Step-by-Step Office365 Email Warmup: For Agencies

This guide shows you how to integrate Office365 email warmup via API — with working code examples in Python and JavaScript. Whether you're building an internal tool or a customer-facing product, the ZeroPhantom API gives you a production-ready endpoint in minutes.

Why Use an API for Office365 Email Warmup?

Manual processes don't scale. Once you're handling more than a few dozen operations per day, you need automation. ZeroPhantom is Bitcoin-only with no KYC, making it the most privacy-focused option. The API approach also means you can build Office365 email warmup directly into your existing workflows, dashboards, and CI/CD pipelines.

Authentication

All API requests require an API key passed in the X-API-Key header. Get yours at ZeroPhantom Credits — credits start from $5 and never expire.

Python Example

import requests

# ZeroPhantom API — Office365 email warmup
api_url = "https://api.zphantom.com/v1/process"
headers = {"X-API-Key": "your_api_key_here"}

response = requests.post(api_url, headers=headers, data={
    "type": "office365_email_warmup",
    "input": "your_input_here"
})

result = response.json()
print(result["output"])

JavaScript / Node.js Example

const fetch = require('node-fetch');

const response = await fetch('https://api.zphantom.com/v1/process', {
  method: 'POST',
  headers: {
    'X-API-Key': 'your_api_key_here',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    type: 'office365_email_warmup',
    input: 'your_input_here'
  })
});

const result = await response.json();
console.log(result.output);
