Transactional Emails Delayed by Minutes or Hours
Password reset emails, verification links, and order confirmations from your application arrive minutes or even hours after the user requested them. By the time the email arrives, verification tokens have expired, users have given up, and time-sensitive notifications are useless.
Email delays are especially damaging for authentication flows. A password reset email that arrives 30 minutes late means the user can't log in for 30 minutes. A verification email that arrives after the token expires means the user has to start over, if they haven't already abandoned your app.
The delay may be inconsistent, with some emails arriving in seconds and others taking hours, making the problem hard to diagnose and reproduce.
Error Messages You Might See
Password reset link has expired
Verification token expired, please request a new one
Email delivery webhook: delayed
Rate limit exceeded, emails queued
Common Causes
- Emails sent synchronously in request handler — The email API call blocks the HTTP response, and the email service queues it with low priority
- No dedicated IP or sender reputation — Using shared sending infrastructure that throttles delivery based on volume
- Missing SPF/DKIM/DMARC records — Receiving servers delay or reject emails from domains without proper authentication records
- Rate limiting by provider — Free tier or low-volume plans have sending rate limits that queue excess emails
- Background job queue backed up — If using a job queue for emails, other long-running jobs are blocking email delivery
How to Fix It
- Send emails asynchronously — Use a background job queue (Bull, Celery, Sidekiq) to send emails without blocking the request
- Prioritize transactional emails — Use a separate queue or higher priority for password resets and verifications vs marketing emails
- Configure DNS authentication — Set up SPF, DKIM, and DMARC records for your sending domain to improve deliverability
- Use a dedicated sending domain — Don't send from a free email provider domain. Use your own domain with proper authentication
- Monitor delivery latency — Track the time between email send request and actual delivery using provider webhooks

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.**

I enjoy solving complex engineering problems and designing systems that are maintainable, resilient, and built to scale.
David Olverson
Solo dev shipping production apps with AI-assisted development. I specialize in rescuing broken Lovable/Bolt/Cursor builds and taking them to production. 10+ apps shipped including SaaS CRMs, gaming platforms, real estate tools, and Discord bots. Stack: Next.js 16, TypeScript, Tailwind CSS, FastAPI, PostgreSQL, Prisma. I use Claude Code with 50+ custom skills for rapid delivery. Average turnaround: 2-4 weeks from broken prototype to production.

I build and fix web apps across Next.js, Node.js, and DBs.
Comfortable jumping into messy code, broken APIs, and mysterious bugs.
If your project works in theory but not in reality, I help close that gap.
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.

Get HelpFrequently Asked Questions
Why do some emails arrive fast but others are delayed?
Inconsistent timing usually points to rate limiting or shared infrastructure. When many customers send at the same time, emails queue up. Upgrading to a dedicated IP or higher-tier plan typically resolves this.
How do I set up SPF and DKIM?
Add DNS TXT records provided by your email service. SPF specifies which servers can send email for your domain. DKIM adds a cryptographic signature. Both are required for reliable delivery.
