This guide is only for OneSignal email.
If you are sending through Mailgun, Mailchimp, or Sendgrid, take a look at the Email Troubleshooting to learn more about domain setup for those ESPs.
When you first set up OneSignal email, we recommend sending emails through the provided OneSignal domain. This will help you get sending sooner without having to update your DNS settings.
When you're ready to start sending emails using your own domain, follow the guide below.
If you haven't already set up OneSignal email, follow the OneSignal Email Guide and choose the "Yes, I'll configure my own domain" option.
Provide a point of contact of the person who will configure the DNS settings so we can reach out to them. We'll send them the records that need to be updated (two TXT (SPF and DKIM), two MX, and a CNAME record).
If you've already set up OneSignal email and want to use your own domain instead of the one that we've provided, go to Settings > Platforms > Email. Select OneSignal and Continue.
On the next screen, click the Contact our Support team link to start a conversation with a member of our team. Please provide them with the domain name you wish to use.
We will send you an email within two business days with the DNS records that need to be updated.
Go into your Domain Registrar, and add the TXT, MX, and CNAME records provide to you. Visit the Email FAQs page for information on how to find each record for some of the most popular domain providers.
Let us know that you've correctly updated your DNS settings by replying to the email or contacting Support. Once you have confirmed the changes to your DNS settings are complete, we will finish the configuration on our end, and you can start sending.

New domain? Consider throttling sending to warm your domain
If you are sending from a new sending domain or subdomain, you may want to consider warming the domain to improve deliverability. Follow the Email Throttling & Warm-Up guide to learn more.
