Expanding the Gmail delegate limit

What’s changing 

We’re expanding the number of allowed Gmail delegates from 25. In addition, to help with delegate management, delegation for Contacts is now available via the Contacts API

Who’s impacted 

Admins, end users, and developers 

Why you’d use it 

We’ve heard from you that allowing more than 25 users to access a single mailbox can sometimes help manage the messages. For example, in certain cases, the volume and variety of inquiries necessitated having a larger group of individual users be able to read and respond to them. To address this need, we‘ve enabled higher limits. 

Additionally, we’re now offering programmatic access to managing Contacts delegation, similar to how Gmail delegation can be managed via the API. Note that delegation limits for Contacts delegation are not changing. 

Additional details 

Where previously we advised that a technical limit of 25 delegates applied for email delegation, our updated guidance is as follows: 
  • With typical usage, up to 40 of those configured users may concurrently access the account. However, please note that 
    • All other Gmail limits and policies continue to apply. 
    • Heavy usage by any user will reduce the overall concurrency limit. This will most commonly occur if automation or scripting (e.g. via Chrome extension or API) is used to engage with the mailbox via high frequency actions. 
  • Up to 1000 delegates may be configured as delegates for the purposes of setting up access control. 
  • For high-volume operations such as sales or support teams, we continue to recommend the use of a dedicated ticketing system. Gmail is not intended to replace a ticketing system for scaled operations. 
  • Contacts delegation is still limited to 25 delegates per user.
