Send email from your domain. Stupid-simple API.
Add a domain, set three DNS records, and start sending DKIM-signed, SPF-aligned mail through one HTTP endpoint. No US re-billing. Pay in AUD with GST already in the price. Inbound webhooks coming soon.
A small API. A serious MTA. Yours in five minutes.
Bring your own domain
We generate the DKIM keypair, you publish three DNS records (SPF, DKIM, DMARC), we verify automatically. Sender reputation belongs to you, not us.
One endpoint, one bearer token
POST /api/v1/emails with from/to/subject/body. We build, sign, deliver, and webhook you on bounce or delivery. No SDK to learn.
Australian billing
AUD prices, GST inclusive, ABN on tax invoices. No surprise FX, no US dollar dance, no marketing-platform features clogging the dashboard.
Three DNS records and a curl.
From signup to a delivered email, the full path. Most people get through it in under ten minutes — DNS propagation is the only thing you wait on.
Open an account, add your domain
Pick a sending domain — usually something like mail.yourcompany.com. We generate an RSA-2048 DKIM keypair on the spot and show you the DNS records to publish.
Publish three DNS records
SPF, DKIM, recommended DMARC. Our background verifier checks every 30 seconds. The portal shows ✓/✗ next to each record so you know the moment it's live. (MX is shown too, for inbound receive — that's coming soon.)
Mint an API key, send the curl
Once SPF + DKIM go green, your domain flips to verified. Your first send works the same as your millionth — one HTTP call:
# POST your first email curl https://api.emailrelay.au/api/v1/emails \ -H "Authorization: Bearer emailr_..." \ -H "Content-Type: application/json" \ -d '{ "from": "Alice <alice@mail.acme.com>", "to": ["bob@example.org"], "subject": "Receipt #1042", "text": "Thanks for your purchase.", "html": "<p>Thanks for your purchase.</p>" }'
We sign, deliver, and webhook
We DKIM-sign the message, resolve MX for each recipient, talk SMTP with STARTTLS, and capture per-recipient outcomes. Bounces and delivery notifications land at the webhook endpoint you configure.
Buy credits. One credit = one email.
No subscription, no per-seat tax, no marketing-suite upsell. Pay for what you actually send. New accounts get 100 credits free to test end-to-end before paying a cent. All prices AUD, GST inclusive.
Credits don't expire. Auto-topup available. Higher volume? Custom pricing below $0.0008/email — drop us a line.
The questions everyone sends us first.
Why bring my own domain instead of using yours?
Because deliverability is reputation, and reputation is built on a domain you own. Sending as noreply@yourcompany.com means your customers' inboxes recognise you on day two, not a platform-shared subdomain that bounces between providers.
Can I receive email through emailrelay?
Send only, today. Set SPF + DKIM and your domain flips to verified — that's all you need to send. Inbound is being built next: incoming mail will arrive at your domain's MX, get SPF/DKIM/DMARC checked, and POST as a webhook to whatever URL you configure. Coming soon — no ETA committed yet, but it's the next phase on the roadmap.
How does the credit system work?
One outbound email = one credit, regardless of size or recipient count. Multi-recipient messages still cost one credit per send. Credits never expire. Auto-topup keeps you above a threshold so transactional mail doesn't stall. When inbound ships, received emails will also cost one credit each.
What about GST and tax invoices?
All prices on this page are AUD inclusive of 10% GST. Every payment generates an Australian tax invoice with your ABN, downloadable as PDF from the portal. No reverse-charge nonsense from US providers.
Where is the data hosted?
Australian infrastructure. Customer data, email metadata, and DKIM private keys (encrypted at rest with AES-GCM) live on AU-resident Postgres. Outbound delivery happens from Australian-allocated IP space.
What's not here yet?
Marketing-list / campaign features (we're transactional-first). Drag-and-drop template builders (use your own). SMS — that's our other product, smsrelay.au. List-Unsubscribe one-click is on the roadmap for Q3 2026.
