Hello @PamelaM2545 ,
Regarding your domain, I'd definitely advise checking out our Community's FAQ on email authentication, which includes how to setup your account for self-authentication. If you don't have an IT person you can work with, or a website support team you can reach out to, you may want to consider sticking with the ccsend rewrite we offer.
As far as getting started, I'd recommend following along with this article when you're creating your first email, and this article when making your first sign-up landing page.
When you have the time, we also have a Getting Started guide (also available in video format), with relevant links for newcomers using the system. You're also welcome to call our general support so you can work 1:1 with an agent, and also screenshare while you're logged into the account.
Our Community also has resources under the Get Help and Resources tabs at the top, particularly for the Marketing Digest page and Onboarding Hub pages.
Otherwise, our Knowledge Base has articles available for all the different tools in our system, with written instructions, visual aids, video tutorials, and common troubleshooting steps as well.
