When evaluating a mass email platform, consider the following: * **Scalability:** Can the service handle your growth from 1,000 to 100,000 subscribers? * **Integrations:** Does it sync bi-directionally with your ecommerce store or CRM? * **Analytics:** Does it provide [detailed reporting](https://mailchimp.com/help/about-email-campaign-reports/) on revenue attribution, not just open rates? ## Conclusion A robust bulk email service remains the backbone of digital customer retention.
