Ask HN: What are the best email marketing tools out there?

You are asking a very broad question without really indicating what your requirenments are.

I use Mailchimp for my project https://dndemail.com. It has been a great way to launch my solo project. MC has been great primarily because it is:

1. Flexible 2. cheap 3. easy to implement API

I use the api to push the email address of new sign-ups into Mailchimp.

In Mailchimp I have an automated DRIP campaigns that start emailing the users with regular emails about how to use my app and take advantage of all the features.

I can update the user's marketing channel in Mailchimp depending on their actions in my app. For example, if someone cancels their subscription, I trigger a Mailchimp email asking for feedback.

I've used MailChimp a lot and it's good Campaign Monitor is awesome from a templating standpoint. Sendy is by far the cheapest and is self hosted (I haven't used this so can't say whether it's any good or not)

MailerLite. Found it much easier to build an email welcome series automation sequence compared to Mailchimp. And it is free for 1,000 active subscribers.

Drip. Mailchimp is overrated.
