Speed Marketing

The angle here is accelerated learning rather than marketing technique, which is an unusual and genuinely useful distinction to make to a customer who already owns plenty of tactics.

Speed Marketing is about building marketing skills faster, aimed at someone whose efforts keep producing nothing despite real persistence and plenty of material on the shelf.

Sell it on the learning rather than the marketing, because your customer has bought the tactics already and absorbing and applying them is the actual bottleneck. That framing also makes this complementary to everything else you sell rather than competing with it for the same budget. Promote it to subscribers who buy frequently and apply little, which you can usually identify from your own order history, and pair it with Procrastination Killer and Super Time Management.
