We love to experiment with new ideas at SparkPost. With Labs, we release new and experimental features for you to try out. Give them a go if you're as excited about pushing email to the next level as we are. Due to their experimental nature, here are some details to keep in mind when using Labs features:
Labs features aren't versioned, and are mainly available under the /api/labs/ path, rather than the normal /api/v1/ path. When it makes sense, some Labs features are available under existing API endpoints.
Lab features are experimental and subject to change. We may decide to change the behavior or discontinue it at any time. We also may decide to incorporate Labs functionality into the core supported product.
Normal support channels or SLAs are not available for SparkPost Labs. You can provide feedback via this Google form.
