Compare the plansSwitch & save
The household names charge per user, per envelope, per feature. They hold your documents on servers an ocean away. MySign gives you the same legally binding signatures and the same workflows for one flat price per plan, never per seat.
Still printing and scanning? Even better. Your first send takes about five minutes.

Integrations & AI
Connect MySign to the tools your business already runs on: CRM, accounts, storage, chat. And because we ship a Model Context Protocol (MCP) server, your AI assistant can prepare, send and chase contracts for you.
Don't see your stack? Webhooks and Zapier cover most of it. If they don't, tell us what you need.
New · MCP server
Connect Claude, Copilot or any MCP-compatible assistant to MySign. Your AI fills the template, addresses the envelope and reports back when it's signed, while you get on with real work.
Assistants act through API keys you issue and revoke, and every envelope they touch keeps its full audit trail.

Questions
Anything else? A real person at [email protected] will get back to you, usually the same day.
Here's the straight answer. You're never billed per user. You pick a flat plan instead. Starter (£9.99/mo) covers one person. Pro (£63.99/mo billed annually) covers teams of up to five for one price, whether one of you sends or all five do. "Five" means five sender logins. The people you send documents to never need an account or a seat. More than five senders? Enterprise (£239.99/mo billed annually) is sized to your team. Still one flat price, still no per-seat maths.
Yes. Electronic signatures are legally recognised in the UK under the Electronic Communications Act 2000 and UK eIDAS. Every MySign envelope comes with a sealed audit certificate recording who signed, when, where and how. That's the evidence that matters if a signature is ever challenged.
A few document types still have special rules: deeds that need a witness, some HM Land Registry forms, wills and certain family-law documents. Most day-to-day business paperwork (contracts, engagement letters, offers, tenancy agreements) is fine. We'd rather tell you that plainly than find out you learned it the hard way. Our UK compliance page has the details.
Most teams switch in an afternoon. Your templates are just Word or PDF files. Upload the same ones you use today, place your fields once, and you're sending. Documents you completed on your old provider stay valid (they're standard PDFs you keep), so there's nothing to migrate and no overlap period to pay for.
Always. Completed documents and their audit certificates are standard PDFs you can download at any time. They're yours, not ours. Cancel whenever you like; your signed documents remain legally valid forever.
In the United Kingdom, full stop. Documents are encrypted in transit and at rest, held in UK data centres, and governed by UK law and UK GDPR. Your contracts never make a transatlantic round trip. The full detail lives on our UK compliance page.
No. Signers get a secure link by email and sign in their browser on any device. No downloads, no registration, no passwords to forget. Most people finish in under two minutes.
Yes. Individual accounts get a 7-day free trial when they sign up, and every plan is cancel-anytime with no lock-in and no leaving fees, so trying MySign never traps you. Your documents stay yours to download whatever you decide.
Starter includes 10 signatures a month, right for occasional signing. If you're regularly sending more, Pro gives you unlimited standard signatures for £63.99 a month, and upgrading takes one click from your dashboard. No overage fees, no surprises on the invoice.
Yes. MySign ships a Model Context Protocol (MCP) server, so assistants like Claude and Copilot can prepare envelopes, fill templates and check signing status on your behalf. Assistants act through API keys you issue and revoke, and every envelope they touch keeps its full audit trail. MCP, the REST API and webhooks are part of the Enterprise plan.
