Verified B2B lead lists for outbound & cold-email agencies. Owner-first contacts, valid-only emails, 30%+ under your Clay/Apollo spend. Founder, OrbitBoyzz
I build B2B lead lists for outbound and cold-email agencies.
Owner and decision-maker contacts first. Emails verified before delivery. At least 30% under what you spend on Clay or Apollo.
Pick one client profile and I'll build 25 leads for it, free:

I often get asked who to follow to learn GTM Engineering.
My answer: Follow people who SHOW the work, not just talk about it.
Here are 12 accounts I'd recommend:
@ENowoslawski : GTM insights, practical tactics, and industry updates.
@MitchellKeller_ : Technical GTM breakdowns and cold email infrastructure.
@Kellen_the_man : Signal-based outbound, targeting, and messaging insights.
@coldemailchris : Real campaign breakdowns and practical GTM Engineering resources.
@shawntenam : Building GTM as code in public and sharing useful resources.
@gtm_engineer : Clay workflows, MCP, and modern GTM systems.
@itsalexvacca : Practical GTM playbooks and creative ways to generate pipeline.
@MichLieben : AI agents, automation, and autonomous GTM workflows.
@retttx : GTM Engineering, Clay, and AI-powered workflows.
@tim_yakubson : Clay workflows and practical GTM knowledge.
@shaw_gtm : Offer positioning, outbound experiments, and messaging that converts.
@bretonwill : Cold email at scale, infrastructure, and deliverability.
Don't just follow them.
Study what they build, test what they share, and learn by doing.

@AshwiniNK21 Nice. One more check worth adding to the pre-flight: flag rows where the email domain doesn't match the company domain. Catches stale job-change contacts before they bounce.
@Kenny76583159 Same order we use: check bounce rate and inbox placement by provider before touching copy. A 0.4% reply rate with 5% bounces is a list problem no rewrite fixes.
You're probably adding GTM motions in the wrong order.
In the 310+ pipelines we've audited, execution order is the probably the biggest issue. So here's how to do it in the correct order (along with the signs that it's working):
Base rule: Get RevOps right first, and add the motions that fit your buyers on top of it.
1. RevOps
For every team and every deal size. It's the system every other motion writes into.
Start with: 1 clean CRM (HubSpot, Salesforce or Attio) and routing in n8n.
Sign it's working: every lead has an owner and a source.
2. Outbound
For buyers you can name and list, with deals big enough to pay for a rep's time.
Start with: signals in @clay and cold email in @InstantlyAI.
Add: work emails from @prospeo_io, and mobiles from @FullEnrich for the top tier.
Sign it's working: replies from the accounts with 3 signals.
3. Content
For a founder with a point of view and more importantly, a sales cycle that runs primarily on trust.
Start with: founder posts and ideas from sales calls (Fireflies).
Sign it's working: comments from people with your target titles.
4. ABM and paid ads
For a named account list and deals big enough to spend on.
Start with: account audiences on LinkedIn and Thought Leader Ads.
Sign it's working: pipeline from target accounts, tracked channel by channel.
5. Partnerships
For buyers other companies already sell to, or happy customers who can refer you.
Start with: warm intros (The Swarm) and referrals (Influitive).
Sign it's working: meetings that arrive with an intro attached.
6. Community
For buyers who learn from their peers, and deals that need trust.
Start with: podcasts with buyers as guests, and small events.
Sign it's working: guests and attendees who take a meeting.
7. AEO
For buyers who research vendors in ChatGPT, Claude or Perplexity.
Start with: AI share of voice (Profound) and answer-first pages.
Sign it's working: your name on the AI shortlist.
Some key rules to keep in mind:
> RevOps owns the list, because they know which segments convert
> at least 3 signals stacked on every outbound deal we've closed
> each ad channel tracked on its own
> the first line written for the buyer you want
> a spot on the 3-vendor shortlist an AI agent builds
All 52 plays, with the tool and how to run each one, are in the article below:
@_shubham_24 Good use of warmup weeks. We also re-verify the list at the end of warmup, not the start, since a few weeks of decay can push bounces past 2% on day one.
@jn_jackk Worth splitting results by recipient provider before panicking. If Google-hosted prospects hold steady and only Outlook drops, it's on their side, so pause Outlook sends for a day instead of burning domains.
@aporiabuilds Most bounces come from guessed or dead addresses, not Gmail itself. Verify every address before upload, drop the invalids, and send catch-alls in a small separate batch. Gmail-run SMBs are fine if they verify clean.
The order I fix it in:
- Verify every row the week you send
- Split catch-alls into their own low-volume send
- Drop any source that keeps failing
Then judge the copy.
Most "cold email doesn't work" posts are really bounce problems wearing a copy costume.
Before you rewrite the sequence, check how much of the list actually reached a real mailbox.
@the_rza_ AE verdict is the right loop. I'd feed back wrong-person meetings too, since those usually trace to stale contact data rather than the agent's targeting.
@pravitbhatia_ Agree. Real results posts would also show the boring stuff, like bounce rate per list source. That number says more about a campaign than inbox count does.
@rohitmal Trigger first is the right order. Worth adding a freshness check too: a funding or hire signal from 90 days ago often means the contact data has gone stale.
@JoshBolstad2 Day-one sends kill a lot of domains. The other quiet killer is the first list: even fully warmed inboxes struggle if batch one bounces at 6 to 8%.
@Alexzartarian ICP first is right. I'd add a third: knowing why now. A list of perfect-fit companies with no trigger still reads as random to the person opening the email.
@floris_vec Same setup, different outcome is wild. Did the twins ever pull from a different list batch? Sometimes one mailbox just draws more dead addresses or traps.
@lukepierceops Deliverability sections usually focus on domains and warmup. The piece people skip is the list feeding it: one batch with high bounces can undo weeks of warmup.
