The free Sendmux plan is tight: 2 mailboxes, a $1 usage credit, a Sendmux footer on outgoing email and managed sending of 2 per hour. Postpaid usage is Enterprise only, and unlimited resources on Pro are subject to fair usage and approval.
Zapier and Make are no-code workflow tools, so they move email between apps rather than act as a mailbox layer for agents. Zapier connects 9,000+ apps and has AI agents, chatbots and forms; it has a free tier, and Professional is $19.99 per month for 750 tasks. Make builds visual workflows and AI agents; Core is $9 per month (price shown for 10k credits a month) with a free tier. Both can send mail through connected accounts, but neither offers Sendmux's MCP endpoint in our data.
