About

Ballast is a cold email platform for teams running one-to-one outbound campaigns from their own mailboxes. Users can connect Google Workspace, Gmail, Microsoft 365, or other SMTP/IMAP accounts; import leads; build multistep sequences with personalization and variants; and manage replies in a shared inbox. The platform includes mailbox warmup, sending schedules, domain checks, inbox-placement tests, bounce thresholds that can pause sending, and campaign analytics. Plans are priced by monthly email volume and include unlimited mailboxes and seats, API access, webhooks, and MCP tools. Teams can connect AI models for reply classification and drafting, configure Slack reply alerts, or automate workflows through n8n. CSV presets support lead imports from Apollo, Clay, Instantly, Smartlead, and Lemlist.

About

Marvenn Outbound is a web-based AI cold-email platform for B2B startups, agencies, and founder-led sales teams. It identifies prospects for selected audiences, researches them, and drafts personalized first emails based on real prospect details. Users review and approve sample emails before campaigns begin; after approval, campaigns run automatically from pre-warmed mailboxes managed by the platform. The service lets teams set daily sending budgets and adjust them as campaigns perform. It grades incoming replies to surface interested prospects, sends booking links to warm replies, and places meetings on the calendar. By handling prospect sourcing, email preparation, mailbox warmup, sending, and reply triage in one workflow, Marvenn Outbound helps lean sales teams manage cold-email outreach without building lists or warming inboxes themselves.
