What are LinkedIn Message Ads?

LinkedIn Message Ads (formerly Sponsored InMail) are a LinkedIn advertising format that delivers personalized messages directly to the LinkedIn inboxes of targeted members, appearing as a sponsored message from a page rather than a personal connection. Recipients are targeted by the same professional attributes available in LinkedIn Ads targeting: job title, company, seniority, industry, and skills. Message Ads include a message body (up to 500 characters), a subject line (up to 60 characters), and a single CTA button that links to a landing page or lead gen form. Members only receive a Message Ad if they are active on LinkedIn within the delivery window.

LinkedIn Message Ads vs Conversation Ads

Message Ads deliver a single message with one CTA. Conversation Ads (the newer format) deliver an interactive message with multiple CTA options allowing recipients to select different paths (Learn more about feature A, See pricing, Request a demo), creating a branching message flow. Conversation Ads typically have higher engagement rates and better lead quality than linear Message Ads because recipients self-select their interest area, providing implicit intent data. For most SaaS ABM use cases, Conversation Ads are preferred over Message Ads.

Frequently Asked Questions

What is a good open rate for LinkedIn Message Ads?

LinkedIn Message Ads open rates typically range from 30-50%, significantly higher than email open rates. However, open rates for Message Ads are measured differently than email (LinkedIn counts views in the message thread, not just opens of the notification). Click-through rates from opens are typically 3-10%. The most meaningful metric is lead or conversion rate per message delivered, not just open rate. Well-targeted Message Ads with compelling offers and clear value propositions achieve 2-5% lead conversion rates (as a percentage of messages delivered), which compares favorably to cold email sequences for the same target personas.

What offers work best in LinkedIn Message Ads for SaaS?

High-converting LinkedIn Message Ad offers: specific content assets (research reports, benchmarking studies, playbooks) that address a genuine challenge for the target persona, event invitations (executive dinners, webinars) for accounts in ABM target list, free trial or freemium signup offers for self-serve products, and product demo invitations with a clear outcome promise (See how [Company X] reduced their sales cycle by 40% in one call). Generic book a demo messages without specific value framing perform significantly below average. The message should demonstrate that you understand the recipient specific professional challenge and offer something that addresses it directly.
