Sponsored messages on LinkedIn are ads that are sent directly to the inboxes of selected users on the platform. They appear as one-on-one conversations and allow brands and agencies to initiate personalized exchanges with high-level professionals, decision-makers, and specific B2B audiences. LinkedIn offers two formats: Message Ads, which feature a single call to action, and Conversation Ads, which feature interactive multi-step response flows.
What are sponsored posts on LinkedIn, and what are they used for?
Unlike feed ads, sponsored messages do not compete with organic content or other posts. The message goes directly to the recipient’s inbox, which significantly increases the open rate compared to other advertising formats on the platform.
This format is particularly useful for digital marketing agencies that work with clients pursuing B2B goals, as it allows for highly precise targeting and the ability to personalize content at scale.
The most common use cases include:
- Generating qualified leads for high-value products or services
- Invitations to events, webinars, or live demonstrations
- Distribution of downloadable resources such as guides, reports, or case studies
- Presentation of solutions to audiences segmented by job title or industry
- Reaching out to contacts who have previously engaged with the brand
Types of sponsored posts on LinkedIn
Message Ads
Message Ads are the most straightforward format. They consist of a text message with a single call-to-action button. They are ideal when the objective is clear and the path to conversion does not require multiple intermediate steps.
They are recommended for specific actions such as downloading a resource, registering for an event, or requesting a demo.
Conversation Ads
Conversation Ads allow you to create interactive flows. The recipient receives an initial message and can choose from several responses, each with its own path and CTA. This format is best suited for cold audiences or when you want to guide users toward different solutions based on their profile or needs.
Comparison of formats
| Criterion | Message Ads | Conversation Ads |
|---|---|---|
| Message Structure | Linear, a single CTA | Branched, multiple CTAs |
| Level of customization | Medium | High |
| Ideal for | Straightforward and simple offers | Cold audiences or complex proposals |
| Setup time | Bass | Mid-high |
| Cost per estimated result | Varies by industry | Varies by industry |
| A/B testing capability | Yes | Yes |
Audience segmentation and configuration
Targeting is one of the key advantages LinkedIn Ads has over other platforms. For sponsored posts, precise targeting not only improves the relevance of the message but also reduces the cost per result by eliminating unnecessary impressions or deliveries.
Available segmentation criteria
- Job title and role: This allows you to target specific roles such as marketing directors, purchasing managers, or CTOs.
- Business sector: useful for vertical campaigns targeting specific industries.
- Company size: This allows for a distinction between small and medium-sized enterprises (SMEs), medium-sized companies, and large corporations.
- Length of service: relevant when the message needs to be tailored to the recipient's level of experience.
- Professional skills and interests: These complement job-based segmentation with more behavior-based criteria.
- Retargeting audiences: users who have visited the website or interacted with the brand’s previous content.
A best practice is to create saved audiences so you can reuse them in future campaigns. This reduces setup time for accounts with multiple active campaigns, something agencies particularly value when managing several clients at the same time.
Step-by-Step Guide to Setting Up Sponsored Posts on LinkedIn
- Go to LinkedIn Campaign Manager. Log in to your advertising account and select the appropriate client account.
- Create a new campaign. Click “Create Campaign” and give it a descriptive name to make it easier to organize and report on later.
- Select your campaign goal. Choose between lead generation, website conversions, or brand awareness, depending on the outcome you want to measure.
- Define the target audience. Apply the relevant targeting filters for the client. Save the audience if you plan to reuse it.
- Choose the ad format. Select "Message Ad" or "Conversation Ad" based on the complexity of the message and the audience's engagement level.
- Write the message. Use dynamic variables to personalize the recipient's name. Be direct in the first few lines: state who is sending the message and what benefit it offers. End with a specific call to action.
- Include a real sender photo. Use a photo of a person, not a logo. This significantly improves the open rate.
- Set your budget and bid. LinkedIn uses the cost-per-send (CPS) model. Set your daily or total budget and adjust your bid based on the client’s performance goals.
- Enable conversion tracking. Connect the LinkedIn pixel or the native Lead Gen form to track results accurately.
- Launch the campaign and establish a review schedule. Review key metrics within the first three to five days to identify opportunities for quick adjustments.
Best practices for optimizing performance
Composing the message
- Keep your message brief. Messages under 500 characters tend to generate higher open rates.
- Avoid an aggressive sales pitch. LinkedIn penalizes messages that look like spam, and users respond better to a consultative approach.
- Include only one call to action per message. Including multiple options in a Message Ad can be confusing.
- Use dynamic variables such as {{firstName}} to customize content without increasing production time.
Key metrics to monitor
- Open rate: indicates the percentage of recipients who opened the message. A healthy rate varies by industry, but rates above 30% are considered competitive.
- Click-through rate (CTR): measures how many users who opened the message clicked on the CTA.
- Cost per lead (CPL): the key metric that determines the campaign's cost-effectiveness.
- Post-click conversion rate: measures what happens after the click, on the landing page or the native form.
For agencies that manage multiple clients with active campaigns on LinkedIn and other platforms, manually consolidating these metrics into individual reports is extremely time-consuming. Tools like Master Metrics allow you to centralize data from LinkedIn Ads, Meta Ads, Google Ads, and other sources into a single automated dashboard, making it easier to review performance regularly without any additional manual effort.

Frequently Asked Questions About Sponsored Posts on LinkedIn
What is the difference between Message Ads and Conversation Ads?
Message Ads are linear messages with a single call-to-action button. Conversation Ads offer an interactive flow where the recipient can choose from several responses, each with its own CTA. Message Ads are best suited for direct, simple offers; Conversation Ads work best for cold audiences or when the qualification process requires multiple steps.
How much does a sponsored post campaign on LinkedIn cost?
LinkedIn charges on a cost-per-delivery (CPD) basis, meaning you pay for each message delivered to the recipient. The cost varies significantly depending on the industry, the competitiveness of the audience, and the bid you set. There is no fixed rate; agencies typically set daily test budgets to gauge the cost before scaling up their investment.
How often can a single user receive sponsored messages?
LinkedIn enforces a frequency cap to protect the user experience. Each member can only receive one sponsored message from the same advertising account every 30 days. This limit is automatic and cannot be changed, so it’s important that the message is relevant from the very first send.
Can lead generation forms be used in sponsored posts?
Yes. LinkedIn allows you to embed native lead generation forms directly into Message Ads and Conversation Ads. These forms are filled out within the platform without redirecting the user to an external site, which reduces friction and can increase the conversion rate. The captured data can be downloaded from Campaign Manager or integrated with a CRM.
Which metrics should I prioritize when evaluating a campaign's performance?
The most important metrics are the open rate, the CTR (click-through rate on opened messages), and the cost per lead. The open rate indicates whether the subject line and sender generated interest. The CTR shows whether the message content was compelling enough. The CPL determines whether the campaign is profitable in relation to the client’s objectives.
Do sponsored posts work for any type of business?
This format is particularly effective for B2B businesses offering products or services with long sales cycles or high-ticket prices. It works well in sectors such as technology, consulting, financial services, professional training, and enterprise software. For B2C businesses dealing with low-ticket items or impulse purchases, other LinkedIn ad formats or platforms like Meta Ads typically offer a better return on investment.
How can I improve the open rate for my sponsored messages?
Three factors directly influence the open rate: the sender, the subject line, and the relevance to the audience. Using a real photo of a person (not a logo) as the sender’s image enhances the perception of authenticity. A short, specific subject line—free of generic or sales-y language—generates more curiosity. Finally, the more precise the segmentation, the more relevant the message will be to the recipient.
How does Master Metrics help manage sponsored post campaigns on LinkedIn?
Master Metrics consolidates data from LinkedIn Ads along with data from other advertising platforms—such as Meta Ads, Google Ads, and TikTok Ads—into an automated dashboard. This allows agencies to monitor the performance of sponsored post campaigns without having to create manual reports for each client. With all the information in one place, it’s easier to identify opportunities for optimization and present results in a clear and professional manner.
Conclusion
Sponsored posts on LinkedIn are one of the most effective tools for reaching B2B audiences in a direct and personalized way. Setting up a campaign correctly—from choosing the format to crafting the message and targeting the audience—makes the difference between a campaign that generates qualified leads and one that burns through the budget without measurable results.
For agencies that manage multiple clients with active LinkedIn campaigns, regularly reviewing metrics such as open rate, CTR, and CPL is essential for making informed decisions. Automating this process with a tool like Master Metrics eliminates the manual work of consolidating data and allows you to focus on strategy and actual campaign optimization.
Implementing best practices from the start—short messages, precise targeting, senders with real photos, and clear calls to action—is the foundation for building sponsored message campaigns that deliver consistent results for any agency’s clients.
