CPM Calculator vs Klaviyo: the short verdict
CPM Calculator and Klaviyo are both listed under Marketing on Launchory, which is why founders weigh them against each other: CPM Calculator describes itself as “Free advertising calculators for CPM, spend, impressions, CPC, CTR, and eCPM”, Klaviyo as “Email and SMS marketing for e-commerce”. On cost, CPM Calculator is the cheaper way in — it is listed as free to use, while Klaviyo keeps a permanent free tier.

All of that comes from what each product records on Launchory — category, pricing model and tags — not from hands-on testing.
At a glance
Free advertising calculators for CPM, spend, impressions, CPC, CTR, and eCPM.
CPM Calculator is a free browser-based toolkit designed for advertisers, marketers, publishers, media buyers, freelancers, and small businesses that need to plan and evaluate digital advertising campaigns. The main calculator lets users enter any two values among CPM, total ad spend, and impressions, then instantly calculates the missing value. This makes it easy to estimate campaign costs, compare media plans, and check whether a proposal fits an available budget. The website also includes focused calculators for CPC, CTR, eCPM, break-even ROAS, campaign reach, campaign comparison, and YouTube earnings. Each calculator explains the formula, shows the result immediately, and keeps the workflow simple for users who do not want to build spreadsheets or search for formulas. The tools are useful for planning new campaigns, reviewing past performance, comparing advertising channels, and communicating estimates with clients or teammates. CPM Calculator works directly in the browser and does not require an account, installation, or subscription. Users can select a currency label, enter their campaign data, and receive results without hidden currency conversions or unnecessary steps. The responsive interface works on both desktop and mobile devices. Unlike a large advertising platform, CPM Calculator is independent of any particular advertising network. It focuses on transparent calculations and practical planning tools that can be used across display advertising, social media campaigns, video advertising, publisher inventory, and other paid media channels. All core calculators are free to use.
Email and SMS marketing for e-commerce
Klaviyo is a marketing automation platform for email, SMS and other channels, built primarily for e-commerce brands. It combines customer data from online stores with tools to segment audiences, automate personalised messages and measure revenue generated by each campaign. Its defining strength is data. Klaviyo integrates deeply with platforms such as Shopify, WooCommerce, BigCommerce and Magento, syncing every customer's browsing behaviour, orders, products viewed, cart contents and lifetime value in near real time. Marketers can build segments such as "bought twice but not in the last 90 days" or "viewed a product in this category but did not buy" and send precisely targeted messages, which tends to outperform generic newsletters for online stores. Automated flows are where much of its revenue impact comes from: welcome series, abandoned cart and browse abandonment reminders, post-purchase follow-ups, replenishment reminders, win-back campaigns and back-in-stock alerts. Predictive analytics estimate each customer's next order date, likely lifetime value and churn risk, and AI features help write content, build segments and optimise send times. Klaviyo has broadened into SMS, push notifications, reviews, customer service tools and a customer data platform, positioning itself as a full B2C marketing system. The company is publicly listed. Klaviyo offers a free plan for small lists and paid plans priced by number of active profiles and messages, which can become expensive as a list grows. Its depth also brings a learning curve, and its value is clearest for e-commerce rather than for B2B companies or simple newsletters. Alternatives include Omnisend for e-commerce email and SMS at lower cost; Mailchimp for general small-business marketing; Attentive and Postscript for SMS-focused marketing; Braze and Iterable for enterprise cross-channel engagement; Drip for e-commerce automation; and Shopify Email for basic, built-in campaigns. Choose Klaviyo when you run an online store and want data-driven email and SMS automation that drives measurable revenue.
