In Settings / Tracking Emails, when you edit your email template you can optionally choose to Verify DKIM and Verify SPF.
This is only an option after you've verified your email address.
What is DKIM?
DKIM is a DNS-based email authentication that allows Pirate Ship to prove we have permission to send email on your behalf.
You'll need access to your domain name's DNS settings to add a DKIM record. These are usually available in the dashboard of wherever you bought your domain name. The exact instructions are available in Pirate Ship when you click the Verify DKIM button.
What is SPF?
SPF is yet another type of DNS-based email authentication, which lets Pirate Ship prove we're sending emails on your behalf.
Just like DKIM, you'll need to add a DNS record to your domain name. The instructions are available when you click the Verify SPF button in Pirate Ship.
