The interface is beautiful and IT WORKS, the free analytics provided are just what I want, and the personal service is unmatched.

Plus the notification emails are fun. Sensitive content hidden] clearly has a sense of humor and pours his being into the efforts.

My experience has been great; it's like a breath of fresh air compared to most of the bloated, overpriced email products out there, and there are no ethical qualms either.

The customer service is excellent and Justin is always adding new stuff to the product; he's very transparent about future plans and his organization and attention to detail is impressive.

Seamless integration with domain was very useful also.

Self Employed

Buttondown is an easy to use newsletter platform that packs a lot of features into a simple user interface. Anyone can learn to use it, though it's best for users with some amount of tech-savvy.

Owner, Engineer

With the current feature set, I'd have to set up separate emails manually for those "ignored" emails from before I used the service.

The UI is buggy enough that it seriously detracts from my overall experience.

Wedding Celebrant

The lower level price points don’t have much flexibility for a small to medium list size.

This seems not good for the potential that people might forward the one they receive to others, and that that might come out hard to read on the next reader's end.
