GMass is a cold email sequencer for teams that bring their own inboxes. It scores 39 in the index and sits 34th of 35 cold email tools, with plans from $29.95 a month. Its buying terms are clean: public prices, monthly billing and a way to try before paying in full. Deliverability is its weakest group at 7/40. Its own site says it doesn't offer ongoing warm-up in the price, inboxes for sale or automatic SPF/DKIM/DMARC, and that is the usual reason to look at GMass alternatives.

Inbox providers that confirm a built-in sequencer and ongoing warm-up in the inbox price, so inboxes and sending sit on one bill. Ordered by score.
Start with what you already own. If you have warmed inboxes and only want a different sender, compare entry plans: SmartReach.io starts at $29, PlusVibe at $37, Smartlead and Woodpecker at $39. If you would rather buy inboxes and run campaigns in one account, every tool on this list sells inboxes inside the tool and includes ongoing warm-up in the price, which GMass doesn't offer. For agency work, all eight confirm client workspaces or white-label; GMass doesn't state it. If an AI agent will drive your campaigns, SmartReach.io is the one that doesn't state an official MCP server. Instantly is the only tool here that confirms dedicated IPs, replacement of burned inboxes and pre-warmed inboxes together. The index doesn't measure inbox placement in practice, so test before you scale.
