Direct Response Copywriter on High-Converting Emails. Part 3. Subject Lines.

There are two things people look at when they see an email.

The person it’s coming from … or the company.

Then the subject line. The former can be more important so make sure you get that part correct. It just has to be clear and consistent.

The subject line is also important.

An email subject line is a headline. It’s essentially the same as the copy on the outside of a direct mail envelope.

Some companies use no copy on the outside of an envelope. I’m not a big fan of that method. You can leave the subject line empty in an email and, again, I’m not a big fan of that.

I see lots of stupid subject lines in email marketing. Usually some ridiculous promise or something sophomoric. I like sophomoric humor but not in serious email marketing.

The subject line is an exercise in writing direct response headlines. As such, I refer to the John Caples headline writing formula.

CURIOSITY + SELF-INTEREST = COMPELLING APPEAL

John Caples, in case you didn’t know, was a superb direct response copywriter. One of his copy cubs, Gary Bencivenga, goes one step further with headlines …

Interest = Benefit + Curiosity

Let’s say you own a restaurant and you want to send an email for New Year’s Eve. You might write something like …

We’ve got something super-special for December 31 this year. If you’re interested in something fun, you’ll open the email.

For a golf-related email, I might write:

A long-drive champion just used this driver to hit the ball 402 yards in a competition …

OK … that subject line might be a bit long. But I want you to write email subject lines that pique curiosity based around a benefit. It’s a proven direct response copywriting technique.

The headline writing has only just begun. I routinely see hundreds of emails with a decent subject line but NO HEADLINE IN THE EMAIL. Crazy. Again, use the formulas above for the headline in the actual email.

If it’s a longer email, break up the copy with carefully-written subheads.

Just remember that subject lines are headlines. And if you can test these, all the better.
