Primitive

Inbound email infrastructure for AI agents — receive emails on a custom domain and get structured webhook payloads with parsed content, attachments, and authentication results (SPF/DKIM/DMARC). Best for agent workflows that need to process incoming emails programmatically. Unlike outbound email services (SendGrid, Mailgun), Primitive handles the receiving side with webhook delivery and automatic retries. 1 example endpoint available through Lava’s AI Gateway. See the Primitive API docs for full documentation.

This provider requires your own credentials — connect your API key or OAuth account before use.

This is a catch-all provider — any valid URL under https://api.primitive.dev is supported. Inbound email API. Construct URL as https://api.primitive.dev/{path}. The endpoints below are curated examples.
