Explanation
Google Hard-Cap Limitations
Please see Gmail sending limits in Google Workspace - Google Workspace Admin Help.
Soft Limitations
Google can and does suspend accounts if they are deemed too "spammy" or otherwise suspicious. This can result in a restriction or suspension occurring before those hard-cap limits are reached. Repeated offenses will be escalated, if this happens you may be placed on the blocked senders list. To attempt to remove yourself from this list, submit a ticket to 4Help.
