LinkedIn Message Ads are a Sponsored Messaging format that sends a single message, with one call-to-action button, to a member's LinkedIn inbox from a real person's profile. They're also called LinkedIn sponsored messages. Because the message comes from a named person rather than a company logo, it reads like a direct note.
A Message Ad is delivered only when the member is active on LinkedIn, so it arrives while they're on the platform instead of sitting unread in an inbox they rarely check. Every message is sent from a named sender, usually someone at your company whose role fits the audience. The message has one button, which leads to a landing page or opens a LinkedIn Lead Gen Form. LinkedIn also caps how often the same member can receive Message Ads, which third-party guides put at roughly once every 45 days per advertiser.
Message Ads used to be called Sponsored InMail, and people still search for them as sponsored inmail, LinkedIn sponsored inmail, and LinkedIn inmail ads. All of these refer to the same paid format. It's different from regular InMail, the messaging credit that comes with a paid Premium subscription and lets you message people outside your network one at a time.
Message Ads are billed per send, meaning you pay each time a message is delivered, not per click or per impression. Third-party benchmarks give a rough range: ZenABM puts cost per send at $0.50 to $1.00 for account-based campaigns, and Stackmatix puts it at $0.80 to $1.20, rising for C-suite audiences. A send isn't an open, so your real cost per opened message will be higher than the cost per send.
Message Ads win when there's one clear ask. An event registration, a report download, or a meeting request from a named sender all work better as one short message with one button, because there's no decision for the reader to make.
LinkedIn Conversation Ads win when the reader needs to choose a path, such as picking between a demo and a case study, or routing different roles to different offers. If your message needs more than one button, it's a Conversation Ad.
LinkedIn restricts delivery of Sponsored Messaging in some regions, including parts of Europe. Check LinkedIn's current delivery rules for the countries you're targeting before building a Message Ads campaign, or the campaign may launch and never reach part of your audience.

They're billed per send. Third-party benchmarks put typical cost per send at $0.50 to $1.20, with senior and C-suite audiences at the higher end.
Yes. LinkedIn renamed Sponsored InMail to Message Ads, and both names refer to the same paid inbox format.
They work best for one clear ask sent to a warm audience, like an event invite to past website visitors. They perform poorly as a cold pitch to people who have never heard of you.
LinkedIn caps delivery per member, and third-party guides put the limit at roughly one Message Ad per advertiser every 45 days.
Usually, yes. A Lead Gen Form lets the reader respond without leaving LinkedIn, which removes the landing page step where many leads drop off.
LinkedIn Sponsored Content is the feed-based ad family, separate from Sponsored Messaging. LinkedIn Matched Audiences is where you build the retargeted and uploaded lists this format performs best with.
