Overview — What Each Tool Does
Handshake
Handshake is a cloud-based LinkedIn automation platform designed from the ground up for multi-sender rotation. It lets teams manage unlimited LinkedIn sender accounts from a single dashboard with built-in warmup scheduling, a unified inbox, and premium residential proxies included on every plan. Pricing is based on sender accounts — not per-seat — so your entire team collaborates without multiplying costs. Plans start at $69/month for 1 sender and scale to enterprise volumes.
Closely
Closely is a multichannel outreach platform that combines LinkedIn automation with email campaigns and AI-powered personalization. The platform offers automated LinkedIn connection requests, messaging sequences, profile visits, and InMail capabilities alongside cold email outreach. Closely's standout features include AI personalization that crafts unique messages based on prospect profiles, a built-in smart inbox for managing conversations, CRM integrations with HubSpot and Salesforce, and lead enrichment tools that find verified email addresses. The platform also offers LinkedIn account warm-up functionality and white-label options for agencies. Pricing follows a per-user model: the Starter plan costs approximately $49 per user per month, the Growth plan is around $99 per user per month with advanced features, the Essential plan runs about $205 per month for up to 5 LinkedIn accounts, and the Custom plan is approximately $350 per month for 10 accounts. For teams managing multiple senders, costs can add up quickly compared to platforms with sender-based pricing. Closely targets sales teams and agencies that want LinkedIn and email in a single workflow without switching between tools.

Where Handshake Wins
Handshake's core advantage over Closely is its purpose-built multi-sender rotation engine. If your outreach strategy involves distributing connection requests and messages across multiple LinkedIn profiles to maximize volume while staying under LinkedIn's radar, Handshake handles this natively. Closely treats each LinkedIn account as a separate entity — there's no automated rotation logic to spread outreach load across senders, which means you're managing each account's campaigns individually.
The pricing difference becomes significant at scale. Handshake's 5-sender plan at $199/month includes unlimited team seats, meaning your entire sales team, account managers, and leadership can access the dashboard without additional cost. With Closely's per-user pricing on the Growth plan, adding 5 users at $99 each costs $495/month — and that's before you factor in the cost of additional team members who need dashboard access. At 10 senders, Handshake costs $299/month versus Closely's Custom plan at $350/month or significantly more on per-user tiers.
The unified inbox across all sender accounts is another area where Handshake excels. Instead of checking replies in each LinkedIn account separately or switching between account views, Handshake aggregates every conversation from every connected sender into a single stream. This is critical for teams where one person manages replies across multiple sender profiles. Handshake's included premium residential proxies also provide a safety advantage — each sender gets a dedicated residential IP that makes automation look like normal human browsing, reducing the risk of LinkedIn restrictions.
Where Closely Wins
Closely wins decisively on multichannel capabilities. If your outreach strategy requires LinkedIn and email working together in unified sequences — for example, sending a connection request, following up via email if not accepted, then retrying on LinkedIn — Closely handles this natively. Handshake focuses exclusively on LinkedIn, so you'd need a separate cold email tool to replicate this workflow.
Closely's AI personalization is genuinely impressive. Instead of relying on basic template variables like first name and company, Closely's AI analyzes each prospect's LinkedIn profile and generates unique message copy tailored to their experience, interests, and recent activity. This level of personalization at scale is something Handshake doesn't offer natively.
The built-in lead enrichment feature is another strong point — you can find verified email addresses and enrich prospect data without leaving the platform or paying for a separate data tool. Closely's native CRM integrations with HubSpot and Salesforce also save time for teams that rely on CRM workflows. The white-label option is valuable for agencies that want to present a branded experience to their clients.

Frequently Asked Questions
Is Handshake cheaper than Closely for teams?
Yes, especially for larger teams. Handshake includes unlimited team seats on every plan, while Closely charges per user on most tiers. At 5 senders, Handshake costs $199/mo vs. up to $495/mo on Closely's per-user plans. The savings grow as you add more team members who need dashboard access.
Does Closely support multi-sender rotation?
No. Closely manages multiple LinkedIn accounts but treats each one independently. There's no built-in rotation logic to automatically distribute outreach across senders — you'd manage each account's campaigns separately.
Can Closely replace both a LinkedIn tool and an email tool?
Yes, that's one of Closely's strengths. It combines LinkedIn automation and cold email outreach in unified multichannel sequences, so you don't need separate tools for each channel. Handshake focuses exclusively on LinkedIn.
Which tool is safer for LinkedIn accounts?
Both are cloud-based, which is safer than browser extensions. Handshake includes premium residential proxies on every plan and has built-in human-like sending patterns. Closely offers cloud-based execution with safety limits. Handshake's explicit proxy infrastructure gives it a slight edge on account safety.
Can I use Handshake and Closely together?
Technically yes — you could use Handshake for LinkedIn multi-sender outreach and Closely for email campaigns. However, most teams choose one primary outreach platform and pair Handshake with a dedicated cold email tool if needed.
