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
When Resend wins
- Developers shipping a transactional flow such as signup confirmations, password resets, and receipts
- Teams using React for email templates
- Startups wanting a clean modern API without legacy ESP weight
Where Resend is the wrong fit
- Marketing teams running newsletters (use Kit or beehiiv)
- Enterprises with strict legacy integration requirements
- Teams that need deep dedicated-IP warmup tooling (Mailgun and SendGrid are more mature here)
