Test your email designs on +40 real devices for FREE!

Hey PH! 👋

We just shipped something we've been wanting forever: Email Design Checker

Here's the problem: You spend hours designing an email, hit send, and it looks broken on Outlook. Or lands in spam. Or has a dead link. Or not compatible with dark mode. We've all been there.

How it works:

1. Forward your email to our test address (or upload HTML/paste code)

2. Get instant results across 30+ real devices

3. See exactly what's broken and fix it with AI

What we check:

• 📱 Device previews (Gmail, Yahoo, Apple Mail, Outlook, AOL...)

• ✅ CSS compatibility across all email clients

• 🔗 Every link in your email

• ✍️ Grammar & content issues

• 📬 Deliverability/spam triggers

The best part? It's free. No signup required.

Just send your email → see results → share with your team → use AI to fix any issues automatically.

We built this because we were tired of the "send and pray" approach. Now you can ship emails with confidence.
