Redtail Speak offers a compliant way for you to text message your clients and collaborate with your staff in real-time. With texting now an everyday part of every generation’s lives, incorporating a texting solution into your practice as a financial advisor allows you to solidify your client relationships through more effective engagement and improved communications. Redtail Speak is available as a standalone texting/chat solution, while offering integration with Redtail CRM for those who subscribe to both solutions. Using Speak, every text conversation is fully searchable and automatically archived, recorded daily, and sharable with email surveillance providers, offering you a safe, compliance-approved way to communicate with your clients.
