I use a service called OnDMARC (https://ondmarc.redsift.com/)for managing email spoofing/delivery. They have a suite of tools for managing and monitoring spf/dkim/dmarc. Nothing you couldn’t do yourself, but they make it easy. They also have a couple of cool extras like “dynamic spf” which lets you expand beyond the standard spf record length.
