When Kit wins
- Independent newsletter writers and creators selling digital products
- Course creators who want one tool for emails and checkout
- Solo operators with under 10k subscribers (free plan covers them)
Where Kit is the wrong fit

- Brands that need deep multi-channel marketing automation (use ActiveCampaign or HubSpot)
- Teams that need granular role-based permissions
When Postmark wins

- Teams that need detailed inbound email parsing alongside outbound sends
- Companies that need 365-day data retention for compliance
Where Postmark is the wrong fit

- Marketing teams (use Mailchimp or Kit)
- Buyers who want a single vendor for marketing and transactional email
