Friday Release Notes: Lower Pricing and More Transparency

Like our siblings over in MailChimp, the Mandrill team is celebrating Good Friday today, but we've still got some neat additions for you this week.

Dramatically Lower Prices, No Minimum Fees

This one's already been announced on the blog, so I won't belabor the point too much, but our new pricing is lower for absolutely all of our users, and on average will cut your bill in half. In addition, we made a bunch of changes to our monthly billing and account status screens to reflect this new focus on pay-as-you-go utility pricing.

This is a huge change to our pricing model, but we're still the same team with the same goals. We're just as focused on performance and reliability of our infrastructure, and we'll be doing just as much to innovate and add features to the product at a rapid clip. With nearly a year of experience running Mandrill under our belts, we found some cost savings in how we operate. Who better to benefit from that than our customers? Play around with our new pricing calculator and see!

New Mandrill Status Site

Being a low-level infrastructure service, we knew from the outset that a good status site would be absolutely necessary. In particular, we wanted to solve a problem with the way status sites are traditionally put together. We didn't want our status page to be a sea of green dots with no context. The Mandrill status page needed to be more transparent, and expose details of how the service is put together, using a lot of the same data we use internally to monitor the system. I'm pretty excited by what we've come up with, and you can see it at

We've got another blog post coming next week to provide more detail on how and why we built this site, so stay tuned for more info there.

Adding SPF and DKIM checks to inbound webhooks

And finally, a more traditional feature for the week. Inbound message processing now includes a check for SPF and DKIM, and details are included in the post to your webhook. You can use this information to help verify message authenticity, but keep in mind that SPF and DKIM are optional and many senders don't publish SPF records or sign their mail.
