Highest immediate…
ROI in a head-to-head test against 5 other SMS rental vendors
ROAS for combined immediate and downstream revenue in the 2024 cycle
THE CHALLENGE
As a Democratic organization that regularly supports urgent and high-stakes campaigns across the country, this member of The Digital Co-Op regularly invests in a high volume of list rentals across a range of vendors to ensure it is always bringing in new and high-quality prospective donors. This organization turns to MissionSMS consistently as one of its top sources, hoping to acquire new leads that will continue to give in support of crucial races beyond the first SMS appeal.
THE STRATEGY
Winner of the 2024 Campaign Tech Award for Innovation in Texting, MissionSMS finds the mobile supporters most likely to donate to your campaign over text using the unrivaled predictive modeling power of The Digital Co-Op, helping you add high-quality donors to your digital program.
Here’s how this major Democratic organization leveraged MissionSMS to drive both immediate and long-term ROAS for its organization:
Establishing a steady monthly cadence for investment. While the monthly budget is determined by results, this organization allocates consistent funds toward MissionSMS as one of its top three vendors for SMS list growth investment, so it is always fueling its lists with the strongest new mobile leads.
Targeting models by geographic location. As major moments in a campaign cycle unfold, this organization focuses its list growth investment on closely targeted locations, building fundraising appeals with relevant local surrogate signers.
Scaling up in key moments. Ahead of major moments of response for the Democratic party – the DNC, debates, Trump’s addresses – this organization scales up investments, making sure to geo target by time zones to achieve immediacy while meeting regulations.
Leaning on MissionSMS for content testing. To mitigate the higher costs of SMS, this organization tests its top-performing broadcast message through MissionSMS first to a small pool, before determining whether there’s an ability to scale across other vendors.
THE RESULTS 
For one of the organization’s largest 2025 SMS campaigns, head-to-head testing versus five other SMS rental vendors showed MissionSMS driving the highest immediate ROI:
What’s more, in the 2024 cycle, MissionSMS drove the highest ROAS for combined immediate and downstream revenue. Donors acquired through MissionSMS and making their first gift over text are giving not just on the first text, but again and again.
