Gratona uses Mailgun for transactional email delivery. Review Mailgun's current plans and limits before choosing an account. Once you have created your Mailgun account and logged in, click on "**Send**" on the side menu to expand and show more options then click on "**Sending**" and select "**Domains**". Click on the URL under the Name column in the domains table. Alternatively, if you do not have a custom domain set up, you can use the Mailgun Subdomains option.

Once you click on the domain name, you’ll be redirected to a page displaying your domain Information. To get the SMTP credentials click on the SMTP credentials tab. If you do not remember the password, you can use the option of resetting the password.

Open the account menu at the bottom of the sidebar, select **Organization settings**, then open **Email & sender**.

Use the **Mailgun delivery** section to enter your Mailgun information.

The From Name and From Address should be your organization’s name and email address. The hostname is the SMTP hostname, the login is the Default SMTP Login, and the password is the Default Password from Mailgun. Once you’ve filled in all the information, click **Update**. Now, Gratona will send emails through your Mailgun account.
