LinkedIn conversation ads: setup and costs

LinkedIn conversation ads land in a member's LinkedIn inbox and let them choose a path with buttons, like a short branching chat. You pay per send, typically somewhere around $0.50 to $1 per message. Two things matter before you build one: in the EEA and Switzerland they only reach members who have opted in to sponsored messages, and every conversation ad now carries a required "Not interested" button.

TL;DR

• Conversation ads are sponsored messages with multiple buttons. Message ads have a single button.

• Pricing is cost per send. Benchmarks put most sends around $0.50 to $1.

• In the EEA and Switzerland, only members who opted in receive sponsored messages.

• LinkedIn recommends two to three messages with at least two buttons each.

Conversation ads vs message ads

Both formats sit under LinkedIn's Sponsored Messaging. Message ads deliver one message with a single call-to-action button. Conversation ads add multiple buttons that branch into different paths (LinkedIn).

• Message ads: best for one clear invitation, such as an event or a demo for engaged accounts.

• Conversation ads: best when people need to choose, such as "send me the guide", "book a call" or "not now".

Some practitioners report message ads currently opening better than conversation ads for the same audience, so test both rather than assuming the interactive format wins.

What it costs

Sponsored Messaging uses a cost-per-send model: you pay each time a message is delivered.

• One ABM benchmark report puts message ad sends at about $0.50 to $1.00 for targeted audiences (ZenABM).

• A 2026 benchmark roundup, based on agency data it labels as directional, puts conversation ads near $0.92 per send (The Ad Spend).

Members can only receive a limited number of sponsored messages, so each send should carry a strong offer. The same ZenABM guide notes a 45-day frequency cap for message ads.

The maths that matters is cost per lead: divide your cost per send by your open rate, click rate and conversion rate. A cheap send with a weak offer is still an expensive lead.

The EU rule you need to know

LinkedIn supports EEA and Switzerland targeting for conversation and message ads, but only members in those countries who opted in to see Sponsored Messaging ads will receive them (LinkedIn Help). Expect much smaller delivery for European audiences, and plan Sponsored Content or Thought Leader Ads alongside.

How to build a conversation ad

LinkedIn's own guidance is to share information in bits rather than in bulk, with two to three messages and at least two buttons people can choose from (LinkedIn).

1. Intro message: short, personal, one question. Add two or three buttons, such as "Send me the benchmarks", "Book 15 minutes" and the required "Not interested".

2. Branch messages: one per button, each delivering exactly what was promised.

3. Final step: a Lead Gen Form or a link, with one clear action.

The "Not interested" button is required and added automatically to the intro message of new or edited conversation ads (LinkedIn Help). For message ads, the subject line can be up to 60 characters (LinkedIn Help).

When to use conversation ads

• Event and webinar invitations for a defined account list.

• Content offers with a choice of formats.

• Re-engaging warm accounts that visited pricing or attended an event.

Avoid them for cold, broad audiences. They feel intrusive when the offer isn't relevant.
