Mailstand
Cold email across multiple mailboxes
What is Mailstand
Mailstand connects multiple mailboxes to a single cold email campaign, automatically distributing and rotating send volume across them so no single inbox carries the full load. It's built for SDRs, founders, and agencies running outbound at volume — particularly those managing several Google Workspace accounts or client inboxes under one roof. The standout capability is agency mode, which lets operators manage multiple client campaigns and mailboxes from a single dashboard with unified statistics. A/B template testing is unlimited, and sending schedules can be set per timezone. The honest limitation: Mailstand's integration footprint is narrow — Google Workspace is the primary connection, and there's no native CRM sync, so teams needing HubSpot or Salesforce handoffs will have to wire that themselves.

Vanderbuild take
For SDRs, founders, and agencies who run cold email from multiple inboxes, Mailstand is one of the more honest tools in the Email Sender category — it does one thing (multi-mailbox cold outreach) and prices it by mailbox rather than by seat, which actually makes sense. The API is available, so you can wrap Mailstand into your own automation layer or MCP setup without too much friction — it's not a native MCP server, but capable enough that a technical team can build around it. At $12/mo to start, the risk to test is low, and the 7-day free trial means you're not committing blind. The real ceiling is integrations: if your workflow depends on syncing replies or contact status back to a CRM, you're building that bridge yourself — there's no native HubSpot or Salesforce connector here.
