The Oxygen deals board with deals in Lead, In Progress, Won and Lost

The CRM starts on Pro, with no company records

Automations cannot start from a webhook or wait for approval

SmartAgents run on a schedule or on email replies, opens and clicks, and Smartlead documents no webhook triggers or approval steps. Oxygen's workflows start on a schedule, a webhook or one of 77 workspace events, with approval steps, retries and a run log.

Across 12 criteria: OXYGEN ahead on 8 (lead data, tables, signals, LinkedIn, sequences, CRM, workflows, AI), Smartlead ahead on 3 (price, agency features, own database), even on 1. How we compared

Lead data and signals: Oxygen vs Smartlead

Where does Smartlead get its lead data, and how does Oxygen's compare?

From its own SmartProspect database: a credit unlocks a verified email, or a phone for calls, from 2,000 a month on Base or 30,000 on Pro behind a $59 monthly add-on, included from Unlimited Smart. It names no provider count. Oxygen's waterfalls try 17 email and 13 phone providers on plan credits and charge only on a hit.

Does Smartlead have tables for building lead lists?

No. Leads sit in campaign and saved lists with up to 40 custom variables each, capped at 2,000 contacts on Base and 30,000 on Pro, and lists do not link, calculate or enrich. Oxygen's tables relate to each other, run formulas and fill enrichment and AI columns, up to 1,000,000 rows each on the $49 plan.

Does Smartlead track buying signals, and which does Oxygen capture?

Not as a self-serve feature. Its pages mention live intent signals, but SmartProspect documents only role, company and location filters, and hiring and website-visitor signals come with its managed service. Oxygen reads profile viewers, new followers and post reactions at no extra cost, and a signal can enroll a lead. See signals.

How big is Smartlead's own contact database?

300M+ verified business profiles, searchable in SmartProspect. Each unlocked contact takes a credit from an allowance that needs a $59 monthly add-on on Base and Pro and is included from Unlimited Smart. Oxygen has no database of its own; it searches through data providers on credits, and Apollo's database on your own key from the $99 plan.

Email, LinkedIn and more channels: Oxygen vs Smartlead

How does Smartlead protect deliverability, and what does Oxygen include?

Even: both have all six parts and a close inbox price. Smartlead includes unlimited warm-up, sells Google and Outlook mailboxes at $4.50 a month, runs placement tests from $49 a month, rotates inboxes and pauses at a bounce rate you set. Oxygen's inboxes are $4 a month with warm-up, with placement tests from $1 an inbox. See mailboxes.

Does Smartlead automate LinkedIn, and what does a sender cost?

No. Its FAQ says LinkedIn steps come through the HeyReach and Aimfox integrations, which need their own accounts and prices; inside Smartlead a manual task can remind a rep. Oxygen runs visits, invites, messages, InMail, follows, likes and comments in the cloud at $34 an account, so 2 senders cost $73.70 a month.

Can one Smartlead sequence mix channels, and where do replies land?

Email, call and manual-task steps only; LinkedIn runs in HeyReach or Aimfox. Subsequences branch on replies, opens, clicks or categories, A/B tests compare versions, a reply stops the lead, and replies land in one Master Inbox with AI-drafted answers. Oxygen puts email, LinkedIn and WhatsApp in one sequence and one inbox. See how sequences work.

CRM and integrations: Oxygen vs Smartlead

Does Smartlead have a CRM, and how does Oxygen's compare?

Partly, from Pro. Smart Funnel is a kanban pipeline of leads with notes, tags, deal value and the email thread on a timeline; Base lacks it, and there are no company records or custom objects. Oxygen's CRM has companies, deals on a pipeline board, objects you define and every reply on the timeline, free on every plan.

Can an agency run its clients in Smartlead?

Yes, and Smartlead leads this row: each client workspace is $29 a month from Pro, 3 come with Prime, all on the agency's one bill, with credit limits per client, client logins with set permissions and white-label on your own domain. Oxygen bills client workspaces from one plan with a monthly credit cap each; client logins are in beta.

Workflows and AI: Oxygen vs Smartlead

Can Smartlead automate work outside a sequence?

Yes, with SmartAgents: describe a task or pick a template, trigger it on a schedule or an email reply, open or click, test it and deploy; every run is logged. No webhook triggers or approval steps are documented. Oxygen's workflows start on a schedule, a webhook or one of 77 workspace events, with approval steps, retries and a run log.

What can AI do in Smartlead, and can coding agents drive it?

SmartAssistant, on every plan, builds campaigns, adds leads, runs diagnostics and asks before risky steps; coding agents get an MCP server, a CLI and an API from Pro. It documents no AI columns or cited research. Oxygen adds AI columns over your rows and a research agent that cites its sources. See the MCP server.

Pricing and security: Oxygen vs Smartlead

How does Smartlead pricing compare with Oxygen for a small team?

Smartlead's list prices are lower in all 3 setups below, before LinkedIn and mailboxes: LinkedIn needs a HeyReach or Aimfox account, and teammates need Pro. Oxygen is one plan per workspace paid in credits, and its prices include each sender's LinkedIn account and the inboxes. Full prices are on Oxygen pricing.

Oxygen vs Smartlead FAQ

Is Oxygen cheaper than Smartlead?

Not on list price. One person costs $39 a month on Smartlead Base for email alone, against $49 on Oxygen for email and LinkedIn; 3 people cost $94 on Pro against $118.50. Smartlead's LinkedIn needs a HeyReach or Aimfox account, and mailboxes bought from it cost $4.50 each a month; Oxygen's prices include both.

Does Smartlead do LinkedIn outreach?

Not by itself. Its FAQ says LinkedIn steps come through the HeyReach and Aimfox integrations: a SmartAgent pushes leads into their campaigns when someone replies, opens or clicks, and each tool needs its own account. Oxygen runs LinkedIn in the cloud at $34 a month per account, in the same sequence as email.

Are SmartProspect leads free?

Only on the higher plans: Unlimited Smart includes 50,000 verified emails a month and Unlimited Prime 170,000. On Base and Pro the allowance needs a $59 monthly add-on, after 2,000 credits to try it. Oxygen has no database; its waterfalls try 17 email providers on plan credits and charge only on a hit.

Is Smartlead good for agencies?

Yes, it is built for them and leads that row: $29 a month per client workspace from Pro, 3 included on Prime, with white-label, client logins and credit limits per client on one bill. Oxygen bills client workspaces from one plan with a credit cap each; its client logins are in beta.

Can I keep Smartlead and use Oxygen next to it?

Yes. Oxygen can source and enrich leads, then push them into a Smartlead campaign on your own Smartlead key from the $99 plan; Smartlead issues API keys from Pro. Smartlead keeps sending and replies land in its Master Inbox, while Oxygen holds the data, LinkedIn and the CRM.

Can I move from Smartlead without losing my campaigns?

Leads, lists and your own mailboxes move; campaign history stays in Smartlead. Export leads as CSV into an Oxygen table or the CRM, connect your mailboxes and rebuild each sequence, adding LinkedIn steps where HeyReach or Aimfox ran them. Move a list only after its Smartlead campaign ends, so nobody gets the same email twice.

When is Smartlead the better choice?

When you run cold email for many clients and want white-label workspaces, when you want a 300M+ contact database in your sender, or when you send email only from one login at the lowest list price. On the other rows here, Oxygen leads or the two are even.
