What is the best strategy for brainstorming content marketing outreach?

Some things to consider during the brainstorming stage are:
Strategies for choosing your targets, what you will offer them, and how you will present it.
Examples of targets include large media sites with a high number of visitors or followers, individual influencers such as YouTube personalities with many viewers but no traditional publication affiliation. The outreach strategy should vary accordingly depending on who the target is. If the target is a person or vlogger on social media platforms like YouTube and Instagram then their platform should be used in conjunction with more conventional channels like email, phone calls, or even snail mail to increase your reach.
