If you don't have an SPF record yet, add one for your domain. At a minimum, the value should be the following if you're only sending mail through Mandrill for that domain:

If you already have a TXT record with SPF information, you'll need to add Mandrill's servers to that record by adding include:spf.mandrillapp.com in the record (before the last operator, which is usually ?all, ~all, or -all).

In some domain providers, SPF records have been depreciated, you might need to create the same value as a TXT record.

Add a new TXT record with the name mandrill._domainkey.yourdomain.com.

Replace yourdomain.com  with the domain, you are using (this may differ depending on your provider and the domain part might not be needed).

The value for the record should be one of the options listed below. There are two options because the record contains semicolons and some DNS providers escape semicolons for you while others require you to do it when setting up the record.           

With semicolons escaped:

 With semicolons unescaped:

Let us know if you need any clarifications on the above! 😊

*Note: since these settings are not part of the Viral Loops dashboard, we can only provide you the right (generic) values and possible errors that prevent you from setting everything right (except the first verification step that we can do manually for you if needed). Each provider has its own fields, settings, and format, therefore if you face difficulties/problems, you need to contact their support team for additional assistance.
