Q: I was on the fence but the purchase fell short due to the limited number of domains given the sending limits in this offer.
I have a Microsoft Office365 Plan with a few users (domains), which has most of the settings, including DMARC and cloud storage of all my e-mails.

Microsoft Office365, Does not have any inbuilt DMARC, implementation or analytical tool. You have to use third party tool such as KDMARC to visualise how your emails are landing in the inbox of the users.
The KDMARC is for unlimited users but has a cap on volume and domains, Regarding the limit on domains, you can always buy an addon domain ($5/month) on the top of AppSumo deal.
Do let me know if you still have any questions.
Noted,
But according to your DMARC checker tool on your website, it found the DMARC records for my domain below:
v=DMARC1; p=reject; pct=100; rua=mailto:rua@domain.com; ruf=mailto:ruf@domain; fo=1.
Microsoft Support helped me setup the DMARC for the domain so it's included in my 365 license. It it true that Microsoft doesn't have any analytics or visualisations. They refer to third parties for those services.
