How to Curate Newsletter the Efficient Way Without Feeling Burnout?

Hi,

I just finished writing the 6th issue of my newsletter (incomelist.co) which I will send tomorrow to my newsletter subscribers. Income List is a newsletter for creators, makers and marketers.

It took me almost 8 hours from researching to writing the 6th issue. I believe it shouldn't take that much time. And that's the major challenge for me.

How do you curate your newsletters quickly? What tools and resources do you use? Any tips, guides, feedback?

I will also appreciate if you show some love to my newsletter (incomelist.co).
