Definition
Choosing the right email service provider is one of the most important decisions an email marketing program makes. The wrong choice limits your ability to scale, adds unnecessary cost, or forces a painful migration later. A structured evaluation process prevents these problems.
Evaluation Criteria
- Deliverability: What is the ESP's sender reputation? Do they have dedicated IP options? What authentication support do they offer?
- Scalability: Can they handle your peak sending volume? Is there automatic IP warming for growth?
- Features: Automation, segmentation, A/B testing, dynamic content, API capabilities
- Integrations: Native connections to your CRM, ecommerce platform, and analytics tools
- Pricing: Per-subscriber or per-send? What are overage costs? Are there setup or migration fees?
- Support: What is the support SLA? Is there dedicated account management at your tier?
- Migration ease: Is there a migration team or documented process for importing lists and templates?
Recommendation
Trial 2-3 ESPs with a test list before committing. Deliverability performance varies significantly between providers for different industries and sending patterns.
