Brevo

Brevo (formerly Sendinblue) is an all-in-one marketing platform that combines email, SMS, landing pages, and CRM in one tool. The free tier is genuinely generous: 300 emails per day, unlimited contacts, basic automation, and SMS credits. For indie hackers managing tight budgets, this is a legitimate long-term free option—you can run real marketing campaigns without paying a cent.\n\nThe paid plans start at $9/month for email + SMS combined, making it one of the most affordable full-stack marketing solutions. What indie hackers love: SMS is included (not an expensive add-on), automation and segmentation work across email and SMS, and the interface is cleaner than Mailchimp's legacy dashboard. For multi-channel campaigns without breaking the budget, Brevo delivers impressive value. Perfect for ecommerce stores, SaaS onboarding, and newsletters targeting both email and SMS audiences.
