I'm using some of these that are on your list while I'm going to explode all the others, These tools are not for blockchain projects only, they can be applied for every industry where you want to get some leads.

You forgot to add the website creation tools, creating a website to house all your products and services and landing pages is one of the best ways to maximize your marketing efforts.

I recommend:
