Substack vs Mailchimp
Substack and Mailchimp both send email, but they're different categories of tool. Substack is a publishing platform built around paid newsletters and subscriptions, while Mailchimp is a broader email-marketing platform with automations, forms and landing pages. Which one fits depends on whether you want to charge readers or run campaigns.
Quick answer
Substack and Mailchimp solve different problems: Substack is the fastest way to launch a paid newsletter (it keeps 10% of subscription revenue), while Mailchimp is a broader email-marketing platform with automations and forms but no built-in paid-subscription model. Choose Substack to charge readers, Mailchimp to run campaigns. For selling products, bookings and tickets from one link while keeping 100% of sales, OneSol is a free all-in-one alternative that pays out to your own Stripe.

1. Who Substack is best for
Substack suits writers and creators who want to launch a newsletter fast and charge readers for paid subscriptions with almost no setup. It's free to publish and only costs you when you earn — Substack keeps 10% of paid subscription revenue on top of Stripe's fees. There's little in the way of automation or segmentation, so it's built for publishing, not campaigns.
2. Who Mailchimp is best for
Mailchimp fits small businesses and marketers who need automations, segmentation, landing pages and signup forms rather than a paid-content model. Its free plan works for small lists but caps contacts and monthly sends, with features scaling into paid tiers as you grow. It doesn't take a cut of sales, but it also isn't built to sell paid subscriptions the way Substack is.
3. The cost that's easy to miss
With Substack the 10% platform cut is invisible until money comes in, and it applies for as long as a subscriber keeps paying. With Mailchimp the free plan feels generous until send limits and contact caps push you onto paid tiers. Neither is a full storefront, so selling products, tickets or bookings means bolting on other tools.
The verdict
OneSol pulls selling, forms, bookings, tickets and email capture behind a single link, so you don't need to run a newsletter tool and a marketing tool side by side. Payments go straight to your own Stripe account and OneSol takes no cut, so you keep 100% of every sale. It's free to start — no card, no code.
