Automate your LinkedIn and email prospecting in smart multichannel sequences — cloud-based, safe, and built to book more meetings.
Leadin is a French-built, cloud-based B2B prospecting platform that launched in 2020 with a single focus: help sales teams book more qualified appointments without juggling five separate tools. It combines Automation">LinkedIn automation, cold email campaigns, an integrated email finder and verifier, unlimited mailbox warmup via its InboxFlare partnership, and hyper-personalized visuals — all in one drag-and-drop sequence builder.
Over 500 international partner companies use it, and the platform has earned a 4.8/5 rating from 450+ customer service reviews, with an average live support response time of under 30 seconds.
Leadin's smart multichannel sequences let you chain LinkedIn connection requests, InMails, profile visits, and cold emails using if/else conditional logic — so the sequence automatically routes each lead down the most effective path based on their behavior.
The integrated email finder discovers and verifies professional emails directly from LinkedIn profiles, achieving a success rate between 25% and 40% depending on the industry, with no third-party enrichment tool needed.
A built-in Merged Inbox consolidates every reply — whether from LinkedIn or email — into one workspace with lead labels, saved response templates, and real-time status tracking. Unlimited email accounts can be connected at no extra cost and rotated automatically across campaigns to protect deliverability.
The platform also supports hyper-personalized images and GIFs that dynamically inject a prospect's profile photo, first name, company name, and custom variables — a feature Leadin reports drives up to a 63% lift in reply rates. Leadin operates entirely from the cloud, meaning campaigns run around the clock even when your laptop is closed, with no browser extension required.
Salespeople and SDRs running outbound LinkedIn campaigns at scale benefit most from Leadin's adaptive sequencing and daily limit controls, which allow up to 100 connection requests and 120 messages per day.
Recruitment teams use it to automate outreach to passive candidates and follow up via email when LinkedIn goes unanswered. Marketing agencies and freelancers manage multiple client accounts through separate user subscriptions, each with full feature access at the flat €97/mo per-user rate.
Companies that want zero in-house execution can also outsource their entire prospecting operation to Leadin's in-house agency, which has run 1,500+ campaigns and generated over 10,000 qualified appointments for 350+ clients.
At €97/mo per user, Leadin is priced in the mid-range for LinkedIn automation tools. The flat model — which includes unlimited email accounts, unlimited warmup, unlimited sequences, and an integrated email finder at no extra charge — delivers genuine value versus assembling equivalent tools separately, which could easily cost €150–€250/mo.
The 14-day free trial requires no credit card and gives full platform access. For B2B teams that want a single, well-supported, multilingual tool to run LinkedIn and email outreach together without per-seat add-ons eating into their budget, Leadin is a well-rounded, field-tested option.
Leadin is a French cloud-based B2B multichannel prospecting software founded in 2020. It automates LinkedIn outreach and cold email campaigns through smart if/else sequences, combining an integrated email finder, unlimited mailbox warmup, and dynamic visual personalization in one platform. It also offers a done-for-you prospecting agency service for teams that prefer to fully outsource their lead generation.

• Hyper-Personalized Images & GIFs — Automatically inject a prospect's profile photo, first name, company name, and custom variables into campaign visuals; Leadin reports up to 63% higher reply rates from this feature.
• Merged Smart Inbox — All LinkedIn and email replies arrive in one unified workspace with lead labels (e.g., “Interested”, “Follow Up”), saved reply templates, and multi-campaign overview.
• Cloud-Based Automation">LinkedIn Automation — Connect your LinkedIn account via a dedicated proxy for safe, human-like automation that runs 24/7 without needing your browser open or your computer on.
• A/B Testing — Test message variants, subject lines, and sequence steps to identify what drives the best reply and conversion rates across campaigns.
• Agency Services — Fully outsource your B2B prospecting to Leadin's in-house team, which has managed 1,500+ campaigns and delivered 10,000+ qualified appointments for 350+ companies.
Leadin is built for B2B professionals who need to book more qualified meetings without manually managing LinkedIn and email outreach across separate tools.
• SDRs and outbound sales reps — Benefit from adaptive multichannel sequences that automatically shift from LinkedIn to email when connection requests go unanswered, maximizing touchpoints per prospect.
• Recruitment teams — Use Leadin to find, engage, and follow up with passive candidates at scale via Automation">LinkedIn automation and integrated email outreach in a single coordinated workflow.
• Marketing and growth agencies — Manage multiple client prospecting campaigns under individual user subscriptions, with full feature access and a centralized inbox per account.
• B2B founders and consultants — The 14-day free trial with no credit card required lets early-stage founders validate outreach channels before committing, and the €97/mo flat rate keeps costs predictable as they scale.
• Companies wanting done-for-you outbound — Teams with no in-house SDR capacity can hand off prospecting entirely to Leadin's agency, which has a proven track record of 10,000+ qualified appointments delivered.
Leadin differentiates itself from most Automation">LinkedIn automation tools through a combination of included enrichment, unlimited warmup, and a dual software-plus-agency model.
• Integrated email finder with no credit cap — Most tools charge per email searched or limit monthly lookups. Leadin includes the finder and verifier in the base subscription with no additional cost, eliminating a recurring €30–€80/mo line item that most competitors add.
• Unlimited InboxFlare warmup on all plans — Email warmup is either sold separately or limited to a set number of mailboxes on competing platforms. Leadin includes unlimited warmup for every connected account through its InboxFlare integration, protecting deliverability from day one.
• Human-like typo correction in automation — Leadin's system automatically detects and corrects typographical inconsistencies in prospect names (e.g., mixed-case first names pulled from LinkedIn), a small but meaningful detail that makes automated messages feel far more natural and reduces the chance of looking like a bot.
• Cloud-based proxy architecture — Unlike Chrome extension-based tools that require your browser to stay open, Leadin operates entirely from the cloud via a dedicated proxy assigned to your LinkedIn account. This means campaigns continue running overnight or while you're on vacation without any dependency on your hardware.
• Built-in agency fallback — If your team lacks SDR capacity, Leadin offers a fully managed prospecting service staffed by the same team that built the software. Having access to both the tool and human execution under one roof is uncommon at this price tier.
Leadin connects with the core tools in a modern B2B sales stack through native integrations and API access.
• LinkedIn (Free, Premium, Sales Navigator, Recruiter Lite) — Fully compatible with all LinkedIn account tiers; Sales Navigator targeting unlocks advanced saved-search imports and extends daily action capacity beyond standard limits.
• Gmail and Outlook — Connect unlimited Gmail and Outlook mailboxes directly to Leadin campaigns with automatic sender rotation; standard SMTP accounts are also supported for custom email providers.
• CRM Platforms (via API) — Native API access on the base plan allows two-way data sync with CRMs such as HubSpot and Pipedrive; teams using Salesforce or custom CRMs can connect via API endpoints or Zapier workflows.
• Zapier — Trigger Leadin actions or push lead data to hundreds of third-party tools via Zapier, including Slack notifications, Google Sheets logging, and CRM record creation.
• CSV Import / Export — Import prospect lists from any source in CSV format and export campaign results and lead data for use in external reporting tools or spreadsheets.
