Instantly Send Email

Send email through Instantly's real workflow paths.

Core Model

Instantly API V2 does not expose a generic direct POST /send endpoint for new outbound email.

Use these workflows:

Cold/outbound first touch: find or create a Lead, let the user choose or create a Campaign, then place the Lead into that Campaign. Instantly sends according to the campaign's configured sequence, sender accounts, schedule, limits, and health.
Reply to an existing conversation: list emails for the lead email address, let the user choose the specific email, then call POST /api/v2/emails/reply with that selected email's id as reply_to_uuid.

Never use POST /api/v2/emails/test for user-requested sending. It is only a preview/test endpoint.

Use exactly these bundled scripts:
