What is Mailchimp?
Mailchimp is one of the best-known email and SMS marketing platforms in the world — a tool that lets businesses build an audience, create campaigns, automate their marketing and measure the results, all without a steep learning curve. Part of the Intuit family, it's used by everyone from tiny startups to brands like Spotify and Canva.
What Mailchimp is
Mailchimp combines audience management, campaign creation, marketing automation and analytics in one platform. You collect and segment contacts, design emails (and SMS) with customizable templates, set up automated workflows that send the right message at the right time, and track how it all performs — with AI now helping generate content and predict which segments to target.
Who it's for
Mailchimp serves small businesses and startups, ecommerce retailers, professional-services firms, non-profits, restaurants and mid-market companies. Its ease of use makes it especially popular with smaller teams that need effective marketing without hiring specialists, while its depth still serves larger organizations.
What it offers
- Email campaign creation with customizable templates
- SMS marketing (add-on)
- Marketing automation workflows
- Audience segmentation and built-in CRM
- A/B and multivariate testing
- Generative AI for content and predictive segmentation
- Popup form builders and Canva integration
- 300+ integrations (Shopify, WooCommerce, Salesforce, WordPress, Zapier)
Marketing minus the learning curve
Mailchimp's enduring appeal is accessibility — it's built so a non-marketer can put together a professional campaign quickly. Customizable templates, a straightforward interface and Canva integration mean you don't need design skills, and the platform's own tagline, "marketing minus the learning curve," captures why it became the default for so many small businesses taking their first steps into email marketing.
Automation that does the timing for you
Beyond one-off sends, Mailchimp's automation is where a lot of its value lives. You can set up workflows — welcome series, abandoned-cart reminders, re-engagement campaigns — that trigger automatically based on customer behavior, so the right message goes out at the right moment without manual effort. Combined with segmentation and predictive AI, that lets even a small team run sophisticated, personalized marketing on autopilot.
Connected to your whole stack
Mailchimp isn't an island — it connects to 300+ apps across ecommerce (Shopify, WooCommerce, Square), CRM (Salesforce), design (Canva), web platforms (WordPress, Wix), social media and more. For an online store especially, that means purchase and customer data can flow into Mailchimp to power targeted, automated campaigns. Being developer-friendly with API access and webhooks, it also fits more custom setups.
Test, learn and improve
Mailchimp helps you get better over time rather than sending blindly. Built-in A/B and multivariate testing let you compare subject lines, content and send times to see what actually drives opens and clicks, while its analytics and reporting dashboards give clear insight into audience growth and conversion funnels. Predictive segmentation then uses that data to suggest which contacts to target. For a small team, that closed loop of testing and measuring means each campaign can outperform the last without needing a dedicated analyst.
Support when you need it
Mailchimp doesn't leave you entirely on your own as you scale. Higher tiers include dedicated support and personalized onboarding, and expert services — including data-migration assistance for moving from another platform — help teams get set up correctly. For a business making email marketing a serious channel, having real help available (rather than only documentation) lowers the risk of the whole effort stalling on a technical snag.
Why choose Mailchimp
For businesses that want approachable yet capable email and SMS marketing, Mailchimp is a proven, popular choice. Its easy campaign creation, powerful automation, segmentation and AI features, and huge integration ecosystem — backed by a free tier, a 4.5-star rating across tens of thousands of reviews, and Intuit's resources — make it a practical way to grow and engage an audience, whether you're sending your first newsletter or running mature, automated marketing.
What is Substack?
Substack is a publishing platform that makes it simple for writers and creators to start a newsletter, grow an audience, and earn money directly from their readers through paid subscriptions. It rose to prominence by championing a powerful idea: that independent writers should be able to own their relationship with their audience and make a living from their work, without depending on advertising or social media algorithms. With Substack, anyone can become a publisher in minutes and build a sustainable business around their writing.
The platform handles everything a writer needs: a clean place to write and publish posts, an email newsletter that delivers each piece straight to subscribers' inboxes, a website for the publication, and built-in tools to offer paid subscriptions and collect recurring revenue. Writers keep ownership of their content and their subscriber list, and Substack only earns when they do, taking a percentage of subscription revenue. Beyond text, it supports podcasts, video, community discussion threads, and recommendations between publications that help writers grow, making it a full home for independent media.
Substack is used by journalists, experts, novelists, and creators of every kind who want to build a direct, paid relationship with their audience. The value is independence and ownership: it lets writers turn their expertise and voice into a real income stream they control, free from the volatility of ad revenue and platform algorithms. For the many writers seeking a sustainable alternative to traditional media or social platforms, Substack offers an accessible, well-designed way to publish, build a loyal audience, and get paid for their work — which has made it a cornerstone of the modern creator economy and independent publishing.
