I used to use Mailchimp for my email marketing campaign, but they have changed a lot of things and restricted features that were for free in the past. That is why I wanted to replace it with another tool with the essential features I used in Mailchimp, and i found out that Inbox can totally replace Mailchimp and it has additional interesting features that MC doesn't, so it was no brainer to buy this deal. The user interface could be improved, but as long as it works out of the box, it is no problem with me!

Looking forward for the roadmad, keep up the great work!
