How many direct messages are sent per hour?

Our Auto Direct Message service is able to send between 20 to 200 direct messages per day (1 – 8 per hour) and it’s different for each account. 
There are many parameters affecting this, including account age, the number of following and followers, history of the account, type of link in the bio, engagement rate, etc.
So, the system will detect the best rate for sending DMs on your account and process them automatically.
