Standard Processing SLAs

The timely execution of Mixmax services is critical to enabling your workflows to operate smoothly. The below outlines target SLAs for various features in Mixmax. These features can include email sequences, Salesforce updates, sync events from Salesforce to Mixmax, and evaluating and processing rules. We have built our system to be highly scalable and performant while ensuring your data is secure. As such, here are the performance expectations:


Typically, sequence stages will take under 5-10 minutes to process. Occasionally, they may take up to 60 minutes if there are extreme spikes in simultaneous sequences being sent.


Most rules are executed within 10-20 minutes from when they are triggered. Occasionally, they may take up to 120 minutes if rules are extremely complicated or a large amount of Salesforce data is updated simultaneously (usually via an automated script or app).


Mixmax may limit the number of emails a single user sends in a day to 1,000. This helps ensure users are not rate-limited by Google (we work with Gmail as the underlying email service) and have the most responsive experience on the platform.

System Requirements

The Mixmax Extension is supported in the current stable desktop release of Google Chrome and the immediately previous stable desktop release of Google Chrome.

Example: If the current stable release of Google Chrome (as defined at Chrome Platform Status) is Chrome 90, then the versions supported are Chrome 90 and Chrome 89 for Windows, MacOS, and Linux. Older versions of Chrome may function but are not actively supported by Mixmax.

In addition to the hardware requirements applicable to your operating system, the Mixmax Extension requires at least 8GB RAM installed on your system for optimum performance. Users in lower RAM environments may encounter slow performance. The Mixmax extension also requires that your display supports a resolution with a width of at least 1280 pixels. A narrower display width may result in a loss of functionality.

Mixmax does not support Chromium-based browsers other than the official Google Chrome release.

Other apps that make Mixmax available, such as Station, Shift, Mailplane, and similar tools, are not supported by Mixmax. Contact the vendor for support if you encounter an issue using Mixmax in one of these tools.
