[See pricing](https://ballast.to/pricing) - From $19 a month - Every feature on every plan - Unlimited mailboxes and seats [Everything you see here, your AI can do too. See how](https://ballast.to/docs/mcp) The problem ## The cheap plan is never the plan you end up on. Entry plans cap your contacts. Then the Unibox, client workspaces and placement tests sit on higher tiers or cost extra. Here is an agency sending 150,000 emails a month for 5 clients. Instantly per month - Light Speed plan $358 Total $358 Smartlead per month - Unlimited Smart plan $174 - 5 client workspaces × $29 $145 Total $319 Ballast per month - Pro plan, 150,000 emails $79 - Unibox, warmup, placement tests incl. Total $79 How it works ## Cheap is the hook. Steady is the product. Everything included ## Everything you need to run cold email. Every card below is on every plan. The plan only sets how many emails you send. - ### [Mailboxes](https://ballast.to/docs/mailboxes) Google Workspace, Microsoft 365 or any SMTP host, as many as you own. - ### [Warmup](https://ballast.to/warmup) New mailboxes trade a few emails a day with the pool, so they have a real history before your first campaign. - ### [Sequences](https://ballast.to/sequences) Steps, A to E variants, spintax and variables, previewed against real leads. - ### [Unibox](https://ballast.to/docs/unibox) Replies from every mailbox in one inbox, sorted into Interested, Out of office and the rest. - ### [Guardrails](https://ballast.to/docs/sending-safety) Breakers pause a mailbox, a campaign or the workspace when bounces climb, and say why. - ### [Deliverability Network](https://ballast.to/features#deliverability) SMTP mailboxes connect from one fixed IP used only for mail, so your provider sees the same sender every time. - ### [Import](https://ballast.to/docs/leads) Pull lists from Apollo, Instantly, Smartlead and Lemlist with your own key, take rows from Clay, or drop in any CSV. - ### [API and MCP](https://ballast.to/docs/mcp) Everything in the app is a REST endpoint and a tool your AI can call, with signed webhooks. [See all features](https://ballast.to/features) Deliverability ## Built so people can say no, and you hear it. Cold email works when it reaches one person with a reason to read it, and is easy to refuse. Every plan sends at a person's pace, honors every no, and stops on its own when bounces or complaints say the list is wrong. - ### No means no, everywhere Every email carries one-click unsubscribe, the button Gmail and Yahoo show next to your name. An unsubscribe, a "stop" reply or a spam complaint suppresses the address in every campaign, for good. - ### A reply ends the sequence By default, when someone writes back, Ballast stops emailing them in every campaign, not only the one they answered. A real conversation never gets an automated follow-up. - ### Paced like a person 30 emails a day per mailbox by default, 4 to 10 minutes apart, only in each lead's working hours, with a slow ramp for new mailboxes. - ### It stops you before your list does damage When bounces climb, Ballast pauses the mailbox, the campaign or the whole workspace and says why. A mailbox stops above a 5% bounce rate, and on repeated spam complaints. - ### Tested before your leads see it Send a campaign email to test inboxes at the main providers and see inbox, spam or missing for each, before you launch. Ten tests a day on every plan. [Cold email vs spam: the rules Ballast enforces](https://ballast.to/cold-email-vs-spam) Acceptable use ## What Ballast is not for. Ballast is for one-to-one business email to people whose work makes your message relevant. Accounts that use it for anything below have their sending held or suspended. - Bought, rented or scraped lists of people with no business reason to hear from you - Newsletters, marketing blasts or emailing thousands of strangers - Hiding who you are, fake replies or a brand that isn't yours - Emailing anyone who unsubscribed, said stop or bounced The full rules are in the [Acceptable Use Policy](https://ballast.to/legal/acceptable-use). Write the sequence ## Write it once. Read it as each lead will. Variables with fallbacks, spintax and up to five variants a step. The preview fills in a real lead, warns you when a value is missing, and checks length, spam words and links while you type. Handle the replies ## Every reply from every mailbox, in one inbox. Replies land in the Unibox seconds after they arrive, with the campaign emails folded above them. Out of office pauses the sequence until the return date, unsubscribes stop it, and AI labels the rest if you turn it on. Answer from the same mailbox, in the same thread. Automations ## When a lead replies, clicks or fills in a form, the next step runs itself. Build flows on a canvas: post interested replies to Slack, open the deal in HubSpot or Pipedrive, sort replies with AI, or turn a Typeform signup into a lead in the right campaign. Test a flow before it goes live. On every plan, no Zapier in the middle. When Inbound webhook Your Typeform posts a new signup Lead Create or update lead {{data.email}} into Founders Q4 AI AI step Sort: Hot, Curious, Not a fit If ai.intent is Hot Yes and No paths Tell someone Post to Slack Hot signup: {{lead.company}} Lead Add to a list Nurture History 1. Waiting for an event Three automations as the builder draws them, each with a run playing through. Names are sample data. [How automations work](https://ballast.to/automations) Why Ballast ## Spend the budget on the list, not on the tool. - ### Every feature on every plan No Unibox tier, no seat fee, no warmup add-on. Built-in deliverability network on every plan. The plan only decides how many emails you send. - ### Your data stays yours Your list, your copy and your replies live in your workspace. We don't sell them, share them or train models on them. - ### Your AI can run it Every screen is also an MCP tool for Claude, ChatGPT and Cursor. Nothing sends until you say yes. - ### Steady beats fast Each mailbox sends at its own daily limit, ramps up slowly and pauses when bounces climb. Unlimited mailboxes is not unlimited sending. - ### Replies over opens Open tracking is off by default. Privacy proxies open emails on delivery, so the number mostly counts machines. - ### Switch in an afternoon Connect Instantly, Smartlead or Lemlist with your API key and your lists come straight in, or drop in their exports. Duplicates, suppressed and invalid rows counted for you. Your AI can run it ## Everything you can do in Ballast, your AI can do too.

October 30, 2026 [All posts](https://ballast.to/blog) ## Questions The ones people ask before they switch. Anything else, write to contact@ballast.to. ### How do you protect deliverability if your price is up to 82% lower? The price is lower because we do not charge per seat, mark up mailboxes, or sell safeguards as add-ons. We do not cut corners on deliverability. Ballast paces sending per mailbox with random 4 to 10 minute gaps, matches ESPs (Google mailboxes write to Gmail leads, Microsoft to Outlook), routes traffic over static mail-only IPs, checks SPF, DKIM and DMARC nightly, and pauses campaigns automatically if bounces climb past 3%. [How the breakers work](https://ballast.to/docs/sending-safety) ### Why do you charge per email, not per mailbox or seat? Your emails leave from your own mailboxes, so one more mailbox or teammate costs us next to nothing. Charging for them would only punish you for spreading volume the safe way. The plan counts emails sent a month and active contacts. Leads that finished their sequence, replied, bounced or unsubscribed don't count. ### Does warmup consume from my monthly email quota? No. Warmup never touches your email allowance. If your plan includes 20,000 or 150,000 emails a month, all of them are for real prospect campaigns. Warmup runs separately across the pool (2 on day one, up to 10 a day per mailbox, with real opens and replies) at no extra cost. [How warmup works](https://ballast.to/warmup) ### Which mailboxes can I connect? Google Workspace and Gmail with an app password, Microsoft 365 and Outlook.com with Microsoft sign-in, and any other provider over SMTP and IMAP. Unlimited on every plan. To keep the shared network clean, a new workspace sends up to 1,000 emails a day for its first 7 days. [Connect a mailbox](https://ballast.to/docs/connect-mailbox) ### Can my AI run it? Yes. Every action in the app is also a tool on the Ballast MCP server. claude.ai and ChatGPT sign in with your Ballast account; Claude Code and Cursor use an API key. Launching a campaign, replying, importing and deleting need a second, confirming call, so nothing sends until you say yes. [Connect your AI](https://ballast.to/docs/mcp) ### Can I bring my leads from Instantly or Smartlead? Yes. Connect Instantly, Smartlead or Lemlist with your own API key and import a list or campaign from the Import page, or export a CSV and drop it in. Custom fields come along, leads who unsubscribed there stay suppressed, and duplicates, suppressed and invalid addresses are counted, never imported twice. Apollo and Clay connect the same way. [Switching from Instantly](https://ballast.to/migrate/instantly) ### What happens if I go over my plan? Sending pauses until your next monthly period or until you move up a plan. There is no overage bill. The sidebar shows what's left, and we email you when you reach the limit. ### Is there a free trial? No free plan and no trial: a card is required, because free cold email accounts attract people who burn the shared sending network for everyone. The domain checker is free and needs no signup. If Ballast isn't for you, ask for a full refund within 3 days of a charge. [Check your domain free](https://ballast.to/check) ### Can I keep my clients apart? Yes. Make a workspace per client: each has its own mailboxes, leads, campaigns and Unibox, unlimited seats, and its own plan, so each client's sending is billed on its own. Or run several clients from one workspace on one plan. ### Where is my data, and who sees it? Ballast is hosted in the EU. Your list, your copy and your replies stay in your workspace. We don't sell them, share them or train models on them. Every company we use that touches your data is on our sub-processor list. [Sub-processors](https://ballast.to/legal/sub-processors) The honest part ## Skip Ballast if this is you - ### You have no list or offer yet A sending tool won't find you customers. Work out who you're writing to and why they'd reply, then come back. - ### You want to blast a bought consumer list Our acceptable use policy forbids it and the breakers would pause you anyway. - ### You send newsletters or receipts Use an email service built for that. Ballast is for one-to-one outbound from your own mailboxes. - ### You want guaranteed inbox placement Nobody can sell that honestly. We keep you inside the published rules and stop before a bad day burns a domain.
