What is a good email scheduling tool for Outlook?

I need an email scheduling tool for my business that allows me to send emails at a specific date and time in future.

Can you answer this question?

Answer

Under Delivery options, select the Do not deliver before check box, and then click the delivery date and time that you want

Outlook comes with a schedule delivery feature built right in.

In the message, on the Options tab, in the More Options group, click Delay Delivery.
Click Message Options.
Under Delivery options, select the Do not deliver before check box, and then click the delivery date and time that you want.

After you click Send, the message remains in the Outbox folder until the delivery time.
