Perplexity

Send emails in failure-proof workflows with Mastra AI

Build multi-step processes that require sending email. You can use `send_email` or `send_template_email`, knowing the framework handles retries automatically if the initial send fails. This is critical when your workflow depends on immediate delivery. The agent's built-in backoff logic means it doesn't just fail; it waits and tries again with increasing intervals until the email sends successfully.

Audit message history using Mastra AI

When a complex workflow runs, you need proof of what happened. Use `list_logs` to get an overview of all recent activity, and then use `get_log_details` for specific investigation. This keeps your backend reliable. The system ensures that even if the main process fails due to external factors, you can still check every step's log history right within the agent framework.

Maintain recipient lists with MCP Server

Before triggering an expensive workflow, your agent checks compliance. It uses `list_suppression_list` to make sure you aren't accidentally emailing a blocked address. You also verify sending capabilities by calling `list_domains`. These checks are mandatory for any mission-critical backend process that needs guaranteed deliverability.

Setup guide

Set up Zoho ZeptoMail MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Zoho ZeptoMail tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "zoho-zeptomail-mcp-client",
  servers: {
    "zoho-zeptomail-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Zoho ZeptoMail Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Zoho ZeptoMail tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Zoho ZeptoMail transactions"
);
console.log(result.text);
