The short version
Cold email that filled the guest list for Instantly.ai’s GTM show. 2,140 founders got an invite that named their company and a topic they could teach. 272 replied, and 85 were accepted as guests.
The brief
Instantly Show is Instantly.ai’s GTM show, hosted by Eugene Kadzin and streamed on YouTube, LinkedIn and X. Its guests had been booked through LinkedIn and X messages, where founders with big audiences rarely answer.
I built the cold email that filled the guest list: who to invite, where their emails came from, the line in every email written for that one founder, and the sending. A generic podcast invite gets ignored, so each one had to show we knew who the founder was and what they could talk about.
How it runs
- 01Who
Owners of AI and outbound agencies and bootstrapped SaaS with 5K+ LinkedIn followers who post and get engagement, modelled on the show’s past guests.
LinkedIn - 02List
AI Ark found them and Apify pulled their LinkedIn profiles and recent posts. A Clay waterfall across ten email finders, Findymail, Hunter and Prospeo among them, kept only verified addresses, checked again with MillionVerifier. Past guests were taken out.

Three short emails from Eugene in Instantly, across 50 mailboxes on 15 domains: the invite, two real episodes as proof, a one-line close. No tracking pixels.
Instantly - 05Book
Every yes went straight to Eugene’s inbox, where his team picked the guests and booked the recordings.
The result
In the first seven sending days, 126 founders said yes to coming on the show: 7.2% of everyone emailed, and 70% of the human replies. By 11 October the campaign had reached 2,140 founders and drawn 272 replies (12.7%), and Eugene’s team had accepted 85 as guests.
The first email, the one with the line written for each founder, did most of it: a 10.5% reply rate, 34.7% of replies positive, and 78 of the 85 guests. For scale, the same Instantly workspace had run 25 earlier campaigns with a different offer: 39,758 emails and 66 opportunities. This one passed 54 in its first 2,651.
