[Copy Writing] How do you come up with content for your products?

For us, it's split testing. We always try to create multiple copies of what we think can work and then let data choose the winner. We also run surveys to our customers asking them what CTA's work for them.

I would suggest writing what you think makes sense, then make a variant and split test them, run the test for few days then select the winner and remove the loser, then from the winner make another variant and redo the process. It would take some time but you'll keep getting closer to your target markets needs.
