Resend
Your AI agent sends emails through Resend the moment a customer interaction requires it. Order confirmations, password resets, appointment reminders, and follow-ups happen automatically within the conversation flow. No manual triggers, no delayed notifications.
Your AI agent leverages Resend's email API to send, schedule, cancel, and track messages while managing contacts, audiences, and domains programmatically.
Resend
Real-world scenarios where your AI agent uses Resend to send the right email at the right moment, triggered entirely by customer conversations.
A customer books an appointment through your AI agent on WhatsApp. The agent immediately sends a confirmation email via Resend with the date, time, and location details in a branded HTML template. The customer receives both the chat confirmation and an email receipt within seconds. Your team never touches a send button.
A website visitor asks about your product and wants updates. Your AI Agent captures their email and name, creates a new contact in the appropriate Resend audience, and confirms the subscription. The next time you send a product newsletter, this contact is already on the list. Lead capture happens naturally, without forms.
A customer reports an issue that needs investigation. Your AI Agent schedules a follow-up email via Resend for the next business day, including the conversation summary and case reference. If the issue resolves sooner, the agent cancels the scheduled email. Customers feel cared for, and your follow-up process runs on autopilot.

FAQs
The agent calls Resend's Send Email API with the recipient, sender address, subject line, and HTML or plain text body. It supports CC, BCC, reply-to addresses, and custom headers. The email is sent from your verified domain, maintaining your brand identity.
Yes. When sending an email, the agent passes a scheduled_at parameter in ISO 8601 format. The email queues in Resend and delivers at the specified time. The agent can also update the schedule or cancel the email entirely before it sends.
Tars needs a Resend API key with permissions to send emails, manage domains, and manage audiences and contacts. Generate this key from your Resend dashboard under API Keys. You control the scope and can create a key specifically for the Tars integration.
No. Email content is composed and sent in real time through Resend's API. Recipient addresses, message bodies, and audience data are not stored by Tars. All email records remain in your Resend dashboard where you have full visibility and control.
Yes. The agent can create, retrieve, and delete contacts within any audience in your Resend account. It uses the audience ID to target the correct list, so contacts get added to the right segment based on conversation context.
Marketing automation tools send emails based on predefined triggers and schedules. Tars sends emails based on live conversation context. The AI agent decides when an email is needed based on what the customer says, not a static workflow. This makes transactional messaging reactive and personal.
The agent can trigger domain verification through Resend's Verify Domain endpoint. If verification fails, the agent informs you of the issue and suggests checking your DNS records. Emails cannot be sent from unverified domains, matching Resend's standard security policy.
Only scheduled emails that have not yet been delivered can be canceled. The agent uses Resend's Cancel Email endpoint with the email ID. Once an email has been delivered, cancellation is not possible. The agent communicates this clearly if a cancellation attempt comes too late.
Don't limit your AI Agent to basic conversations. Watch how to configure and add powerful tools making your agent smarter and more functional.
