LinkedIn Conversation Ads: the 2026 playbook, examples and benchmarks
To run LinkedIn conversation ads that book meetings, send them to a retargeting pool rather than a cold list, from a named person, with one short message and one button. Bid LinkedIn's minimum. Route replies to a Lead Gen Form or straight to a calendar. The median account pays $200 a lead at a 42.6% open rate.

What LinkedIn conversation ads and message ads are
LinkedIn calls the pair Sponsored Messaging. Both land in the member's LinkedIn inbox as a message from a person, not in the feed, and LinkedIn charges per send rather than per impression.
One message, one button.
The format that used to be called Sponsored InMail, renamed in 2020. One block of copy and a single call-to-action button that opens a Lead Gen Form or a web page. The API still labels it SPONSORED_INMAIL.
A chat with buttons.
A first message with two or more reply buttons, each leading to a further message or an action. It lets you sort people by answer, and it is also where most accounts build the over-engineered decision trees this playbook argues against.
| Same advertiser, both formats | Conversation vs message ad | Read it as |
|---|---|---|
| Open rate | −20% | Fewer people open the chat format. Lower in 43 of 53 accounts. |
| Form completion | +21% | The people who click through a button finish the form more often. |
| Cost per lead | +36% ns | A tie: the interval runs from −16% to +158%. |
| Cross-panel cost per lead | $347 vs $111 | Different advertisers run each format. Directional only. |
Paired within 53 accounts running both formats, ★★. Kiin Labs, Conversation Ads Benchmarks 2026, chapter 03. The format history and setup are on conversation ads vs Sponsored InMail.
Kiin runs both routes. They answer different questions.
A conversation ad has to send the person somewhere. Either they stay on LinkedIn and fill a Lead Gen Form, or they leave for your website or booking page and your own conversion tracking records what they did.
- Lead generation objectiveThe button opens a LinkedIn Lead Gen Form
- Pre-filled form, three fieldsName, work email, company from the profile
- The lead stays in LinkedInSynced to the CRM with the campaign name
- Instant follow-upEmail with a booking link the moment it lands
- Website conversions objectiveThe button opens your page, not a form
- Booking page or landing pageCalendly, or a page with one form
- Insight Tag records the outcomeA booked meeting counts as the conversion
- The meeting is already bookedSales confirms, nobody chases
Route A keeps the data in LinkedIn
The form is pre-filled from the member's profile, so finishing it is one tap. That is why 41% of people who open a conversation ad form submit it, against about 5% of landing page clicks converting at the median account. It is the default for anything that is not a meeting, for cold audiences, and for accounts without solid website conversion tracking. LinkedIn reports the lead directly, so cost per lead is visible in Campaign Manager.
Route B judges the ad on meetings
The Website Conversions objective sends the click to your site and optimises toward a conversion you define, which for Kiin is usually a booked call on a calendar page. The result lives in your Insight Tag or conversions API data, not as a LinkedIn lead, so it reads as zero leads in Campaign Manager. Message-ad clicks are expensive as traffic, $40.34 a landing page click against $13.83 for sponsored content in the same accounts, but 30.6% of them converted against 3.0% (20 accounts, directional). You buy fewer visitors who mean it.
How to run LinkedIn conversation ads, step by step
These are the conversation ad best practices Kiin uses on every account, in the order we set a campaign up. Each step says what the data shows and what we do about it.
Pick the route before you write a word
The route decides the objective, the button, the copy and the number you will judge it on, so it comes first. Four situations cover most accounts.
| If | Then | Judge it on |
|---|---|---|
| The offer is a meeting, the audience is a warm retargeting pool, and sales calls back inside the hour | Route B: Website Conversions objective, button straight to a booking page | Cost per booked meeting and meetings per 1,000 sends |
| The offer is softer than a meeting: a report, a benchmark, an audit, an event | Route A: Lead generation objective, Lead Gen Form, three fields | Cost per lead, then stage two in the CRM |
| The audience is cold or an uploaded account list | Route A with a soft ask, and a calendar link in the follow-up | Cost per send and form opens per open |
| You have no conversion tracking you trust | Route A until you do | Cost per lead |
Decision rules from the Kiin playbook in Report No. 2, chapter 18: the no-form calendar version only for a meeting offer, a fast sales team and a retargeting audience.
Audience: build the retargeting pool, then message it
The biggest response gap in the data is who receives the message. Inside the same account, a retargeting audience (website visitors, video viewers, people who engaged with your ads) produced 71% more leads per send and 18% more opens than cold attribute targeting, at the same cost per send. Against an uploaded contact or company list it was 36% cheaper per lead.
The list result is the one that changes plans. Most teams treat their target account list as their warmest audience. In the paired data it behaved like cold and cost 21% more per send. A list is a set of people you would like to be warm, so Kiin runs it as a cold campaign with a cold target.
- Warm first. No retargeting pool of a few thousand people yet? Build it with Thought Leader Ads and video before switching the messages on.
- Cold is a separate campaign. 15,000 people minimum, 50,000 better. Bigger audiences cost 24% less per send in the same account, a cheaper send rather than a guaranteed cheaper lead.
- Audience Expansion off. It widens the pool past the people you chose. Keep LinkedIn Audience Network off on every feed campaign that feeds the pool.
- Seniority filters are a qualification choice: senior-only cost 27% more per lead (ns) in the same accounts, with 5% fewer opens.
Retargeting vs cold: lead rate +71% [+15%, +116%], opens +18% [+11%, +26%], n = 49 accounts. Cost per lead vs cold −18% [−38%, +9%], n = 37, directional: the interval spans zero. Vs an uploaded list: −36% [−49%, −11%], n = 32. ★★
The full audience chapter: retargeting vs cold vs uploaded lists.
Sender: a real person, and more than one when volume runs out
A sponsored message arrives looking like a note from whoever you name as the sender, with their photo and headline. Kiin sends from a person, usually the founder or the account executive who will take the call, never from the company page, because the message only works if it reads like one human writing to another.
Be clear about the evidence. The Kiin Labs panel could not measure the sender effect: sender and copy were not synced for the study period, so this step is practitioner judgement, informed by the Thought Leader Ads research where the author matters more than the copy.
LinkedIn limits how often one member can receive sponsored messages, about one per 30 days. In the Lumi AI account that limit applied per sender, so adding a second sender could double the volume a small retargeting pool can take. When a warm campaign stops spending, check the cap before you raise the bid.
The message: LinkedIn conversation ad examples that work, and one that does not
One paragraph. Proof first, then what you do in a sentence, then the ask. Below are three examples written for Kiin's own offers, so nothing in them is invented about a client.
Hi %FIRSTNAME%,
You've read a few of our LinkedIn Ads reports this month, so here is the useful version: 30 minutes where we put your account next to the 1,000+ others in our benchmark and show you the three settings costing you most.
No deck. Pick any slot this week.
Hi %FIRSTNAME%, quick one.
We studied $7.7M of LinkedIn conversation ad spend across 263 accounts. The median lead cost $200. The cheapest tenth paid $32, and two settings explain most of the gap.
Want the report? It's free and I'll send it straight over.
Hi %FIRSTNAME%! 👋 Are you struggling to get results from LinkedIn Ads? You're not alone! Let me know what you'd like to explore:
Proof, then the offer, then one ask
Two or three companies you have done the thing for and one number, a sentence on what you do, then the ask with its time cost: 30 minutes, this week. When openers do not click, rewrite the first two lines and the button label before anything else.
Test dropping it
On Storysnap, the variant with no subject line lifted open rate 12 points, from 37 to 38% to 49 to 52%, across both brands. Across the panel, though, open rate explains only 2% of cost per lead, so treat it as hygiene, not the lever.
Send all seven days
Opens are logged when they happen, so Monday reads 109 and Saturday 88 against a weekday of 100, but leads per send hold at 0.16 to 0.17% every day of send. Cheapest day is account-specific: Storysnap's Thursday leads cost $149, Saturday $301.
One clear call to action, not a decision tree
Every button you add is a decision the reader has to make before they do the thing you wanted. The data gives the branching format no credit for that work: in the 53 accounts that ran both, multi-button conversation ads were opened 20% less than single-message ads and came out level on cost per lead, because the extra form completion they earned was cancelled out by the people who never opened.
So Kiin writes one ask with one button. If the sales team genuinely needs leads sorted, a second button is the most we use. The benchmark report leaves the door open for buttons when there are two or three distinct offers for one audience. A tree of five branches is never that.
In the accounts Kiin runs, a message ad whose one button goes straight to a Calendly booking page gets really good results on a warm audience. The reason is in the Lumi AI case study: form leads went up 30% while bookings per lead fell from about 60% in May to 23% in August. People closed the form meaning to book later, and never did. Sending them to the calendar removes the step where intent leaks.
A soft ask and a calendar link are judged on different numbers
The panel counts Lead Gen Form submissions. On that scale the form wins for anything softer than a meeting: 41% of form opens submit, a landing page converts about 5% of its clicks, and the lead costs $200 at the median. That is why Example B asks for a report, not a call.
A calendar campaign records no LinkedIn leads, so it has to be read on meetings in your own tracking. Booking campaigns in the panel run almost entirely on lists and retargeting pools. Nobody books cold.
Warm pool, meeting offer, fast sales team: one button to the calendar. Cold audience or a softer offer: a soft ask into the form, and the calendar link goes in the follow-up within minutes.
Bidding and budget: start at LinkedIn's minimum
For years Kiin told clients to bid high on sponsored messaging to win the inbox slot. We measured it and reversed the advice. Comparing each account's highest-bid campaign with its lowest, across 119 accounts, the higher bid paid 80% more per send and 44% more per lead for exactly the same open rate. The median campaign pays 62% of its bid, and the cheapest ten accounts in the panel bid $0.35 a send.
- Start at LinkedIn's minimum bid, not the recommended bid.
- If sends have not flowed after 48 hours, raise it by the smallest increment that gets them moving.
- Widen the audience before you raise the bid.
- Refresh the message when cost per send is 15% above launch. Open rate will not tell you: it holds for eight weeks while cost per send drifts up about 13% by week six.
Budget maths. At the median cost per send of $0.42, 10,000 sends cost about $4,200. At the median lead rate of 0.09%, those sends return about nine leads. A warm pool beats that; a cold list rarely does. 30% of accounts in the panel got zero leads in twelve months, $1.16M between them.
Cost per send +80% [+56%, +110%] and cost per open +77% [+47%, +108%], n = 119 accounts; cost per lead +44% [+8%, +64%], n = 64; open rate 0% [−3%, +4%]. Bids at least 1.5x apart. ★★★
The bid bands and the full reversal: how to bid on LinkedIn conversation ads. Cost per send by format, audience and region: LinkedIn InMail ads cost.
Follow-up and handover: catch the lead while it is still on LinkedIn
Route A only works if the gap between form and meeting is minutes, not days. This is the follow-up stack Kiin built on the Lumi AI account after bookings per lead slid from about 60% to 23%.
Instant email
On form submit: “If you haven't already, here's the link to book.”
Active list for the BDR
Source is LinkedIn paid social and status is not Connected: straight into the BDR queue.
LinkedIn sequence
Unbooked leads get a connection request and a short message sequence.
“Did not book”
The no-show sequence also fires for leads who never booked a slot.
Two more habits close the loop. If you stay on Route A for a meeting offer, the Lead Gen Form's Book an Appointment step puts a Calendly picker inside the form itself. And every lead goes into the CRM with the campaign name attached, judged at stage two and stage three, not at the lead count. The flows we run are written up in how to follow up LinkedIn ad leads.
Read the leading indicators in order
Cost per lead arrives last and tells you nothing about why. The indicators before it do, if you read them in the order the person moves.
| Indicator, in order | Median | Good | A weak reading points to |
|---|---|---|---|
| Open rate | 42.6% | 48.8% | Under 37%: the sender, the audience or the region. Check whether weekend sends opened on Monday are dragging the reading first. |
| Form opens per open | about 1% pooled | 1.97 per 100 | Opens fine, no clicks: the offer or the first two lines. Rewrite the copy and the button. |
| Form completion | 41% | 53% | Under 29%: the form. Too many fields or a custom question. Cut to three fields. |
| Lead rate (leads per send) | 0.09% | 0.22% | The product of the three above. Low with fine parts usually means a small or cold audience. |
| Cost per send | $0.42 | $0.23 | Above $0.69: the bid, or an audience too small for the auction. |
| Cost per lead | $200 | $85 | The outcome. Bottom quarter pays $495. |
| Route B: landing page clicks per open | 1.1% | 2.7% | The same signal as form opens per open, for the off-platform route. |
| Route B: bookings and cost per booked meeting | withheld | withheld | Fewer than 10 accounts record bookings, so Kiin Labs does not publish a benchmark; read your own tracking. |
Good = top quarter of accounts; on the Route B booking rows, the retargeting pools and the best accounts. Per-account medians and quartiles, 242 accounts with 1,000+ sends; form completion on 145 accounts, cost per lead on 149. Form opens per open: pooled about 1%, cheapest quarter of accounts 1.97 per 100 opens vs 0.57 in the dearest. Route B: 104 no-form accounts; booking figures withheld under the 10-account floor.

LinkedIn conversation ads: frequently asked questions
What are LinkedIn conversation ads?
LinkedIn conversation ads are sponsored messages delivered to a member's LinkedIn inbox, with a first message and two or more reply buttons that lead to further messages, a Lead Gen Form or a web page. Together with single-button message ads they make up LinkedIn Sponsored Messaging. Across 263 advertiser accounts the median account pays $200 per lead at a 42.6% open rate (Kiin Labs, 2026).
What is the difference between conversation ads and message ads?
A message ad is one message with one call-to-action button; a conversation ad is a multi-step chat with two or more buttons. Inside the same account, conversation ads are opened 20% less, complete the form 21% more often, and tie on cost per lead (53 accounts, Kiin Labs 2026). Pick the format by whether the offer needs sorting, not by price.
What is a good open rate for LinkedIn conversation ads?
The median account opens 42.6% of sends; 48.8% or more is top quarter and 53.9% top tenth. Under 37% points to the sender, the audience or the region rather than the copy. Open rate explains only 2% of the variation in cost per lead, so it is a hygiene check, not the lever.
How much do LinkedIn conversation ads cost per send and per lead?
The median account pays $0.42 per send and $200 per lead, with cost per lead running from $32 at the 10th percentile to $1,005 at the 90th. The median account converts 0.09% of sends into leads, about nine leads per 10,000 messages. Bidding LinkedIn's minimum and messaging a retargeting pool are the two settings that pull cost down most.
Should a conversation ad use a Lead Gen Form or a landing page?
Use the Lead Gen Form for anything softer than a meeting and for cold audiences: 41% of form opens submit, against about 5% of landing page clicks converting at the median account. Send people off LinkedIn with the Website Conversions objective when the offer is a meeting, the audience is warm and your conversion tracking records the booking.
Can you link a LinkedIn conversation ad straight to Calendly?
Yes, two ways. The button can open a Calendly booking page under the Website Conversions objective, tracked as a conversion, or a Lead Gen Form can include LinkedIn's Book an Appointment step with a Calendly picker inside the form. Booking campaigns work on warm audiences: in the panel they run almost entirely on lists and retargeting pools.
How many buttons should a LinkedIn conversation ad have?
One clear ask, and two buttons at most when sales needs leads sorted. Multi-button conversation ads are opened 20% less than single-message ads in the same account and do not get cheaper leads for it. A branching tree of four or five buttons adds messages to write and buries the ask, so Kiin does not run them.
How often can you send a conversation ad to the same person?
LinkedIn limits how often one member receives sponsored messages, about once every 30 days, so the cap paces the campaign for you. In Kiin's Lumi AI account the cap applied per sender, so a second sender doubled the volume a small retargeting pool could take. Open rate does not fatigue: it held for eight weeks after launch in the panel data.
Are conversation ads the same as Sponsored InMail?
No. Sponsored InMail was renamed message ads in 2020 and is the single-button format. Conversation ads are the multi-step version with two or more buttons, added the same year. Both sit under Sponsored Messaging and are charged per send. In the panel, message ads run a 45.4% campaign-median open rate and conversation ads 38.1%.
We build the pool, the message and the follow-up behind it.
Kiin runs LinkedIn conversation ads as part of its managed LinkedIn Ads service for sales-led B2B SaaS, on a flat fee from $2,500 a month with ad spend paid separately, and builds the retargeting pool, the sender, the message and the handover to sales.
