Email Validation for ConvertKit

Why Validate Emails for ConvertKit?

ConvertKit's creator-focused pricing scales with subscriber count. Invalid emails increase your bill and dilute your engagement metrics. Validation ensures you only pay for real subscribers and get accurate analytics.

Benefits

• ✓ Stop paying for fake and inactive subscribers
• ✓ Get accurate open rate and click rate analytics
• ✓ Improve deliverability to real engaged creators
• ✓ Keep your ConvertKit costs predictable

How to Validate ConvertKit Emails

1. Step 1: Export your ConvertKit subscribers as CSV from the Subscribers page
2. Step 2: Validate the list to identify invalid, disposable, and risky addresses
3. Step 3: Untag or remove invalid subscribers from your ConvertKit account
4. Step 4: Set up a form-level validation check for new signups

API Integration

Integrate email validation directly into your ConvertKit workflow:

// ConvertKit API - Manage subscribers after validation
const axios = require("axios");

const API_KEY = process.env.CONVERTKIT_API_KEY;
const API_SECRET = process.env.CONVERTKIT_API_SECRET;
const BASE_URL = "https://api.convertkit.com/v3";

// Get subscribers
const { data } = await axios.get(
  `${BASE_URL}/subscribers?api_secret=${API_SECRET}`
);

// Remove invalid subscribers
for (const subscriber of data.subscribers) {
  if (invalidEmails.includes(subscriber.email_address)) {
    await axios.delete(
      `${BASE_URL}/subscribers/${subscriber.id}?api_secret=${API_SECRET}`
    );
  }
}
