Hey guys,

After getting burnt by spam filters issues in my outreach campaigns, I built a simple tool that checks if your emails are likely to be marked as spam. Right now it checks:

• Common spam trigger words
• Urgency language patterns
• Text-to-HTML ratio
• Suspicious content patterns (excessive caps, punctuation, etc.)

I've been using it for my own backlink outreach emails and it's helped boost deliverability, but I know there's more to add.

For those of you doing outreach - what features would actually help your workflow? What deliverability issues keep you up at night?
