Email deliverability in detail
Deepline sends no LinkedIn steps; it adds profiles to a HeyReach campaign you create there first. Oxygen runs visits, invites, messages and InMail in the cloud at $34 a month per account.
LinkedIn automation in detail
Deepline's llms.txt, the summary it publishes for AI tools, names HubSpot, Salesforce or Attio as the system of record that Deepline writes to. Oxygen keeps companies, people and deals in its own CRM, with every reply on the timeline, on every plan.
Built-in CRM in detail| Criterion | OXYGEN | Deepline |
|---|---|---|
| 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, on plan credits or own keys from the $99 plan. Managed finders charge on a hit; email checks bill even on a miss. | Its email-finding rate card lists 13 email finders; counting person-enrichment tools too, 21 return work emails on Deepline credits, plus phone waterfalls. Its pages disagree on whether misses cost credits; own keys carry no markup. Ahead |
| Tables for lead listsSpreadsheet tables for building lists: relations, formulas, enrichment columns and rows per table. | Tables you edit like a spreadsheet, with relations between tables, formula columns, and enrichment and AI columns that fill every row. Up to 1,000,000 rows per table on the $49 plan and 3,000,000 from the $199 plan. Ahead | No spreadsheet tables. Lists run as CSV files through code Plays, with row results in Runtime Sheets and a Postgres database you query with SQL; its llms.txt lists no row limit per workflow. |
| Own contact databaseContacts in the vendor's own database, searchable in the product. | No contact database of its own. Searches run through data providers on credits, and through Apollo's database on your own Apollo key. | A free company database of about 35 million records from a People Data Labs snapshot, searched with SQL; its pricing page calls it a company and people database. People search costs credits. Ahead |
| 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 no email. It pushes leads into Instantly, Smartlead, lemlist and 7 other sequencers, which own warm-up, mailboxes and limits; its llms.txt points to Resend or Postmark for transactional email. |
| 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 | Runs no LinkedIn steps itself. It reads LinkedIn profiles, posts and engagers through HarvestAPI and adds profiles to an existing HeyReach or lemlist campaign, each on its own plan. |
| 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 | No WhatsApp, call or SMS steps of its own. It can push contacts to Nooks, Outreach or Salesloft, which run calls and tasks on their own accounts. |
| 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 or inbox of its own. Plays add leads to campaigns in Instantly, Smartlead, lemlist or HeyReach, and replies stay in those tools. |
| 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. Ahead | No CRM of its own. Its llms.txt names HubSpot, Salesforce or Attio as the system of record that Deepline writes to, and its docs call its database working state. |
| Works with your stackWhich CRMs sync both ways. Push-only syncs and imports do not count. | Two-way sync with HubSpot, one-way sync to Attio and an import from Pipedrive. No Salesforce sync. Pushes leads into Instantly, Smartlead, lemlist and HeyReach campaigns, and has a public API and webhooks. | On Growth, Salesforce, HubSpot and Attio sync into Deepline in real time and Plays write back. Pipedrive, Zoho and Affinity take Play reads and writes. Pushes to 10 sequencers; webhooks, API and Slack. Ahead |
| Workflows and AI | ||
| AI and agent accessAn in-app assistant, AI over your rows, cited research, and MCP, CLI and API access. | An in-app AI assistant whose workspace chat starts on Auto-approve; turn it off to approve sends and larger paid steps. AI columns over your rows, a research agent that cites its sources, an MCP server, a CLI and an API. Ahead | Built for your own agent: a CLI and TypeScript SDK for agents that run shell commands, a remote MCP server for those that cannot, and a REST API. Plays run AI over rows and cited Exa research. No in-app assistant found. |
| 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. Even | Pay as you go at $0 a month plus usage, Growth at $395 with $200 of usage included, Enterprise custom. 10 credits are $1 and there is no seat charge. Sending needs a separate sequencer. Even |
| Security and complianceAudits, SSO and the documents a security review asks for. | A public DPA and subprocessor list. No SOC 2 report, ISO 27001 certificate, SSO or public status page. | Its security page claims SOC 2 Type 2 with the report under NDA, though a comparison page says in progress. SSO on Enterprise, a public subprocessor list and status page; DPAs shared in procurement. Ahead |
| Data access and exportGetting your data out: CSV, API, SQL, or your own database. | Free CSV export, export through the API, read-only SQL over your workspace, and the option to attach your own Postgres. Even | CSV export of any run, SQL reads through the API at up to 1,000 rows a call, a direct Postgres connection you can pg_dump, and queries against your own Postgres or warehouse. Even |
| Free plan and trialWhat you can use before paying, and for how long. | A free workspace with 250 credits once, the CRM, tables and workflows, and no time limit. Sending needs a paid plan. Even | Pay as you go has no platform fee, card or minimum, with no time limit found; usage costs credits. Own-key calls are free up to 50K a month and the company database search is free. Even |
Across 14 criteria: OXYGEN ahead on 7 (tables, deliverability, LinkedIn, extra channels, sequences, CRM, AI), Deepline ahead on 4 (lead data, CRM syncs, security, own database), even on 3. How we compared
Deepline leads here. Its email-finding rate card lists 13 email finders, and counting person-enrichment tools such as Prospeo, 21 return work emails on Deepline credits. Its waterfall tries 7 in order, own keys carry no markup, and its pages disagree on whether managed misses cost credits. Oxygen's waterfalls try 17 email and 13 phone providers.
Only Oxygen has spreadsheet tables. Deepline runs lists as CSV files through code Plays and keeps each run's rows in Runtime Sheets and a Postgres database you query with SQL. Oxygen's tables work like a spreadsheet, with relations, formulas and AI columns, up to 1,000,000 rows on the $49 plan.
About 35 million company records from a People Data Labs snapshot, free to search with SQL. Its pricing page calls it a company and people database. People search costs credits. Oxygen has no database of its own and searches through data providers, or Apollo on your own key.
Deepline sends no email, so it has none of these parts: leads go to Instantly, Smartlead, lemlist or another sequencer. Oxygen sends email itself, with Google and Microsoft inboxes at $4 a month, warm-up, placement tests, rotation, daily limits and a bounce pause. See mailboxes.
No. Deepline reads LinkedIn profiles and posts through HarvestAPI and adds profiles to an existing HeyReach or lemlist campaign, which sends on its own plan. Oxygen runs visits, invites, messages, InMail, follows, likes and comments in the cloud at $34 a month per account. Two senders cost $73.70 a month in all, plan included.
Deepline has no WhatsApp, call or SMS steps of its own. It can push contacts to Nooks, Outreach or Salesloft, which run calls and tasks on their own accounts. Oxygen adds WhatsApp steps to the same sequence as email and LinkedIn, at $34 a month per number. Calls are in beta, and there is no SMS.
No. Deepline adds leads to campaigns in the sequencer you already run, and replies stay there. Oxygen mixes email, LinkedIn and WhatsApp in one sequence and branches on lead data. It tests up to 26 versions of a step and stops a lead who replies anywhere. See how sequences work.
No. Deepline's llms.txt names HubSpot, Salesforce or Attio as the system of record that Deepline writes to, so deals and replies live in your CRM. Oxygen's CRM keeps companies, people, deals and objects you define, with every reply on the timeline, free on every plan.
Deepline leads here. On Growth, Salesforce, HubSpot and Attio sync into Deepline in real time and Plays write back; Plays also read and write Pipedrive, Zoho and Affinity. Oxygen syncs both ways with HubSpot, pushes to Attio, imports from Pipedrive and has no Salesforce sync. See the integrations page.
Coding agents drive both through an MCP server, a CLI and an API, and both run AI over rows with cited research. Deepline's pages show no assistant inside its app. Oxygen adds an AI assistant in the web app, where you choose whether it asks before sends and larger paid steps. See the CLI and MCP server.
Deepline costs $0 or $395 a month plus usage, and a small team that sends also pays for a sequencer. Deepline sends no email or LinkedIn, so the table shows no Deepline price for these setups. Oxygen is one plan per workspace from $49, sending included. See Oxygen pricing.
Deepline is ahead. Its security page claims SOC 2 Type 2 with the report under NDA, though its ZoomInfo comparison page says in progress. It adds SSO on Enterprise, a public subprocessor list and a status page. Oxygen publishes a DPA and a subprocessor list, with no SOC 2 report, SSO or status page.
Both make your data easy to take out. Deepline exports runs to CSV and answers SQL through its API at up to 1,000 rows a call. Each workspace gets a Postgres database you can copy out in full. Oxygen has free CSV export, API export, read-only SQL and the option to attach your own Postgres.
Both are free to start. Deepline's Pay as you go has no platform fee, card or minimum. You pay for managed data as you use it, and own-key calls are free up to 50K a month. Oxygen's free workspace includes 250 credits once, the CRM, tables and workflows. Sending needs a paid plan.

Oxygen has no Deepline integration. The path both document runs through HubSpot: Deepline Plays write contacts to HubSpot, and Oxygen syncs HubSpot both ways.
Deepline's own Clay page says to test it: run one real job in both and record the failed rows. It says the main difference is where the work lives: Clay's visual workspace, or Plays a coding agent runs. Clay caps tables at 50,000 rows on Launch and Growth, and Deepline lists no row limit. Clay's docs suggest Enterprise, with bulk enrichment, for 10,000+ records a month, and Deepline advises a warehouse for audiences over 1 million rows.
Deepline charges a monthly platform fee plus usage: $0 on Pay as you go or $395 on Growth, at 10 credits to $1. Growth includes $200 of usage; no plan charges per seat. Own keys carry no markup, with 50K calls a month free on Pay as you go. Its pages disagree on whether managed misses cost credits. Oxygen starts at $49 a month with sending.
Deepline's CLI is an npm package that coding agents run in a shell, and its setup adds skills for Claude Code, Codex and Cursor. Chat apps such as Claude Desktop use its remote MCP server, the standard way AI apps connect to outside tools. They add code.deepline.com/api/v2/mcp as a connector and sign in. Oxygen has a CLI and a hosted MCP server too, plus an AI assistant in the web app.
No. Deepline pushes enriched leads into sequencers such as Instantly, Smartlead, lemlist and HeyReach, which do the sending. Its llms.txt points to Resend or Postmark for transactional email. Oxygen sends email, LinkedIn and WhatsApp steps from its own sequences, with inboxes at $4 a month.
Its security page says yes: a SOC 2 Type 2 report verified by Sensiba and shared under NDA during procurement. Its ZoomInfo comparison page still says in progress. SSO is on its Enterprise plan. Oxygen has no SOC 2 report; it publishes a DPA and a subprocessor list.
Yes, through HubSpot, though Oxygen has no Deepline integration. Deepline Plays write enriched contacts to HubSpot, and Oxygen syncs HubSpot both ways. Both can also push leads into the same Instantly, Smartlead, lemlist or HeyReach campaigns.
