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

Maildoso provides outbound mailboxes built for cold email, combining SMTP and Google Workspace infrastructure, fast setup, strong deliverability, and automated technical configuration. It helps teams diversify their sending strategy with reputable mailboxes built specifically for cold outreach, so campaigns are not dependent on one sender type, domain, or provider. Users can register domains directly in the dashboard or connect their own, enter mailbox names, and have SPF, DKIM, and DMARC auto-configured so mailboxes are ready to export and use with outreach platforms in minutes. Maildoso supports SMTP mailboxes, Google Workspace mailboxes, and combined setups, giving teams flexibility based on their sending strategy and target audience. It connects with popular sequencers and outreach tools such as Instantly, Smartlead, Saleshandy, and others, making it easier to move newly created mailboxes into active campaigns.
