Selecting the right platform is more than checking features. Here’s your action-oriented checklist for making a decision aligned with ROI:
- Define your goals & KPIs: e.g., reduce cost per lead by X%, improve customer lifetime value by Y%, shorten sales cycle by z.
- Assess integration needs: Do you need CRM, CDP, or data warehouse connections? If yes, enterprise tools like Salesforce or Marketo may serve you best.
- Evaluate team readiness & ease of use: Will your team adopt a complex platform or prefer something that works out of the box?
- Budget & scalability: Ensure you compare the total cost of ownership and consider growth over 12-24 months.
- Vendor support & ROI proof: Ask potential vendors for case studies or ROI benchmarks that align with your industry and size.
- Start with high-impact workflows: Don’t aim to automate everything at once. Start with core journeys (e.g., welcome, cart abandonment, lead nurture) and measure.
- Compare your scenarios:
If your team prioritizes email-driven automation with high ROI, start with Klaviyo or ActiveCampaign.
If enterprise integration and predictive AI are priorities, Salesforce or Adobe Marketo delivers superior analytics and scalability.
