Mailcoach is really great at what it does, which is twofold:
And it's a specific tool for folks who feel comfortable getting their hands dirty spinning up servers, dealing with API keys, and not having 24/7 support.
If you're looking for a PHP plugin rather than a full-featured tool, then Mailcoach is very good at that.
Buttondown is a cloud solution: you don't need to understand sotware or manage your own installation or anything like that to get your newsletter off the ground. All you need to do is register, log in, and you're off to the races.
In addition, Buttondown offers a handful of features that Mailcoach can't due to its self-hosted model:
|Analytics||Dive into individual email performance, client information, and more|
|Drag and drop image uploading||Images are uploaded quickly and securely.|
|Email scheduling||Write an email on Thursday and send it out on Friday; queue up an entire month's worth of letters.|
|Clean, usable design||Design is more than just how it looks, and Buttondown is designed top to bottom to make it easy to use.|
|Autosaving||Never worry about accidentally closing a tab ever again.|
|Privacy-first||Buttondown is GDPR-compliant — and then some. I don't collect any data about you (or your subscribers), and you can turn off pixel tracking and link tracking with a click of a button.|
|Free for your first hundred subscribers||Because it shouldn't take a credit card to get a newsletter off the ground.|
|Archives||Because sometimes you don't want your newsletters to disappear into the ether.|
|Embeddable widget||Have your own personal site? We'll hook you up with the code.|
|Markdown support||Buttondown also supports HTML and good old fashioned plain text: whatever your preference is!|
|Free RSS support||I mean, some people _really_ like RSS.|
|Smart embeds||Embed tweets, Youtube videos, and more just by dropping in the link.|
|First-party API||Everything you can do on Buttondown's interface, you can also do with our REST-ful API.|
|Paid subscriptions||Buttondown makes it easy and painless for you to get paid for your newsletters. Want to have a free tier? That's possible, too!|
|Third-party integrations||Setting up your Buttondown account to work with Zapier, IFTTT, Weebly, Squarespace, Ghost, and more.|
|Multiple newsletters||Want to run more than one newsletter from the same account? Buttondown's got you covered.|
|'Pay what you want' mode|
