementing authenticated email protocols including SPF, DKIM, and DMARC is essential. Warm up new sending domains gradually over 4 to 6 weeks, and regularly purge inactive subscribers to keep engagement metrics healthy.
