Founder, YourDMARC

Shanky Gupta is the founder of YourDMARC. He leads the product: DMARC report monitoring, hosted DMARC, SPF, MTA-STS and BIMI records, look-alike domain monitoring, and the free DNS and email security tools on this site.
His focus is getting domains from p=none to p=reject without breaking legitimate mail, and keeping them there as senders change.
Shanky Gupta is the author of record for the YourDMARC blog and the knowledge base. For setup steps by sender, see the DMARC guides by platform.
