When Mailchimp wins
- Small businesses that want one tool with a real onboarding flow and a huge integration list
- Teams already living in Intuit (QuickBooks) products
- Operators who want a brand-name vendor for stakeholder approval
Where Mailchimp is the wrong fit
- Creators with growing newsletters; the per-contact tax compounds (Kit, beehiiv, or MailerLite tend to be cheaper at 10k+ subscribers)
- B2B sales teams; the CRM is light versus HubSpot or ActiveCampaign
- Teams needing predictive AI on a budget; you have to jump to the $350 Premium plan
When PostHog wins
- Technical product teams that want one tool covering analytics, experiments, replay, and surveys
- Startups under 1M events per month, where the free tier covers the entire stack
- Companies committed to open-source infrastructure who want the option to self-host
Where PostHog is the wrong fit
- Marketing-only teams who need attribution and campaign analytics (Mixpanel or GA4 fit better)
- Enterprises with strict procurement that requires a SaaS-only vendor with no self-hosted option in scope
- Non-technical users who cannot navigate event-based analytics UIs and SQL-style insights
