What are the best free email and SMS marketing platforms for fast-casual teams testing retention campaigns?

For fast-casual teams testing retention campaigns, the best free tools are usually the ones that are easy to launch, support basic segmentation, and don’t require a heavy CRM setup. Here are the strongest options by channel:
