For a startup or solopreneur:
Total cost: $0/month. This is a legitimate, functional marketing stack.
Upgrade when:
Yes. A complete campaign — blog post + social posts + email newsletter + landing page — is achievable with: Assisters (free credits) for writing, Canva free for graphics, Buffer free for social scheduling, and MailerLite free for email. This covers the full campaign at $0 cost.
Yes, for most tasks. ChatGPT's free tier (GPT-4o mini) is good enough for writing social captions, drafting email copy, brainstorming campaign ideas, and generating content outlines. For longer-form articles and complex analysis, GPT-4o (paid) or Claude is better.
Canva AI (free) for creating visuals and Buffer (free — 3 channels) for scheduling. For AI-generated captions, use ChatGPT free tier or Assisters. This combination covers design, scheduling, and copy for social media at zero cost.
MailerLite has the most generous free tier: 1,000 subscribers, 12,000 emails/month, automation, and AI writing features. Beehiiv is better for newsletters specifically (up to 2,500 subscribers free). Brevo is better if you need SMS in addition to email.
Free tiers have usage limits but are generally reliable from established providers (Google, Canva, MailerLite, Buffer). The risk is hitting a limit at a critical moment. Always know your usage limits and plan upgrades before you hit them.
A complete, functional AI marketing stack is available for $0 in 2026. Start with Assisters (10 free AI generations) + Canva free + MailerLite free + Buffer free, then upgrade channels individually as your business grows.
