You can find the original at [wildbit/postmark-php](https://github.com/wildbit/postmark-php) This library preserves the api of the original, but has been updated to work on PHP 8.0 and 8.1 with improved type safety, internal re-organisation and BC breaking changes such as renamed/refined exception types, return type hints and parameter type hints. You can find a summary of the differences in the pull-request on the original lib: [\#94](https://github.com/wildbit/postmark-php/pull/94) This version of the lib **does not ship** an HTTP client, or get one from composer… You'll need to install a PSR-18 compatible HTTP client up front such as [Guzzle](https://github.com/guzzle/guzzle), [php-http/curl-client](https://github.com/php-http/curl-client) etc. Versions -------- [](#versions) This package is marked as a replacement for `"wildbit/postmark-php": "4.0.2"` so it **will** break your project and any dependent libs if your types are out of whack. Hopefully [\#94](https://github.com/wildbit/postmark-php/pull/94) will get merged so none of this is necessary… ### Health Score 56 — FairBetter than 98% of packages Maintenance69 Regular maintenance activity Popularity27 Limited adoption so far Community18 Small or concentrated contributor base Maturity93 Battle-tested with a long release history Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
