Client correspondence you can stand behind.
Accountancy practices handle sensitive financial data across client communications every day. RegNexus Mail turns that correspondence into organised, provable records — authenticated senders, sealed messages, and engagements with the ICAEW retention floor already applied.
Data integrity and client trust, by construction.
Encrypted transport, automated backups and archiving purpose-built for professional services — not bolted on from five vendors.
Everything files to an engagement
In accountancy a matter is an engagement. Correspondence, invoices and approvals file against the engagement they belong to, and inherit its retention floor automatically.
Retention applied for you
The platform knows you're ICAEW-regulated and applies the 6-year floor without a spreadsheet or a “we think it's six years”. Holds freeze deletion across an engagement in a click.
Financial data, sealed and unaltered
Every important message is SHA-256 hashed on receipt and sealed into a hash-chained Trust Ledger. Alter one sealed message and the chain breaks from that point — provably.
Evidence packs on demand
Export a certificate of receipt and authenticity for a single message, or a full evidence bundle for an engagement — ready for a client, a dispute or a monitoring visit.
Zero-downtime migration. Move from legacy hosting providers with guided DNS onboarding, so your domains are properly configured — SPF, DKIM and DMARC — from day one.
Deliverability that protects your reputation. Daily DNS health checks and deliverability monitoring keep client statements and reminders landing in the inbox, not the spam folder.
Your practice website, same platform. Host it alongside your email with auto-SSL, daily backups and uptime monitoring — no separate hosting provider to manage.
Let every engagement answer before it's asked.
Follow one message from receipt to sealed evidence, then verify it on the public page.
