Yes. You can send messages based on a range of sign up dates (Date Added dates) by using the filter under Advanced on the Message Sending page. Tick the Advanced box on the Send Message page to reveal the Advanced sending options. Under Date Added, enter the range of dates you wish to target in the field for Beginning and Ending Dates.
Remember if you’ve used other filters, such as Categories or the State/province and Country filter, as well as the Date Added filter, your email will only be sent to the emails that fit the parameters of the other filters AND were added between the dates you specify.
