Klaviyo vs Drip for Shopify Brands: Read the Meter Before the Feature List

Klaviyo and Drip are both ecommerce-first email platforms with Shopify integrations and behavior-based workflows. Klaviyo bills on active profiles and adds SMS, WhatsApp and push; Drip bills on active people from $39 a month with unlimited email sends and no SMS channel. The meter, more than the feature list, decides how each marketing team spends its week.

We build neither, so read this as informed but interested. Both platforms are described in their own words, including where each beats us on its own terms. The argument about the meter is ours, and it ends somewhere neither of them goes.

Where Drip wins

• A flat, all-in price. Drip’s pricing page starts at “$39” a month for “1-2,500 people” with “Unlimited email sends,” and its comparison page puts it plainly: “What you see at $39/month is what you get at $289/month.” Its pricing page frames the deal as paying for “your list size and how many emails you send. Not for features you never use.”
• Workflow triggers and goals. Drip lists “Multiple triggers per Workflow” and “Workflow Goals” that “stop automation immediately when purchase fires” as things it does and Klaviyo does not. For a team that runs many entry points into one sequence, that is fewer flows to maintain.
• Migration done for you. “For lists of 17,500 contacts or more, Drip handles your migration for free,” which it scopes to rebuilt email templates, migrated contacts and tags, and core workflows set up before the trial ends, plus “90 days of personalized onboarding support.”
• Trial and support. A 14-day trial with no card, email support on every paid plan, and live chat on plans of $99 a month and up, in its own words. Drip also ships an MCP connector so you can query your account from Claude or ChatGPT at no extra cost.

Where Klaviyo wins

• Channels. Drip’s own comparison concedes it: “Klaviyo wins on multichannel breadth,” with native SMS, WhatsApp and push notifications. Drip lists “Global SMS service as a channel” as something it does not offer.
• Shopify depth and defaults. Klaviyo is the platform the Shopify ecosystem assumes: agencies, apps and hires know it.
• Ecommerce AI and education. Klaviyo’s pricing page names K:AI and a Customer Agent, and its free tier includes Klaviyo Academy courses, community and documentation.

The honest read on each. Drip’s weakness for a Shopify brand is the missing SMS channel and a smaller customer base (Drip says it is “Trusted by 6,000+ brands”), which matters as soon as SMS is part of the plan. Klaviyo’s weakness is the meter and the price that follows it, which is the whole of Drip’s pitch. Neither is a defect. Each is the shape of the product.

The meter is the decision: list hygiene as a budget line

Both platforms price on people. Klaviyo’s pricing page counts profiles; Drip’s pricing FAQ says “Your cost is based on the number of active people in your account and the volume of emails you send during the month.” Drip’s page says both: the plan card lists “Unlimited email sends” and the FAQ counts the volume sent. Either way, the unit is people. The difference is the curve: Drip publishes a flat, all-in price per band, while Klaviyo layers channels and tiers on top of the profile count. What they share is more important than what separates them. When the bill counts people, cleaning the list stops being a deliverability chore and becomes a finance decision, and the marketing team’s week bends toward the meter: who to suppress, when, and what it costs to keep a lapsed subscriber another cycle.

That is a strange thing for a marketing team to spend its time on, and it is a direct consequence of what the products are. A tool a person operates has to be priced on something a person can count, and contacts and sends are the countable things. Drip’s honest pitch, that its meter is flatter and kinder, is still a pitch about the meter. The question worth asking is whether the meter should exist, which is a question about what the software does rather than what it charges.

What both share: a person designs every workflow

Under the two builders, a Drip workflow and a Klaviyo flow are the same architecture. A trigger fires, a delay runs, a message goes out, a branch splits on a condition someone defined in advance. Drip gives the designer more entry points and a goal that stops the sequence sooner; Klaviyo gives the designer more channels and deeper store data. In both, the decision about who receives what, and whether they receive anything, was made weeks earlier by a person in a builder. When results plateau, the answer in both tools is another workflow and another test, and the meter ticks either way.

The alternative: no builder, because no person runs it

Relvino has no flow builder, because the decisions are not made by a person. It runs the loop Observe → Decide → Act: it watches live shopper signals from the store, decides for that one shopper whether a message is warranted at all, then the offer, timing and channel, in about 80 milliseconds, and executes across email, SMS and on-site. Guardrails are set once, including margin floors, channels and brand voice, and inside them 100% of flows run without a human in the loop. Pricing is published in full at pricing and runs 3–7× cheaper than Klaviyo.

The engine is a Large Retail Model trained on 7M+ data points across 10K+ retailers and 1.78M shoppers, so it arrives with priors about a category instead of learning a store from zero. Brands leaving Klaviyo see 3× ROI in 30 days and 4× revenue uplift year over year; across incumbents the range is 2–6× ROI in 30 days and up to 10× revenue uplift year over year. Susan Jit, founder of Sulina Shop, put the meter question this way: “My old email tool charged a flat fee no matter what. Relvino focuses on highly targeted sends with fewer emails and a higher return.” Sulina Shop saw 4× ROI. Fewer emails is the tell: an agent that decides whether to send at all sends less, and a per-contact meter has nothing to charge for.

So which should you choose?

If SMS is part of the plan, or the brand leans on the Shopify ecosystem’s agencies and apps, Klaviyo’s breadth earns its meter, and the price is the cost of the default. If the brand is email-first on Shopify, WooCommerce or BigCommerce, wants one flat number and would rather have someone else rebuild the flows during the switch, Drip is the cleaner bill and its migration offer is real. In both cases a person will design and maintain every workflow, and the list will be pruned on a schedule set by the invoice.

The third case is the common one at $20–100M GMV: the flows are built, the list has been cleaned twice, and the numbers have been flat for three quarters. A flatter meter does not move that. Run a 14-day pilot beside whichever you have and compare revenue directly. For the wider field, Klaviyo competitors maps every lane, Klaviyo vs ActiveCampaign covers the automation-and-CRM alternative, and Klaviyo pricing reads the meter in detail.

Frequently asked questions

Who are Klaviyo's main competitors?

In Shopify and DTC ecommerce, Klaviyo competes with Omnisend, Mailchimp, Drip, Sendlane and Brevo on email, and with Attentive and Postscript on SMS. Drip competes most directly on price, positioning itself as the flat-rate ecommerce alternative. Upmarket Klaviyo meets Braze, Iterable and Salesforce Marketing Cloud. Relvino competes on a different axis, replacing the flow stack with autonomous decisioning rather than offering another builder.

What are the top 3 email marketing tools?

For a Shopify brand the three most often shortlisted are Klaviyo, Mailchimp and Omnisend, with Drip the usual pick when a flat, all-in price matters more than channel breadth. All are builders in which a person designs every workflow. The other kind of tool is autonomous decisioning, such as Relvino, which replaces the builder with per-shopper decisions inside guardrails and is judged by a side-by-side pilot rather than a feature grid.

What are the weaknesses of Klaviyo?

Set against Drip, three stand out. The meter: Klaviyo bills on active profiles, with channels and tiers layered on top, so list growth is a standing cost whether or not those people are mailed. Drip’s comparison lists a “Free migration service with personalized onboarding” as something it offers and Klaviyo does not. And Drip’s comparison lists “Multiple triggers per Workflow” and “Workflow Goals” that “stop automation immediately when purchase fires” as things it offers and Klaviyo does not. Its deeper weakness, shared with Drip, is that it sells a builder, so results improve only when a person improves them.

Why is Klaviyo so expensive?

Because of what it counts. Klaviyo prices on active profiles and layers SMS, WhatsApp and plan tiers on top, so the bill rises with the list whether or not those people are mailed, and cleaning the list becomes the way to control cost. Drip’s answer is a flatter meter on the same unit. The structural answer is a platform that decides per shopper whether to send and sends less; Relvino runs 3–7× cheaper than Klaviyo on that basis.

How long does it take to migrate from Klaviyo to Relvino?

The technical cutover takes about 30 minutes: authenticate the sending domain, install the Shopify app, and historical data ingests on its own. Nothing is rebuilt, because there are no flows to recreate, which is the difference from a Drip migration, where the workflows are rebuilt in a builder by Drip’s team. Revenue runs on a different clock: run a 14-day pilot with Klaviyo paused rather than cancelled, and compare the two side by side before deciding.
