Tight integration, reliable service

I use this plugin on an e-commerce site built on WordPress — we use it to send out all transactional emails (“Thank you for your order” / “Your order has shipped” / “Your subscription has billed” / abandoned cart emails / etc.)

It is working great. Tweaks to email templates are easy to lay down and the stats are kept right in our dashboard, making it easy to keep tabs on how effective everything is. It has been very easy to resend emails to customers to tracking down order details.
