I plan to email my subscribers once a day,so I will need a lot of valuable content. Where exactly would I find them? What are some good places to go to? I mean, I can probably come up with a lot of information from my personal experience, but that's a very limited amount and I will need a lot more fresh content.
I also see people sending motivational emails and emails similar to those that aren't related to the main topic. Do you do any of that? How useful is it?
What type of emails do you send besides those that are content based or only related to your category?
