“Building a deliverability checker – what would make it actually useful for you?”

Hey everyone,

I'm an indie developer working on a personal project to help with email deliverability issues. I've been frustrated by how complicated SPF/DKIM/DMARC setup can be, so I built a tool that checks these for any domain.

Where I'm at right now:

• Scans MX, SPF, DKIM, DMARC, TLS-RPT, MTA-STS, BIMI
• Shows an overall score
• Generates DNS records to copy-paste

What I need help with:

1. If you manage email for your company, what's the #1 thing you wish a tool like this would tell you?
2. Am I missing any critical checks?
3. What would make you trust this enough to actually use it?

Thanks for reading!
