SMTP thatactually delivers.
Open Mind Labs is an SMTP relay for the mail your product has to get right — receipts, resets, invoices, alerts. Point your app at our server, authenticate your domain, and watch the logs instead of the spam folder.

Endpoint
smtp.omldesign.com
Four lines of config. No rewrite.
It is plain SMTP, so whatever your stack already uses — Nodemailer, smtplib, PHPMailer, Laravel, Django, WordPress — keeps working. Swap the host, port and credentials, and you are sending.
import nodemailer from "nodemailer";
const transport = nodemailer.createTransport({
host: "smtp.omldesign.com",
port: 587,
secure: false, // STARTTLS upgrade
auth: {
user: process.env.OML_SMTP_USER,
pass: process.env.OML_SMTP_PASSWORD,
},
});
await transport.sendMail({
from: "billing@yourdomain.com",
to: "customer@example.com",
subject: "Your receipt",
html: "<p>Thanks for your payment.</p>",
});Connection details

Your existing SPF and DKIM records stay valid until you cut over. Add ours, verify, flip the host — no downtime window, no dual-sending period.
Everything the mail needs. Nothing it doesn't.
No campaign builder, no drag-and-drop templates, no contact lists. One job: getting your application's email into the inbox and telling you the truth about what happened to it.
Domain authentication
Add a domain, copy the generated SPF, DKIM and DMARC records, and we verify them for you. Green ticks or a plain explanation of what is still wrong.

Per-app credentials
Issue a separate SMTP username and password for each app or environment. Rotate or revoke one without touching anything else.

Real mailboxes
Every plan includes mailboxes you can actually receive on, not just a write-only relay. Send from billing@, reply from support@.
send + receive
Delivery logs you can read
Every message with its status, recipient response and queue ID. When a customer says they never got the invoice, you can say exactly what happened.
per-message trace
REST relay API
Prefer HTTP to a socket? Post JSON to the relay endpoint with an API key and skip the SMTP client entirely. Same domains, same logs.
http + smtp
TLS by default
STARTTLS on port 587 with TLS 1.3, enforced. Credentials never cross the wire in the clear, and we do not read your message bodies.

Sending in under an afternoon.
The only step you cannot rush is DNS propagation, and that is usually minutes.
Create your account
2 minutesPick a plan, confirm your email, and you land in the dashboard. Nothing to install and no sales call in between.
Add and verify your domain
one DNS visitWe generate the exact SPF, DKIM and DMARC records for your domain. Paste them into your DNS, hit verify, and the dashboard tells you which record is still missing if one is.
Issue SMTP credentials
instantCreate a username and password per app or environment. Drop the host, port 587 and those credentials into your mail config — that is the whole integration.
Send and watch the log
ongoingEvery message shows up with its status, the receiving server's response and a queue ID you can quote to a customer. Daily volume against your plan limit sits on the same screen.
Priced in kwacha. Billed per month.
A flat monthly fee and a daily send limit — no per-email metering, no surprise overage invoice at the end of a busy month. Six-month and annual billing are available at checkout.

Before you switch.
The things people ask us on the first call.
No. We handle transactional mail — password resets, receipts, invoices, order updates, system alerts. There is no campaign builder or contact list here, and bulk marketing blasts are not permitted on the shared infrastructure because they put everyone else's delivery at risk.
Talk to someone who runs the mail server.
Migration questions, volume above the Team plan, a deliverability problem you inherited — tell us what you are sending and we will tell you honestly whether we are a good fit.
