SendSMS is a powerful tool for managing SMS communications, enabling you to send messages, track delivery, and manage contacts. Relevance AI enhances this functionality by introducing AI Agents that automate workflows and provide deeper insights into your messaging campaigns.



SendSMS provides robust SMS messaging capabilities, allowing you to manage contacts and campaigns effortlessly. With Relevance AI, you can leverage intelligent AI Agents to automate and optimize your messaging strategies.
