What Is Mailchimp?
Mailchimp is a web-based email marketing platform with iOS and Android apps. Its drag-and-drop Email Builder, template library, Content Studio for creative assets and generative AI copy tools cover campaign creation, while A/B testing, multivariate testing on higher plans and Send Time Optimization guide when and what to send. Audience data lives in a marketing CRM with tags, customer profiles, behavioral targeting, predictive segmentation, surveys, and sign-up and popup forms. Marketing Automation Flows build triggered sequences, and landing pages, SMS and MMS add-ons and retargeting ads extend campaigns beyond the inbox. Mailchimp Transactional, an add-on for order confirmations and password resets, sends through an API or SMTP and is available on Standard and Premium. Plans are Free, Essentials, Standard and Premium, with limits tied to contact count, seats, audiences and monthly sends. Mailchimp lists more than 300 integrations, including Shopify, WordPress, Canva, Salesforce and Meta.
Best for: Small and growing businesses that want newsletters, automated sequences and audience segmentation from one email-first platform.
Mailchimp separates its core marketing product from Mailchimp Transactional, so application-generated receipts or password emails require a distinct transactional service and compatible paid marketing plan. For marketing campaigns, the Customer Journey Builder, audience segmentation, templates, and testing tools provide a broader workflow than a developer-only email API.
