Adjusting the contact limits for your clients need to be done prior to sending a campaign and it is up to you to adjust the limit for your sub-accounts as you see fit. As the account reaches its sending limit, a notification will appear at 75%, 90% and 100% usage. Until the limit is adjusted appropriately, mailings will not be sent.
To increase the sending limits for one of your clients, hover over your client’s name under the Clients tab and click on Edit Contact Limit.
Note: A contact cannot have a limit of “0”.
