OpenAI Integration

Learn how WarmOpener integrates with OpenAI's powerful language models to generate hyper-personalized email content at scale.

What is OpenAI Integration?

WarmOpener uses OpenAI's latest GPT models (GPT-4o, GPT-4o Mini, and GPT-5.2) to generate personalized content for each contact based on their profile data. This allows you to create unique, relevant emails without manually writing each one.

How It Works

  1. You provide a prompt: Tell the AI what kind of content to generate (e.g., "Write a personalized opening line")
  2. WarmOpener adds context: Combines your prompt with contact data (name, company, industry, etc.)
  3. OpenAI generates content: GPT model creates unique text for each contact
  4. Content stored: Generated text saved as a custom field on the contact
  5. Use in emails: Insert generated content using placeholders like {{Generated_Field}}

Why Use AI Personalization?

Speed: Generate content for 1,000 contacts in 10-15 minutes vs. days of manual work

Quality: AI can analyze contact data and create relevant, context-aware content

Scale: Personalize at scale without sacrificing quality or hiring more SDRs

Consistency: Maintain brand voice while still being personal to each recipient

Pricing

You pay OpenAI directly for API usage. WarmOpener doesn't mark up or charge extra for AI features.

Typical costs:

  • GPT-4o Mini: ~$0.0008 per contact = $0.80 for 1,000 contacts
  • GPT-4o: ~$0.003 per contact = $3 for 1,000 contacts (Recommended)
  • GPT-5.2: ~$0.015 per contact = $15 for 1,000 contacts

Note: Exact costs depend on prompt length and generated content length. OpenAI charges per token (roughly 4 characters = 1 token).

💡 Pro Tip

Start with GPT-4o (recommended) for the best balance of quality and cost. It's proven for cold email personalization with tight, human-sounding output. Use GPT-4o Mini for high-volume campaigns where budget matters most, or GPT-5.2 when you need cutting-edge quality.
