The email a compliance officer can defend.
RegNexus Mail authenticates every sender, seals every important message into a tamper-evident Trust Ledger, and files it to a matter under the right retention floor — SRA, FCA, ICAEW and more, built in. When anyone asks “show me,” you export the proof.
If anyone ever asks, what can you actually prove about this message?
Further to our supervisory engagement, please provide the complete correspondence record for the above matter, including evidence of receipt and authenticity, within 14 days of the date of this letter…
Every business has correspondence it can't afford to lose, misfile, or fail to prove — client emails, supplier invoices, contracts, sign-offs and approvals. RegNexus Mail turns all of it into organised, provable records.
Purpose-built for regulated firms — and a serious upgrade for any business that treats its email as records worth keeping. Regulated firms are simply the most demanding case; everything that protects them protects you too.
Nobody asks if you replied. They ask if you can prove it.
When correspondence is examined — by a client, a supplier, an insurer, a court, or a regulator like the SRA, the FCA, an ICAEW monitor or the Bank of Ghana — four questions decide whether it stands up. Standard email answers none of them.
- It can be edited after the fact
- It can be back-dated or reconstructed
- Its sender can be disputed
- Nothing guarantees it still exists when needed
- SHA-256 hashed on receipt — alteration breaks the chain
- Sealed with a timestamped block number
- Sender authenticated at receipt (SPF/DKIM/DMARC)
- Retained under the right floor for your business, automatically
Is it authentic?
Did this message really come from who it claims? RegNexus Mail authenticates every sender at receipt and records the result on the Communication Record.
Is it unaltered?
Could anyone have changed it since? Every message is SHA-256 hashed and sealed into a hash-chained Trust Ledger. Tamper with block N and the chain breaks from N forward — provably.
Is it on the record?
Is it filed where it belongs? Every important message is filed to a matter, or wears a magenta “Needs filing” badge until it is. Nothing important stays loose.
Is it retained lawfully?
Will it still exist when it's needed? Filed messages inherit the right retention floor automatically — 6 years SRA/FCA/ICAEW, 5 years fintech, a sensible default for everyone else.
Outlook and Workspace deliver mail. They were never built to answer these.
Six steps. Every important message. Automatically.
Good record-keeping fails when it depends on someone remembering. RegNexus Mail turns the discipline into a pipeline every important message runs through — no checklist, no chase.
The only step a person takes is filing. The evidence takes care of itself.
Tamper with one message, and the chain tells on it.
Every sealed message is written to a block, hash-chained to the block before it. Change any byte of a sealed message and every block from that point forward is invalidated — provably, publicly, in seconds. Try it.
The system knows your rules. So retention is never a decision.
When you file a message, RegNexus Mail already knows whether you're UK SRA-regulated law, an ICAEW practice, an FCA advisory, a general business, or a Ghanaian accountancy firm — and applies the correct retention floor automatically. Set a hold or a deadline on a matter once, and every message filed to it inherits the policy. No spreadsheet. No “we think it's six years.”
Hold a matter during a dispute or investigation and deletion is frozen across every message filed to it — legal hold is matter-linked, not a manual sweep.
“Show me.” — Two words you're now ready for.
When a client, a supplier, a regulator, or a court asks you to substantiate correspondence, you don't reconstruct it. You export it.

Your sector's vocabulary. Your jurisdiction's law. One codebase.
A matter in law is an engagement in accountancy, a case in financial advisory, and a project in any other business — and the regulator, the AML body, the data-protection law, the currency and the retention floor all differ by country. RegNexus Mail carries that knowledge as data, not as forked code. Nothing is white-labelled or bolted on.
