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
Email sending failed - invalid API key
Sender address not verified
Invalid email address
Email bounced - address unreachable
Email marked as spam
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

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

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.**

Matthew Jordan
I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
How do I verify sender?
In email service dashboard, verify sender email. Click confirmation link or add DNS records
What's DKIM/SPF/DMARC?
DNS records proving you own the domain. Prevents spoofing and improves delivery. Add in domain DNS settings
Why are emails going to spam?
No DKIM/SPF, OR content has spam triggers. Use templates, verify sender, add unsubscribe link
