Email Deliverability Toolkit
9 free tools to keep your email out of spam
Nine free tools covering the DNS your deliverability depends on: SPF, DKIM, and DMARC checkers that grade your config (and generators that build the fix), plus DNS, blacklist, and full deliverability checks. No signup, no metering. From the Truelist team.
Hey Product Hunt 👋
Corey here, co-founder of Truelist.
Deliverability almost never breaks where you're looking. It breaks in DNS records you set up once, years ago: the SPF include from an ESP you no longer use, the DKIM selector that stopped resolving after a migration, the DMARC policy that's been sitting at p=none since the day you created it.
We kept writing the same "go check your SPF/DKIM/DMARC" email to customers, so we turned the whole checklist into free tools. Nine of them:
🔍 Checkers that don't just find your records — they parse and grade them, in plain language
🛠️ Generators that build correct SPF, DKIM, and DMARC records for your setup
🚨 Blacklist + full deliverability checks for the "am I OK?" question
No signup, no credits, no "3 free checks then pay." They're free because everyone with clean DNS makes email better for everyone — and because some of you will eventually have lists to validate, which is the part we charge for.
Confession from launch prep: our own domain-reputation tool caught a missing SPF record on truelist.io a few weeks ago. We fixed it using our own generator. It works!
