Create Your Account

Getting started with CampaignKit is simple:

  1. Visit app.campaignkit.cc to create your free account
  2. Complete the registration process

Your First Email Validation

CampaignKit offers multiple ways to validate your email lists:

Upload a File

The easiest way to get started is by uploading a file:

  1. From your dashboard, navigate to the validation section
  2. Upload your email list as a CSV or Excel file
  3. Wait for the validation process to complete (typically just a few minutes)
  4. Download your cleaned list with validation results

Use the API

For developers and automated workflows:

  1. Generate an API key from your Profile settings
  2. Make API requests to validate emails in real-time or bulk
  3. Integrate validation directly into your application

Looking to integrate with your email platform? Check out our integrations for Mailjet, Mailchimp, HubSpot, and WordPress.

Understanding Your Results

CampaignKit classifies every email address into one of three categories:

Valid Emails ✓

These email addresses passed all validation checks and are safe to send to. They have active mailboxes and accept email.

Invalid Emails ✗

These email addresses will bounce. They include:

  • Syntax errors
  • Non-existent domains
  • Non-existent mailboxes
  • Disposable email addresses

Recommendation: Remove these from your list immediately.

Risky Emails ⚠

These email addresses may cause issues. They include:

  • Catch-all domains (we can’t verify the specific mailbox)
  • Role-based addresses (support@, info@, etc.)
  • Previously identified spam traps

Recommendation: Use with caution or segment separately for lower-volume campaigns.

Validation Details

Each email in your results includes:

  • Score (0-10): Overall email quality score

    • 10 = Passed all checks
    • 9 = Looks good but mailbox couldn’t be verified
    • 2 = Potential spam trap or temporary email
    • 0 = Will definitely bounce
  • Classification: Valid, Invalid, or Risky

  • Validation Checks: Syntax, Domain, MX Records, Mailbox, and more

Next Steps

Now that you understand the basics, you can:

  • Set up an integration - Connect CampaignKit directly to your email platform for automatic validation
  • Check pricing - Purchase additional validation credits as needed
  • Generate API keys - Integrate validation into your own applications

CampaignKit uses a multi-layered verification process that checks syntax, domain availability, MX records, mailbox deliverability, disposable email detection, and more—all without sending a single email.
