How to Configure SPF, DKIM, and DMARC on my emails

I need some guidance on how to Configure SPF, DKIM, and DMARC on my emails, Many of my emails are not being delivered through Outlook. I get this response, “ suspects your message is spam and rejected it.”

I tried to use the DNS Wizard but I have no idea how to create a record or know my IPv4 and IPv6 records for my domain or what policy to choose. Same with the DMARC. Also on DKIM, I have no idea what a DKIM public key is or the DKIM record content from my email provider
