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 also mentor junior developers and contribute to technical decisions and code reviews.
Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

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
