Adding SendGrid to your Claude Code app? Let us review it.
Expert review for SendGrid integrations built with Claude Code. We fix Claude Code-generated SendGrid code for security, error handling & production readiness. From $19.
Common Claude Code issues affecting integrations
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
SendGrid issues we find in Claude Code apps
Using deprecated v2 Mail Send API
AI tools generate code using the SendGrid v2 API endpoint and format instead of the current v3 Mail Send API, missing features and facing eventual deprecation.
Sender authentication not configured
Generated code sends from addresses without domain authentication (SPF/DKIM), causing emails to fail or be marked as spam by receiving mail servers.
API key has full access instead of restricted permissions
AI tools create and use API keys with full admin access when only Mail Send permission is needed, creating an unnecessary security risk if the key leaks.

Frequently asked questions
Can you review my Claude Code-built SendGrid integration?
Yes. We regularly audit SendGrid integrations in Claude Code-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What SendGrid issues does Claude Code typically create?
Common issues in Claude Code-generated SendGrid code include: using deprecated v2 mail send api, sender authentication not configured, api key has full access instead of restricted permissions. We fix all of these in our code review.
How much does it cost to fix my SendGrid integration?
Start with our code audit ($19) to get a complete list of SendGrid issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What SendGrid best practices does Claude Code typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for SendGrid. Our review checks all of these and provides specific fixes.
