Sendpilot and Smartlead cover two different halves of a B2B outbound stack. Sendpilot runs the LinkedIn side: outbound sequences, inbound capture from your posts, a lead database and extractor, ICP scoring and a unified inbox. Smartlead runs cold email: mailboxes, warm-up, sequences and deliverability. Neither does the other's job, which is what makes them a clean pairing rather than an overlapping one.
This post covers what each tool owns, how a lead moves from LinkedIn into an email sequence, and what the combined stack costs per month. If you are still choosing the email half, Smartlead vs Instantly for LinkedIn stacks covers the join in more detail. If you want the argument for running inbound and outbound as one motion, that is the All-Bound revenue engine post.
Why LinkedIn Automation Belongs in a B2B Stack
Cold email reaches a prospect's inbox. LinkedIn reaches the same person where they can see who you are, what you post and who you know. A connection request that lands before an email gives the email its context, and a comment on one of your posts is a warmer signal than any list you can buy. Sendpilot automates that side of the motion on the accounts you connect: outbound sequences built from connection requests, messages, voice notes, profile views and post likes; inbound campaigns that watch one of your posts for comments containing your Action Words, reply to each of those comments automatically and DM the commenters you are already connected to; and lead sourcing from a 300M+ Lead Database, the Sales Navigator lead extractor and post engagers.
The connection gate is the part worth designing around. A commenter who is not yet in your network gets the non-connection reply instead — the one that asks them to connect with you first — so the comment turns into a connection request you can accept, and the DM goes out once they are connected. Everyone who engages with the post is captured as a lead either way, so a reaction still tells you who is paying attention; it just does not start the automation. Only a comment carrying an Action Word does.
Every lead is scored 0–100 against your ICP, and ICP Scoring reads the whole LinkedIn profile: title, seniority, industry and company size, plus skills, endorsements, network, experience and activity. Set a threshold before anything moves to email and only the fit leads cross over. Replies from every connected account land in Unibox, one inbox with lead status and account, campaign and status filters, so nothing waits in a profile nobody is watching.
Volume is deliberately capped. Every connected account gets a dedicated, geo-matched proxy, automatic warm-up and enforced per-account limits: 25 connection requests a day, which is about 175 a week (ten established accounts is roughly 1,750 a week), and no more than 75 messages a day, which is our recommendation rather than a LinkedIn-published figure. Used on its own inside those limits, Sendpilot keeps accounts safe, including the lead extractor. Restrictions come from connecting one account to several tools at once, or from sustained abuse. LinkedIn has no official API for this and endorses no vendor; it acts on behaviour, which is exactly what the limits control. Scale comes from adding accounts, not from pushing one harder — the connection request limits post has the per-account ramp.
What Smartlead Brings on the Email Side
Smartlead is a cold-email platform, and its pricing is the clearest statement of what it is for: four monthly plans, each a single price with unlimited email accounts at no extra cost, listed at Base $39/month, Pro $94/month, Unlimited Smart $174/month and Unlimited Prime $379/month, with 17% off on annual billing. What scales by plan is the ceiling, not the mailbox count. Base is listed at 2,000 contacts and 6,000 sends a month, Pro at 30,000 contacts and 90,000 sends, and the two Unlimited tiers at unlimited contacts with 150,000 and 500,000 sends respectively. These are list prices as of September 2026; check their current pricing page before you budget.
Two details matter for the pairing. First, the warm-up pool is a $59/month add-on on Base and Pro and included on the Unlimited plans, so the entry price is not the price of a warmed-up setup. Second, the API and webhooks start on Pro; Base does not include them. Deliverability testing (SmartDelivery), dedicated sending infrastructure (SmartServers) and client workspaces are further add-ons, and each plan carries a monthly allowance of verified prospect emails, from 2,000 on Base. For anything beyond the pricing grid — inbox rotation, reply handling, what the SmartAgents do on your plan — check their current feature list.
One thing Smartlead does not do is run LinkedIn steps inside its sequences. Its campaign builder exposes email and manual-task steps, and its LinkedIn integrations hand the LinkedIn action to a partner tool. That is the gap Sendpilot fills, and it is why the two do not overlap.
Feature Fit: LinkedIn + Email
| Part of the motion | Sendpilot (LinkedIn) | Smartlead (email) | What the pairing gives you |
|---|---|---|---|
| Lead sourcing | 300M+ Lead Database, Sales Navigator lead extractor, post engagers, ICP scoring on the whole profile | Contact and verified-prospect-email allowances per plan (2,000 each on Base) | LinkedIn-sourced, ICP-filtered leads land in Smartlead with name, title, company, profile URL and score; the email address comes from Smartlead's verified-prospect-email allowance or your own finder |
| Outbound | Connection requests, messages, voice notes, profile views and post likes, rotated across sender accounts at 25 requests a day each | Email sequences across unlimited mailboxes; sends capped per plan | The LinkedIn touch lands first and gives the email its context |
| Inbound | Inbound campaigns trigger on comments carrying your Action Words: an automatic reply to the comment, a DM to commenters you are already connected to, the connect-first reply to everyone else, an ICP score on every captured engager | Not an email-tool job | Engagers who fit your ICP move into an email sequence instead of stalling in a comment thread |
| Replies | Unibox: one inbox across every connected account | Email replies in Smartlead; webhooks fire on replies and lead-category changes from Pro up | One owner per conversation, on whichever channel the prospect answered |
| Hand-off | Webhooks and API from Growth, HubSpot and Slack integrations from Growth, CSV export on every plan | API and webhooks from Pro | Automated on Growth plus Pro; CSV on Launch plus Base |
| Pricing basis | Per LinkedIn account: Launch $79/month or $66/month billed annually, up to Agency $699/month or $583/month billed annually | One price per plan with unlimited email accounts, listed from $39/month | $118/month for one LinkedIn account plus Smartlead Base |
Sendpilot owns the top of the funnel — posts, connections, the first reply — and hands the leads that clear your ICP threshold to Smartlead for the email follow-through. Sendpilot does not send email and does not write it; Smartlead does not run LinkedIn steps itself. That is the whole division of labour, and it is what we mean by All-Bound: inbound and outbound on LinkedIn feeding one pipeline, with email as the follow-through.
Step by Step: Running Sendpilot and Smartlead Together
Smartlead does not list Sendpilot among its native integrations, so the join is one you set up yourself. On Launch and Base it is a CSV; on Growth and Pro it is webhooks and the API. Sendpilot's native integrations are HubSpot and Slack — anything else, Zapier and n8n included, connects through the public API, webhooks or the MCP server, all of which start on Growth. Either way the sequence is the same:
- Build the list in Sendpilot: Pull leads from the Lead Database, the Sales Navigator lead extractor or an inbound campaign on one of your posts. Enrichment works on leads from those three sources, not on an imported CSV, and it fills in LinkedIn data — title, seniority, company, headcount and profile URL — not contact details. The email address comes on the Smartlead side, from its verified-prospect-email allowance (2,000 a month on Base, 30,000 on Pro) or your own email-finding provider. Score everything against your ICP and set a threshold, say 80, for what goes any further.
- Run the LinkedIn sequence: Connection request, a short message, a voice note where it fits, profile views and post likes as the softer touches, at 25 requests a day per account with warm-up applied automatically. Work replies in Unibox and mark who is interested, who is not and who has gone quiet.
- Hand the right leads to Smartlead: On Growth and above, a webhook fires on the events Sendpilot emits, such as an accepted connection or a reply, and the API carries the lead — name, title, company, LinkedIn URL and ICP score — into Smartlead, which accepts it on Pro and above. The email address comes from Smartlead's verified-prospect-email allowance or your own email-finding provider; the HubSpot and Slack integrations (also Growth and up) cover the CRM record and the notification. On Launch, export the segment as a CSV and import it. Sendpilot does not send email or write it; from here the copy and the sending are Smartlead's.
- Write the email sequence in Smartlead: Reference the LinkedIn touch that already happened ("Good to connect last week — here is the thing I mentioned"). Budget for the warm-up pool: it is a $59/month add-on on Base and Pro, and included on the Unlimited plans.
- Route replies to one owner: Email replies stay in Smartlead and LinkedIn replies stay in Unibox, so decide which channel owns the conversation once a prospect answers and nobody gets the same follow-up twice. Smartlead's webhooks fire on email replies and lead-category changes from Pro up, which is your signal to pause the LinkedIn side.
- Read both halves together: Acceptance rate and reply rate per LinkedIn account, open and reply rate per email campaign, and the number of leads that crossed from one to the other. Hold the LinkedIn ramp at a step for another week if acceptance drops below about 25%, and move the ICP threshold before you move the volume.
What the Combined Stack Costs
Sendpilot is priced per LinkedIn account, never per user. Launch is $79/month, or $66/month billed annually, for one LinkedIn account with 800 credits a month for enrichment, extraction and scoring. Growth is $329/month, or $274/month billed annually, for five accounts and 4,000 credits, and it is the first plan with the API, webhooks and the HubSpot and Slack integrations. Agency is $699/month, or $583/month billed annually, for 25 accounts and 20,000 credits, with whitelabel. Enterprise is custom, from $1K+, and sales-led. Extra accounts are $79, $49 and $29 a month on Launch, Growth and Agency respectively. The full grid is on /pricing.
Smartlead is listed at $39/month for Base and $94/month for Pro (about $32.50 and $78.30 with annual billing), one price each, with unlimited email accounts on both. The API and webhooks start on Pro.
So the honest entry figure for the stack is $118/month: Launch at $79 plus Smartlead Base at $39, or about $99/month with both billed annually ($66 plus $32.50). That buys one LinkedIn account, unlimited mailboxes with 6,000 sends a month, and a CSV hand-off. Add Smartlead's warm-up pool on Base and it is $177/month. If you want the hand-off automated, the floor moves to Growth plus Pro: $423/month on monthly billing ($329 plus $94), or about $352/month billed annually ($274 plus $78.30), for five LinkedIn accounts, 90,000 email sends a month and webhooks on both sides. Smartlead's figures are list prices as of September 2026 — check their current pricing page.
What to Expect
We will not put a reply-rate or revenue multiple on this pairing, because the number depends on your list, your offer and how warm the LinkedIn touch was before the email went out. What teams we work with typically see is more mundane and more useful: acceptance on LinkedIn tells you within a week whether the ICP is right, email replies improve when the first line references a LinkedIn interaction that actually happened, and the two channels catch each other's non-responders. Treat the first month as calibration. Run both, read the numbers side by side, and change the ICP threshold before you change the volume.
Where Sendpilot Fits
If you already run Smartlead, keep it; it is the email half. Add Sendpilot for the LinkedIn half: outbound sequences, inbound capture from your posts, ICP Scoring and enrichment on the leads Sendpilot sources. A solo operator starts on Launch with a CSV hand-off; a small team that wants the webhook join starts on Growth; an agency running client accounts starts on Agency. Sendpilot's free trial needs a card on file, and for Smartlead's trial terms check their current pricing page — the cheapest test is to run both for a month.
