10  Example: Email Campaign Optimization

10.1 Discovery Meeting Transcript

Below is the transcript of a meeting between data scientist Sarah Chen and various business stakeholders. Sarah’s contributions to the conversation are high-lighted.

Participants:

  • Sarah Chen (Data Scientist)
  • Michael Roberts (Chief Marketing Officer)
  • Jennifer Hayes (Director of Marketing)
  • David Kim (Marketing Manager)

Sarah: Thank you all for meeting today. I’d like to understand the business context and specific challenges around your email campaigns to ensure our data science project delivers meaningful value. Could you start by describing the current situation?

Michael (CMO): Our email marketing costs are eating up too much of our budget. We are paying per email sent through our vendor, ExactTarget, but our response rates are low. We need to be more strategic about who we are targeting and when.

Sarah: Could you help me quantify the current situation? What are your current response rates and costs?

David (Marketing Manager): Our average open rate is around 15%, and click-through rates hover around 2%. We’re paying $0.008 per email sent, and we are sending about 500,000 emails per month across all campaigns. That’s $4,000 monthly just in email costs.

Sarah: What defines a successful email campaign for your team? What are your key performance indicators?

Jennifer (Director): Ultimate success is conversion to sale, but we also track open rates, click-through rates, and unsubscribe rates. We have different goals for different campaign types—promotional campaigns aim for immediate sales, while nurture campaigns focus on engagement metrics.

Sarah: Could you break down the different types of campaigns you run and their specific goals?

Jennifer: We have three main types:

  1. Promotional campaigns for sales and special offers
  2. Nurture campaigns for leads who’ve shown interest
  3. Newsletter campaigns for general audience engagement

Sarah: What are your target improvement goals? What would success look like for this project?

Michael: We would like to reduce our monthly email spend by 30% while maintaining or improving our current revenue from email campaigns. That means we need to be much more precise about who we target.

Sarah: Are there any constraints or requirements I should be aware of? For example, regulatory requirements or technical limitations?

David: We need to comply with GDPR and CAN-SPAM Act. Also, our ESP (ExactTarget) has some technical limitations on segmentation and personalization. We can only use the fields available in their system.

Sarah: What data do you currently have available about your customers and their email interactions?

David: We have:

  • Customer demographics and purchase history
  • Email interaction data (opens, clicks, unsubscribes)
  • Website behavior for logged-in users
  • Campaign history and performance metrics
  • Customer service interaction records

Sarah: Are there any specific time constraints or deadlines for this project?

Michael: We are approaching our busy season in Q4. We would like to have a solution implemented by the end of Q3 to maximize impact during the holiday season.

Sarah: What is currently working well in your email campaigns that we should make sure to preserve?

Jennifer: Our segmented promotional campaigns perform better than broad campaigns. When we target based on previous purchase behavior, we see about double the conversion rate.

Sarah: Are there any past attempts at solving this problem that I should know about?

David: We tried basic RFM (Recency, Frequency, Monetary) segmentation last year. It helped somewhat but wasn’t sophisticated enough to give us the precision we need.

Sarah: Who are the key stakeholders for this project, and how should we keep them informed?

Michael: The marketing team here, plus our CFO will want to see the cost implications. Our technical team will need to be involved for implementation. Monthly updates to this group should work, with ad-hoc updates for significant findings.

Sarah: Let me summarize the key points to ensure I’ve understood correctly:

  • Primary goal: 30% reduction in email costs while maintaining revenue
  • Current spend: $4,000/month on 500,000 emails
  • Current performance: 15% open rate, 2% CTR
  • Key constraints: GDPR compliance, ESP technical limitations
  • Timeline: Solution needed by end of Q3
  • Success metrics: Cost reduction and maintained revenue
  • Available data: Customer demographics, email interactions, purchase history, website behavior

Is there anything I’ve missed or misunderstood?

Jennifer: That’s accurate. One additional point is that we would like to understand which customer segments are most valuable for different types of campaigns. This could help us with content strategy as well as targeting.

Sarah: Thank you, that is helpful. Last question: What risks should we be aware of?

Michael: Our biggest concern is maintaining revenue while reducing email volume. We can’t afford to cut off communication with valuable customers. Also, our email vendor contract renews in Q4, so any insights could help with negotiations.

Sarah: Thank you all for your time. I will document these requirements and come back with a project plan that addresses these goals and constraints. Would you like to schedule a follow-up meeting to review the project plan?

Michael: Yes, please. Set something up for next week. And make sure to include any additional data requirements you identify—we want to make sure you have everything you need to succeed.

10.2 Business Understanding Document

Overview of Strategic Alignment

The Email Campaign Optimization initiative directly addresses critical business challenges in marketing efficiency and cost management. The primary business challenge is the high cost of email marketing campaigns relative to their performance, with current spending at $4,000 monthly for 500,000 emails. The organization seeks to optimize email marketing expenditure while maintaining revenue generation, specifically targeting a 30% reduction in email costs.

Key strategic elements include:

  • Cost optimization without sacrificing revenue generation
  • Enhanced targeting precision for email campaigns
  • Improved campaign effectiveness through data-driven segmentation
  • Strategic timing for implementation before Q4 busy season
  • Vendor contract negotiation leverage through performance insights

The project aligns with organizational capabilities through existing data infrastructure and marketing automation tools (ExactTarget), though technical limitations in segmentation and personalization have been identified as constraints.
