v0.3.4

Migrate pyproject.toml package metadata from the legacy [tool.poetry] table to the PEP 621 [project] table. No functional or API changes — the package installs and behaves identically. Passes poetry check --strict.

v0.3.3

Add PEP 561 py.typed marker so type checkers in downstream projects pick up the package's inline annotations. Syncs Python 3.13/3.14 and Typing :: Typed trove classifiers to match CI.

v0.3.0

What's New

Synchronous Client (new in v0.3.0)

SyncServerClient and SyncAccountClient are now available via postmark.sync. Use them in scripts, Flask apps, and Jupyter notebooks — no async/await required. A single background thread with a persistent event loop handles all calls; HTTP connection pooling is retained for performance.

import postmark

with postmark.sync.ServerClient(token) as client:
    response = client.outbound.send({...})

Other Changes

• Examples reorganized into examples/async/ and examples/sync/ with parallel coverage
• New examples: send_sync_simple.py, send_sync_batch.py
• 31 new tests for sync client behavior (tests/test_sync_client.py)

Full Changelog: v0.2.5...v0.3.0

Full Changelog: v0.2.4...v0.2.5

v0.2.4

This is a patch release with one fix for the PyPI project page.

Fixed
The Postmark Python SDK logo was broken on the PyPI project page due to a relative image path in the README. It now uses an absolute URL and renders correctly.

Full changelog: 0.2.3 → 0.2.4

v0.2.0

[0.2.0] - 2026-03-06

Added

• User-Agent header sent on every request in the format Postmark.PY - {version} (Python/{major}.{minor}.{micro}).
• X-Request-Id from Postmark responses is now stored as request_id on all PostmarkAPIException subclasses and included in the exception __str__ output when present — enabling direct support escalations.
• request_id included in structured log records for both successful requests and API errors.
• Structured extra={} fields on all log calls (method, endpoint, status_code, duration_ms, error_code, postmark_message, request_id) for compatibility with Datadog, Splunk, and other log aggregators.
• duration_ms timing on every request log record (success, error, and timeout).

Changed

• Upgraded pytest-asyncio to ^1.0.0 and set asyncio_mode = "auto" to eliminate deprecation warnings on Python 3.12+.
