We highlight the main differences and pick a winner for each feature.
Kit offers powerful visual automations for complex sequences. Square offers simpler, set-and-forget automations.
Kit (formerly ConvertKit) lets you build visual automation maps for welcome series, sales funnels, and nurture sequences. You can connect multiple steps and conditions for granular control. One creator reported 30% sales growth from a targeted automation. Square Marketing provides automated campaigns for welcome emails, birthday wishes, and lapsed customer reminders. Setup is a one-time process. It's designed for simplicity, not complex branching logic. The key difference is depth versus ease. Kit is for building intricate, personalized journeys. Square is for sending reliable, recurring messages with minimal setup.
Square has a deep, integrated CRM with purchase history. Kit uses basic tagging for audience segmentation.
Kit (formerly ConvertKit) uses tags and segments to organize subscribers. You can add or remove tags based on actions, but it doesn't store detailed transaction history. Focus is on email engagement. Square Marketing integrates with the Square Customer Directory. This free CRM automatically syncs with your POS. It tracks every customer's purchase history, visit frequency, and spending across all locations. For a local business, Square's data is a game-changer. You can target customers based on what they actually bought, not just what they clicked.
Kit is email-only. Square Marketing combines email and high-impact text messages.
Kit (formerly ConvertKit) is a pure email platform. It helps you send newsletters, broadcasts, and automated sequences. There's no native SMS or text messaging feature built in. Square Marketing offers both Email Marketing and Text Message Marketing as separate, integrated services. Texts have a 98% open rate. You can send flash sales, appointment reminders, or cart recovery texts directly. The ability to combine email and text campaigns gives Square a significant edge for time-sensitive promotions. Kit remains focused on owned email audiences.
Kit lets you sell digital products directly. Square is designed to drive sales to your existing store.
Kit (formerly ConvertKit) allows you to sell digital products, courses, and subscriptions through its platform. It handles checkout and delivery. You own the entire customer relationship from lead to sale. Square Marketing doesn't sell products itself. Instead, it promotes your existing Square store. It drives traffic with coupons and tracks redemptions. It connects marketing spend directly to POS revenue. The choice depends on your business model. If you're a creator selling digital goods, Kit is a storefront. If you're a retailer, Square is a promotional engine.
Kit provides email performance metrics. Square provides sales attribution across all channels.
Kit (formerly ConvertKit) shows open rates, click rates, and subscriber growth. The Pro plan adds a deliverability dashboard. Reporting is focused on email engagement metrics. Square Marketing syncs campaign data with sales data. You can see which email or text campaign led to a coupon redemption and a specific transaction in your Square Dashboard. It measures real revenue impact. For marketers, Kit's metrics are essential. For business owners, Square's sales attribution is more valuable for calculating ROI.
Both are user-friendly, but Kit is for marketers. Square is integrated for business owners.
Kit (formerly ConvertKit) has a clean, intuitive interface praised by creators. It simplifies email building and automation for non-technical users. The learning curve is gentle. Square Marketing is built directly into the Square Dashboard. If you already use Square, there's no new software to learn. The tools are straightforward for sending basic campaigns. Both avoid complexity. Kit excels at marketing tasks. Square excels at being part of a business management system you already use daily.
Kit offers a generous free plan. Square's value depends on your contact list size.
Kit (formerly ConvertKit) has a free plan for up to 10,000 subscribers. Paid plans start at $39/month. This is excellent value for growing an audience from zero. Square Marketing's Email service starts at $15/month for up to 500 contacts. Price scales up with more contacts. Text Marketing has a $10 base fee plus per-message costs. Kit provides more features at the entry level. Square's pricing is straightforward but costs more as your customer list grows significantly.
Kit has no review collection feature. Square automates Google Review requests.
Kit (formerly ConvertKit) focuses entirely on email communication and audience growth. It does not offer tools to solicit or manage online reviews. Square Marketing includes an automated feature to send campaigns requesting Google Reviews after a purchase. This happens via email or text at no extra cost. This built-in reputation tool is a major advantage for local businesses. It helps build social proof automatically, a feature Kit doesn't attempt to match.
