Why use a domain in your name rather than shared domains (see Why should I customize my sending domain name in Sarbacane Campaigns?).
How to choose between a subdomain of your domain name and a domain bought with Sarbacane (see Which method should I choose to send with my own domain in Sarbacane Campaigns?).
How to set up a sending subdomain by delegation (see How do I set up a sending subdomain in Sarbacane Campaigns?).
The role of the SPF, DKIM and DMARC DNS records in deliverability.
