Walkthrough

README.md was restructured and expanded: the "Supported functionality" block was replaced with a "Framework integration" section for Symfony and Laravel, and the Usage section was extended with minimal transactional examples, sandbox vs production guidance, bulk streaming, and a full-featured email construction example. CHANGELOG.md adds a new 3.9.1 entry noting README improvements.

Poem

🐇 I hopped through lines of README bright,

Guides and examples set just right,
Sandbox, bulk, and templates sing,
Bridges to frameworks now take wing,
A tiny hop — docs gleam with light. ✨

Pre-merge checks and finishing touches

❌ Failed checks (2 warnings, 1 inconclusive)

Check name	Status	Explanation	Resolution
Description Check	⚠️ Warning	The pull request description "Improve README file" is extremely minimal and does not follow the required template structure. The template specifies required sections including Motivation, Changes (with bullet points), How to test (with checkboxes), and an optional Images and GIFs section. The provided description contains none of these sections—no motivation is explained, no detailed list of changes is provided, and no testing guidance is included. This represents a largely incomplete description that fails to meet the repository's documentation standards.	Please expand the pull request description to follow the template by adding: a Motivation section explaining why the README improvements were needed, a Changes section listing the specific updates (such as adding framework integration section, expanding usage examples, and reformatting supported functionality), and a How to test section with verification steps. The raw summary provides useful details that should be incorporated into the description.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	You can run @coderabbitai generate docstrings to improve docstring coverage.
Title Check	❓ Inconclusive	The title "Improve README" is directly related to the changeset, as the raw summary confirms the README.md was substantially updated with new sections, examples, and restructured content. However, the title is quite generic and vague—it uses a non-descriptive term ("Improve") that could apply to almost any documentation change without conveying what specific improvements were made. A teammate scanning the history would understand that the README changed, but not whether framework integrations were added, examples were expanded, or other specific enhancements occurred.

76-81: Specify language for environment variables code block.

Add a language identifier to the fenced code block for better rendering and syntax highlighting:

-Example `.env` variables (or export in shell):
-```
+Example `.env` variables (or export in shell):
+```bash
 MAILTRAP_API_KEY=your_api_token # https://mailtrap.io/api-tokens

This addresses the MD040 linting hint and improves readability.

README.md (2)

33-39: Framework integration section improves discoverability.

The new section clearly signposts bridge packages and reduces friction for framework users—good addition to the documentation.

---

44-229: Usage examples are well-structured and progressively informative.

The progression from minimal to full-featured examples with clear sandbox/production guidance and exception handling provides excellent documentation for different user levels.
