How Deja Media built a fully automated backend powering SMTP provisioning, DNS automation, warmup dashboards, and deliverability management at scale.
MX Suite — Email infrastructure provider
Manual provisioning and lack of scalability in SMTP, DNS, and deliverability tools.
Backend automation, dashboards, email warmup engine, DNS/RDNS provisioning.
MX Suite needed to manage thousands of email accounts, domains, and sending nodes. The old process of manually configuring SMTP servers, DNS records, and reverse DNS (rDNS) was error-prone and time-intensive.
Onboarding new clients could take days. Scaling to meet demand without automation was impossible, and deliverability required careful warmup and monitoring to maintain inbox placement.
Each client’s SMTP server was provisioned with scripts that configured Postfix, Dovecot, and TLS certificates automatically. No manual shell work needed.
APIs for DNS providers were integrated to instantly create SPF, DKIM, DMARC, and rDNS records for each domain. Full compliance in seconds.
A warmup engine gradually increased sending volume, monitored inbox placement, and performed automatic reputation recovery steps.
A React + Flask dashboard gave clients real-time insights into sends, bounces, reputation, and account health — eliminating guesswork.
Automated provisioning — zero manual server setup.
Faster onboarding time for new domains and clients.
Email warming capacity across multiple client accounts.
By automating every step of the backend, MX Suite scaled to support hundreds of clients without increasing headcount. Deliverability improved, onboarding time shrank from days to minutes, and the platform became a reliable growth engine.
“Deja Media turned what used to be a headache into a smooth, automated machine. Provisioning SMTP and DNS takes seconds, and the warmup dashboard gives us confidence our clients will land in the inbox. We couldn’t have scaled without it.”
