Heyo!

Last week, we had a webinar with the ZeroBounce team, where we showed how we build our own outbound (check it out here).

A lot of people were impressed by not only strategy but also the mall growth hacks I showed (like Sales Navigator Formula) 🔥

So I’ve decided to share my fav cold email & lead gen Free growth hacks ❤️

Find Anyone’s LinkedIn Profile Growth Hack

There are 2 things that you need to know about your contacts for outbound:

  1. Email
  2. LinkedIn profile

With email it’s easy, you can use any Chrome extensions or tools to find emails.

With LinkedIn, it’s a bit harder…

So we’ve made a Google Sheet’s Growth Hack that finds anyone’s LinkedIn Profile for FREE, check it out how it works:

Google Sheet with company, title, name and email columns where a formula fills in each contact's LinkedIn profile

Here is a quick video on how to implement it:

Cold Email Planning Calculator

Most founders and sales teams say:

“We need 20 qualified leads/month.”

Then they send 500 emails and hope for magic 🪄

❌ The math doesn’t work.

Not in 2025. Not with how reply rates are tanking across the board.

✅ The Fix: This Cold Email Calculator

We built a dead-simple, interactive Google Sheet.

You just plug in:

  • 🎯 Your monthly lead goal
  • 📬 Your average reply rate (or use our benchmarks)
  • 👍 Your positive reply rate
Cold email calculator sheet: 20 leads a month at a 3% reply rate needs 3,333 contacts, 14,000 emails, 42 mailboxes and 14 domains

Grab the Calculator → here.

100% Email Verification Growth Hack:

Do you know that Google might tell you what email exists and what doesn't?

Yes - Google tells it directly!

Here is how to do it:

  1. Select all emails in your Google Sheets
  2. Convert it to "People" using Smart Chimps
  3. Everyone who was converted = 100% valid email

*it works only for emails on Google

Sales Navigator Growth Hack

Sales Navigator is amazing, but combining both “Account” & “Lead search” is challenging, so we’ve developed our way to scrape the most relevant people.

  1. We find relevant companies;
  2. We scrape them;
  3. We use the formula (download below) with titles we want to scrape

As a result, it creates a unique Sales Navigator URL, that we can scrape in bulk using Phantombuster or TexAu.
