Digital Marketing Intern

Co-Founder & CEO at LeadHaste - a world-class B2B lead-gen agency that sends you ready-to-buy prospects so your team can spend time on what matters most: closing deals.

Most outbound campaigns look the same.

This one didn’t  and it crushed.

We tried an approach that felt wrong at first.

Across 6 - 7 sequences per campaign, reply rates jumped from 1.89% to 30%+.

Positive replies held steady above 70% and worked at scale.

Comment “PLAYBOOK" and I’ll DM everyone (We need to be connected) with the exact playbook, message flow, subject lines, and reasoning behind each step. 

It’s a bit unorthodox, but it works.

Stop tweaking copy. Fix your prompts instead.

We just got this OpenAI block for “10B tokens.”

We’re not a big deal. We just use this stuff every day.

Here are 9 prompting tips you can apply right now as a GTMe that actually work.

1. Talk, don’t type.
Voice to text lets you think out loud, add nuance, and hand the model way more context in less time.

2. Show examples, not vibes.
Give 3-4 pairs of “Input → Output” so it can copy the pattern you want.

3. Load it with context.
Tell it who you are, who it’s for, the goal, the tone, and the constraints before you ask for anything.

4. One job at a time.
Split the work into steps like subject line, opener, CTA, then run them in order.

5. Lock the format.
Ask for a fixed layout or JSON so the output is predictable and easy to reuse.

6. Bring your own facts.
Do quick human research, pass the key numbers and links in, and have AI do the writing and framing.

7. Add guardrails.
Use slots like {company} and {benefit}, word caps, banned phrases, and style rules so it stays on brief.

8. Ask it to think.
Say “show your steps” or “explain the reasoning” so you can spot weak logic fast.

9. Iterate at least three times.
Your first prompt is a sketch, so tighten instructions, tweak examples, and rerun until it snaps into place.

❓What else would you add to that list?

OpenAI token of appreciation to LeadHaste for passing 10 Billion Tokens.

Stop burning good domains. Auto-pull weak inboxes before they tank your campaigns.

Here is an n8n workflow to automatically remove underperforming inboxes from Smartlead campaigns.

We kept losing time removing inboxes by hand.

So I wired a simple n8n flow that removes risky inboxes from campaigns every morning.

Here’s the simple version.

Step 1. Schedule the workflow for early morning.

Step 2. Set Smartlead API key and the client ID you want to maintain.

Step 3. Fetch all campaigns for that client and filter to Active.

Step 4. Pull the email accounts attached to each campaign.

Step 5. De-duplicate to unique inboxes.

Step 6. Check Smartlead warmup reputation and flag inboxes under your threshold. We use 98% as the line.

Step 7. Map inbox → campaigns to avoid API errors.

Step 8. Call Smartlead API to remove those inboxes from the mapped campaigns.

Result.

- Fewer bounces and blocks.
- Higher reply rates.
- No manual triage.
- No wasted leads.

You can duplicate the “client” block to maintain multiple Smartlead accounts. Just swap API key and client ID in the yellow fields.

If you want the import-ready JSON, like this post, comment “BAD EMAILS” and send a connection request.

I’ll DM it to you once we’re connected.

I can only send it if we’re connected.

There are 20k–50k GTM/lead gen agencies in the world.

About 8k of the very best use Clay (based on Clay’s May 2025 funding announcement).

That number is likely closer to 10k by now.

From those 10k, just 132 are selected as official Clay Solutions Partners.

That’s about 1.3% acceptance rate among the best, not the entire 20k–50k.

We’re proud to say we’re now one of them.

It’s easy to forget the impact behind the day-to-day grind.

Work can feel daunting and messy at times.

But moments like this remind us that what we build matters and it’s recognized.

Small wins add up. This one’s worth celebrating.

What's your small win for today?
