- Revenue teams using HubSpot or Salesforce that need lead routing and round-robin
- Customer success teams running round-robin assignments across pods

- Operations needing complex scheduling logic only available on Enterprise
When Mailtrap wins
- Dev teams that want one vendor for both email testing and production sending

- Buyers who want flat predictable per-tier pricing (Postmark is more predictable)
- Enterprises needing voice or SMS in the same platform (use Twilio or SendGrid)
