Twilio and TextIt offer a solution to create reliable and resilient communications over SMS, voice, and WhatsApp for digital engagement. The solution involves setting up a communication platform using Twilio Programmable SMS and TextIt's campaign management software to engage with people in 2-way communication. A sample program is provided to send expectant mothers a broadcast message to enroll them in a prenatal program and periodic reminders to ensure healthy pregnancy, using a registration flow that sends messages to all contacts, validates the DueDate, and enrolls them in the program. The solution requires obtaining opt-in consent from participants, uploading a participant list, creating a 2-way registration flow, connecting the flow to Twilio SMS, testing the flow, scheduling reminders for the campaign, and troubleshooting tips. Pricing is flexible pay-as-you-go with no contracts, and discounts are available for social impact organizations.
