Cold email subject lines: 86.6% open rate

Have you ever experienced 86.6% organic reach on any social network?
No? Me either.

But I have experienced it via email.
I also ran an experiment with cold emails and saw over 50% open rate (= organic reach = for free).
My champion subject line was “Invitation for NAME”

Today I stumbled upon a couple of interesting experiments with cold email subject lines by other companies.

So here are the highest-opened cold email subject lines:
1. by Sumo: “hey NAME, quick question”
2. by LeadGenius (86.6% open rate): “I Found You Through CONTACT NAME”

Looks like these subjects can bring you a bunch of new leads for free. 🙂
