Why it works?
Until now, there was no reliable way to automate Comment-to-DM on LinkedIn.
It’s just not possible to reply to every comment manually.
Is using Second Brain Labs’ LinkedIn automation safe and compliant?
Absolutely. Our LinkedIn Sales Automation engine mirrors natural human behaviour, throttles actions inside LinkedIn’s daily limits, and routes every request through local-IP clouds so your profile stays under the radar.
How realtime is the Comment To DM?
Second Brain Labs’s LinkedIn comment-to-DM feature refreshes posts in timelines within 20 minutes to an hour, depending on the chosen subscription plan.
How many connection requests or messages can I send per day?
You can send up to 200 connection requests per week and up to 200 messages daily. The system auto-adjusts based on your account’s age and activity, ensuring your LinkedIn outbound automation always stays within LinkedIn’s guidelines.
Do I need Sales Navigator or a Premium plan?
Yes, Second Brain Labs (SBL) recommends using a Premium or Sales Navigator account to enhance account security for your LinkedIn AI SDR workflows and reduce the risk of restrictions.
Is there a free trial and how is pricing structured?
Enjoy a 7-day, all-features trial. After that it’s one flat monthly plan—optimized for unlimited LinkedIn Sales Automation—with volume discounts. Cancel anytime.
Can I manage multiple LinkedIn accounts or run client campaigns?
Yes. Agencies can create unlimited workspaces, each with isolated inboxes, safety limits, and separate reporting—perfect for multi-brand B2B LinkedIn outreach. Switch between brands in two clicks.
