Closely

Closely is a B2B sales engagement platform built around LinkedIn and email outreach, aimed at teams that want to run multichannel campaigns from one dashboard instead of juggling separate tools. The platform automates LinkedIn actions such as profile visits, connection requests, and follow-ups, using smart limits, timing delays, and a warm-up mode intended to keep automated activity looking human and reduce the risk of account restrictions. AI personalization generates one-to-one messages for LinkedIn DMs, InMails, and email based on a prospect's profile and company context, so reps can scale outreach without writing every message by hand. A unified inbox brings LinkedIn and email replies into one place, and built-in analytics track connection acceptance, reply rates, and meetings booked. Closely also enriches leads in real time with verified emails, phone numbers, and company details pulled from more than 30 data sources, and syncs conversations and leads directly into Salesforce, HubSpot, Pipedrive, and GoHighLevel. An agency-focused white-label tier is available for a flat monthly fee. Closely suits sales teams, recruiters, marketers, and agencies running high-volume, personalized outbound campaigns. One limitation worth noting: because it depends on automating LinkedIn activity, its usefulness is bound by LinkedIn's own rate limits and policies, which the platform works around rather than controls.
