In order to send email campaigns with Mailigen and prevent your emails from being blocked or looking illegitimate you will have to configure SPF and DKIM. They work together to authenticate your emails and making them look as if they originated directly from your domain.
Within Mailigen you will have to follow the instructions in order to create the SPF and DKIM records needed for email authentication. Once Mailigen provide you with the records, you will have to create them in your DNS.
