Alternative to Sendy for email campaign or any other suggestions

I am using AWS SES to send out mails for campaign. I want to have some user interface where I can draft and send emails to subscribers. Currently I am using the Sendy for this. As sendy is in still development stage, it's not fit for me. Is there any alternative to sendy? Any service which can be integrated for AWS SES? Or can I use workmails for this?
