VisitEmailEngine vs MailFrame
What both publish
| Fact | EmailEngine | MailFrame |
|---|---|---|
| Compliance | EmailEngine does not come with SOC 2 or ISO 27001 certification; its compliance posture depends on the environment where it is deployed. | SOC 2 Type II is on the roadmap, and MailFrame says it is not yet HIPAA-eligible as a Business Associate. |
| Data handling | EmailEngine runs on the customer’s infrastructure, caches sync metadata in the customer’s Redis, and fetches message bodies on demand rather than storing them. | MailFrame says it retains raw email content for the minimum time needed to deliver the response and surface debugging, and does not sell or share customer data. |
| Product | EmailEngine is a self-hosted email API that connects existing Gmail, Microsoft 365 and IMAP mailboxes through a unified REST API. | MailFrame is a developer-first API that turns raw email into typed, schema-validated JSON. |
| Support | The maker says support goes directly to the developer who wrote the code, and its annual subscription includes developer support. | Support varies by plan from community support on Free to email support on Indie and priority support on Startup. |

Pick MailFrame if…
MailFrame is aimed at app developers integrating inbound document email into their own services. It is relevant when the desired input is raw MIME or plain text and downstream systems can accept webhooks.
