Does Mandrill offer a free trial or demo?

Yes. Mandrill offers a free trial account with 2,000 email credits to all MailChimp users. After the 2,000 free email credits have been used, users need to upgrade their Mandrill account, which requires a monthly paid MailChimp plan.

You can add Mandrill and begin the trial in your MailChimp account.

Trial Mandrill plans are limited to an hourly quota of 25 emails/hour. Exceeding the hourly quota will cause those emails to be queued and sent as the hourly quota resets. Trial accounts can also take advantage of Mandrill's inbound email processing, but can only receive 100 inbound emails/day - after reaching this limit, inbound messages will not be processed or received. These limits are removed for paid Mandrill accounts.

Mandrill is designed to be flexible and customized depending on your existing framework or application. The best way to demo Mandrill with different frameworks or integrations is to sign up for a free trial account and begin sending email. Use Mandrill's test mode to generate emails using our API or SMTP integration and simulate bounces, unsubscribes, and spam complaints without actually sending live email.

Mandrill counts each recipient as one email for credits and billing. For example, if you send one SMTP message to five recipients or include five recipients in your API request, we'll count that as five email credits toward your monthly limit.
