4. Include a call to action: Encourage your audience to take action by including a clear call to action, such as “Donate now to double your impact” or “Make a donation to support our mission and have it matched.”
5. Use catchy language: Use a catchy and attention-grabbing language that entices your audience to donate. Consider using emoticons, puns, or humor to make your message stand out.
6. Provide a value proposition: Give your audience a reason to donate. Highlight the impact of their donations and how they can double their impact by participating in the matching gift campaign.
7. Timing is key: Send your messages at a time when your audience is most likely to be receptive. Avoid sending messages during times of the day when they are likely to be busy.
8. Use a reliable SMS service provider: Choose a reliable SMS service provider to ensure that your messages are delivered promptly and efficiently.
