Features

See it in Action


MassProspecting monitors LinkedIn’s public feed in real time, identifying leads who just posted something relevant — what we call a “talk signal.”

It then enriches each post with verified contact details (email, phone, company data) and generates a personalized message tailored to that post.

This means you’re not just reaching out — you’re showing up with context, right when your lead is most active and receptive.

Step 1: Search & Target

Use LinkedIn’s public feed to find posts matching your criteria. Filter by Industry and Job Position, then click “Search Preview” to verify that you’re hitting the right audience.

Step 2: Data Enrichment

We append missing details—like country, email and headcount—using our enrichment engines. Enforced filters (e.g. “only valid emails”) ensure each lead meets your quality bar.

Frequently Asked Questions (FAQ)

No. MassProspecting provides built-in LinkedIn accounts for scraping, so you don’t need to connect or risk your personal account.

This keeps your LinkedIn profile safe while still getting fresh, real-time data from the platform.

1 credit is consumed for each lead discovered that matches your order filters and includes a verified email address.

If you requested phone numbers, an additional 2 credits are used per lead that includes a direct phone number — bringing the total to 3 credits per lead with phone.

We typically scrape up to 25 new LinkedIn posts per hour.

The number of leads you receive each day depends on:

  1. How many new posts appear in your LinkedIn search results every hour.
  2. How many of those posts are authored by people who match your filters and have a verified email (and direct phone number, if required).

During the $1 trial, you receive up to 20 credits.

The number of leads that you will receive depends if you have requested valid email addresses only (1 credit per lead) or valid email addresses and direct phone numbers (3 credits per lead).

It depends on your order settings:

  • If you selected “only leads with phone numbers,” then all your leads will include a phone number and cost 3 credits each.
  • If you did not request phone numbers, then none of your leads will include one, and each lead will cost just 1 credit.

Not necessarily. When available, we prioritize direct mobile numbers. However, some numbers may be landlines, company desk phones, or VoIP numbers.

Yes. We run real-time email verification before delivering a lead. Only emails marked as “valid” are included in your list — minimizing bounce rates.

A talk signal is a clue that someone recently posted something relevant on LinkedIn, and may be open to a conversation.

For example, someone posting about hiring, launching a new service, raising funds, or celebrating a promotion. These “talk signals” help you engage leads at the right moment — when they’re most active and approachable.

Yes — but only for 3 months. If credits go unused for more than 3 consecutive months, they will expire.

Make sure to keep your scraping orders running so you make full use of your credits.
