Overview

Sendy and Mailchimp represent opposite ends of the email marketing spectrum. Sendy is a $69 self-hosted application that sends through Amazon SES for rock-bottom costs. Mailchimp is a full-featured SaaS platform with 20+ years of development. See our Mailchimp comparison for more context.

The Cost Question

This comparison ultimately comes down to one question: how much is your time worth? Sendy can save you thousands per year at scale, but requires technical skills and ongoing maintenance. Mailchimp costs more but handles everything for you.

Sendy's Massive Cost Advantage

At 100,000 emails/month, Sendy costs roughly $10 (just Amazon SES fees). Mailchimp would charge $350+ for similar volume. Over a year, that's $4,000+ in savings. At higher volumes, savings become even more dramatic. If you're sending millions of emails, Sendy's economics are compelling.

Mailchimp's Feature Advantage

Mailchimp offers visual automation builders, advanced segmentation, landing pages, 300+ integrations, modern templates, and comprehensive analytics. Sendy offers basic campaigns, simple autoresponders, and dated interfaces. For anything beyond newsletters and simple sequences, Mailchimp is far more capable.

Technical Requirements Matter

Sendy requires server administration skills. You need to provision a web server, set up PHP/MySQL, configure Amazon SES (including getting production access), set up DNS records, and handle ongoing maintenance and updates. Mailchimp is sign-up-and-start with automatic updates and support.

For SaaS Companies

Neither platform is ideal for SaaS. Sendy lacks the automation and event tracking modern SaaS needs. Mailchimp lacks native Stripe integration and SaaS-specific features. For subscription businesses wanting Stripe integration and event-based automation, consider Sequenzy.

Making the Choice

Choose Sendy if you're technical, sending high volumes, have basic email needs, and want to minimize costs. Choose Mailchimp if you want modern features, polished UX, advanced automation, and don't want to manage servers. For SaaS companies, consider Sequenzy.

The Great Email Marketing Divide

Sendy and Mailchimp represent the widest possible gap in email marketing approaches. Mailchimp is the industry's most recognized brand with two decades of feature development, $12 billion acquisition by Intuit, and a platform that tries to be everything for everyone. Sendy is a $69 PHP application maintained by a small team. The comparison seems absurd until you look at the economics.

At 100,000 emails per month, Mailchimp charges $350+ depending on your plan and contact count. Sendy charges roughly $10 in Amazon SES fees. That is $4,000+ per year in savings. For businesses sending millions of emails, the savings can exceed $40,000 annually. These are not theoretical numbers -- they represent real budget that could fund other marketing activities.

The question every business must answer: are Mailchimp's features worth $4,000+ per year for your specific use case? For many businesses, the honest answer is no. They use Mailchimp for sending newsletters and basic automations, paying premium prices for features they never touch. For these businesses, Sendy delivers the core functionality at a fraction of the cost.

Feature Comparison: What You Actually Use

Mailchimp's feature list is impressive: visual automation, 300+ integrations, landing pages, social posting, CRM, content studio, predictive analytics, and more. But most users engage with a small subset of these features. Studies consistently show that email marketers primarily use: campaign creation, list management, basic automation, and reporting.

Sendy covers three of these four adequately. Campaign creation is basic but functional. List management handles subscriber imports, segmentation by list, and unsubscribe processing. Reporting includes opens, clicks, and bounces. Automation is where Sendy falls short -- basic autoresponders versus Mailchimp's visual workflow builder.

For businesses that need only campaigns and list management, Sendy provides 80% of the value at 3% of the cost. For businesses that rely on Mailchimp's automation, integrations, or landing pages, the value proposition shifts. The key is honest self-assessment: which features do you actually use, and which do you pay for but never touch?

The Integration Ecosystem Advantage

Mailchimp's 300+ integrations connect with virtually every business tool: Shopify, WordPress, Salesforce, Zapier, social platforms, CRM systems, and more. This ecosystem makes Mailchimp a hub for marketing data, connecting email engagement with other business systems. Sendy has minimal integrations -- essentially limited to Amazon SES and basic webhook support.

For e-commerce businesses, Mailchimp's Shopify integration enables abandoned cart emails, product recommendations, and purchase-triggered automation. These revenue-generating workflows require deep data integration that Sendy cannot provide. The integration is not a nice-to-have -- it directly drives revenue that justifies Mailchimp's pricing.

For content businesses that only need email delivery, integrations add no value. A newsletter sender does not need Shopify integration or social posting. They need reliable delivery at reasonable cost. Understanding whether integrations create value for your specific business model is essential to making the right platform choice.

Migration Economics and Lock-in Reality

Moving from Mailchimp to Sendy means exporting subscribers (easy), recreating templates (tedious), and losing automations (painful). Complex Mailchimp automations built over months cannot transfer to Sendy's basic autoresponders. The migration cost includes not just the move itself but the loss of accumulated automation logic.

Moving from Sendy to Mailchimp is straightforward: import subscribers, build templates in a better builder, and create automations from scratch. The asymmetry means starting with Sendy has lower switching costs than starting with Mailchimp. If there is any chance you will need advanced features, this migration path flexibility is worth considering.

For SaaS companies evaluating either platform, both lack native Stripe integration for subscription-based businesses. Sequenzy offers payment-triggered automation, transactional email, and revenue attribution at $49/month -- avoiding the Mailchimp vs Sendy dilemma entirely for software companies.
