FAQ
What is the best free email marketing software?
Mailchimp (free up to 500 contacts, 1,000 sends/month) and Brevo (free up to 300 emails/day, unlimited contacts) are the strongest free tiers. For e-commerce, Klaviyo’s free plan (250 contacts) is more valuable despite the lower contact limit because of its Shopify integration.
How do I choose between Mailchimp and ActiveCampaign?
Mailchimp if you need simple newsletters and basic automation. ActiveCampaign if you need complex multi-step automation with conditional logic, CRM integration, and advanced segmentation. ActiveCampaign is harder to learn but significantly more powerful for sophisticated campaigns.
