How does pricing compare?

Mailchimp: Freemium. Freemium with a free tier for smaller lists, plus paid Essentials, Standard, and Premium plans billed by contact count. A free trial of paid plans is offered, with annual billing discounts. Runopt: Contact for Pricing. Runopt does not publish public pricing. The site invites visitors to join a waitlist and to contact the team, and it describes a tiered set of packages (with some use cases, such as rail and agriculture, planned for later packages). Pricing is therefore arranged directly with the vendor.
