Reject: Reject failed SPF emails completely

How to Add An Advanced DMARC Record
Add a DMARC record as you would in the Basic guide above, but instead of clicking Add Record, click Optional Parameters first. Once DMAR configuration is complete, click Add Record.
Subdomain Policy: Set how the DMARC record applies to email accounts with subdomains
DKIM and SPF mode: Setting either of these to Relaxed will allow the DKIM/SPF of a subdomain to pass the check if the DKIM/SPF record is for a different subdomain of the primary domain (or the primary domain itself). Setting to Strict means that the DKIM/SPF must match the exact DKIM/SPF of the specific subdomain
Percentage: Sets the percentage of emails which DMARC will check. It's best to leave this at 100.
Generate Failure Reports When: Sets which emails are included in the DMARC failed emails. Select All Checks to only include emails that fail all SPF/DKIM checks. Select Any Check to include emails that fail some, but pass other of the checks
Report Format: It's best to select ARFR here as it has been specifically designed for DMARC reports
Report Interval: Sets how often a report is sent (86400 seconds is default, which is 24hrs)
Send Aggregate Mail Reports To: Set which email accounts recieve complete DMARC reports (including success, failurs and partial failures)
Send Failure Reports To: Set which email accounts recieve reports of emails which failed DMARC
