InboxGreen - Free email deliverability checker for SPF, DKIM & DMARC

Most senders don't know their SPF, DKIM or DMARC is broken until emails start bouncing or landing in spam. InboxGreen checks your domain's DNS records in seconds, no login needed. See what is passing, failing, or missing. The FixKit generates ready-to-paste DNS records for Cloudflare, Namecheap, Google Workspace and Microsoft 365. Includes 28 free DNS tools: blacklist checker, DKIM finder, SPF tester, DMARC analyzer, and more.
