Your subject line decides whether the email gets read at all. Writing one is easy. Writing ten good ones and knowing which two to test is the part that eats a morning.

This prompt from my toolbox does both: ten lines from different angles, then its top two picks for a split test and why.

Give me 10 subject lines for this email, then tell me your top 2 to test against each other and why.

What the email is about: my new PLR video course, The 90-Day Pantry Engineer, a 24-lesson course on building a 90-day family food pantry that buyers can rebrand and sell as their own
Who's on my list: content creators and PLR buyers, a lot of them in the prepping and homestead niches
What I want them to do: click through to the sales page
Real details you can use: 24 video lessons, launch price $12.95, launches Tuesday at 8 AM Central

Mix it up: a few curiosity lines, a few that lead with a specific detail, a few that lead with the benefit, and one that's just a little weird. Keep every line under 50 characters. Only use urgency if it comes from the real details above. No fake "RE:" or "FWD:" tricks.

I ran it in Gemini using my own upcoming launch, The 90-Day Pantry Engineer. All ten came back under 50 characters, the longest at 39. A few I liked:

• “24 food prep videos for $12.95?”
• “$12.95 for a ready-to-sell course?”
• “The ‘pantry math’ your list needs”

Its split-test pick was the first one against the pantry math line: one leans on value, the other on curiosity. It even explained what each result would tell me about my list, which is the useful part of testing that people tend to skip.

Make It Yours!

Swap in your email and your real details.

Give me 10 subject lines for this email, then tell me your top 2 to test against each other and why.

What the email is about: [THE EMAIL IN ONE OR TWO SENTENCES]
Who's on my list: [YOUR READERS]
What I want them to do: [CLICK, BUY, REPLY, READ]
Real details you can use: [NUMBERS, PRICES, DATES, NAMES]

Mix it up: a few curiosity lines, a few that lead with a specific detail, a few that lead with the benefit, and one that's just a little weird. Keep every line under 50 characters. Only use urgency if it comes from the real details above. No fake "RE:" or "FWD:" tricks.

The Line You Should Not Touch!

“Only use urgency if it comes from the real details above.”

Leave that one alone. Without it you get “LAST CHANCE!!” on an email that has no deadline, and your list learns to ignore you.

Full Disclosure

It slipped in one hype line, “The ultimate food security PLR is here.” Cut anything that sounds like a late-night infomercial.

Send yourself a test and look at the winners on your phone before you pick. Under 50 characters is a good rule of thumb, but phones cut lines off at different places. Writing the whole email too? The Black Friday sequence prompt and the welcome sequence prompt pair nicely with this.

Need Something To Send?

Great subject lines need something behind them. That’s where my PLR shop comes in: done-for-you content you can put your name on and use as your own.

Go test your two. Then act surprised when the weird one wins.
