About

InboxGreen is a free email deliverability checker that tests SPF, DKIM and DMARC records for any domain instantly, no account required. It shows exactly which DNS records pass, fail, or are missing, and explains what each result means for inbox placement. The platform includes 28 free DNS tools: DMARC analyzer, DMARC policy tester, SPF generator, SPF tester, DKIM generator, DKIM checker, DKIM selector finder, blacklist checker, email header analyzer, MX lookup, TXT lookup, WHOIS lookup, reverse DNS, DNS propagation checker, SMTP port checker, IP address info, and more. For teams that need to fix issues, the FixKit provides step-by-step DNS fix instructions for every problem found. The Monitoring plan watches up to 5 domains and sends alerts the moment SPF, DKIM or DMARC breaks. The Agency plan covers up to 30 domains with white-label PDF reports. Built for developers, marketers, and anyone who sends email and needs it to actually reach the inbox.

About

The sendmail Sentrion platform is specifically designed for large, complex environments, but we make a subset of that solution available as an open-source offering. Sentrion is not for everyone, but if you are using open source email for a large complex environment and need an enterprise platform that will enable your messaging roadmap for years to come (virtualization, consolidation, cloud migration, etc.). The Domain Keys Identified Mail (DKIM) Internet standard enables email senders to digitally sign their messages so that receivers can verify that those messages have not been forged. The DKIM sender authentication scheme allows the recipient of a message to confirm a message originated with the sender’s domain and that the message content has not been altered. A cryptography-based solution, DKIM provides businesses an industry-standard method for mitigating email fraud and protecting an organization’s brand and reputation at a relatively low implementation cost.
