Mailchimp adopts a tiered pricing model that scales with the features and number of contacts. Their free plan is quite generous, accommodating up to 2,000 contacts and 10,000 sends per month, with a daily limit of 2,000. This makes it an ideal choice for small businesses and startups just beginning to build their email marketing initiatives. For more advanced features, Mailchimp offers three paid plans: Essentials, Standard, and Premium. The Essentials plan starts at around $10 per month, including access to all email templates, A/B testing, and a custom branded domain. The Standard plan, starting around $15 per month, introduces more sophisticated features like event-based automation, retargeting ads, and advanced audience insights.
