How many total invitations can an admin send out to users at once?

The correct answer indicates that an admin can send out a total of 2000 invitations to users at once. This limit is set to ensure that the process of onboarding new users remains manageable and efficient. It also helps maintain the performance and stability of the platform by preventing overwhelming server requests. Knowing this limit is crucial for administrators as they plan their user onboarding strategies and campaigns, ensuring they stay within the defined parameters to avoid errors or failures in the invitation process.

The other options suggest different quantities, but they either exceed or do not meet the established maximum for concurrent invitations that can be sent. Understanding these specific limits is vital for effective organizational management within the DocuSign environment.
