1. Configure Your Sending Domain

Add your Sender Email and Sender Name to the OneSignal email configuration and the optional Reply-To field.

To send email with OneSignal you must own the sending domain.

There are multiple ways to configure your sending domain.

Domain Options include:

1. Purchase a Domain Through OneSignal: Simplify the process by buying and auto-configuring a domain directly within OneSignal.
2. Auto-configure Your Domain: Automatically set DNS records through your domain registrar with login details.
3. Manually Configure Your Domain: Set DNS records yourself for full control. Instructions and support are available on our setup page.
4. Connect a 3rd Party ESP: Integrate with services like SendGrid, Mailgun, or Mailchimp Transactional for those who prefer using existing email service providers.

Option 1: Purchase a sending domain through OneSignal.

If sending on OneSignal mail you have the option to purchase a domain without ever leaving the setup flow.

We partner with a 3rd party domain registry IONOS. All domains purchased in OneSignal will be auto-configured and will require no additional work on your part one you purchase a domain.

This is the quickest way to start sending, particularly if you dont already own a domain or have access to DNS management for the domain.

Option 2: Auto-configuring your domain

To configure the sending domain you can use the Auto Configure option which will add all of the necessary DNS records to your DNS management service to authenticate the sender.

You'll need access to your log in details for the domain registrar you used to register your sending domain. And can use the Auto-configure option so you dont have to manually copy and paste DNS records.

Option 3: Manually configuring your domain

Additionally, we provide the option to set up DNS records manually. For a walkthrough and video guide on how to set up DNS records or create a subdomain, visit our Email Sending Domain Setup .

Option 4: Connecting a third-party ESP

By default, OneSignal ESP will be selected. Optionally, you can connect a third-party ESP to send emails from OneSignal. We support integrations with Sendgrid, Mailgun, and Mailchimp transactional(Mandrill).

Follow the setup guide for your 3rd party ESP:

• SendGrid Setup
• Mailgun Setup
• Mailchimp Setup.
