Sentry - AI Email Shield that saves me 69 hours/year (Pre-inbox filtering)
Hey PH! 👋
Alexey here. Like many of you, I have a "public" email for my SaaS. And like many of you, my morning routine used to start with 20 minutes of deleting:
"Quick question..." (Sales pitch)
"Partnership opportunity..." (Link exchange)
"URGENT INVOICE" (Phishing)
I calculated I was spending ~70 hours a year just triaging spam. That's two weeks of dev time lost. Existing filters (Gmail, Outlook) work after the email hits my inbox. I wanted something that stops it before.
So I built Sentry.

🚀 What is it? Sentry is an AI-powered proxy layer for your email. It sits in front of your real inbox (Gmail/Outlook) and filters incoming traffic using LLMs (Gemini 2.0) trained on B2B spam patterns.
🛠️ How it works (Technical):
MX Layer: Point your MX records to Sentry (or use our aliases).
AI Analysis: We analyze sender headers, SPF/DKIM, and body content.
Routing:
Clean: Forwarded to your real inbox via SMTP.
Spam: Rejected instantly.
Suspicious: Quarantined for manual review (via a dashboard).

💰 Results so far:
My inbox volume dropped by 80%.
Phishing attempts (fake invoices/CEOs) are blocked before I see them.
I saved ~1.5 hours last week alone.
🙏I need your feedback: We just launched the Beta. It's free for early users. I'm looking for founders who are drowning in cold outreach to stress-test our AI model.
Does the setup flow make sense?
Would you trust a proxy with your business email? (We don't store bodies, only metadata, but trust is key).
