Account Protection
Never email your own customers by accident again
Upload one domain list. Every batch you run after that is checked against it before enrichment begins. Customers, competitors, partners, live deals are separated automatically, every time.
Account protection, free on every list
You would never cold-call your own customer. Your team might
Mark the organisations you already work with. Anyone at them is separated from every upload, at no cost, before a single call. Your team decides what stays protected.
| Display name | Match type | Match value | Reason | Status |
|---|---|---|---|---|
| Acme Industries | Domain | acme.com | Customer | |
| Riverside Partners | Domain | riverside.com | Partner | |
| Globex Group | Organisation name | Globex Group | Competitor |
From a sample upload of 8 contacts, Datuma separated 4 before anyone could reach out:
- Mark Rylance Acme Industries Customer
- Sam Patel Acme Industries Customer
- Tom Reed Riverside Partners Partner
- Dana Kapoor Globex Group Competitor
- Jane Okafor Northstar Labs
- Lucy Chen Initech
- Priya Nair Brightline Media
- Dan Whitlock Vertex Systems
4 separated at £0.00, before anyone reached out. Toggle a status above and watch your upload update.

The friendly fire problem
Sales teams buy contact lists. Marketing imports lead-gen exports. New SDRs upload prospecting batches every week. Somewhere in there, a contact at one of your biggest customers gets a cold pitch from your own team.
It's not a hypothetical. Most CRMs have no built-in suppression layer for prospecting workflows. Protected accounts live in someone's head, or in a spreadsheet that's three months out of date. The result:
Customer churn risk
A renewal call goes sideways because procurement got a cold sequence from your SDR last week.
Live deals stalled
Your AE has been working a champion for two months. A second rep cold-pitches their colleague. Trust resets to zero.
Partner conflict
Reselling partners and integration partners get prospected as if they were prospects. The relationship gets a frosty email instead of a referral.
How Datuma handles it
Step 1: Upload your domain list once
Customers, competitors, active deal organisations, partners. One CSV, one upload. Stored persistently on your account, not in someone's head.
Step 2: Every future batch is checked first
Before you pay to enrich anything, every contact in every new batch is matched against your protected list. Matches are separated into their own file with the protection reason attached.
Step 3: Update the list as your business changes
New customer signed? Add the domain. Deal closed-lost? Remove it. Re-upload as often as you want. The latest list applies to the next batch automatically.
Generic team mailboxes are caught too
Generic team mailboxes (support@, help@, info@, sales@) are also caught by Account Protection. They go to the Protected Accounts file because no individual person owns them, which means no AI sequencer or human rep can address them as a named contact. They never appear in your Verified Readiness column.
Every check is £0.00
The protection check runs before enrichment begins, and the check itself is free, every time. Protected contacts are still enriched, scored and billed like any other contact, then delivered in their own file for account handling, not cold outreach.
What you get back
Every batch produces a dedicated Protected Accounts file alongside your enriched contacts. Each row tells you which contact was separated and why: customer match, competitor match, partner match, or live-deal match.
Your team sees the suppression decision before anyone picks up the phone. Your CRM stays clean. Your customers don't get prospected.
And because protection runs at upload time, you find out a contact is already a customer before anyone reaches out.
Protect your accounts before the next batch goes out
Set your protected domain list once. Every future enrichment batch checks against it automatically, at £0.00.
