Bulk SMS can be an effective way to encourage your donors to leave reviews and feedback on your charity’s platforms. Here are the steps to follow:

1. Collect phone numbers: First, you need to collect the phone numbers of your donors who have made a donation recently. 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. Thank your donors for their support and encourage them to leave a review or feedback on your charity’s platforms such as your website, social media pages, or review sites.
4. Personalize your message: Address your donors by their name in the message. This will make them feel more connected to your charity.
5. Include a call-to-action: Include a call-to-action in your message, such as “Please leave a review about your experience with us” or “Share your feedback with us to help us improve.”
6. Provide details: Provide details about where they can leave a review or feedback, such as links to your website or social media pages.
7. Schedule your message: Choose a date and time when most of your donors are likely to be available to receive the message.
8. Send the message: Once you have composed and scheduled your message, send it to your donors.
9. Follow up: Follow up with donors who have left a review or feedback. Thank them for their time and input.
   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. Also, avoid sending too many messages as it may lead to donors feeling overwhelmed and opting-out.
