Email list hygiene is free until it isn't. Mailchimp scales from 500 free contacts to enterprise, with automation that doesn't require a developer.
Mailchimp is the default email marketing platform for founders who need to move a spreadsheet into a system. It's not the most powerful tool in the category, but it's the one most operators already have a login for. The free tier lets you manage up to 500 contacts and send unlimited campaigns. That's real. You get drag-and-drop templates, basic segmentation, and automation workflows—enough to run a welcome series or post-purchase sequence without touching code. The interface is built for non-technical users, which means it's also built for speed over flexibility. Who uses it: Early-stage SaaS founders managing their own email, e-commerce operators running abandoned cart flows, agencies building client email infrastructure on a budget. If you're pre-PMF and your email list is under 5,000 contacts, Mailchimp is the path of least resistance. The operator workflow looks like this: import your list (or connect Shopify/WooCommerce), segment by behavior or custom fields, build a campaign or automation sequence using templates, set it live, then check open rates and click-through data in the dashboard. No Zapier required for basic flows. If you need to trigger an email on a specific user action, Mailchimp's automation builder handles it—but the trigger library is smaller than Klaviyo's or HubSpot's. Pricing scales predictably. Free tier caps at 500 contacts. Paid plans start low and climb with list size, not feature count. The catch: advanced segmentation, dynamic content, and predictive send time live behind higher tiers. If you're running sophisticated behavioral workflows or need deep integrations with your product database, you'll hit Mailchimp's ceiling and start looking at Klaviyo or HubSpot. Common failure mode: operators import a messy list, don't clean it, then get flagged for high bounce rates. Mailchimp's deliverability is solid, but garbage in = spam folder out. The platform also doesn't auto-sync list churn—you need to manually remove unsubscribes or set up a two-way integration. Alternatives: Klaviyo if you're e-commerce and need advanced segmentation and SMS. ConvertKit if you're a creator. HubSpot if you want email bundled with CRM and sales tools. Brevo (formerly Sendinblue) if you need SMS and email together at lower cost. Mailchimp's real strength is that it's boring and it works. No surprises, no feature creep, no vendor lock-in drama. You can export your list anytime. That's worth something.
