I will be the first to admit: Mailchimp is a great tool. It has a ton of features and a ton of power behind it.
There are things you can do with Mailchimp that you'll never be able to do with Buttondown: multivariate testing to see which of four different subjects performs the best, deep integration with Facebook and Instagram ads to optimize your lead collection strategy with eCommerce, a full-blown CRM to track every single click and webpage a customer visits, and more.
If you're in the kind of role where your job means spending your entire day inside your email marketing platform, then Mailchimp is almost certainly a better tool for you than Buttondown.
But what if you're not in that kind of role?
What if bumping your open rate on an A/B tested subject from 6.2% to 6.3% isn't worth the extra $100 a month? What if your main goal is to just maintain a list of subscribers and send them emails, instead of "setting up and optimizing customer journeys?"
Then you may be paying way too much for a tool that's way too complicated for your needs.
Best of all, you can migrate from Mailchimp in mere minutes. Buttondown has a step-by-step guide for migrating from Mailchimp to Buttondown, and here's the deal: if it takes you more than ten minutes, you get a free month of Buttondown.
