Email Deliverability & DNS Configuration Having trouble with emails landing in spam, failing authentication checks, or not reaching their recipients? I help businesses diagnose email delivery issues and configure the DNS and mail infrastructure needed for reliable email communication.

With hands-on experience across shared hosting, VPS environments, SMTP configuration, and domain authentication, I can help identify misconfigurations and resolve common deliverability problems.

SPF, DKIM, and DMARC configuration and troubleshooting

DNS record setup and correction, including MX, A, and CNAME records

SMTP configuration, including ports, TLS, and authentication

Email sending issues involving shared hosting and VPS environments

Mail server hostname, HELO/EHLO, and reverse DNS (PTR) configuration

Cloudflare DNS configuration and propagation checks

Email authentication, alignment, and deliverability testing

Troubleshooting emails landing in spam or failing authentication

DNS and mail configuration following website or server migrations

I investigate the underlying configuration, check relevant DNS records and authentication results, and test the changes where possible. I focus on practical fixes rather than blindly adding records or making changes without understanding the cause.

Whether you're configuring a new sending domain, migrating email infrastructure, or troubleshooting an existing setup, I'll help you identify the issue and work toward a reliable solution.

Let's troubleshoot your email setup. Tell me what you're experiencing, which email provider or server you're using, and what you've already tried.
