I tried every top email marketing tool

Interesting point about charging for unsubscribed contacts!

I am building an Open Source email marketing platform (https://www.keila.io) and our current pricing model only considers the amount of emails you send, not the number of contacts/subscribers.

I've been thinking about switching to charging per contacts instead – and I probably wouldn't have considered not including unsubscribed contacts if they're still stored on the platform. But now I will, thanks!

I haven't figured out email marketing yet for my startup, but I'll give Kiela a try. Love open source, and would rather pay for emails then contacts. And mailchimp sucks.
