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
InboxStack is an email deliverability intelligence platform built around Brain, a proprietary causal AI engine that identifies why emails miss the inbox — not just that they did. Most deliverability tools stop at monitoring: they show a drop in inbox placement or a blocklist hit and leave you to investigate. InboxStack goes further, correlating signals from your ESP, DNS authentication records (SPF, DKIM, DMARC), Google Postmaster Tools, Microsoft SNDS, and 50+ blocklists through a causal knowledge graph built on a 22-year deliverability knowledge base — tracing the actual root cause, whether it's a DKIM misalignment, IP reputation dip, or content trigger.
Onboarding starts with forwarding your email headers for an instant DNS/auth audit, no migration required. Teams that want ongoing monitoring can connect their ESP and Postmaster accounts, with optional seed testing for real inbox-vs-spam placement data.
Built especially for digital agencies and ESP's.

About
JavaScript is a scripting language and programming language for the web that enables developers to build dynamic elements on the web. Over 97% of the websites in the world use client-side JavaScript. JavaScript is one of the most important scripting languages on the web. Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote. Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes.
