Hi Product Hunt! 👋 I'm thrilled to share Mail Tool Hub with you today. The Problem: While juggling various full-stack web development and freelance projects, I constantly found myself needing to run quick email deliverability checks, verify syntax, or test spam triggers for outreach. I realized that almost every tool out there is either buried under aggressive, clunky display ads, hidden behind a $30/month paywall, or requires a tedious signup process just to check a simple SPF record. The Solution: I decided to build the exact platform I wanted to use. Mail Tool Hub is a curated directory of 17 free, private, and lightning-fast utilities designed specifically for developers, founders, and marketers. I focused heavily on building a clean UI and delivering immediate, server-side results without the bloat. A few highlights from the directory: AI Email Spam Trigger Checker: Paste your copy and instantly see if you are using high-risk urgency triggers or shady formatting that will land you in the promo tab. Technical DNS Utilities: Check SPF, DKIM, and blacklist status in seconds. Generators & Extractors: Easily map out permutations or extract emails from bulk text. The entire suite is completely free to use with no account required. I would absolutely love to hear your feedback on the UI, any additional micro-tools you'd like to see added to the directory, or how it handles your specific deliverability workflows! I'll be hanging out in the comments all day to answer any questions. Cheers! 🚀

I built 17 free email tools. What should I build for tool #18?

Hey everyone! Today I launched Mail Tool Hub, a completely free directory of 17 email deliverability and verification utilities (spanning everything from an AI Spam Trigger Checker to SPF/DKIM validation).

My goal is to make this the ultimate, centralized toolbox for founders, marketers, and developers so no one has to pay a $30/month subscription just to check a DNS record or clean a list.
