Transfer Contact Lists into Ascent360

Please follow the below guide to transfer contact lists into the Ascent360 Platform. For security purposes, please do not email files with Personally Identifiable Information (PII) to any Ascent360 team member.

Export contacts from your previous Email Platform

  1. Identify the contact list(s) you want to have transferred to Ascent360.
    • Most clients transfer no more than five lists: a large general newsletter list and a handful of separate lists, if applicable.
    • We recommend using this opportunity to de-clutter your contact lists by transferring only lists that have been sent to within the past year.
  2. Export contacts to .csv or .xlsx files. 
    • At minimum, each file should include First Name, Email Address, and Email Permission. Last Name and Individual Creation Date is highly recommended as well. Other customer information, such as phone or postal information, can be imported at request.
    • Email permission is sometimes phrased as subscription status = Yes/No
  3. Export your unsubscribed list. 
    • All users who are suppressed and/or are opted-out from receiving messaging (Email permission = No)
