Mailyond alternatives

Mailyond reads and replies to email across multiple domains from one inbox, and sends app email through an API. It also offers a hosted MCP server so an AI assistant can read and answer replies. When choosing a replacement, weigh whether you need per-domain replies from one inbox, agent-owned mailboxes, or outbound sales outreach. Each alternative below covers a different one of these needs.
