10x better than Mailchimp, Substack, Mailerlite, Tinyletter, and others. Trust me, I've tried them all. Easy to set up, but lots of options for customization if you want them.

Just the best newsletter tool out there. The new pricing model is less generous than before, but even with that in mind it is still worth every penny.
