# Klaviyo: pricing, features and plan guide
Businesses choosing a broader email marketing platform where signup forms feed customer profiles, segmentation, and automated follow-up. Cost grows with the contact list.

- **Who is this app for?** Businesses choosing email marketing and customer segmentation, with signup forms feeding the same customer profiles and automated flows.
- **Main advantage:** Forms sit alongside customer data and email automation. Free already supports getting started; paid email expands list capacity.
- **Main limitation:** The bill grows with active profiles and channel usage. A simple site notice alone does not justify adopting the full platform.
## Pricing and plans
Klaviyo prices email by active profiles and SMS separately by credits. A paid email subscription is not required just to create a signup form. A growing active list or an additional channel can change the bill without changing the form itself. Choose paid Email for the required messaging capacity rather than simply for access to signup forms.
Starting prices from Shopify. Larger lists and extra channels change the total; SMS is not included in the $20 Email price.
**Why Email is a Papa pick:** The paid Email tier makes sense as the list outgrows Free or requires more sending capacity. Do not upgrade just for a popup: Free already includes signup forms and automation within its limits.
| Plan | Price | Limits | What changes |
| --- | --- | --- | --- |
| Free | Free | Up to 250 contacts | Forms · Segmentation · Automation |
| Email (Papa pick) | $20.00/mo | 251–500 contacts | More email capacity |
| SMS | $15.00/mo | 1,250 SMS/MMS credits | Separate SMS subscription |

## Features and plan access
Klaviyo puts signup forms beside customer profiles, segments and email flows. Multi-step forms and A/B tests support acquisition, while welcome flows act on the collected subscription. CAPTCHA and double opt-in address suspicious traffic and subscription confirmation respectively.
Free already includes forms and automation within its limits. The paid Email tier is a capacity choice as the list or sending needs grow, not the price of unlocking a basic popup. SMS carries separate costs, and the wider platform should be evaluated for its customer-data and messaging workflow.

## Formats & content
A standalone message without a form or action button is not confirmed, so Announcements is not credited. The web-form template library includes an Announcement popup category. This is an onsite message format, separate from an email campaign; the documentation also provides popup dismissal and frequency settings.
Use the onsite announcement format separately from an email broadcast. Dismissal and frequency settings help control repeat exposure, but the subscription follows profiles and channel usage rather than a simple popup display quota. A notice alone is a different buying case from adopting Klaviyo for segmentation and ongoing messaging.

## Gamification
Klaviyo’s game formats include spin the wheel. Klaviyo sign-up forms include a spin-to-win wheel with 2 to 6 slices; each slice has its own probability and gets its own success step and coupon. The game is the way an offer is revealed; prize configuration and the signup flow determine what the visitor actually receives. Compare the available formats, reward controls and repeat-play rules before choosing a mechanic for a promotion.

Klaviyo’s testing tools include A/B testing. Sign-up forms can be A/B tested with up to 7 variations, an even or weighted traffic split and automatic winner selection. Popup testing, email testing and automation experiments are separate capabilities. A useful comparison also considers traffic allocation, how a winner is selected and whether a no-popup control is available to measure the effect of showing a campaign at all.

## Email & SMS
Klaviyo’s messaging channels include email marketing and SMS marketing. Create email campaigns, segments and automated flows. Sending and profile limits depend on the plan. Run SMS campaigns and flows; availability and messaging costs depend on the destination. Capturing an address in a popup and sending a marketing campaign are separate jobs. Compare native sending channels, automation and their allowances independently from the popup subscription; an integration with a mailing platform does not include that platform’s sending service.

## Team & sites
Klaviyo supports multiple users with predefined roles such as Admin, Manager, Analyst, Support, Campaign Coordinator and Content Creator, plus custom roles built from view, export, edit and publish permissions. Only Owners and Admins edit billing.
Portfolio groups multiple accounts for management rather than turning them into one popup subscription. For agencies, evaluate account access and channel charges together. A teammate who prepares content may not need the same authority as someone managing billing or customer data.

## Developer
Klaviyo’s developer interfaces include HTTP API, browser API, webhooks, and MCP server. A remote OAuth MCP server (and a local API-key option) exposes tools for campaigns, flows, profiles and reporting, with read-only and scope restrictions. A REST API with private API keys and OAuth covers forms (create, update, publish, read), campaigns (create, send), profiles, flows and reporting, with per-key scopes.

## Support
Paid plans include email support and live chat on weekdays, with weekend hours depending on the plan. Free accounts get email support for their first 60 days, then the help centre, academy and community. Consider the support channel alongside the work you expect help with. Access to chat does not by itself promise round-the-clock coverage, a response deadline or someone to build your campaigns. Those service commitments need to be distinguished from ordinary product assistance.

## Editor & workflow
Klaviyo’s editing tools include free editor and campaign drafts. Forms have Draft, Live and Editing statuses; a draft is not live on the site. The Free plan includes web forms and the drag-and-drop editor. Editing, saving a draft and activating a campaign are separate stages of the workflow. Consider how changes are prepared and reviewed before visitors see them. An AI writing assistant also has a narrower role than an assistant that can change layout or targeting.

## Data & reporting
Klaviyo’s data and reporting tools include lead export, scheduled reports, and revenue goals. Form responses are exported by building a segment of people who submitted the form and exporting it to CSV. Custom reports can be scheduled weekly or monthly; Klaviyo emails a download link to the user who set the schedule.

## Integrations
Klaviyo is usually the destination for store and customer data. Commerce connections supply profiles and orders; partner apps add events used in segmentation and flows. Native forms already collect into Klaviyo, so an integration catalogue entry should not be mistaken for a direct export of popup leads to another mailing platform.
Native signup forms feed Klaviyo itself. A marketplace listing is not proof of two-way sync, a free partner account or a native Google Sheets export; check the individual connector.
Our [integration guide](https://popuppapa.com/popup-integrations/index.md) explains the connection types and workflows.
| Connection | Services | Data |
| --- | --- | --- |
| CRM (+0.84) | Salesforce · Zoho · Pipedrive · Microsoft Dynamics | Sync leads and custom properties with CRM platforms. |
| CRM (—) | HubSpot | A HubSpot route is listed in the integration marketplace. Check the individual connector’s direction, partner subscription and supported properties before using it to deliver signup-form leads. |
| Customer lifecycle (+0.84) | Gorgias · Recharge · Zendesk · Intercom · Smile · LoyaltyLion · Yotpo · Stamped | Klaviyo and partner-built apps supply additional customer events. These are wider-platform connections, not all popup-specific. |
| Advertising (+0.83) | Meta Advertising · TikTok Advertising · Google Ads · Pinterest · Snapchat | Sync audiences and events with advertising platforms. |
| Store (+0.83) | Shopify · WooCommerce · BigCommerce · Adobe Commerce · PrestaShop · Salesforce Commerce Cloud · Wix | Bring store customer and order data into Klaviyo. Supported data and sync frequency differ by platform. |
| Reviews (+0.83) | Judge.me · Loox · Okendo · REVIEWS.io · Junip | Bring review events and data into segments and flows. |
| Automation (+0.83) | Shopify Flow · Zapier | Connect Shopify Flow and Zapier workflows to Klaviyo. |
| Custom connections (—) | REST API · SDKs · Webhooks | Build a custom connection for profiles, events and other supported resources; flows can call a webhook. |

## Works with Shopify
Klaviyo’s Shopify coverage includes storefront installation, native app, discounts, and customer data. Klaviyo generates unique Shopify discount codes for forms and flows, and records discount codes used on orders. Bring Shopify customer and order data into Klaviyo. Installation, customer data, discounts and cart actions are separate capabilities. A Shopify listing alone does not establish support for all of them, and features supplied by a separate app need to be considered with that app’s access and pricing.

| --- | --- | --- |
| Storefront installation (+0.88) | Supported | A native Shopify app is available. |
| Native app (+0.88) | Supported | A native app is available in the Shopify App Store. |

## Capability score
The capability score brings together the confirmed features in the sections above, excluding pricing. Each metric belongs to one section, and a feature’s score includes its subfeatures. The breakdown shows how much each area contributes and where points remain unearned. It measures feature coverage, rather than conversion performance or value for money.
68.66 out of 100 for confirmed capabilities, excluding price. Each metric is counted once; its score includes its subfeatures. Unconfirmed capabilities earn no points.

## AI agent readiness
Agent readiness looks at a complete working process: understanding a campaign, creating or changing it, operating it, reading results and controlling access. This assessment adds context to the Developer section without awarding extra points. In-editor AI assistance and an external agent’s ability to operate the account are considered separately.
**Creates and publishes forms through its API.** Klaviyo is well exposed to agents: a Forms API creates draft forms and publishes them, a Reporting API returns form performance, scoped API keys and OAuth limit access, and an official MCP server covers campaigns, flows, profiles and reporting with a read-only mode. In-product AI builds campaigns, flows and segments and reviews existing forms.
| Agent interface | Available | What it offers |
| --- | --- | --- |
| In-app AI | Not confirmed | Composer can create campaigns, flows and segments from plain-language goals; its documented form capability is reviewing an existing sign-up form for conversion blockers. |
| REST API | Yes | REST API with a Forms API to create draft forms, update and publish them, read them and query form performance. |
| MCP | Yes | Remote MCP server over OAuth plus a local server with a private API key; supports read-only mode and API-scope limits. |
| Browser API | Yes | The klaviyo JavaScript object identifies visitors, tracks events and opens forms; forms emit klaviyoForms window events. |
| Webhooks | Not confirmed | Flow webhook actions POST payloads to an endpoint; system webhooks via API are restricted to Advanced KDP customers and app partners. |
| Agent task | Status | What the agent can do |
| --- | --- | --- |
| Understand | Supported | Forms API reads form definitions and versions, and the Reporting API returns form performance. |
| Create | Partial | The Forms API creates draft forms from an encoded definition; A/B tests are set up in the editor. |
| Operate | Supported | Forms can be published and unpublished through the API, and campaigns can be created and sent. |
| Measure | Supported | Reporting API returns campaign, flow, form and segment values (scopes forms:read, campaigns:read). |
| Work safely | Supported | Private API keys have custom, read-only or full scopes; the MCP server supports read-only mode and scope-limited toolsets; forms are created as drafts. |
Private API keys (Owner, Admin or Manager can manage them) with read-only, full or custom scopes, or OAuth. The remote MCP server requires an Owner, Admin or Manager role; no plan requirement is documented. Flow webhooks require multi-factor authentication.

## What one display or signup could cost
At $20.00 per month, the selected plan allocates $0.020 per display and $1.00 per signup across 1,000 displays and 20 valid email signups. The table rounds to cents. The 2% signup rate is an assumption, not measured performance or a vendor charge per event.
The capacity check assumes one site and 250 billable contacts. Billing is based on active profiles and email sends, which is distinct from the actual outcomes used here. For form-free announcements, compare displays rather than signups. Taxes, separately billed services and customer discounts are excluded.
| Outcome | Calculation | Estimated cost |
| --- | --- | --- |
| One display | $20.00 ÷ 1,000 | $0.02 |
| 1,000 displays | $20.00 ÷ 1,000 × 1,000 | $20.00 |
| One signup | $20.00 ÷ 20 | $1.00 |

## Klaviyo alternatives: which should you choose?
Businesses choosing email marketing and customer segmentation, with signup forms feeding the same customer profiles and automated flows. The bill grows with active profiles and channel usage. A simple site notice alone does not justify adopting the full platform.
Compare Omnisend and Getsitecontrol against that requirement. The cards below explain where each is a better fit. Match the billing unit, required features and site or account limits before comparing headline prices; the cheapest subscription does not always cover the same work.
### Klaviyo vs Omnisend
At 500 contacts, Klaviyo Email starts at $20/month and Omnisend Standard at $16 with 6,000 sends. Choosing between them also means choosing the data and automation workflow behind the forms.
- **Choose Omnisend:** When its ecommerce flows cover the job at the lower starting subscription.
- **Choose Klaviyo:** When customer profiles and segmentation in Klaviyo already drive the marketing operation.
[Omnisend review](https://popuppapa.com/reviews/omnisend/index.md)
### [Klaviyo vs Getsitecontrol](https://popuppapa.com/klaviyo-vs-getsitecontrol/index.md)
Getsitecontrol Pro is $19/month per site for popup campaigns and 100,000 displays; email costs extra. Klaviyo’s $20 starting Email tier is a contact-based marketing subscription.
- **Choose Getsitecontrol:** When the immediate job is announcements and promotions on the site.
- **Choose Klaviyo:** When signup forms should feed the same customer profiles used for ongoing email automation.

## About this review
Popup Papa compares published pricing, product documentation and help articles. This is a documentation-based review, not a hands-on performance test. Dates beside sources indicate when the corresponding evidence was checked; publication does not imply that every source was rechecked that day.
“Documented” means the provider describes the capability. A named plan is shown only where we recorded tier evidence. “Not confirmed” means the evidence is insufficient, not that the feature is absent. Paid add-ons and higher-tier restrictions are stated separately. Conflicting billing information prevents a unit-cost estimate.
Recommendations are editorial judgments about fit and cost. Sources are linked next to the claims they support, and every calculation uses the assumptions above.
