For a self-hosted app to send beautiful email newsletters, look no further than Sendy. It’s a PHP and MySQL based app that’ll run on your own servers, and it shouldn’t be any more difficult to setup than a new WordPress install. Once it’s up and running, you can use it to create rich email newsletters with your own templates, and can use autoresponders to automatically send emails.
What’s more, you can setup multiple brands inside your Sendy account. That’ll let you send emails to all the list you need for multiple products or companies. You can even white label Sendy, give your clients access, and host your own email sending service for each of them. Sendy might not just save you money on sending emails; it might make you money, too.
Sendy Pricing: $59 for a Sendy license, then around $0.0001 per email sent via Amazon SES ($1 for 10.000 emails)
