What stale contacts cost

One sample list of 5,000 was mailing 312 dead addresses twice a month. That is postage, tooling and sender reputation spent on nobody, roughly £300 a quarter in this illustrative example.

Movers

Possible moves, flagged early

When a contact shows signs of a possible role or company change, we flag it and show the evidence. You confirm each one. We never guess for you.

Control

Additive only

Results arrive in new fields with a verdict, a date and the evidence behind it. Nothing in your CRM is overwritten, ever.

Real screens, from a real batch

Everything below is the live portal on our own account, shown as it looks. One completed 99-contact batch. Sample figures, not a promise of your results.

Portal report action plan panel. 62 of 99 ready to contact now, with counts for email outreach, confirm the email, and do not email as-is, plus 2 role or organisation changes flagged to confirm
The action plan. Every contact lands in one of four buckets, so your team knows who is ready to contact now, who needs a confirm first, and who to leave.
Email findings panel. 99 contacts in this batch, 72 with a current work email on file, 81 confirmed deliverable by a live check
The email funnel. Contacts in, current work emails found, and the ones that cleared a live mailbox check.
Data integrity panel listing what was held back on this batch. 4 records kept as uploaded, 2 role or organisation changes queued for review, 20 stale job moves held back, 6 possible wrong person matches held back
What we did not change. Uncertain matches are held back and queued for your review, never silently written over your records.
Batch cost panel. Datuma processing £2.97, enrichment £14.50, verification £4.10, total £21.57, and £2.16 of this goes to Camp Mohawk
The bill, in pounds, line by line on every report. 10% of it goes to Camp Mohawk.

How that report gets made

How we get there, in six steps

01Upload your file

A spreadsheet export from your CRM is all it takes. CRM connect is in early access.

02Structural scan, free

Row counts, duplicates, missing fields. No lookups and no card.

03Live checks

Contacts tested against live sources the moment you run them, never a stored snapshot.

04Verdicts with reasons

What passed, what did not, and when, with the evidence behind every verdict.

05Written back, additive only

Results land in new Datuma fields beside your data, one way out. Nothing overwritten. Early access.

06Kept current

Re-tested over time as things change, so the work does not quietly rot.

What is Datuma?

Datuma is the independent tester of B2B contact data, the checkpoint before your AI or outreach acts.

Upload your contacts and we run deduplication, flag the dead records, catch who has moved with role or company change detection, and check every live contact for a Trust Score and Verified Readiness tier.

You get back a clean, ranked list of who is real, who has moved on, and who is ready to contact. One way out, additive only. Nothing moves without you.

Datuma · Independent contact data checks for revenue teams
Sample preview, nothing is saved to your account

Upload contacts

Drop a spreadsheet export from your CRM. We'll propose column mappings, flag quality issues, then hand your team a review queue. Your team decides. We only auto-merge exact duplicates (identical email and name); we never guess-merge on a partial match.

Why this matters

Your outreach is only as good as your list. See which contacts are still real today and who looks to have moved on, so your team stops paying to reach people who have already gone.
