MailerLite

MailerLite gives small businesses the best balance of generous free plan, clean automation builder, digital product selling, and honest pricing that stays affordable as you grow — without Mailchimp's pricing traps or ActiveCampaign's complexity.

What it does well
  • Free plan includes 500 subscribers and 12,000 emails/mo — enough to run real campaigns
  • Automation workflows are intuitive with time-delays, conditions, and action splits
  • Digital product selling (ebooks, courses, paid newsletters) built into all paid plans with no transaction fees
Watch out for
  • No built-in CRM — contact management is email-list-centric, not a full sales pipeline
  • Template library is smaller than Mailchimp's, though the email editor is flexible

Mailchimp

Mailchimp is the most recognizable email platform globally, with a drag-and-drop editor, audience tools, and a free tier — though its free plan's 500-contact and 1,000 email limits are restrictive for active senders.

What it does well
  • The most widely recognized email brand — easy to get buy-in from team members and clients
  • Extensive integration library covering most CRMs, e-commerce platforms, and business tools
  • Solid landing page builder on all plans including free
Watch out for
  • Free tier limits are tight: 500 contacts and 1,000 emails/mo — too restrictive for active list-building
  • Pricing on paid tiers is significantly higher than MailerLite for the same contact count
Best For Small businesses that prioritize brand familiarity, need integrations with a specific tool that only connects to Mailchimp, or are just experimenting with email for the first time.

ActiveCampaign

ActiveCampaign is a full marketing automation platform with a visual workflow builder, CRM pipeline, and lead scoring — more powerful than either alternative, but also more expensive and complex.

What it does well
  • The most powerful automation builder in email marketing — handles any multi-step conditional sequence
  • Built-in CRM with deal stages so email engagement automatically updates your sales pipeline
  • Predictive sending chooses the optimal time to deliver to each contact based on their history
Watch out for
  • No free tier — 14-day trial only; starts at $15/mo for 1,000 contacts
  • Overkill for businesses that just need newsletters and basic automations
Best For Small businesses with a complex sales process, high-ticket offers, or B2B clients that need automation logic beyond simple welcome sequences.

Frequently Asked Questions

What's the best free email marketing tool for small businesses? +

MailerLite — its free plan covers 500 subscribers and 12,000 emails per month, includes automations and landing pages, and doesn't require a credit card. Mailchimp's free tier only allows 1,000 emails per month total, which limits your sending frequency as soon as your list grows.

How many emails per month does a small business typically need to send? +

A list of 1,000 subscribers sending one email per week uses about 4,000–5,000 sends per month. MailerLite's free plan (12,000/mo) handles that comfortably. Mailchimp's free plan (1,000/mo) does not — you'd hit the limit with just one send to a 1,000-person list.

Do I need an automation platform or is a basic email tool enough? +

For most small businesses, a welcome sequence + occasional promotional email is all you need initially — MailerLite covers that on its free plan. Upgrade to ActiveCampaign when email is a primary revenue driver and you need conditional logic that responds to contact behavior across your full funnel.
