1. Create a free account — Sign up at Signal Plug in under 30 seconds. No credit card required. The Free plan includes 10 searches per month so you can test the tool with real Insider contacts before upgrading.
2. Enter the contact's name — Type the first and last name of the Insider employee you want to reach. Signal Plug handles all seniority levels, from C-suite to individual contributors.

Why Use Signal Plug for Insider Email Lookup

Most email finder tools pull from static databases of scraped email addresses. These databases go stale as people change jobs and companies update their email infrastructure. Signal Plug takes a different approach: every search performs a live check against insider.com's mail server using SMTP verification. This means results reflect the current state of Insider's email system — not a cached result from months or years ago.

Signal Plug enriches every result with supporting data: a confidence score (0–100), deliverability status (Valid, Risky, or Catch-all), job title where available, and LinkedIn profile URL. This context helps you prioritize which Insider contacts to email first and personalize your outreach before you hit send. Plans start at $29/month for 500 searches — no annual contracts or seat fees.

Frequently Asked Questions — Insider

How accurate are Signal Plug results for Insider?

Signal Plug performs a live SMTP check against insider.com's mail server for every query — not a static database lookup. This means results reflect the actual current state of Insider's email infrastructure at the time of your search. Our platform-wide accuracy rate is 94%. Each result comes with a confidence score (0–100) so you can gauge reliability before using the address.

How many Insider contacts can I search per month?

Does Signal Plug store employee email addresses from Insider?

No. Signal Plug generates and verifies email addresses in real time using SMTP checks — we do not maintain a scraped database of Insider employee emails.

Can I find emails for multiple Insider contacts at once?

Yes. Growth and Scale plan users can upload a CSV or paste a list of names to run bulk lookups against insider.com. Signal Plug processes the full list and returns verified email addresses for all contacts in a single batch, which can then be exported to CSV for import into Salesforce, HubSpot, Outreach, Lemlist, or any other tool.

Does Signal Plug find emails for Insider employees outside Philadelphia?

Yes. Insider is headquartered in Philadelphia, PA, United States, but Signal Plug works for employees at any Insider office or remote location worldwide.
