The emails behind everyday business

Small messages.
A big part of the experience.

Your software knows when something happens. SignalPost gives it a way to send the email that follows.

Stores & sellers

“Did my order go through?”

Put the receipt, order confirmation or shipping update in motion when your store creates it.

Purchase → confirmation email

Apps & online services

“I need to get back in.”

Send password resets, account confirmations and requested security notifications from your app.

Account request → helpful next step

Bookings & subscriptions

“Can you send me the details?”

Deliver the booking confirmation, invoice or account update your customers expect to receive.

A change → the details they need

Fit delivery into the way you already work

Keep your software.
Connect it to SignalPost.

Your emails can keep their existing content and design. Choose the connection that fits your setup.

For software with email settings

Copy in your SMTP settings.

If your website, store or business tool lets you choose an SMTP server, add the server address, username and password from SignalPost.

  • Keep the templates in your software
  • Send complete emails with attachments
  • Use a separate connection for each app
See the setup steps
For teams building an app

Send through the API.

Have your application submit the sender, recipients and content to SignalPost. Get an acceptance receipt, then follow the delivery results.

  • Send text or HTML email
  • Use request keys to safely retry API submissions
  • Connect delivery events to your own systems
Prepare an API connection

Your software needs configurable SMTP settings or an HTTP API integration. For SMTP, complete emails must be under 10 MB, with up to 50 recipients per submission. Ask us about your setup.

When someone says, “I never got it”

Start with an answer.

Review the recipient, submission time and delivery result in one place. See whether the email is waiting, has been accepted for delivery, or reached the recipient’s email service.

If something goes wrong, open the available server response details to help work out the next step.

Take those answers to your other tools
Verify your sending identity.

SignalPost shows the domain records you need and their verification status before sending.

Give each app its own access.

Create a connection for each app. Disable one when you need to stop its access.

Keep repeat attempts under control.

API request keys let your app retry the same submission without reserving the allowance again.

Useful inside SignalPost. Useful outside it.

Your delivery data
belongs in your workflow.

Answer a customer’s question, share a report with your team, or feed your own reporting system. Every delivery allowance includes the same standard export and reporting access.

CSV

Open it in a spreadsheet.

Download recipient records with message references, subjects, statuses and submission times.

Event exports

Keep the detail behind the result.

Export delivery events with timestamps, message references and available response details in JSONL format.

Webhooks + API

Keep your other tools informed.

Send signed event updates to your systems, or retrieve records with a reporting API key.

Owners and admins can export reports from Email delivery. Developers can retrieve events incrementally and connect signed webhooks through Integrations. We can help you find the right connection.

A clear path to your first test

Three steps.
Help when you need it.

  1. Verify your sending domain.

    We show the records to add to your domain settings and check their status. Ask your domain manager or our team if you need help.

  2. Connect your software.

    Create an app connection, then add the SMTP credentials to your software or give the API details to your developer.

  3. Check a test email.

    Once delivery access is enabled, send from a verified address and review the result before moving your regular emails across.

How sending and billing work

This is a monthly allowance, not a bill for actual usage. Plans renew monthly until canceled. Each recipient accepted for sending counts once, including To, CC and BCC recipients. Retries do not count again. Sending pauses at your allowance; there are no automatic overage charges. Unused sends do not roll over. You can buy extra capacity in your account for the full price difference; your monthly renewal amount increases too. Later bounces remain billable. Applicable taxes are shown in billing. Up to 10 MB and 50 recipients per submission. Sending and purchases open after delivery setup is verified.

Before you connect

The practical questions.

Is this different from SignalPost email marketing?

Yes. SignalPost email marketing helps you create campaigns, manage audiences and automate follow-up. Email delivery connects to software that already creates your receipts, account messages and notifications. You can choose delivery on its own, with separate billing. See the email marketing platform.

Do I need a developer?

If your software lets you enter an SMTP server, you can copy in the settings from SignalPost. A developer can connect a custom app through the API. Domain verification may need help from whoever manages your domain. Ask our team about your software.

Can I send newsletters and promotions through the relay?

This relay release is for requested account, order and notification emails. For permission-based newsletters and promotions, use SignalPost email marketing.

What happens if my sending volume changes?

Your account warns you at 80% usage. You can buy extra capacity in your account for the full price difference; the larger allowance becomes available after payment and raises your monthly renewal amount. Previously counted sends stay counted. To reduce capacity at renewal, contact our team.

At the limit, new emails are not accepted until you add capacity or the allowance renews. Already accepted emails remain queued for delivery. There are no automatic overage charges, and unused sends do not roll over.

Does “delivered” mean it reached the inbox?

It means the recipient’s email service accepted the email. The receiving service decides where it goes. Relay reports do not infer human reading or inbox placement; relay mail does not add open-tracking pixels or rewrite links.

Can I buy through a cloud marketplace?

Cloud marketplace purchasing is planned and is not available yet. Direct connections use your SignalPost account.

Can I start sending today?

You can review pricing and prepare a connection now. Sending and checkout open after the delivery setup is verified. Contact our team to arrange access.
