After extensively testing Instantly, Lemlist, and SalesRobot—running outreach campaigns across both email and LinkedIn—the core differences became apparent:
Instantly is purpose-built for high-volume cold email outreach. With features like inbox rotation, deliverability analytics, and integrated B2B lead data, it's become the preferred choice for cold email agencies managing large-scale campaigns. Its vertically integrated approach combines all needed tools in one clean interface, but this comes with a clear focus on email rather than multi-channel outreach.
Lemlist approaches outreach from a multi-channel perspective, combining email and LinkedIn automation. While it serves small B2B sales teams well for moderate email volumes (under 5,000 monthly), its browser-based LinkedIn automation requires keeping your computer running continuously, limiting its effectiveness for serious LinkedIn campaigns.
However, for B2B teams primarily focused on LinkedIn outreach, both platforms have significant limitations.
This is why I've included SalesRobot in the comparison. Using dedicated residential IPs and mobile APIs, it offers reliable LinkedIn automation with built-in safety mechanisms. This architecture has made it particularly valuable for B2B founders and sales teams who need dependable LinkedIn outreach without risking their accounts.
In this article, I compare these tools across six key areas:
- LinkedIn Automation
- Email Outreach
- Safety & Deliverability
- Multi-channel Capabilities
- AI campaign creation
- AI reply management
I’ll also touch on ease of use and customer support so that you have all the information you need to make the right decision for your needs.
What is Instantly?

What is Lemlist?
"Your multi-channel outreach education + software" 🔄💼

Founded as a solution for multi-channel outreach in 2018 by Guillaume Moubeche and 2 other technical wizards Francois and Vianney, Lemlist aims to bridge the gap between email and LinkedIn outreach for small B2B sales teams.
Their platform combines email automation with LinkedIn outreach capabilities, though users note the LinkedIn features are browser-based and have limitations.
Lemlist shines in its email capabilities, offering features like conditional sequences, custom landing pages, and a large lead database.
While it works well for teams sending moderate email volumes (under 5,000 monthly), the platform's strength lies in its ability to coordinate outreach across multiple channels, making it popular among small B2B sales teams and founders looking for an integrated approach.
What is SalesRobot?
"Making LinkedIn automation safe and reliable" 🛡️🤖
Founded in May 2020, SalesRobot emerged from a clear market need: making LinkedIn automation reliable and safe.
