Scale to Win Text allows organizations to create and manage Opt-in Audiences composed of subscribers who have consented to receive messages via a 10DLC or Toll-Free number. This functionality is key for developing and cultivating highly engaged, warm contact lists. Learn more about creating Audiences here.
Note: You will need an active 10DLC or Toll-Free registration to use this feature. Additionally, you’ll need a new 10DLC number that hasn’t texted contacts who have not opted-in previously. Read here for more information about phone number registrations.
Set up a 10DLC or Toll-Free number for opt-in texting
If you are interested in setting up a 10DLC or Toll-Free number to message a subscribed audience, please submit a ticket to our Client Support team, or book time to chat with our Registration Ops Team.
Scale to Win staff will add a new 10DLC or Toll-Free number which is strictly designated for texting contacts who have explicitly opted in to receive messages from your organization.
Note: When a subscriber opts out after receiving a message from an opt-in 10DLC or Toll-Free number, the opt-out is applied all opt-in numbers in the subaccount This means that the opt-out will carry over to any new opt-in numbers added to that audience, including Short Codes.
Using your Opt-In 10DLC or Toll-Free number in a Campaign
Once the Scale to Win team has set up an opt-in 10DLC or Toll-Free number for your opt-in audience, these numbers will be marked with a yellow Opt-In flag. This flag is visible during the Sending Numbers step of campaign creation.
If you choose the Opt-In number, we scrub your lists to include only opted-in subscribers during the Load Contacts step.
Note: The Subscribers page has been renamed Audiences. You can click on the Audiences link in your sidebar to view your opt-in audience (Subscribers), filters, and manage audience settings.
How Can This Feature Help Your Organization?
1. Higher-quality, more engaged audiences
By separating opted-in contacts into dedicated Audiences:
- You are texting people who have explicitly consented, which improves trust and engagement
- Messages go to a warm list, leading to better reply rates, click-throughs, and donations
- Campaign setup prevents accidental texting of non-opted-in contacts
Impact: Better performance and less list fatigue.
Faster list growth while you’re waiting for your Short Code
Short Codes can take weeks to provision and are expensive. With this feature:
- You can start collecting SMS opt-ins immediately, upload them to your opt-in audience and message subscribers using an opt-in 10DLC or opt-in Toll-Free number
- When you Short Code is activated, you already have a subscriber audience you can start messaging right away
- This shortens the time between “we want to text” and “we’re texting people who asked to hear from us.”
Impact: Faster campaign launches, quicker fundraising pushes, and earlier audience engagement.
3. Stronger compliance and risk reduction
This feature helps you stay compliant with carrier and legal requirements:
- Opt-in status is enforced at the number and audience level
- Opt-outs automatically apply across the entire opt-in audience—even if you add new opt-in numbers later
- Opt-in and non-opt-in audiences are kept separate, reducing accidental violations
Impact: Lower risk of carrier filtering, fines, or account issues—and more confidence for your legal and compliance teams.
4. Lower cost access to advanced SMS features
You can now use features typically associated with Short Codes—without the cost:
- Integrations with your opt-in form (via ActBlue, ActionKit or API)
- Easy opt-in management
- Automated audience growth
All of this works on a 10DLC or Toll-Free number, which is cheaper than renting a Short Code.
Impact: Enterprise-level SMS capabilities at a smaller budget.
5. Easier campaign creation and guardrails for teams
During campaign setup:
- Opt-In numbers are clearly labeled with a yellow Opt-In flag
- Only opted-in contacts can be texted when using those numbers
- This reduces human error, especially for large or distributed teams
