I've used beehiiv for a little over a year after a stint using mailchimp I find the beehiiv platform to be user friend with straight forward reporting. I'm unsure if will be continue to be a great tool as it's now a podcast platform but for the time being. I'll continue to use it as an email tool. I've consistently ranked top 30-40% in email open rate and high click through rate. I send my emails 3x a week and readers generally have no issue with signup. I love the built in features that encourage reads to click and engage with the content within the newsletter. Downside, I've driven over 100 subscriptions to other newsletters and beehiiv doesn't appreciate the lift of writers who support community within the platform, it seems that substack is much better at that aspect. Finally the landing page design are outdated and require significant effort to appear halfway decent.
