Newsletters—what type do you like?

I have been planning to start a newsletter for some time now. What will I put in it? That is a question I don’t yet have the answer to. Should it be on history? Religion and spirituality? My books and writing? Or on a combination of all these?

What should be its format? Now on this I have some thoughts. I get a number of newsletters, and there are many that I don’t read, or that I only read occasionally. I am interested in their content, but I don’t like the format. Below I’m making a list of the type of newsletters, in the order of those that I like best.

1. The type I always read, is one that opens completely in the body of the email. I don’t have to click on a link, but can read everything straightaway. I don’t care if there are pictures or not, this is the type that always gets read.
2. Those that provide the first para of a topic, and one has to click on a link to read the whole. If there are several such topics, I’ll rarely click on all–maybe just one or two.
3. Those that provide a link, with a very brief idea of what it contains. I’ll read this if I am really interested in the topic.
4. Those that hardly provide any information in the body of the email. A click on a link opens to a video, where some so-called expert is speaking–and the video goes on and on, with the information at the end. I can never wait till the end of the video, and once having tried it, I never click on similar links again.

What kind of newsletters do you like? And what topics interest you? I’d really like to know.
