If you are a freelance writer building an email list, you have a real choice to make: go with Mailchimp, the established email marketing platform used by millions, or Substack, the newsletter-first platform that has taken the writing world by storm?

The answer depends on what you want: Substack is built for newsletter monetization and direct reader relationships. Mailchimp is built for email marketing, campaigns, and list management at scale. They serve different purposes, and picking the wrong one can cost you months of wasted effort.

Here is the honest 2026 comparison for freelance writers.

Quick Comparison

Mailchimp — The Email Marketing Workhorse

Mailchimp is one of the largest email marketing platforms in the world, serving over 13 million users. It was built for businesses and marketers who need sophisticated email campaigns, automation, landing pages, and CRM features. For freelance writers, it is most useful if you plan to use email as a marketing channel — driving traffic to your blog, promoting services, or running campaigns.

What makes it great for writers:

• Proven deliverability — Mailchimp has some of the best email deliverability rates in the industry. Your newsletters actually reach inbox, not spam.
• Advanced automation — Set up welcome sequences, drip campaigns, and automated follow-ups without technical knowledge.
• Landing pages and signup forms — Create dedicated landing pages to grow your list, with A/B testing on subject lines and content.
• Segmentation — Divide your list by subscriber behavior, interests, or engagement level to send more targeted content.
• Analytics — Open rates, click rates, unsubscribe rates, and geographic data — comprehensive enough for serious list building.

The tradeoff: Mailchimp is not designed for newsletter publishing. The reading experience in emails is functional but not optimized for long-form writing. There is no native "publication" feel — your newsletter looks like a marketing email.

Substack — Built for Writers Who Want to Monetize

Substack was built specifically for writers who want to publish newsletters and potentially earn money from them. It combines email list management, a web publication, and payment processing in one place. The entire product is designed around the idea that writers should own their relationship with readers and be able to charge for premium content.

What makes it great for writers:

• Native monetization — Set up paid subscriptions in minutes. Substack takes 10% of subscription revenue (reduced to 9% with their affiliate program). No third-party payment integration needed.
• Reader-facing publication — Your newsletter also gets a beautiful web version. Readers who do not check email can read on the web — expanding your reach.
• Writer discovery — Substack has a built-in directory and recommendations system. New writers can gain subscribers through Substack's own network, something no other platform offers.
• Tip jar and gifts — Readers can tip you for individual posts or gift subscriptions to others — additional revenue streams beyond subscriptions.
• Simplicity — No confusing dashboards or settings. Write, publish, send. It just works.

The tradeoff: Substack's email marketing features (segmentation, automation, A/B testing) are more limited than Mailchimp. If you want to run sophisticated email campaigns or use your list for multiple purposes, Substack can feel constrained.

Feature-by-Feature Breakdown

Getting Started

Substack wins on simplicity. Creating a newsletter takes 5 minutes — pick a name, write your first post, set up Stripe, and you are live. Mailchimp requires more setup: creating audiences, configuring signup forms, setting up automations. The tradeoff: Mailchimp gives you more control, but Substack gets you publishing faster.

Writing and Publishing Experience

Substack is purpose-built for writers. The editor is clean, the web publication looks professional, and the email rendering is excellent. You write in Substack's editor and the output looks great in both email and web formats.

Mailchimp's campaign editor works fine but feels like a marketing tool. Long-form newsletter content is not its primary use case — the templates are designed for promotional emails with short copy blocks.

Audience Growth

Mailchimp is the stronger tool for audience growth. Its landing page builder, signup forms, A/B testing, and automation features are all designed to systematically grow and engage your list.

Substack's growth features are improving but still behind. The built-in directory and recommendations are valuable for discovery, but Substack writers often rely heavily on Twitter/X and cross-promotion with other Substack writers to grow their lists.

Monetization

Substack wins decisively. Paid subscriptions, tip jar, gift subscriptions — all built in. You can be earning money from your newsletter within a week of starting.

Mailchimp has no native monetization features. To monetize a Mailchimp list, you need to drive readers to an external product, course, or service. This makes Mailchimp better as a marketing tool for your freelance writing business, not a direct revenue source from the newsletter itself.

Pricing and Value

Mailchimp free plan covers 500 contacts and 1,000 emails/month — fine for small lists. Paid plans start at $13/month for up to 500 contacts, scaling up based on list size. As your list grows, Mailchimp gets expensive fast.

Substack is free for up to 3 paid posts per month. The paid plan charges 9% of subscription revenue — so Substack only makes money when you make money. For writers building a revenue newsletter, this alignment of incentives is refreshing.

Which Should Freelance Writers Choose?

Choose Mailchimp if:

• You are using email as a marketing channel for your freelance services or blog
• You want advanced automation, segmentation, and A/B testing
• You already have a large list or plan to grow one substantially
• You are comfortable with more complex setup in exchange for more powerful features
• Email deliverability is your top priority

Choose Substack if:

• You want to publish a newsletter and potentially monetize it through subscriptions
• You value simplicity and want to start publishing quickly
• You are a new writer who wants built-in discovery and reader relationships
• You prefer a platform where the revenue model is aligned with writer success
• You want both email and web publication without extra setup

The Bottom Line

For most freelance writers building a newsletter in 2026, Substack is the better starting point. The writer-first design, native monetization, and built-in discovery make it the best platform for writers who want to build an audience and potentially earn from their writing. The simplicity means you spend less time managing the tool and more time writing.

Mailchimp remains the superior choice for writers who treat email as a marketing channel — driving traffic to their blog, promoting freelance services, or running product campaigns. If that is your strategy, Mailchimp's advanced features justify the extra complexity.

The good news: both platforms offer free plans. Start on both, publish a few newsletters, and see which feels right for your writing style and goals. Using affiliate links above supports this blog at no extra cost to you.
