Overview
Sendy and ConvertKit serve completely different markets. Sendy is for technical users who want to minimize costs through self-hosting. ConvertKit is for creators who want a polished platform with monetization built in. The choice often comes down to who you are.
Different Users, Different Needs
Sendy targets technical senders who prioritize cost savings. ConvertKit targets creators who want to build audience-based businesses. A developer sending newsletters chooses differently than a blogger building a paid community.
Sendy's Cost Advantage
At 10,000 subscribers, Sendy costs $1-5/month (just Amazon SES fees). ConvertKit costs $119/month. Over a year, that's $1,300+ in savings. At larger list sizes, savings grow proportionally. If pure cost matters most, Sendy wins.
ConvertKit's Creator Features
ConvertKit has paid newsletters, digital product sales, tip jars, beautiful landing pages, and the Creator Network for cross-promotion. These features can generate revenue that exceeds the platform cost. Sendy has none of this.
Technical Reality
Sendy requires server administration. You need PHP/MySQL hosting, Amazon SES setup, and ongoing maintenance. ConvertKit is sign-up-and-start. For non-technical creators, Sendy isn't really an option.
Email Design Philosophy
ConvertKit intentionally uses minimal, text-focused email design. The theory is that personal-looking emails perform better for creators. Sendy has dated templates. Neither is ideal for visual marketing, but they're different kinds of not-ideal.
For SaaS Companies
Neither platform is built for SaaS. Sendy lacks modern automation. ConvertKit lacks Stripe integration for subscription businesses. For SaaS companies wanting payment-triggered emails, consider Sequenzy.
Making the Choice
Choose Sendy if you're technical, sending basic newsletters, and want to minimize costs. Choose ConvertKit if you're a creator wanting monetization tools and audience growth features. For SaaS companies, consider Sequenzy.
