Why Your Killer Subject Line Might Be Killing Your Deliverability

Crafting a catchy subject line is great, but if it’s hurting your email deliverability, what’s the point? Here’s why your “killer” subject line might be the problem:

1️⃣ Trigger Words = Spam Filters Activated 🚨
Words like “free,” “urgent,” or “guarantee” can land you in the spam folder faster than you can say “unsubscribe.”

2️⃣ Excessive Punctuation!!! ❌
Exclamation marks, ALL CAPS, or “clickbait vibes” scream spammy behavior.

3️⃣ Too Flashy 🎯
While creative subject lines grab attention, overly clever ones might confuse recipients or raise red flags with algorithms.

How to Fix It

• Keep it simple and professional.

• Focus on clarity and curiosity, not tricks.

• Test your subject lines with spam checkers before sending.

Your goal? Stand out in the inbox without standing out to spam filters. 🚀

Pro Tip: When I notice a prospect is using a competitor’s product, I’ve simply used the competitor’s name as the subject line—it’s worked wonders for grabbing attention! 🚀
