250 v1.0 — smtp relay, live
Send email.
That's it.
justsmtp is a transactional email relay on top of Amazon SES. We handle the IAM policies, DKIM rotation and region quotas — you set SMTP_HOST and go.
// npm install nodemailer import nodemailer from 'nodemailer'; const transport = nodemailer.createTransport({ host: 'smtp.justsmtp.com', port: 587, auth: { user: process.env.SMTP_USER, pass: process.env.SMTP_PASS }, }); await transport.sendMail({ from: '"Acme" <hello@mail.acme.io>', to: 'sarah@example.com', subject: 'Welcome to Acme', html: '<b>You are in.</b>', });
· 99.98% uptime· <40ms median handoff· no AWS account required
/how-it-works
Three steps, then you never think about it again.
Verify your domain
Paste your domain. We generate SES-compatible DKIM and SPF records. Usually verifies within a minute of DNS propagation.
Generate SMTP credentials
A user and password pair per environment — prod, staging, that weird branch you forgot about. Revoke any of them from the dashboard.
Point your app at us
Host is smtp.justsmtp.com, port 587 or 2525. Swap it into your existing mailer. Nothing else changes.
/why
The boring things we do so you don't have to.
SES pricing, without SES.
We pass through Amazon's rates with a small relay margin. No surprise markup at 100k.
No AWS account, ever.
You don't touch IAM. You don't approve region increases. The SES sandbox is our problem, not yours.
DKIM rotation on autopilot.
Keys rotate quarterly. We update the records so you never wake up to a DKIM-fail incident.
Logs that don't lie.
Every relay attempt lands in your activity log — sent, deferred, bounced, dropped — with the real SMTP response.
