Upgrade To v2

This guide covers upgrading from the latest released v1 Python SDK to v2.

Highlights

Sending email now lives behind Lettermint.email(token).
The full Lettermint API is available through Lettermint.api(token).
Sending tokens use x-lettermint-token; full API tokens use Authorization: Bearer.
ping() returns the raw trimmed pong response.
Request and response shapes are generated from the OpenAPI specs as TypedDict/Literal types.

from lettermint import Lettermint

email = Lettermint.email("sending-token")
api = Lettermint.api("api-token")

Existing Lettermint(api_token="...").email sending usage still works.

email.send_batch([
    {"from": "sender@example.com", "to": ["user@example.com"], "subject": "Hello", "text": "Hi"}
])

domains = api.domains.list()
message_html = api.messages.html("message-id")
