How do I make a SPF record for Opalstack email?

SPF records can improve the deliverability of your email by letting recipient email servers know which systems are allowed to send mail for your domain.

For Domains Using Opalstack Name Servers

If your domain uses Opalstack's name servers then you can create a SPF record as follows:


Click DNS Records in the control panel sidebar.


Add a new DNS record with the following values:

  • Domain: the domain for the SPF record
  • Type: TXT
  • Content: v=spf1 ~all
  • All other fields can be left at their preset defaults

Save the new DNS record. It should take about 1 hour to propagate through DNS, after which it will be available for checks by recipient mail servers.

For Domains Using External Name Servers

If your domain uses external name servers, such as those provided by your domain registrar or a third-party service like Cloudflare, then you can create a SPF record by logging into their DNS management system and creating a new TXT record for your domain with the following content:

v=spf1 ~all
