Senders

Senders are the foundation of your email sending deliverability. Each sender consists of two key components:

1. From Address: The sender name and and sender email address that recipients see in their inbox
2. Sending Domain: The sending domain that establishes your sending reputation to inboxes.

Note: If you are using an ESP provider other than OneSignal, senders must be managed directly through your ESP's platform.

Setup your first sender with our guide on how to setup email

Setting up additional senders

1. Navigate to Settings > Email > Senders
2. Click "Add Sender"
3. Enter a sender name and sender email that you'd like for your users to see in their inbox
4. Enter your sending domain (we recommend using a subdomain) and configure your records (How to configure your DNS records) Note: It may take a couple minutes to auto-configure your domain.
5. Start sending with your new identity by going to Messages > New Email > Sender and selecting your sender from the dropdown.

From addresses vs. Senders

From addresses are the sender name and sender email that shows up in an inbox. You can have multiple from addresses in a single sender. The from addresses will all share the sending domain of the sender. For example, if you have a marketing sending domain (e.g. mail.fatsquirrel.com) that sends both newsletters and promotional emails, you may want to create a from address for your newsletter (Newsletter, [email protected]), and another from address for your promotions (Promos, [email protected]).

Senders , unlike from addresses, will each have a unique sending domain. (e.g. mail.fatsquirrel.com vs. notifications.fatsquirrel.com). It's helpful to create a new sender when you want to isolate the sending reputation.

Default sender

Your default sender is sender that is default selected when starting an email. If you have multiple senders, you can select to send from a different sender. To change your default sender, select the action menu on a from address, and select set as default.

Best Practices

We strongly recommend creating at least two senders with two sending subdomains, one for transactional emails, and one for marketing emails.= (e.g. mail.maggie.com, and info.maggie.com). This separation helps protect your transactional email deliverability from being affected by marketing email performance.
