With a marketing automation platform, you can create a workflow that will automatically call a prospect at a pre-determined or fixed time after they fill out an initial information form.
With a signup form, you can gather the phone numbers of interested parties. Remember to make it clear to them during this process that they are opting in to receive communications from you.
Using a delay, you can set a custom waiting period before a person who filled out the form will be contacted. You can choose to contact them either after a fixed time after they submitted the form, such as an hour or a week, or at a custom time.
After the delay period is over, the platform will automatically make the phone call. This is an excellent way of reaching out to people in different time zones, because it is not contingent on your schedule or availability to send the communication.
