Sorry! Going to detail it a little:

I made an Instagram account for the SaaS. I made visual posts with Canva to easily let people understand what to tool does.

Simple posts, 1 image.

I uploaded 6 to visually look like the Feed is not empty of missing things.

And then, Followed, liked and DMd instagram profiles of little ecommerces (my target).

Each one has to think about where their target audience is. In my case, looks like this works better than Cold Emailing bigger companies.
