Is the company still trading? A five-minute check before you emailNovember 01, 2026Companies that stopped trading stay in old lists
Every contact list carries dead companies, and every email you send to them burns your sender reputation. Before you hit send, spend five minutes checking if the company is still trading — it's the easiest way to protect your pipeline and your domain.
Why Dead Companies Linger In Your Lists
Contact lists decay silently. Companies dissolve, get acquired, rebrand, or simply stop paying for their domain — but your CRM doesn't update itself. A prospect who was viable six months ago may now be a shell with a parked website and a dead inbox. Because no one flags it, the contact stays in the sequence, and your team keeps emailing into the void.
The problem compounds with purchased or scraped lists, where verification happened once and never again. Even opt-in lists suffer: people change jobs, companies pivot, and entire industries contract. Without a periodic re-check, you're prospecting into a graveyard — and mailbox providers notice. High bounce rates and spam complaints from dead addresses drag down deliverability for every legitimate lead generation effort you run.
- Company closures and acquisitions rarely trigger CRM updates
- Purchased lists are verified once and never refreshed
- Job changes and pivots orphan contacts without warning
- Dead addresses cause bounces that damage sender reputation
Check One The Company Website
Start with the obvious: open the company's homepage. A live, maintained site usually means the business is operating. Look for recent blog posts, updated copyright years, active product pages, and working contact details. If the site redirects to a different company, that's a strong signal of acquisition — the original entity may no longer be a viable prospect.
Watch for the telltale signs of abandonment: broken layout, placeholder text, 'lorem ipsum', or a single page with no navigation. A site that loads but hasn't been touched in years is a soft warning. Cross-check the About page and team section — if leadership names are missing or outdated, the company may be dormant. Five minutes here eliminates the most obvious waste.
- Check copyright year and last blog post date
- Note redirects to another domain or parent company
- Look for broken pages or placeholder content
- Verify team and contact pages are current
Five checks before contacting a company
Check Two The Company Registry
Official registries are the ground truth. In the UK, Companies House shows filing status, accounts, and dissolution notices. In the US, state Secretary of State databases list active, revoked, or dissolved entities. The EU has equivalent national registers. Search the exact legal name and check the status field — 'active' or 'dissolved' is unambiguous.
Pay attention to filing history. A company that hasn't filed accounts in two years is likely dormant or in trouble, even if not formally dissolved. Also check for insolvency notices or administration filings. Registry checks take two minutes and give you a defensible answer about whether the entity legally exists — something no email verification tool can tell you.
- Search the legal name in the relevant national registry
- Confirm status is active, not dissolved or revoked
- Review recent filing history for gaps
- Look for insolvency or administration notices
A parked domain is a dead contact
Check Three Social Presence
A company's social accounts are an activity heartbeat. Check LinkedIn first: is the company page active, are employees posting, and does the headcount look stable? A page with no posts in a year, or one that redirects to a parent brand, suggests the entity has changed. Cross-check Twitter/X and Facebook for recent updates and responses to customer queries.
Social checks also reveal pivots. If the company now describes itself differently — new product, new market, new name — your pitch may be irrelevant. And if key contacts have updated their profiles to a different employer, your prospect has moved on. That's not a dead company, but it's a dead contact, and either way the email you were about to send is wasted.
- Check LinkedIn company page for recent posts
- Confirm employee profiles still list the company
- Look for rebrands or pivots in recent messaging
- See if customer questions are being answered
Check Four DNS Records
DNS is a fast technical signal. Run a lookup on the company's domain for A, MX, and TXT records. A missing A record means the domain doesn't resolve — the site is gone. Missing MX records mean the domain cannot receive email at all, so any address you have is guaranteed to bounce. TXT records can reveal verification services, SPF setup, and whether the domain is actively managed.
You can run these checks from the command line in seconds (dig or nslookup) or through free web tools. The key insight: a domain without MX records is not a viable email target, no matter what your list says. This single check removes a large share of guaranteed bounces before you ever compose a message.
- Check A record resolves to a live server
- Confirm MX records exist for email delivery
- Review TXT records for active management
- Use dig, nslookup, or free online DNS tools
Check Five MX And What A Parked Domain Looks Like
A parked domain is a placeholder — often a single page of ads, a 'domain for sale' notice, or a generic holding page from a registrar. It may still resolve and even show content, which fools a quick glance. But parked domains typically have no MX records, no real contact form, and no company information. They exist to capture residual traffic, not to do business.
MX checks overlap with DNS but deserve their own pass because email is the point. If MX records point to a parking service or are absent entirely, the company is not trading in any meaningful sense. Combine this with the registry check: a dissolved company with a parked domain and no MX is triple-confirmed dead. Remove it from your prospecting list and move on.
- Parked pages often show ads or 'domain for sale'
- No MX records means email cannot be delivered
- Parked domains lack real contact or company info
- Combine registry and MX checks for certainty
Automating The Five-Minute Check
Manual checks work for a handful of contacts, but not for a list of thousands. Automate the mechanical parts: DNS and MX lookups via API, registry status via data providers, and website liveness via HTTP status checks. Many CRM and sales engagement tools support enrichment workflows that flag bounced domains or inactive companies before a sequence starts.
Build a simple pre-send gate: any contact whose domain fails DNS or MX checks gets suppressed automatically. Schedule quarterly re-verification for your whole list, since companies die quietly. The goal isn't perfect data — it's removing most of the waste with minimal effort. Five checks, mostly automated, keep your lead generation clean and your sender reputation intact.
- Use DNS and MX APIs to flag dead domains automatically
- Integrate registry status data into CRM enrichment
- Suppress contacts that fail technical checks before sending
- Re-verify your full list quarterly to catch decay
Dead companies in your list aren't just wasted sends — they're a slow leak in your sender reputation. Run the five checks, automate what you can, and keep your prospecting pointed at companies that actually exist.

FAQ
How often should I re-check my contact list for dead companies?
Quarterly is a practical baseline for most B2B lists. High-churn industries may need monthly checks. Automate DNS and MX checks so re-verification is continuous rather than a big manual project.
Can a company be trading without a website?
Yes, some small businesses operate without a site, but they usually still have MX records and a registry entry. If the domain has no MX records and the registry shows dissolution, treat the company as inactive regardless of other signals.
What is the fastest single check I can run?
An MX lookup. If the domain has no MX records, email cannot be delivered, so the contact is guaranteed to bounce. It takes seconds and removes a large share of waste before you compose anything.
Does a parked domain always mean the company is dead?
Not always — a company may have moved to a new domain after a rebrand. But a parked domain with no MX records and a dissolved registry status is a strong signal the original entity is no longer trading.
