A 2026 buyer’s guide to Klaviyo, Dotdigital and Attentive. Pricing verified October 22, 2026.

The brands we sit down with at this stage are almost always asking the same question in different words: they started on a simple, inexpensive tool while the business was small, and now they are wondering whether the switch is worth the disruption. This is close to the conversation we walk a growing brand through in their first strategy session with us, priced and compared honestly rather than sold, and it runs about eight minutes end to end. By the end you will know what a genuine migration actually costs in hours and interrupted sends, which platform fits a brand doing real monthly revenue through this channel, what each of the three really costs once a list or a contract minimum is applied to it, and how to tell whether you have actually outgrown your current tool or just feel like you have.

What this guide covers

• What switching platforms actually costs, in hours and lost sends, and why that number belongs in the decision from the start.

• The signals that mean you have genuinely outgrown a starter tool, and the ones that are just noise.

• What the regulators require of email and text at this size, and why consent records matter more than contact records in a migration.

• Klaviyo, Dotdigital and Attentive, each assessed the same way: pricing, our read, the vendor in its own words where it has given us them, and who it suits.

• A side-by-side table, then a recommendation for the size and shape of correspondence your brand is actually running.

• The questions growing brands ask us most often about making this move without losing a season of sends.

The short version. A brand doing meaningful monthly revenue through email, meaning real automation, segmented campaigns, and a list that behaves like a revenue channel rather than a newsletter, is generally best served by Klaviyo, whose published ladder still opens at $20 a month for 500 active profiles and climbs in visible steps you can model against your own list before you sign anything. Dotdigital earns serious consideration once a brand wants cross-channel orchestration handled alongside a dedicated account team rather than through self-serve tooling, and its Shopify listing now gives a floor to plan around, with plans from $187 a month. Attentive remains the strongest specialist for a brand where text already carries real weight, though it says plainly that it is built for mid-market and enterprise ecommerce, works only on annual contracts with a $10,000 yearly minimum, and is not the right fit below roughly 30,000 monthly site sessions.

Whether you have actually outgrown your starter tool

The clearest signal is not list size on its own, it is whether your current platform can already answer questions your team is asking of it. A brand that wants to send a different message to someone who bought once versus someone who has bought five times either can do that today or cannot, and if the platform cannot, no amount of list growth changes that answer. A second signal, often the more expensive one, is a support team spending hours a week working around a starter tool’s limits with manual tagging or spreadsheet exports, real labor that never shows up as a line item on the software bill itself.

The order-volume thresholds referenced throughout this guide describe a brand doing roughly 1,000 orders a month, which is where most vendors’ own pricing tiers cut and a reasonable in-article marker for mid-market, generally understood as $2 million to $50 million in annual revenue. These thresholds are directional rather than absolute, and a brand with a lower order count but a genuinely premium average order value can justify a mid-market platform well before the order count alone would suggest it, since the value recovered from each abandoned cart or win-back campaign scales with price point rather than volume. Do not let a volume rule of thumb talk you out of a platform your margins can clearly support, and equally, do not let a vendor’s enterprise case studies talk you into a contract minimum your traffic cannot yet carry.

Migration itself is the cost most founders underestimate. Moving a list, its tags, its segmentation logic, and its automation flows to a new platform is rarely a weekend project; it typically runs several weeks of real work once testing and QA are included, and sends are usually reduced or paused during that window to avoid duplicate or broken messages reaching customers. A brand doing meaningful monthly revenue through email loses real money during that pause, which is why choosing correctly the first time, or moving early rather than late, matters more here than almost anywhere else in a lifecycle stack.

What the regulators actually require, and why it matters more at this size

The rules do not change as a list grows, but the exposure does, since a larger list means a compliance mistake reaches more people and draws more attention. The Federal Trade Commission’s compliance guide to the CAN-SPAM Act requires a working opt-out mechanism for at least thirty days after a message is sent, requires every opt-out request to be honored within ten business days, and requires the sender’s valid physical postal address to appear in the message itself, with civil penalties and consumer redress both possible for violations.

Text carries a stricter standard still. The Federal Communications Commission’s rules, codified at 47 CFR 64.1200 in the Code of Federal Regulations, require prior express written consent before a marketing text reaches a mobile number, and they specify that a reply of “stop,” “quit,” “cancel,” or “unsubscribe” is an automatic revocation the sender must honor without requiring confirmation. A brand migrating platforms needs to confirm that consent records, not just contact records, transfer intact, since a platform that imports email addresses cleanly but drops the timestamped consent history behind them has quietly created a compliance gap that only surfaces during an audit or a complaint. Every vendor in this guide sells tooling for consent capture, opt-out handling and quiet hours, and that tooling supports a compliance program without replacing the brand’s own legal review, a distinction worth holding onto however reassuring the sales deck sounds.

What actually separates these three platforms

How much of the migration the vendor actually helps with. Some platforms offer a dedicated onboarding team to rebuild flows and segments during a switch, and some leave that work to the brand or its agency, and the difference shows up directly in how many weeks the transition takes.

Whether pricing is published or negotiated. Klaviyo publishes a full calculator that scales with active profiles and meters text by the message. Dotdigital publishes a floor on its Shopify listing and quotes everything above it, and Attentive publishes its pricing logic but not its rates, building each deal around program size, contract length and bundling, which rewards a brand that walks in with its own numbers.

How deep cross-channel orchestration goes. A brand at this size increasingly wants a single program logic governing email and SMS together rather than two calendars that happen to share a customer list. Klaviyo and Dotdigital both build genuine cross-channel journeys from a shared profile; Attentive’s heritage sits in text, with email now sold alongside it and leaning on identity resolution to connect the two.

How the contract is shaped. Month to month, annual by choice, or annual by rule changes the risk of trying a platform considerably, and at this stage it deserves as much weight as the headline rate.

What level of support comes with the price. A starter tool sells software; a mid-market platform increasingly sells a relationship, with a named account contact and deliverability monitoring bundled into the higher tiers. Confirm what tier that support starts at before assuming it comes free with the base price quoted on a sales call.

Klaviyo

Metered by active profiles for email, with text billed per message on top. Shopify, plus WooCommerce, BigCommerce and headless. 4.7 stars from 3,405 reviews on the Shopify App Store.

Klaviyo is the platform most growing Shopify brands end up on, and its pricing page explains why with unusual candor: a free plan, a paid email tier at the same $20 it has held for some time, and a calculator that shows exactly what the next few thousand profiles will cost before they arrive.

Pricing

Verified October 22, 2026 against Klaviyo’s own pricing calculator and its Shopify App Store listing; the calculator was read at each profile step shown, and Klaviyo was running a limited offer of $19 off the first month of the 500-profile Email plan at the time of writing. The September version of this guide showed a bundled Email plus SMS plan at $35, which the pricing page no longer presents, so text should now be modeled as a metered add-on rather than a bundle.

Our read

Klaviyo’s real advantage for a growing brand is that the same data model powering its entry tier scales cleanly into genuinely sophisticated segmentation without a platform change, which is precisely the migration cost this guide keeps returning to. A brand that already knows its customers by purchase history, browse behavior and predicted next order date can act on that data in a flow rather than a report, the text side of the platform shares the same profile record rather than treating SMS as a bolted-on afterthought, and the calculator means a finance lead can see the bill at 5,000 profiles and at 25,000 before anyone commits.

What it asks in return is attention to the profile count. The ladder is gentle at the bottom and steeper in the middle, moving from $100 at 5,000 profiles to $400 at 25,000, and because Klaviyo bills on active profiles, a list that swells after a giveaway or an import can push an account into a higher step faster than revenue follows, which is the single complaint that recurs most often in its App Store reviews. Suppressing unengaged profiles is therefore part of running Klaviyo well, not an optional tidy-up, and text costs should be modeled on real send volume because they no longer arrive as a neat bundle.

Who it suits

Most brands moving off a starter tool, particularly those that want self-serve control, a transparent price they can model against their own list, and email and text reading from one customer record, and that are willing to keep the list clean so the profile count tracks the customers who actually matter.

Dotdigital

Plans from $187 a month on its Shopify listing, quoted above that, sold with an account team. Shopify, Magento, BigCommerce and wider CRM connections. 4.5 stars from 21 reviews on the Shopify App Store.

Dotdigital is built for the brand that wants strategy alongside the software, and since its July rebrand it sells three connected products, marketing automation, personalization and a new loyalty and retention layer, rather than an email tool with extras.

Pricing

Verified October 22, 2026 against Dotdigital’s Shopify App Store listing, which states plans from $187 a month with monthly or annual options after a 14-day trial. Dotdigital’s own site still publishes no pricing page; both dotdigital.com/pricing and its page sitemap were checked the same day, so everything above the entry plan should be treated as a quote to negotiate rather than a published rate.

Our read

Dotdigital’s case for a growing brand rests less on price and more on the account relationship that comes with it, since the platform is built for a team that wants strategic guidance alongside the software rather than a self-serve dashboard alone. Its cross-channel automation is genuinely strong for brands running email and SMS as a single coordinated program rather than two separate calendars, and its data connections make it a comfortable fit once a stack has grown past a handful of simple integrations. The published floor is a meaningful change since September, because a brand can now hold $187 against Klaviyo’s calculator and see that the comparison begins somewhere around the 7,000 to 10,000 profile mark rather than at the first dollar.

The tradeoff is that everything beyond the floor still lives on a call, which makes an apples-to-apples comparison harder to run without picking up the phone, and a brand still doing a few hundred orders a month will likely find both the starting price and the sales-assisted process heavier than the tool it is replacing warrants. Its review base on Shopify is also small, so there is less collective operating knowledge to lean on than with the category leader.

Who it suits

Brands with a list that has already outgrown the lower steps of a self-serve ladder, a team that would rather have a named account contact shaping cross-channel strategy than run everything alone, and an interest in pulling personalization and loyalty into the same platform as their sends.

Attentive

Annual contracts only, with a $10,000 yearly minimum and custom rates built around program size, contract length and bundling. Shopify and other ecommerce platforms. 4.7 stars from 112 reviews on the Shopify App Store.

Attentive made its name in text and now sells email alongside it, leaning on identity resolution that connects shopper behavior across touchpoints and AI personalization meant to make each message more relevant at a scale a small team could not manage by hand.

Pricing

Verified October 22, 2026 against Attentive’s own pricing page, which explains the model without publishing rates, its Shopify App Store listing, which offers a minimum 30-day free trial followed by long-term agreements, and base rates supplied directly by Attentive. Attentive notes that each deal receives custom rates, so the figures above are ceilings and starting points rather than a quote.

Our read

Attentive’s advantage is depth rather than breadth, since a brand doing serious text volume benefits from carrier relationships, deliverability expertise and compliance tooling that a generalist builds as a secondary feature, and its identity work, recognizing a returning shopper who has not logged in, is exactly what makes a triggered message land on the right person. For a brand where SMS already drives a meaningful share of lifecycle revenue, that specialization is worth the negotiation it takes to reach a fair rate.

The contract is the decision, though. At $10,000 a year committed and annual terms only, Attentive is a commitment of roughly $833 a month before the program proves itself, and the vendor’s own fit line, which places the threshold around 30,000 monthly site sessions, is a more honest qualifier than most sales teams volunteer. Below that traffic, a growing brand will usually get more from a self-serve platform’s text add-on and revisit Attentive when the numbers arrive, ideally walking into that conversation with its own volume and revenue figures rather than accepting the first rate offered.

In their words

By Attentive’s own account it is a strong fit for mid-market and enterprise ecommerce brands looking to grow email and SMS revenue through deliverability, identity resolution that connects shopper behavior across touchpoints, and AI-powered personalization at scale. It is direct about who should look elsewhere: brands outside ecommerce, and brands seeing fewer than 30,000 monthly site sessions. It also describes its consent collection and records, opt-out handling, litigator removal and quiet-hour controls as support for a brand’s compliance program and its own legal review rather than a removal of legal risk.

“Technology that can autonomously make decisions and personalize messages for marketers at scale is where the real value is.” Eric Miao, Chief Executive Officer, Attentive

Asked about working with us, Attentive’s team wrote: “I appreciate that Atelier tailors its recommendations to each brand’s stage of growth, helping merchants figure out what makes sense for them now and what they’ll need as they scale.”

Eric Miao

Chief Executive Officer, Attentive

Who it suits

Ecommerce brands already past roughly 30,000 monthly sessions, where text carries real revenue weight, a year-long commitment of at least $10,000 is comfortable, and identity resolution and AI personalization will be put to work rather than admired. It is not for non-ecommerce brands or for a brand still building the traffic to justify it.

The verdict, by reader

If you are moving off a starter tool because your list has started to behave like a revenue channel and you want a transparent, self-serve price ladder you can model against your own list size, Klaviyo is the right move, and a $20 entry point makes the switch a small line item relative to what disorganized correspondence is already costing you in missed recovery, provided you keep the active profile count honest as the list grows. If your list has passed the lower steps of that ladder and your team would rather have a named account contact managing cross-channel strategy alongside the software, hold Dotdigital’s $187 floor against Klaviyo’s calculator at your actual profile count and get a quote before assuming the self-serve option is automatically the better value, since the account relationship often replaces work you would otherwise hire for separately. If text already drives a meaningful share of your revenue, your site is comfortably past 30,000 monthly sessions, and a year at $10,000 or more is a planned investment rather than a stretch, Attentive is worth the extra step of negotiating a custom contract rather than settling for a generalist platform’s SMS add-on.

Questions we get asked

How do I know if I have actually outgrown my starter email platform?

The clearest sign is a specific capability you want today that the platform cannot do at all, such as segmenting a flow by real purchase history, rather than a vague sense that you should be doing more.

How long does a real email platform migration take?

Plan for several weeks once list transfer, flow rebuilding, and testing are included, with sends typically reduced during the transition to avoid duplicate or broken messages reaching customers.

Is it worth switching platforms mid-quarter?

Generally no, since the reduced-send window during migration costs more during your busiest periods; plan the move for a genuinely quiet stretch on your calendar whenever the business allows it.

Why don’t Dotdigital and Attentive publish pricing like Klaviyo does?

Both price around a brand’s specific volume, channel mix and contract, so neither publishes a full ladder; Dotdigital now shows a starting price of $187 a month on its Shopify listing, and Attentive sets a $10,000 annual minimum with custom rates above it.

Does a bigger list always justify a bigger platform?

Not on its own; average order value matters as much as list size, and a smaller, higher-value list can justify a mid-market platform before order count alone would suggest it.

What happens to my consent records during a migration?

A responsible migration carries timestamped consent history over with the contact record itself, and this should be confirmed explicitly with any new vendor before the switch, not assumed.

Should I negotiate a quote-based platform’s price, or accept the first number?

Negotiate, and bring your own volume, revenue, and growth projections to that conversation, since both Dotdigital and Attentive price around exactly those numbers and Attentive states that every deal receives custom rates.

Where to go next

If you would rather have this migration planned and executed by people who have done it before than learn the pitfalls yourself, our email and SMS marketing service covers platform selection, migration, and ongoing send strategy. For how this plays out once a brand has made the move, see our story on building a lifecycle program that kept paying off, and on turning a newsletter into a brand’s number one revenue channel. If loyalty is part of the roadmap alongside this move, our loyalty and rewards page covers how the two typically launch together, and if the sign-up experience on the site itself needs work before the list can grow, our conversion rate optimization practice handles that half.
