Encouraging donors to become monthly givers through bulk SMS messages can be an effective way to sustain your charity’s operations. Here are some steps to follow:

1. Collect phone numbers: You should have a database of phone numbers of your donors and 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 explaining the importance of monthly giving and how it can help sustain your charity’s operations. Provide examples of how regular donations can make a difference and encourage donors to consider making a monthly gift.
4. Personalize your message: Address your donors by their name in the message. This will make them feel more connected to your charity.
5. Offer incentives: Consider offering incentives for donors who sign up to become monthly givers, such as exclusive content or early access to events.
6. Provide easy sign-up options: Include a link or instructions for donors to easily sign up to become monthly givers. Make the process as simple and straightforward as possible.
7. Follow up: Follow up with donors who have expressed interest in becoming monthly givers but have not yet signed up. Send a reminder message and provide additional information about the impact of monthly giving.
8. Express gratitude: Thank donors who have become monthly givers for their support and express how their contribution is making a difference. Consider sending a personalized message or thank you card to show your appreciation.
   It’s important to ensure that your donors feel comfortable and confident about their monthly gifts. Provide transparency on how their donations are being used to support your charity’s operations, and provide regular updates on the impact of their contributions. Additionally, consider sending regular messages to your monthly donors, sharing stories of impact, and keeping them engaged in your charity’s work.
