Mailcoach vs Email Spam Tester

Mailcoach is an email marketing platform built for growing creators, developers, and businesses. It covers campaigns with segmentation, split testing and analytics, no-code automations with triggers and actions, and transactional email with an API. Pricing is pay-per-email-sent with unlimited contacts, lists and automations, so the bill follows send volume instead of list size. Teams can send through Mailcoach's managed delivery, bring their own provider, or self-host the application.

Send your issue to a test address and see where it landed at twelve mailbox providers, inbox or spam. The same report runs 42 technical checks on the copy that arrived: SPF, DKIM and DMARC alignment, blocklists, two spam engines, the Gmail and Yahoo bulk sender rules, and the content itself. Every problem comes with a plain-language fix. Free, no signup, with an API and an MCP server if you want to test from a script or an AI agent.
