We Emailed 2,000 Crypto Contacts. Here's What the Bounces Told Us About the Industry.
Last week, I ran an outreach campaign across SunDAO’s full contact database for our first online Private Investors Speed Dating. Nearly 2,000 unique emails - people we’d met at events, collected through Luma signups, connected with through partners. Investors, founders, BD leads, developers from across the blockchain ecosystem.
133 emails bounced. Permanently dead. Not “out of office.” Not “mailbox full.” Gone.
6.7% might not sound dramatic. But when we started looking at which emails bounced and why, the picture that emerged was less about email hygiene and more about the state of the crypto industry in 2026.
Dead email addresses are, it turns out, a surprisingly honest map of what’s happening behind the scenes - which companies are quietly laying off, which roles are most volatile, and which segments of the market are contracting.
Here’s what we found.
The older the contact, the faster it dies
The data broke down cleanly by when we collected the contact.
Our EthCC 2026 contacts - about 2 months old - bounced at 2.7%. Abu Dhabi contacts from 6 months ago Solana Breakpoint bounced at 6.9%. And our EthCC Cannes 2025 list, roughly 10 months old, bounced at 11.4%. That’s 1 in 9 contacts gone within a year.
The decay is steeper than anything you’d see in traditional B2B. In SaaS, the standard benchmark is 2-3% annual email decay. We’re seeing 4x that rate in under a year.
The crypto-specific drivers are obvious once you think about them: people change jobs constantly, startups shut down without announcements, protocols rebrand and retire old infrastructure, entire companies get acquihired and the email domain goes dark. The pace of change that makes this industry exciting is the same pace that makes contact lists expire.
Our EthCC Cannes 2025 list still has value - there are real relationships in there. But as a cold-outreach asset? It’s past its useful life. Anything from 2024 is likely 20% or more stale.
BD people disappear 2.5x faster than founders
This one surprised me even though it shouldn’t have.
When we segmented bounces by role, the pattern was stark. Business development contacts bounced at 12%. Founders bounced at 4.8%. CEOs bounced at 1.9%.
BD is the first function cut in any restructuring, and BD professionals in crypto tend to hop between protocols chasing equity upside. ConsenSys, P2P.org, Nansen, MEXC, OKX - every company with multiple bounces in our list showed this concentration. The entire BD team at P2P.org turned over despite the company itself reportedly thriving with $10B+ staked.
For us, this has a practical implication: when we’re building relationships with institutional prospects - validators, DevShops, infrastructure providers - anchoring the relationship to their BD contact is risky. The founder or commercial lead is a much more durable point of contact. BD contacts are a use-it-or-lose-it asset - if you don’t convert the relationship within 6 months, your odds of reaching them drop materially.
Personal email is 25x more durable than corporate
This was the single most striking number in the whole dataset.
Of 686 personal-domain emails (Gmail, Proton, iCloud), 3 bounced - a 0.4% rate. Of 1,309 corporate-domain emails, 130 bounced - 9.9%.
Think about what that means. A personal email captured today has a 99.6% chance of still working a year from now. A corporate email has roughly a 90% chance. In an industry where people move constantly, their personal email follows them. Their company email dies with the job.
We’ve already changed our intake forms based on this. Luma signups for our events now ask for personal email first, corporate as optional. It’s a small change that should cut our future bounce rate by an order of magnitude.
The bounces tell you which companies are in trouble
When we looked at which companies had multiple bounces, patterns appeared that you wouldn’t necessarily see from reading crypto news.
P2P.org had 5 bounces - their entire BD team turned over. But P2P.org itself is fine. It’s a deliberate function rebuild, not distress.
Sonar Platform had 3 bounces including the CEO - because Sonar was acquired by Aave and the original email infrastructure was eventually retired.
Junction Exchange had 3 bounces from what was probably a sub-10-person team. Three out of ten is usually a sign the project is done.
ConsenSys has been through four publicly reported layoff rounds since 2023. Magic Eden shut down its EVM and Bitcoin Ordinals marketplaces in February 2026. Nansen did a 30% workforce cut in 2023 and is still restructuring. OKX reported layoffs in January 2026. Coinbase cut 14% in May 2026.
The bounces confirmed what public reporting suggested - but they also caught quiet departures that never made the news. Seven companies in our bounce list appear to have fully wound down their domains. No announcement. No press coverage. Just... servers stopped responding.
That 7-out-of-133 domain death rate tracks with public reporting that 20+ crypto projects that we knew personally shut down in Q1 2026 alone.
What survived - and what that means for SunDAO
Here’s the part that matters most for our thesis.
Across 133 bounces, the Cosmos and modular blockchain ecosystem was barely represented. The Interchain Foundation, Celestia, Archway, Neutron, AADAO, Posthuman, Skip - none of those organizations had bounces. Zero.
Partly that’s smaller team sizes (less surface area for departures). But it also reflects something structural: these organizations didn’t do the aggressive 2023-2024 hiring binge that led to the 2024-2026 correction at larger companies. They were leaner from the start, which means less correction now.
Meanwhile, the NFT and creator-tooling segment was hit hard. Magic Eden, Metaplex, SNS, Reform DAO, Access Protocol - eight bounces from this cluster alone. Combined with NFT total market cap falling below $1.5B in early 2026 and Nifty Gateway shutting down, this segment is clearly contracting.
The SunDAO database also told a positive story: our existing members had a 0% bounce rate. Every single member’s email still works.
That’s not surprising - these are active, engaged participants who chose to invest and do business together. But it’s a useful contrast against the 6.7% overall rate and the 12% BD rate. The people who are in a community stay reachable. The people who gave you a business card at a conference don’t.
Why being part of a community matters more than ever
This is the conclusion I keep coming back to.
The blockchain industry is volatile by design. Projects launch and die. Teams restructure. People change roles. The entire contact graph reshuffles every year. In that environment, the default way most investors operate - collecting contacts at conferences, sending cold emails, building LinkedIn connections - produces an asset that decays faster than you can use it.
A community is different.
When someone joins SunDAO, they don’t give us a business card and walk away. They join a group of 70+ experts who source deals, evaluate them together, vote on investments, and stay connected through dedicated channels. When a member changes companies, they update us. When they move to a new role, they’re still in the community. When a portfolio company hits a milestone or faces challenges, everyone hears about it in real time.
The bounce data showed us that the crypto industry’s contact infrastructure is fragile. But the relationships inside a community like SunDAO are durable - because they’re built on shared activity, not just a shared conference badge.
If you’re an investor, founder, operator, or service provider in blockchain, think about what your own contact list looks like right now. How many of the people you met at last year’s conferences would actually receive your email today? How many of the BD leads you exchanged cards with are still at the same company?
Now think about what it would be worth to be inside a network where the answer to those questions is “all of them.”
That’s the value proposition we don’t talk about enough. Not just deal flow. Not just collective due diligence. Stability in an unstable industry. A network that doesn’t decay.
