No limits. No per-email fees. Fully managed.
DriftSpike gives you a dedicated SMTP server and REST API — so you can send unlimited emails from your own domain, without touching your Microsoft 365 or Google Workspace setup.
Cancel anytime · No setup fee · Onboarding included
Send 100 or 100,000 emails a month. Your cost never changes. No surprise bills, no volume caps, ever.
Every client gets a dedicated VPS — your own Postfix SMTP server. No shared pools, no data exposure, no neighbours affecting deliverability.
One POST request with your API key. Plug it into any app, platform, or internal tool in minutes. Supports all email types.
Keep reading and replying from Microsoft 365 or Google Workspace. DriftSpike handles outbound sending only — your inbox stays exactly where it is.
SPF, DKIM, and DMARC are configured for you. Every email is signed, verified, and routed directly — no middleman, no blacklist risk.
Server uptime, security patches, DKIM rotation, IP monitoring, SSL renewal — all handled by the Strucureo team. You send emails. We handle everything else.
Private safe area infrastructure built for scale and security.
No third-party access — email content never passes through AWS, Google, or any external provider.
Each client gets their own scoped key. One key cannot access another client's data or logs.
All traffic encrypted in transit on port 587. HTTPS strictly enforced on the API layer.
Server patching, DKIM rotation, IP monitoring, and blacklist checks handled entirely by our team.
DriftSpike is a product of Strucureo — a managed infrastructure team.
No server knowledge required. The Strucureo team handles the entire setup — you just start sending.
Choose the plan that fits your volume and number of domains. Not sure? Start with Standard — it covers most teams and works alongside any existing mailbox.
The Strucureo team provisions your dedicated VPS and installs the full mail stack — Postfix, OpenDKIM, SpamAssassin, TLS, and Fail2Ban. Your server is private, isolated, and configured for inbox delivery from day one. No action needed on your end.
Strucureo will give you exactly three DNS records to add in Cloudflare — or wherever your domain lives. SPF, DKIM, and DMARC. That's it. If you're on Standard or above, we configure split routing so your M365 or Google inbox keeps working normally.
You'll receive your API key via your Strucureo dashboard. Plug it into your app, tool, or platform. Send your first email with a single POST request.
Every email is logged with timestamp, recipient, status, and message ID. Check delivery status via API. Upgrade your plan any time as your volume grows.
One flat monthly fee. No per-email charges. No hidden costs. Managed entirely by the team at Strucureo — no DevOps knowledge required.
Set up takes less than a day. Onboarding is included with every plan. Built by Strucureo. Trusted infrastructure, personal support.
