Breakcold
Oxygen runs email and LinkedIn sequences, signals that enroll leads and workflows next to a CRM with deals, from $49 a month with no seat per user. Breakcold is a CRM with one inbox for email, LinkedIn, WhatsApp and Telegram, and it leads on CRM depth: email and calendar sync and permissions per role and account.

Choose OXYGEN ifChoose Breakcold if| Team | Pick | Why |
|---|---|---|
| A sales team of 3 on email and LinkedIn | OXYGEN | $118.50 a month with sequences included; Breakcold costs $159 before a sending tool. |
| A solo founder on a tight budget | OXYGEN | A free workspace with the CRM and no time limit; Breakcold is $99 a month after a 14-day trial. |
| A team that sells on Telegram and WhatsApp | Breakcold | Telegram and WhatsApp chats, groups included, land on each record; Oxygen's sequences have WhatsApp but no Telegram. |
| A team that wants its CRM synced with email and calendars | Breakcold | Email and calendar sync with roles and rights per account; Oxygen has no calendar sync. |
| An agency with a workspace per client | Either | Both bill client workspaces together; Breakcold adds client logins, Oxygen a credit cap per client. |
Breakcold's help center lists Instantly, Smartlead and Zapmail for cold email and HeyReach for LinkedIn outreach. Oxygen sends email and LinkedIn steps from one sequence, with inboxes at $4 a month including warm-up.
Sequences and inbox in detailBreakcold leaves out LinkedIn automation by design: reps message from its inbox and like posts from a feed. Oxygen runs invites, messages, InMail, likes and comments in the cloud at $34 a month per account.
LinkedIn automation in detailBreakcold's post feed and hiring flags show activity, and Trigify or RB2B push leads in, but nothing enrolls a lead. In Oxygen, a profile view or post reaction can enroll the lead in a sequence.
Signals in detailBreakcold offers a free post preview tool, and its help center lists Scripe and SuperX for posting. Oxygen schedules LinkedIn and X posts, with approval before each one goes out and analytics after.
LinkedIn content publishing in detail| Criterion | OXYGEN | Breakcold |
|---|---|---|
| Lead data and signals | ||
| Lead data from multiple vendorsHow many providers the email waterfall tries on the vendor's credits, and how lookups are billed. | Email and phone waterfalls across 17 and 13 providers, charged only when one finds the value, on plan credits or your own keys from the $99 plan. Even | Email and phone waterfalls across 20+ and 12+ providers, paid in tokens only on a hit: 10 an email, 80 a phone, from 1,500 a month in the plan. Person and company data is free. No own keys found. Even |
| SignalsWhich buying signals it captures, what they cost, and whether one can start outreach. | LinkedIn profile viewers, new followers and post reactions from your connected accounts at no extra cost, plus hiring, funding, news, tech-stack and job-change searches on credits. A signal can start a workflow or enroll the lead in a sequence. Ahead | A feed of prospects' LinkedIn posts to like and comment on by hand, and hiring and open-to-work flags from free enrichment. Trigify, Gojiberry and RB2B push leads in. No signal starts outreach by itself. |
| Email, LinkedIn and more channels | ||
| Email deliverabilityWarm-up, inbox buying, placement tests, rotation, send limits, bounce protection, then the price of an inbox. | Google Workspace and Microsoft 365 inboxes at $4 a month with warm-up included, or a Microsoft tenant at $40 a month for up to 100 inboxes. Placement tests from $1 an inbox a month, inbox rotation, daily limits per mailbox and a bounce auto-pause. Ahead | Sends one-to-one email from connected Gmail, Outlook or IMAP mailboxes, with rate limits per account. No warm-up, inbox buying, placement tests, rotation or bounce protection; its help points to Instantly or Smartlead. |
| LinkedIn automationWhich steps run on their own, how the account connects, and what 2 senders cost a month. | Runs in the cloud with no browser extension: visits, invites, messages, InMail, follows, likes and comments. $34 a month per connected account, every action included. Ahead | No automation, by design: a rep sends each message from the shared inbox and likes posts from a feed. Accounts connect in the cloud by login or cookies; the plan covers 2, then $10 each. |
| WhatsApp, calls and SMSChannels beyond email and LinkedIn inside the same sequence. Beta channels do not count. | WhatsApp steps at $34 a month per number, over a linked-device connection. Calls from a web softphone are in beta. No SMS. Ahead | WhatsApp and Telegram chats, groups included, answered one at a time from the shared inbox, and calls synced from Aircall, CloudTalk, JustCall or Ringover. No sequences to hold them, and no SMS. |
| Sequences and inboxMixed channels, branches, A/B tests, reply stops on every channel, one inbox, AI replies. | One sequence mixes email, LinkedIn, WhatsApp and call tasks, branches on connection state, signals or lead data, tests up to 26 versions of a step, and stops a lead when they reply on any channel. Replies land in one inbox with AI triage and drafted answers. Ahead | No sequences: it uses AI follow-ups instead of step-based builders. One inbox for email, LinkedIn, WhatsApp and Telegram, with AI rewrites and drafted follow-ups from Karen, a $12-a-month add-on. |
| LinkedIn content publishingScheduling posts, approving them before they go out, and reading their analytics. | Schedule LinkedIn and X posts, approve each before it goes out, and read LinkedIn and X analytics. Ahead | No post scheduling, approvals or post analytics found. It offers a free post preview tool, and its help center lists Scripe and SuperX for posting. |
| CRM and integrations | ||
| Built-in CRMDeals, a pipeline and custom records in the same workspace, and what they cost. | Companies, people, deals and objects you define, a deals pipeline, and an activity timeline where replies land. Free on every plan, the free one included. Even | People, companies, deals and custom objects, unlimited Kanban pipelines, and a record timeline with every email, LinkedIn, WhatsApp and Telegram message, all in its one plan. Even |
| CRM depthWhat a full CRM adds: email and calendar sync, reports, permissions, boards and a mobile app. | Dashboards for pipeline, outbound and replies, and a deals pipeline board. No calendar sync, permissions per record or mobile app. | Email and calendar sync from Google, Outlook or IMAP, a Daily Brief dashboard with pipeline KPIs, 4 workspace roles plus read and reply rights per account, and Kanban boards. No mobile app yet. Ahead |
| Agencies and client workspacesSeparate client workspaces, one bill across them, and per-client spend limits. | A separate workspace per client, client workspaces billed from one plan, and a monthly credit cap per client. Client logins are in beta. Even | A workspace per client under one organization and one bill, extra workspaces at $5 a month, and clients invited as read-only viewers. No per-client spend limits found. Even |
| Workflows and AI | ||
| Workflow automationAutomations on schedules, webhooks and events, with approvals and run logs, built in. | Built in: schedules down to every minute on paid plans, webhooks, API calls and 77 workspace events as triggers, with approval steps, retries and a log of every run. Ahead | Webhooks in with AI mapping, and out on 14 record events with 3 tries and 30 days of logs. Enrichment and pushes to outreach tools fire on record changes; AI employees work review-first. No schedules. |
| AI and agent accessAn in-app assistant, AI over your rows, cited research, and MCP, CLI and API access. | A Copilot in the web app that asks before sends and larger paid steps unless you turn on Auto-approve, AI columns over your rows, a research agent that cites its sources, an MCP server, a CLI and an API. Ahead | Free AI summaries on records, AI filters and formulas, and a meeting assistant to chat with; a chat per record is coming soon. An MCP server with 62 tools and an API, billed in tokens. No CLI. |
| Pricing and security | ||
| Pricing modelWhat you pay for, and the monthly list price for three common setups. | One plan from $49 a month per workspace, paid in credits, with no seat per user. A LinkedIn account uses $34 of credits a month. Ahead | One plan: $99 a month with 1 seat, 2 connected accounts and 1,500 tokens; each extra seat or account is $10. Quarterly billing saves 10%, yearly 20%. It sends no sequences. |
| Free plan and trialWhat you can use before paying, and for how long. | A free workspace with 1,000 credits once, the CRM, tables and workflows, and no time limit. Sending needs a paid plan. Ahead | No free plan: a 14-day trial with no credit card, which may offer limited functionality and ends on its own. The plan is $99 a month after it. |
Across 14 criteria: OXYGEN ahead on 10 (signals, deliverability, LinkedIn, extra channels, sequences, workflows, AI, price, content publishing, free plan), Breakcold ahead on 1 (CRM depth), even on 3. How we compared
Even on providers. Breakcold's waterfall tries 20+ email and 12+ phone providers and charges tokens only on a hit, and person and company data is free without limit. Oxygen's waterfalls try 17 email and 13 phone providers, charge only on a hit, and take your own keys from the $99 plan.
Partly. Breakcold shows a feed of prospects' LinkedIn posts, hiring flags from free enrichment, and leads pushed in by Trigify, Gojiberry or RB2B, and none of these starts outreach. Oxygen reads profile viewers, new followers and post reactions at no extra cost, and a signal can enroll the lead in a sequence.
No. Breakcold sends one-to-one email from the mailboxes you connect, and its help center points to Instantly, Smartlead or Zapmail for cold email. Oxygen sends sequences itself, with inboxes at $4 a month including warm-up, plus placement tests, rotation, daily limits and a bounce pause. See mailboxes.
No, by design: Breakcold's help center says it avoids features that can get accounts banned, so a rep messages from its inbox and likes posts from a feed. Oxygen runs visits, invites, messages, InMail, likes and comments in the cloud at $34 a month per account, so 2 senders cost $73.70.
Not in a sequence. Breakcold syncs WhatsApp and Telegram chats, groups included, for one-to-one replies, and calls from Aircall, CloudTalk, JustCall or Ringover. Oxygen puts WhatsApp steps in a sequence at $34 a number; its calls are in beta and not counted. Neither sends SMS, and Telegram is Breakcold's alone.
No. Breakcold uses AI follow-ups instead of step-based sequences, so nothing branches or stops on a reply. Its strength is the inbox: email, LinkedIn, WhatsApp and Telegram in one place, with AI rewrites and drafted follow-ups. Oxygen's sequences mix channels, branch, test up to 26 versions and stop on any reply.
No. Breakcold has a free post preview tool, and its help center lists Scripe and SuperX for posting on LinkedIn or X. Oxygen schedules LinkedIn and X posts, asks for approval before each one goes out and reads their analytics. See how publishing works.
Both are full CRMs. Breakcold has people, companies, deals, custom objects, unlimited pipelines and a timeline with every channel's messages. Oxygen's CRM has the same parts, logs sequence replies on the timeline, and is free on every plan, the free one included. The CRM depth row shows where they differ.
Yes, deeper than Oxygen's. Breakcold syncs email and calendars, sets 4 workspace roles plus read and reply rights per connected account, and has Kanban boards and a Daily Brief dashboard, though no mobile app yet. Oxygen has dashboards and a pipeline board, with no calendar sync, record permissions or mobile app.
Both. Breakcold runs each client in its own workspace under one organization and bill, $5 a month per extra workspace in its help center, and clients can join as read-only viewers. Oxygen bills client workspaces from one plan with a monthly credit cap per client; its client logins are in beta.
Partly. Breakcold's webhooks take data in with AI mapping and send 14 record events out with retries and logs, and enrichment and pushes to outreach tools fire on record changes, but it has no scheduled triggers. Oxygen's workflows also run on schedules and 77 workspace events, with approval steps and a log of every run.
Both let coding agents in: Breakcold has an MCP server with 62 tools and an API, billed in tokens, plus free AI summaries and a meeting assistant. Oxygen adds a Copilot that asks before sends and larger paid steps by default, AI columns, a research agent that cites sources and a CLI.
Oxygen costs less in all 3 setups below, and its price includes sending. Breakcold is one plan at $99 a month with 1 seat and 2 connected accounts, then $10 per extra seat or account, with outreach in a second tool. Oxygen is one plan per workspace from $49, paid in credits. See Oxygen pricing.
No free plan. Breakcold gives a 14-day trial with no card, then charges $99 a month. Oxygen has a free workspace with 1,000 credits once, the CRM, tables and workflows, and no time limit. Sending needs a paid plan; until then a team can keep its records in Oxygen for free.
| Setup | OXYGEN a month | Breakcold a month |
|---|---|---|
| 1 person on email and LinkedIn | $49the $49 plan | $99The Only Plan, 1 seat and 2 accounts; sequences and LinkedIn automation need other tools; $79.20 billed yearly |
| 3 people on email and LinkedIn | $118.50the $99 plan plus 1,500 credits in top-ups | $1593 seats and 6 connected accounts; sequences and LinkedIn automation need other tools; $139.20 billed yearly |
| A team on email only, 3 inboxes | $49the $49 plan | $1091 seat and 3 mailboxes for one-to-one email; cold email needs Instantly or Smartlead; $89.20 billed yearly |
Run both for a while: keep Breakcold as the inbox for current clients and start new outbound in Oxygen, which reads and writes Breakcold records, notes and tasks through its API on your own Breakcold key from the $99 plan.
Yes, in the 3 setups on this page, on monthly billing: $49 against $99 for one person on email and LinkedIn, $118.50 against $159 for 3 people, and $49 against $109 for email only. Breakcold's price covers its CRM and inbox; outreach needs another tool.
No. Its help center says Breakcold is not LinkedIn automation software and avoids features that can get accounts banned; you send messages from its inbox and like posts from a feed. Oxygen runs invites, messages, InMail, likes and comments in the cloud at $34 a month per account.
No. Breakcold sends one-to-one email from connected mailboxes, with no sequences, warm-up or mailbox buying. Its help center lists Instantly, Smartlead and Zapmail for cold email, and Instantly and Smartlead push positive replies back into Breakcold. Oxygen sends email and LinkedIn steps from one sequence and stops a lead when they reply.
$99 a month for its only plan, with 1 seat, 2 connected accounts and 1,500 tokens; each extra seat or account is $10. Quarterly billing saves 10% and yearly 20%, or $79.20 a month for the base plan. Tokens pay for email and phone lookups and AI features.
Yes. Export people, companies and deals as CSV, up to 10,000 records per file, import them into Oxygen's CRM, and reconnect your mailboxes, LinkedIn and WhatsApp. Message timelines and Telegram stay in Breakcold. Move each contact before your first sequence reaches them, so nobody hears from both tools.
Yes: a hosted MCP server with 62 tools for records, tasks, notes, the inbox and meetings, with most calls at 0.2 or 0.4 tokens. Oxygen has an MCP server too, plus a CLI, a Copilot in the app and a research agent that cites its sources.
When the CRM matters most and outreach already runs elsewhere: Breakcold syncs email and calendars, sets roles and rights per account, keeps Telegram and WhatsApp chats on each record, and gives agencies client logins. On the other rows of this comparison, Oxygen leads or the two are even.
