Most vape store owners approach email marketing the same way they approach any other Shopify store. Build a list, set up some flows, send campaigns, track opens and clicks.

Then their Klaviyo account gets suspended. Or their domain gets blacklisted. Or they receive an FDA warning letter because a promotional email did not include a mandated health warning. Or their abandoned cart flow is flagged for targeting users who could not be age-verified.

The vape industry is not like other Shopify verticals. The regulatory environment is specific, the compliance requirements are enforceable with real financial penalties, and the email service provider policies are more restrictive than most founders realise. Get this wrong and the consequences are not just a poor open rate — they are account termination, legal exposure, and potential FTC fines starting at $51,744 per email.

Get it right, and email becomes the single highest-returning channel available to a vape store — because it is one of the few channels where you can still reach your customer directly, without a platform algorithm deciding whether your content is permitted.

Why Email Is Disproportionately Valuable for Vape Stores Specifically

To understand why email matters more for vape than for almost any other Shopify vertical, you need to understand what the alternatives look like.

The Paid Advertising Landscape for Vape in 2025

Meta (Facebook and Instagram) prohibits the promotion of tobacco products, e-cigarettes, vaping products, and related paraphernalia in its advertising policies. This is not a soft guideline — it is an automated enforcement system. Ads are rejected at the creative level, accounts accumulate violations, and repeat offenders face permanent account bans with no appeal process.

Google Ads prohibits advertising of e-cigarettes, vaping products, and related accessories in most geographies, including the United States. This extends to search ads, display ads, and YouTube pre-roll. Some exceptions exist for FDA-authorised tobacco cessation products, but standard vape retail does not qualify.

TikTok prohibits the promotion of tobacco products, e-cigarettes, and vaping devices. Influencer partnerships that promote these products are subject to FTC disclosure requirements and platform enforcement.

The result: the standard paid acquisition playbook that works for most Shopify stores is largely unavailable to vape retailers. This is not a temporary inconvenience — platform policies in this space have become progressively more restrictive since 2019 and there is no regulatory or commercial pressure to reverse that direction.

The Customer Retention Argument

Vape customers are among the highest repeat-purchase customer segments in consumer goods. E-liquid, pods, and coils are consumable products — they run out, and customers need to repurchase on a regular cycle. The average vaper replaces coils every 1–2 weeks and replenishes e-liquid every 2–4 weeks depending on usage frequency.

This purchase pattern makes email — specifically post-purchase flows, replenishment reminders, and loyalty sequences — extraordinarily valuable. You are not trying to convince a vape customer to buy once. You are trying to make sure that when their current supply runs low, they think of your store before they think of Amazon or a competitor.

That is exactly what a well-built email operation does. It maintains presence between purchases, surfaces replenishment signals at the right moment, and builds the brand familiarity that makes your store the default — not the considered choice.

The Compliance Framework: What the Law Actually Requires

This is the section most email marketing guides for vape stores get wrong — either by oversimplifying the requirements or by treating compliance as a footnote rather than a foundational constraint. Here is what the law actually says and what it means for every email you send.

FDA Regulation: The Tobacco Control Act and Deeming Rule

In 2016, the FDA extended its authority under the Family Smoking Prevention and Tobacco Control Act to cover electronic nicotine delivery systems (ENDS) — including e-cigarettes, vaping devices, e-liquids, and all related components. This is called the Deeming Rule.

Under this framework, any promotional email for a nicotine-containing vape product must include the following health warning, displayed prominently:

For nicotine-free vape products, the warning is not required, but any claim that the product is nicotine-free must be accurate and supportable. The FDA’s enforcement of misleading product claims in the vape category has been active and well-documented since 2019.

FTC and CAN-SPAM: The Commercial Email Requirements

Every commercial email sent to a U.S. recipient must comply with the CAN-SPAM Act (Controlling the Assault of Non-Solicited Pornography And Marketing Act, 15 U.S.C. § 7701). The requirements are specific and non-negotiable:

The $51,744 figure is not theoretical. The FTC actively pursues CAN-SPAM violations, particularly in restricted product categories. In 2023 alone, the FTC issued enforcement actions against multiple e-commerce operations in the tobacco and vape space.

Age Verification: The Non-Negotiable Requirement

Federal law prohibits the sale of vape products to anyone under the age of 21. The Tobacco 21 law (signed into federal law in December 2019) applies to all sales channels, including e-commerce. This has direct implications for your email list:

• →Every subscriber on your email list should have completed age verification at the point of sign-up or purchase. An age gate on your Shopify store is the minimum requirement — ideally paired with a third-party age verification service.
• →Sign-up forms must include an explicit 21+ confirmation checkbox. This should be stored as subscriber data in Klaviyo and tagged to the subscriber profile.
• →Email creative must never use imagery, language, or design that could appeal to minors. This is an FDA enforcement standard — “cartoon characters, symbols, role models, celebrities, or any other images that may be particularly appealing to individuals under age 21” are explicitly prohibited in tobacco product advertising.
• →Any purchased or appended email lists are a compliance liability. You cannot verify the age of subscribers you did not acquire through your own age-gated channels. Do not use them.

ESP Policies: Klaviyo’s Position on Vape

Beyond legal compliance, your Email Service Provider has its own acceptable use policy. Klaviyo permits the sending of promotional emails for vape and tobacco products, with specific conditions: the account must be verified, age verification must be documented, and the account must comply with all applicable laws. Violations of Klaviyo’s AUP can result in account suspension — which means losing your entire automation infrastructure, list, and sending history overnight.

Keep a documented record of your compliance measures — your age verification process, your FDA warning implementation, your opt-in consent records — and store it separately from Klaviyo in case you ever need to demonstrate compliance during an account review.

Building a Compliant, High-Quality List

For vape stores, list quality matters more than list size. This is true for all email marketing — but it is especially true here, where a single non-age-verified subscriber who makes a complaint can trigger regulatory attention.

The Only Acceptable Acquisition Methods

Given the age verification requirement, there are effectively three compliant list-building approaches for U.S. vape stores:

What Not to Do: The List-Building Mistakes That Create Legal Exposure

The Klaviyo Flow Architecture for Vape Stores

The flow structure for a vape store follows the same foundational logic as any Shopify email operation — but with specific modifications at every stage to address the compliance requirements, the consumable purchase cycle, and the restricted paid acquisition environment.

Flow 1: Welcome Series — The Compliance-First Onboarding Sequence

The welcome series for a vape store has an additional job beyond brand introduction and first-purchase conversion: it needs to establish the compliance context from the first touchpoint. This does not mean leading with legal language — it means building the brand’s credibility, authority, and transparency in a way that differentiates you from the grey-market operators your customers have likely encountered.

The educational middle email is particularly important for vape. Customers in this category — especially those transitioning from traditional cigarettes — have real questions about device selection, nicotine strength, coil maintenance, and flavour differences. An email that answers those questions without selling anything builds the kind of authority that drives long-term loyalty. It also reinforces responsible use messaging, which is both commercially sensible and regulatory-aligned.

Flow 2: Abandoned Cart — The Highest-Intent Recovery Flow

Abandoned cart for vape operates the same way as any other category — someone added a product and left without completing purchase. The recovery logic is identical. The compliance addition: every email in the abandoned cart sequence that references a nicotine-containing product must include the FDA health warning.

Flow 3: Replenishment Flow — The Vape-Specific Revenue Engine

This is the flow that most vape stores do not have — and the one that matters most given the consumable nature of the product category.

The replenishment flow triggers a set number of days after a purchase, based on the expected consumption rate of the product purchased. A customer who buys a 30ml bottle of 3mg e-liquid will consume it at a different rate than a customer who buys a 100ml bottle of 6mg. A customer who buys a 5-pack of replacement coils will run out at a different time than someone who buys a single coil.

In Klaviyo, this is implemented using product-specific flow triggers and conditional time delays:

Flow 4: Post-Purchase — Loyalty, Upsell, and Review Collection

The post-purchase window is where customer lifetime value is built. For vape stores, the post-purchase sequence has three specific jobs:

Job 1 — Onboard the product. If a customer just bought their first device, they need to know how to use it correctly. An email with setup instructions, coil priming guidance, and troubleshooting tips reduces returns, reduces support tickets, and dramatically increases the probability that the customer has a positive first experience — which is the primary driver of a second purchase.

Job 2 — Introduce the consumable ecosystem. A customer who bought a device needs coils, e-liquid, and eventually replacement pods or batteries. The post-purchase sequence is the correct place to introduce these complementary products — not as a hard sell, but as a natural extension of helping the customer get the most from what they already bought.

Job 3 — Collect a review. Social proof is the primary trust signal in vape e-commerce, where customers cannot physically sample products before purchasing. A review request sent 10–14 days after purchase — when the customer has had enough time to form a genuine opinion — generates the kind of specific, product-level reviews that convert future buyers.

Flow 5: Win-Back — Recovering Lapsed Customers

For vape stores, a customer who has not purchased in 60 days is a significant signal — given the consumable nature of the products. At the 60-day mark, most vaping customers should have repurchased at least once. If they haven’t, they are either buying from a competitor or they’ve stopped vaping.

The win-back sequence for vape should address both possibilities: a compelling offer for those who switched to a competitor, and a re-engagement question for those who may have changed habits. The tone should be direct and non-pushy — a genuine “we noticed you haven’t been back, here’s why we think you should” rather than a desperation discount.

Campaign Strategy: What to Send, When, and to Whom

Flows generate automated, behaviour-triggered revenue. Campaigns generate scheduled revenue around specific moments. For vape stores, the campaign calendar follows a different rhythm than general e-commerce — it is less tied to standard retail holidays and more tied to product launches, seasonal flavour releases, and loyalty milestones.

The Four Campaign Types That Work for Vape

1. New flavour or product launch campaigns. The vape customer is a product explorer by nature. New e-liquid flavours, new device generations, and new pod system launches are high-engagement content for this audience. A launch campaign should lead with the product story — what makes this flavour different, what inspired it, what the flavour profile is — before the call-to-action. Product education converts better than promotional urgency in this category.

2. Seasonal flavour campaigns. The vape industry has a genuine seasonal flavour pattern — menthol-forward products in winter, fruit profiles in summer, dessert-inspired flavours in autumn. Mapping your campaign calendar to flavour seasonality generates more relevant sends than generic promotional blasts and gives your content team a clear creative brief each month.

3. Loyalty and VIP campaigns. Vape stores have naturally high repeat purchase rates — but most do not formalise this into a loyalty structure. A VIP segment (customers who have purchased 3+ times or spent above a threshold) that receives early access to new products, loyalty-exclusive discounts, and priority customer support creates the kind of retention engine that is extremely difficult for a competitor to dislodge.

4. Re-engagement campaigns for browse abandonment. Someone who views a product page but does not add to cart is showing purchase intent. For vape stores where the product discovery process is genuinely complex — device compatibility, nicotine strength selection, flavour preference — browse abandonment emails that answer the likely question behind the hesitation (“not sure which nicotine strength is right for you? Here’s the guide”) convert at meaningfully higher rates than generic “you looked at this” reminders.

Segmentation Rules That Change Campaign Performance

The single most impactful segmentation decision for a vape store campaign is separating the list by product type preference. An e-liquid buyer and a device buyer have completely different purchase cycles, different product interests, and different content needs. Sending the same campaign to both reduces relevance and drives unsubscribes from whichever segment the content was not designed for.

The Pre-Send Compliance Checklist

Every campaign and every flow email for a vape store should pass this checklist before scheduling. This is not optional — it is the minimum standard for a compliant email operation in this category.
