Fix Your AI-Built SendGrid Integration
Email delivery service by Twilio for transactional and marketing email. AI tools use deprecated API patterns and miss critical sender authentication setup.
Common SendGrid issues we find
Problems specific to AI-generated SendGrid integrations.
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.
No unsubscribe handling in transactional emails
Generated code sends transactional emails without proper unsubscribe headers or links, violating CAN-SPAM and risking account suspension.
Template rendering errors not caught
AI tools use dynamic templates without validating that all required template variables are provided, causing emails to send with empty or broken content.

Frequently asked questions
Why are my SendGrid emails being rejected or landing in spam?
AI-generated setups skip sender authentication (domain verification with SPF and DKIM records). Without these, receiving servers flag your emails as potentially spoofed. We configure complete sender authentication and verify deliverability.
Is my AI-generated SendGrid API key too permissive?
Almost certainly. AI tools use full-access API keys for convenience. A proper setup uses restricted keys with only the permissions your app needs (typically just Mail Send). We audit your key permissions and create properly scoped replacements.
How do I handle bounces and unsubscribes with SendGrid?
AI tools ignore bounce and complaint handling entirely. You need Event Webhook integration to process bounces, spam complaints, and unsubscribes in real time, then suppress those addresses from future sends. We set up the full feedback loop.
