The right message to the right slice beats the same message to everyone. Segmentation is just sending people what's actually relevant to them, mail voters get ballot reminders, in-person voters get polling-place info, people who already voted get thanked, not nagged. It lifts response and cuts wasted (and annoying) sends.
Segments that earn their keep
Vote method (so mail voters and Election Day voters get different reminders), turnout propensity, geography and time zone, and relationship type (donor, volunteer, supporter). Each one lets you say something true and useful to that group instead of something generic to all.
Suppress, don't just target
The most valuable segment is often the one you don't send to, people who already voted, people who opted out, people outside the district. Suppressing them saves money, protects your reputation, and keeps you from the annoyance that drives STOPs.
Frequently asked questions
How should I segment a campaign texting list?
By what changes the message: vote method, turnout history, geography/time zone, and relationship type (donor, volunteer, supporter), plus suppressing people who already acted or opted out.
Does segmenting a texting list actually help?
Yes, relevant messages to smaller segments lift response and cut cost versus one generic blast. Suppressing already-voted and opted-out contacts protects reputation too.
