Bulk SMS can be an effective way to inform donors about your charity’s upcoming projects and initiatives. Here are the steps to follow:

1. Collect phone numbers: First, you need to collect the phone numbers of your donors. Make sure you have their permission to contact them via SMS.
2. Choose a bulk SMS service: There are several bulk SMS services available online. Choose one that fits your needs and budget.
3. Compose your message: Keep your message brief and to the point. Include the name of your charity, the upcoming project or initiative, and how the donors can contribute.
4. Personalize your message: Address your donors by their name in the message. This will make them feel more connected to your charity.
5. Schedule your message: Choose a date and time when most of your donors are likely to be available to receive the message.
6. Send the message: Once you have composed and scheduled your message, send it to your donors.
7. Follow up: Follow up with your donors to remind them about the upcoming project or initiative. You can also send them updates about the progress of the project.
   Remember to respect your donors’ privacy and preferences. If they opt-out of receiving SMS messages, make sure you remove their phone number from your list.
