1. Mailchimp - best all-rounder for small business

Mailchimp is the most recognized email tool for a reason: a friendly editor, polished templates, and a gentle learning curve make it the natural choice for newsletters and small-business campaigns. Note that its free plan dropped to 250 contacts and 500 monthly sends in 2026, and pricing counts subscribed, unsubscribed, and non-subscribed contacts toward your limit, so model the cost at your real list size.

Best for: Small businesses and creators who value ease of use.

  • Strengths: Easy editor; great templates; broad integrations; AI assists.
  • Limitations: Automation is shallow next to dedicated tools; contact-based pricing climbs.
  • Pricing: Free (250 contacts), Essentials from $13/mo, Standard $20/mo, Premium $350/mo.

2. Brevo - best value

  • Strengths: Email-volume pricing; unlimited contacts; SMS and CRM included.

How to choose email marketing software

Start with your use case. For simple newsletters, Mailchimp or Brevo are easiest, and Brevo wins on value if your list is large but lightly emailed. For ecommerce, Klaviyo’s behavioral data is hard to beat. If automation is central, ActiveCampaign offers the most depth for the money, while HubSpot makes sense when you want email unified with a CRM. Finally, model pricing at your real list size: contact-based tools (Mailchimp, Klaviyo) climb as you grow, while Brevo’s email-volume model can be cheaper for big lists.
