Email Sending Fails - Emails Never Received
Emails aren't being sent. Email API returns success but users never receive the emails. Emails sent but marked as spam.
No error logs showing what went wrong.
Error Messages You Might See
Common Causes
- Email service API key incorrect or not loaded
- Sender email not verified with service
- Email address invalid or bouncing
- Missing DKIM/SPF/DMARC records causing spam filters
- Email content flagged as spam
How to Fix It
Check API response: email services return delivery errors
Verify sender email: must be verified in email service (SendGrid, Mailgun, etc.)
Check spam folder: legitimate emails might land there
Configure email records: DKIM, SPF, DMARC in DNS for higher delivery
Test email: send to own mailbox first, check content for spam triggers (ALL CAPS, many links)
Use verified templates: pre-written email templates have better delivery

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**
