Welcome back to the practical prospecting newsletter.

Today I’m sharing 8 tools and resources I created in collaboration with the Sell Better team that you can use across every step of your outbound strategy.

And yes, they’re actually free :)

Today’s newsletter is brought to you by ZoomInfo.

They recently released GTM Studio, and I’ve been using it for a few months now.

I recorded this in-depth video walking through all the features for anyone who’s curious.

Here are a few things I like most:

  • #1 - Waterfall enrichment is free (to maximize contact data coverage + quality)

  • #2 - The AI agent (to research and personalize emails for bulk lists)

  • #3 - Built-in signal enrichments (signals like ‘podcast mentions’ that you can’t find anywhere else).

The 8 Resources

1. TAM Builder GPT 

Plug in your ICP and it maps out your total addressable market. Including which tools to use for scraping your lists.

It’s useful before you start any new campaign so you're not flying blind on list size.

2. Email Infrastructure Calculator 

Shows you exactly how many inboxes you need based on your send volume targets.

Takes about 2 minutes to use and saves you from burning your domains.

3. Offer Builder 

Helps you craft an outbound offer that doesn't sound like every other cold email in someone's inbox. It’s built on the top offers we’ve actually used in our agency.

Good starting point if your reply rates are flat.

4. Email Campaign GPT 

Builds a full cold email sequence from scratch. Give it your ICP, offer, etc. and it does the rest.

This is built on our internal messaging SOP and the top cold email campaigns we’ve ran. Keep in mind, you’re still going to want to edit before going live with these. But it’ll get you 80% of the way there.

5. Email Template Swipe File 

A library of cold email templates we've actually used and seen success with across client campaigns. Including follow up emails too.

6. LinkedIn Messaging GPT 

The exact process we use to average a 30% reply rate on LinkedIn across all client campaigns.

It’ll help you write LinkedIn DM sequences in a way that actually feels human.

7. Testing & Iteration GPT 

You give it your campaign details, it helps you figure out what to test next.

Again, built on our exact testing and iteration methodologies here at Practical Prospecting.

8. Cold Call Script Generator 

Builds a cold call script around your ICP and offer. Based on the exact scripts that convert for our cold calling team.

Thanks for reading!
