Once you've received written or verbal permission, there are a few different ways you can add contacts (subscribers) to your account. Here are the most common:
Sync your lists from a Church Management Software (CHMS): If your church uses Planning Center, Rock RMS, Church Community Builder, or Breeze, you can easily sync your existing lists into Clearstream. As you make changes to your lists in your CHMS, they'll automatically stay up-to-date in Clearstream as well, so no need to maintain two databases.
Import via CSV/Excel file: If you already have a file of contacts, you can easily import those numbers into your Clearstream account and add them to a list. Learn how to format your file and where to import here.
Manually add people: Likely not an ideal option if you have hundreds of people to add, but a great choice for adding a few subscribers at a time. To add manually, just head to Subscribers > Add Subscribers > Add Manually.
There are also a couple of ways people can add themselves which requires almost no action on your end:
Encourage your people to text a keyword: One of the easiest ways to add contacts is to create a keyword that people can text to opt in (i.e. text JOIN to 775-347-7333). They can be automatically added to your texting list, receive a digital connect card, and much more.
Create a signup form: Signup forms allow people to fill out their contact info and even choose which Clearstream lists they'd like to join. They can be embedded on your website or shared as a link.
