At a glance
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.
All-in-one SEO and online visibility toolkit
Semrush is an online visibility and marketing platform best known for search engine optimisation. It provides keyword research, competitor analysis, site auditing, rank tracking, backlink data, content tools and advertising research, used by marketers, agencies and businesses to grow organic and paid search traffic. Its breadth is the defining feature. Where some tools specialise in one aspect of SEO, Semrush covers most of the workflow in one subscription. The Keyword Magic Tool and keyword gap analysis find search terms and opportunities competitors rank for; Domain Overview and Traffic Analytics estimate any site's traffic, top pages and sources; Site Audit crawls a website for technical issues; Position Tracking monitors rankings by location and device; and the Backlink Analytics database shows linking domains. Content tools help plan topics and optimise articles, and local SEO features manage business listings and reviews. Semrush has expanded beyond SEO into a broader marketing toolkit. Advertising research reveals competitors' paid search keywords and ad copy, social media tools schedule and analyse posts, and market research features analyse industries and audiences. In response to AI search, it has added tools that track how brands appear in AI assistants and answer engines and recommend ways to improve visibility. An app centre offers additional specialised tools. Semrush is a paid subscription with tiers by number of projects, tracked keywords and users, and a free account with limited queries. The main criticisms are cost, especially for small businesses and when adding users and add-ons, and the reality that third-party traffic and keyword estimates are approximations rather than exact data. Alternatives include Ahrefs, its closest competitor, particularly strong in backlink data; Moz Pro, with its Domain Authority metric; SE Ranking and Mangools for more affordable suites; Similarweb for market and traffic intelligence; Screaming Frog for technical crawling; Surfer for content optimisation; and Google Search Console for free first-party data. Choose Semrush when you want one comprehensive toolkit for SEO, competitor research and search advertising.
