Common Questions

What is an active user?

Active users are your users with your extension installed who have visited Gmail in the last 90 days. We track these users anonymously.

What SLAs are available?

We have SLAs for the uptime of our SDK, turnaround time for P0 issues and email support responsiveness. Contact us for details.

How are automatic updates delivered?

Your extension remote loads the InboxSDK javascript implementation. As changes are made to Gmail, we automatically deploy fixes and your users just need to refresh Gmail, no extension updates required.

I don't know how many users I'll have, can I still get started?

It's fine to start with our startup plan. If you exceed 10K active users we'll reach out to discuss our enterprise plan. It's the same SDK so no need change your app in any way. Feel free to reach out at any time for more info on pricing.

What's included in the dedicated support?

Direct access to InboxSDK engineers for support issues with a 24 hour turn around time. Your bugs and feature requests are also prioritized.

Creating an extension inside of Gmail solved a significant pain for our users. Enabling Docsend functionality inside of Gmail made the user experience easier. Simply by being more available to our users, we increased average user engagement by 13% in the first week.

Making it extensible was one thing I always thought was missing from Gmail. It would be insane for app developers not to take advantage of this huge platform.
