How frequently does HyperSend check for new deliveries?
On HyperSend.com, the polling time for the auto-download feature, found on Options, Account Settings, is 30 minutes. What this means is HyperSend will check with the HyperSend server every thirty minutes to see if your account has received any new deliveries. If there are some, it will begin downloading them to your local inbox without requiring you to visit the Pick up page.
