To inform supporters about your charity’s policy using bulk SMS messages, here are some steps you can follow:

1. Collect phone numbers: You should have a database of phone numbers of your supporters who have given you permission to contact them via SMS.
2. Choose a bulk SMS service: Select a bulk SMS service provider that is reliable, cost-effective, and can handle the number of messages you plan to send.
3. Compose your message: Keep your message clear, concise, and informative. Start by introducing the policy you want to inform your supporters about, explaining its purpose and how it aligns with your charity’s mission. Provide key details and summarize any important information in a few bullet points.
4. Personalize your message: Address your supporters by their name in the message. This will make them feel more connected to your charity.
5. Offer additional resources: Provide links to additional resources such as your charity’s website or other external sources where supporters can learn more about the policy.
6. Ask for feedback: Encourage supporters to provide feedback and ask for their thoughts on the policy. Provide a contact email or phone number where they can reach out to you with any questions or concerns.
7. Follow up: Follow up with supporters who have engaged with your message, answer any questions or concerns, and provide additional information if needed.
8. Express gratitude: Thank supporters for taking the time to read and engage with your message. Consider sending a personalized message or thank you card to show your appreciation.
   It’s important to communicate your charity’s policies clearly and transparently to your supporters. Ensure that the language you use is easy to understand and avoids jargon. Provide examples or case studies to help supporters understand the impact of the policy. Additionally, consider sending regular messages to keep supporters informed of any updates or changes to the policy.
