Quotas and limits in Yandex Cloud Postbox

Written by
Yandex Cloud
Updated at February 11, 2026

Yandex Cloud Postbox has the following limitations:

  • Quotas are organizational constraints that can be changed by support on request.
  • Limits are technical constraints of the Yandex Cloud architecture. You cannot change the limits.

If you need more resources, you can increase your quotas in one of the following ways:

  • Make a request to increase your quotas.
  • Contact support and specify which quotas you want increased and by how much.

To have your request processed, you must have the quota-manager.requestOperator role or higher, e.g., editor or admin.

You can manage your quotas with Cloud Quota Manager.
