Cold email nerd. Helping founders and dealmakers start better conversations.

[Kasper Zacho @KasperZacho_]

Most cold email fails for the same 3 reasons:

Wrong list
Emails that are too long
Burned domains

We've spent 5+ years fixing that for B2B companies. My team and I build the lists, write the emails, handle every reply and book the meetings.

I'm new here, and I'll be sharing everything we learn along the way.

If you're doing outreach yourself, follow along. If you'd rather have it done for you, my DMs are open.

@AlexHartsuff a case study only lands when it's from a company that looks exactly like theirs. a random logo is just you talking about yourself

[Kasper Zacho @KasperZacho_]

@samdblond the best email still dies on the wrong list. curious how much of the lift is the writing vs who the agents pick to send it to

[Kasper Zacho @KasperZacho_]

@LukeWarrd 8,364 down to 915 is the part people should pay attention to. when data costs nothing, the edge is knowing which 90% of the list to throw out

[Kasper Zacho @KasperZacho_]

@TechSalesGuy 7 is the one that actually compounds. we run our reply desk the same way, every correction gets saved as a rule so the AI never makes that mistake twice

[Kasper Zacho @KasperZacho_]

Quick test for your personalization.

Delete the first line. If the email still makes sense without it, the personalization wasn't doing anything.

[Kasper Zacho @KasperZacho_]

@MattLucero_ Closing a deal off week one says a lot about the offer. Did you build the list off their best existing customers?

[Kasper Zacho @KasperZacho_]

@NickAbraham12 My guess is retention. When all you sell is meetings, you're easy to cancel the first month a campaign dips. Owning more of the funnel makes you a lot harder to swap out.

@christinaqi The Associates point carries over to cold outreach too. The person one level below the decision maker often reads more carefully and has a reason to bring it upstairs, because finding it makes them look good.

[Kasper Zacho @KasperZacho_]

@systemizedsales And watch the deals that close on an overpromise. The rep gets the commission, the refund lands on someone else, so the comp plan quietly rewards it.

[Kasper Zacho @KasperZacho_]

@alxberman Point 1 is the part nobody says out loud. Every cold email is dead post scares off a few more senders, which leaves more room in the inbox for the people who stuck around.

[Kasper Zacho @KasperZacho_]

@coldemailchris The part I'd put first is judgment on lists. Plenty of people can build the Clay table now, way fewer can look at two lists and tell you which one books meetings before a single email goes out.

[Kasper Zacho @KasperZacho_]

@darynakulya @bot The right-time outreach bot is the one I'd want to see. What's it watching for, usage inside your product or outside stuff like hiring and funding?

[Kasper Zacho @KasperZacho_]

@Tech_Arish The catch is every other sender fed AI the same website, so the angles come out the same. The stuff that isn't on the site gets the replies, like a job post for the exact role your product helps with.

[Kasper Zacho @KasperZacho_]

@itsmarcosruiz Actually answering the question people ask. We're pretty new on X and the reply that got us a follow today was just a straight answer to a question post.

[Kasper Zacho @KasperZacho_]

@itsalexvacca Step 1 is the one that matters. Ask reps where their time goes and they won't mention the copy-pasting, they stopped noticing it months ago. You only see it by sitting next to them.

[Kasper Zacho @KasperZacho_]

Show original is such a quick check. I'd send one to an Outlook inbox too, passing in Gmail doesn't mean Microsoft likes you https://t.co/xKL4ZMVmPn

[Nadia Zueva @nestymee]

3 months of cold emailing creators from a fresh domain. so far 15-25% replies and <1% bounces

how i check a cold email domain is healthy - send one to my own gmail, open “show original” and look for 3 lines

[Kasper Zacho @KasperZacho_]

@StackDhruv Handwritten notes to people who replied to a cold email and then went quiet would be a crazy combo. You already know they care, the note just brings them back.

[Kasper Zacho @KasperZacho_]

@GTM_Papi Makes sense. Do you take the angle from the calls straight into the first email, or test a few versions first?

[Kasper Zacho @KasperZacho_]

Don't judge a campaign on 300 sends.

We don't call a campaign good or bad until it's past 1,000. Before that a couple of lucky or unlucky replies swing everything.

[Kasper Zacho @KasperZacho_]

@JesseTinsley The scary part is the damage doesn't show up right away. The pipeline that team already built keeps closing for a quarter or two, so cutting them looks smart until it suddenly doesn't.

[Kasper Zacho @KasperZacho_]

@lizrhoffman Fair. Most of those AI pitches could've gone to anyone, and that's exactly why they get ignored.
