You can have the best subject line in the world.
You can have the best offer in your niche.

But if you land in the Spam folder or the Gmail "Promotions" tab abyss, you have $0 revenue.

Many founders see a 15% open rate and think, "Maybe my subject lines are bad."
The reality? Your subject lines are fine. Your deliverability is tanked. Google and Yahoo are gatekeeping your emails because you look like a spammer.

If your open rates have dipped below 20%, stop selling and start cleaning.

🎯 Step 1: The "Sunset" Flow
Identify anyone who hasn't opened an email in 90 days. Put them in a specific flow:
"Hey [Name], do you still want these emails?"
If they don't click, delete them. Yes, delete them. A small, engaged list prints more money than a large, dead one.

🎯 Step 2: Text-Only Mode
For your next 3 campaigns, strip out all HTML, heavy images, and "Shop Now" buttons. Send a plain text email that looks like it came from a friend.
Google's algorithm loves conversation; it hates flyers.

🎯 Step 3: The Reply-Bait
Ask a question in your P.S. line.
"P.S. Quick question - which color do you prefer, Blue or Red? Hit reply and let me know."
Replies signal to Gmail that you are a legitimate contact, not a corporation.

Email platforms protect their users, not your business. If you don't respect the inbox, you get locked out.
