DmarcBeacon

Introduction to DmarcBeacon

DmarcBeacon is the smoke alarm for your email deliverability. It continuously monitors your SPF, DKIM, and DMARC records 24/7 and alerts you the moment they break. This service ensures that your emails—whether they are invoices, magic links, or newsletters—reach the inbox instead of being marked as spam. A single broken DNS record can make your messages invisible to recipients, which is why proactive monitoring is essential.

The product offers a free version with unlimited manual scans for developers, making it accessible to all users. For those who need continuous protection, the Pro plan provides 24/7 automated monitoring and instant alerts at an affordable price of $29 per year. DmarcBeacon is designed to be simple, reliable, and free of unnecessary enterprise features.
