Send and manage transactional email with Resend, straight from a phone call.

Resend MCP lets your AgentCalls agent send and manage transactional email while it talks to a customer. After a call, your agent can send a booking confirmation, a receipt, or a follow-up with the details the caller just agreed to. It can also check whether an email was delivered, so you know the customer received what they were promised. Connect your Resend account from the tool's settings and your agent can use it on every call, in English or Arabic.
