Description

From the marketplace listing

Compare newsletter platforms, mailing list services and email marketing costs using MailerChoice's curated pricing catalog. Find forever-free plans and compare their subscriber and sending limits. Estimate costs for your list size, sending frequency and expected growth, including a newsletter sent only four times a month. Find individual plans with all your required features, such as automations, landing pages, segmentation, SMS or API access. Results include modeled USD costs, plan restrictions, official informational pricing links and the catalog's source date. No MailerChoice account or sign-in is required. MailerChoice is a research tool. It does not send newsletters, manage subscribers, create provider accounts, sell subscriptions or process purchases. The catalog is not exhaustive or a live quote. Monthly sending estimates do not verify daily caps, service quality, deliverability or specific integrations. Check provider pricing and plan restrictions before making a decision.

Initial directory submission. Four public read-only MCP tools provide free-tier discovery, same-plan feature matching, feature lookup and modeled pricing comparisons. Every tool explicitly declares readOnlyHint=true, destructiveHint=false, openWorldHint=false and idempotentHint=true, with input/output schemas and structured results. No authentication or reviewer credentials are needed.
