LinkedIn Mass Messaging Guide: How to Increase Sales Without Getting Banned in 2026

TL;DR:

LinkedIn mass messaging can help you expand your professional network, promote your business, and start meaningful conversations at scale.

Here is a quick summary of key tips to help you send bulk messages on LinkedIn safely and strategically.

Stay safe: Follow SSI-based daily LinkedIn messaging limits—start with 10 actions for SSI below 20, gradually increase to 30-40 for SSI above 40. Use automation tools like Snov.io with warm-up modes, smart scheduling, and human-like delays to avoid account restrictions.

Get results: Personalize every DM using segmentation and dynamic content. Aim for 20-30% acceptance rates by leading with value rather than sales pitches. Respond within 24 hours to build sender reputation and strengthen relationships.

LinkedIn is ideal for B2B professionals to find new business partners and clients. It has even become a preferred channel for marketers engaging with their customers.

But how do you reach all the potential clients? LinkedIn posts and ads can help boost your brand awareness, but if conversions are low, sending mass LinkedIn messages can expand your reach.

In this article, we’ll explain how using this tactic can boost outreach and ultimately increase sales on social media.

LinkedIn mass messaging: what it means

LinkedIn mass messaging is the practice of sending the same message to multiple first-degree connections or prospects at once to save time, typically for marketing, networking, or event invitations.

Digital marketers and sales reps successfully leverage mass messaging for networking, lead generation, and sales. But taking advantage of it is not as straightforward as it might seem.

The platform imposes certain restrictions on DMs to prevent spam and maintain user engagement. Meaning, it must be used carefully and thoughtfully.

LinkedIn offers different mass messaging approaches, each serving distinct purposes in your outreach strategy:

LinkedIn group messages (chats)

Group chats are multi-person conversations where all participants share the same message thread and can see each other’s responses.

To create a group chat, you need to add multiple recipients (up to 50 members) in the LinkedIn composer. They will all have access to the complete conversation history.

✅ Do: Use LinkedIn group messages for team discussions, project collaboration, and multi-stakeholder conversations

❌ Don’t: Use group chats for LinkedIn mass messaging; every member sees all messages, which can be viewed as impersonal and unprofessional

Individual direct messages

Individual DMs are private, one-on-one conversations between you and a single recipient. These messages come in two forms, depending on your connection level:

• Messages to 1st-degree connections

Once connected, you can DM your 1st-degree connections directly from the LinkedIn Messaging page, conversation window, or their profile.

• InMail messages (For non-connections)

To privately DM someone outside your network, you’ll need InMails. This feature requires a Premium subscription along with LinkedIn InMail credits.

Note that some members opt out of receiving InMail in their privacy preferences. In those cases, we recommend sending connection requests instead.

How many messages can you send on LinkedIn in a day?

LinkedIn limits the number of DMs a user can send for spam prevention. These limitations aim at improving user experience. But they can be a pain in the neck for sales as well as marketing professionals.

The volume of daily DMs one can send depends on their subscription type and Social Selling Index (SSI). While the platform doesn’t specify the exact number, users with higher SSI can send more DMs without triggering the algorithm and risking account restrictions.

LinkedIn InMail credits

Each Premium account type gets a monthly amount of InMail credits based on the subscription plan. Unused ones build up, but only to a certain limit.

Check out this table for more details:

Also, InMail credits renew on the first day of your billing cycle. Plus, any InMail that gets a response (accepted or declined) is added back to your account within 90 days.

DM/connection/request LinkedIn safety limits

Your SSI (Social Selling Index) is a reflection of how strong your presence and engagement are on LinkedIn. Based on that score, here are Snov.io’s recommended safe activity levels, which are essential for avoiding platform warnings and keeping your outreach effective:

• SSI below 20: Limit yourself to 10 actions per day
• SSI improving: Gradually increase by 5-10 actions per week as your score rises
• SSI 40 or higher: You can safely perform 30-40 actions daily in each category

Remember that each limit applies per action type, including profile views, connection requests, and DMs.

Just remember that these are Snov.io expert recommendations, since the platform doesn’t openly disclose official LinkedIn messaging limits.

How to mass message on LinkedIn

Users can send mass messages on LinkedIn manually or with the help of automation tools.

The first approach works well for people who don’t have to send bulk messages often. Someone who just wants to send a funny meme to their connections once in a while doesn’t need automation.

On the other hand, someone who must reach out to other users daily should invest in LinkedIn automation software. It significantly speeds up mass messaging and helps ensure brand consistency throughout all interactions.

You can alternate between approaches depending on your goals. Still, it’s worth knowing how to set up an outreach campaign both with and without LinkedIn automation software.

Without LinkedIn mass messaging tools

Sending messages on LinkedIn is quite straightforward. If you only need to message a couple of users, messaging them manually one by one is the easiest way to go.

1. Find the LinkedIn Messaging tab at the top of your screen.

Alternatively, you can find this tab at the bottom right corner of your LinkedIn profile.

2. Click on the New Message icon.

3. Type in a recipient name or choose one from the suggestions below.

4. Write your message and hit “Send.”

5. Repeat the process for each of the recipients on your list.

❗️Important: Adding multiple recipients at once creates a group chat, not individual DMs. Before doing so, check this table to see if a LinkedIn group messsages aligns with your goals:

Follow these recommendations for strategic communication.

With Snov.io LinkedIn bulk messaging tool

Sending messages one by one is time-consuming. You can streamline this process by using our LinkedIn automation tool. To do this, you’ll have to create a Snov.io account and connect your LinkedIn account to it.

Before you can start your social media outreach campaign, you’ll need to gather a list of prospects. The quickest way is to use the Snov.io LinkedIn Email Finder. It’s a Chrome extension that allows you to save leads from personal, company, as well as search results pages on LinkedIn.

This extension scrapes leads’ contact information, including email addresses and LinkedIn page URLs, and adds it to your prospect list. It also acquires other public data from leads’ profiles, which can later be used to personalize mass messages.

You can also take advantage of Snov.io’s LinkedIn Search feature. Just drop in your LinkedIn search results URL or upload profile links, and the tool will add the contacts straight to your prospect list.

Once you have a list of prospects you’d like to mass message, it’s time to set up the campaign.

Step 1. Go to the Campaigns tab in your Snov.io account and click “New campaign” on the left-side panel.

Then, you’ll be able to create a new campaign from scratch or choose a pre-made template. While templates are invaluable for effective outreach, today, we’ll explore how to start from scratch.

Step 2. Select the LinkedIn element on the right-side panel.

Step 3. Choose an action you’d like to start your sequence with. If you’ve already connected with users on your prospect list, simply start with a message.

Otherwise, send a connection request first. You might also want to add other LinkedIn touches to attract your recipients’ attention and build trust before contacting them.

Step 4. Configure the next step depending on whether you’ve connected with your lead or not. Remember, you can only send regular DMs to your connections. To reach other users, you can use InMails if you have a paid account.

You can set conditions and filter your sequences by connection level, so your messages and InMails are automatically sent only to 1st-, 2nd-, or 3rd-degree connections for more targeted outreach.

Step 5. After you’re satisfied with your sequence, click Next at the bottom of the page.

Now, choose a list of prospects you’re going to mass message on LinkedIn and fill out other campaign settings. Click Next.

Step 6. Select the LinkedIn account you want to send DM from. Then, configure other sending options according to your goals.

Step 7. Review your campaign before launching. Don’t worry; our smart outreach automation solution will notify you of any missing information or incomplete steps.

Step 8. Run your campaign and start receiving responses from your leads.

📍Why opt for Snov.io and not other tools?

LinkedIn mass messaging can indeed be risky, especially with tools that lack strong safety features. But Snov.io places a strong emphasis on account protection while simultaneously delivering powerful automation.

The pros and cons of sending mass messages on LinkedIn

It’s true that mass outreach is a valuable tactic for marketing and sales professionals, as well as event organizers. At the same time, it comes with a set of challenges. After all, users are professionals who can easily spot a LinkedIn mass message.

So, before starting a mass campaign, consider the potential benefits as well as drawbacks listed below.

Use these insights as guidance before launching your mass messaging strategy.

How to avoid restrictions while sending mass messages on LinkedIn

Despite the perceived downsides of mass messaging, you can utilize it in a safe and ethical way. To maintain a good reputation on LinkedIn and avoid penalties, follow the simple safety rules of mass messaging listed below.

1. Don’t send too many messages at once.

It’s not humanly possible to send multiple messages with a couple of seconds between them. That’s why firing out lots of DMs over a short period of time makes you look like a bot. The algorithm doesn’t like this kind of activity and can penalize you.

Your safe daily message volume depends on your Social Selling Index score. Here are the ranges we recommend sticking by:

If you’re interacting with your audience through automation software, make sure it mimics human behavior. For example, here’s how Snovio keeps you safe:

Snovio not only respects SSI-based LinkedIn messaging limits but also lets you schedule outreach during your typical online hours or when leads are most active. Actions are automatically spaced throughout the day with human-like delays to appear natural.

Also, some actions, such as connection requests, are high-risk but necessary for direct messaging on free accounts or to avoid LinkedIn InMail credits.

Snov.io’s warm-up mode gradually increases your daily request volume to reduce the risk of account restrictions.

2. Personalize each message to appeal to your recipients.

LinkedIn users don’t tolerate generic DMs. Personalization is no longer a “nice-to-have” approach; it’s a must in business etiquette. What’s more, the algorithm distinguishes personalized messages from generic ones. It can flag your account if it detects too many generic messages being sent from it.

Research your leads to understand their goals, pain points, and values. Segment your prospect list based on what these people have in common before setting up your mass outreach campaign. Send DMs that are relevant to each group’s interests and follow their preferred tone of voice.

Also, use variables and dynamic content while utilizing the Snov.io LinkedIn automation tool to achieve the desired level of personalization.

Taking the time to personalize your outreach upfront not only goes a long way in boosting response rates, but also helps keep your account safe from LinkedIn’s algorithm flags.

Here are some ready-to-use LinkedIn outreach templates:

Event invitation

Hi {{firstName}},

I saw that you work in {{industry}} at {{company}} and thought our upcoming webinar on [topic] might interest you. We’re gathering {{jobTitle}} professionals from {{location}} to discuss [specific challenge].

Cheers, [Your name]

Use these LinkedIn outreach templates as a starting point. Making them personal will greatly increase your chances of engagement.

3. Do not send unsolicited sales pitches.

Trying to push your product right away can annoy your recipients and even break their trust. It would be very hard to win back the users who have mentally put you in a “desperate sales rep” category.

Make sure to have a meaningful conversation and learn more about your prospect before trying to sell anything. Otherwise, annoyed recipients may not just refuse to do business with you but also report DMs as spam. Being reported several times can result in restriction or even account suspension.

Steer clear of these red flags that trigger spam detection and annoy recipients:

• Hyperlink density: Keep links to a maximum of 1 per message. Multiple links look automated and spammy.
• All caps: Never use ALL CAPS for emphasis. It gives off desperation and spam.
• Excessive punctuation: Avoid multiple exclamation marks!!! or question marks???
• Overpromising: Avoid claims like “guaranteed results,” “100% success rate,” or “get rich quick.”
• Pushy language: Replace “You need this” with “This might help” and “You should buy” with “Would this be useful?”
• Long paragraphs: Break text into short, scannable sections. Walls of text overwhelm readers.

Sticking to these recommendations demonstrates professionalism and respect.

4. Maintain a good sender reputation by interacting with responses.

The LinkedIn algorithm doesn’t favor users who drop out of the conversation or take a long time to reply. Once you receive responses, don’t forget to write back.

LinkedIn itself hasn’t shared any guidelines on what an appropriate response time is. Still, we suggest interacting with prospects’ replies within 24 hours. This will improve your sender reputation with the algorithm and overall strengthen your relationships.

Save time while maintaining personalization with these adaptable LinkedIn outreach templates:

• Positive interest response: “Thanks for getting back to me, {{firstName}}! I’m glad this resonates with you. Are you available for a short call on [day] at [time] to discuss further?”
• Question response: “That’s a great question, {{firstName}}. [Answer their question]. Does that clear things up, or would you like more details on [specific aspect]?”
• Neutral/exploratory response: “I appreciate you taking the time to respond, {{firstName}}. To make sure I’m suggesting the right next step, could you share a bit more about [their situation/challenge]?”
• Not interested response: “No worries at all, {{firstName}}. I appreciate you letting me know. If anything changes, feel free to reach out. Best of luck with [their initiative]!”
• Timing request response: “Of course, {{firstName}}. I’ll follow up with you in [timeframe]. Meanwhile, here’s [resource] that might be helpful.”

Customize these snippets with specific details from each conversation to maintain authenticity.

5. Keep your messages professional

LinkedIn is a professional networking platform, so treat every interaction with the same courtesy you’d use in a business setting. This applies whether you’re sending individual messages or when you send bulk messages on LinkedIn.

Conversations should remain polite, respectful, and relevant. Violating these standards will result in your account being suspended very quickly. Here’s a handy checklist for maintaining proper business etiquette in all interactions:

• Use proper grammar and spelling

• Avoid slang, excessive emojis, or casual language

• Stay on topic and respect boundaries

• Never send inappropriate, offensive, or discriminatory content

• Respect “no” and stop outreach when someone declines

Being professional yourself is important, but keep in mind that the platform faces ongoing challenges with inauthentic accounts used for espionage, phishing, and scams. It’s crucial that you stay vigilant as well.
