Operating requirements

Mailock works with any modern web browser on any device. As long as your browser is up-to-date, there is a good chance you can use Mailock.

To use our Outlook add-in, you need the classic desktop version of Outlook for Windows (see how to check).

This commonly comes with Microsoft 365 Business Standard subscriptions or higher tiers. Standalone copies like Office 2019 also work.

Our add-in works with any actively supported version of classic Outlook on any supported version of Windows (see Microsoft's end of support documentation).

Mailock Enterprise plan holders can use secure email with any mail flow through a number of integration options with our support.

Terms and conditions (incl. footnotes)

General terms

  • All prices exclude VAT.
  • Pro and Free plan users can reply to secure emails at no charge.
  • Message expiry periods vary by plan (see more in the FAQ item below).
  • Features, pricing, and capabilities for Enterprise plans (including identity checks and automated delivery) vary based on infrastructure, requirements, and the package negotiated with our team.

Footnotes

  1. Mailock Pro is designed for normal secure email use by individuals and businesses. To protect the service for all users, fair usage controls apply to unusually high-volume, automated, or broadcast messaging activity unless this has been expressly agreed by contract. See our Acceptable Use Policy for more information.
  2. Mailock Pro includes 25 SMS authentications per licensed user per month. Additional SMS packs can be purchased if needed. SMS authentication is also available on Enterprise according to your package. See our Acceptable Use Policy for more information.
  3. Identity checks (IDV) are available subject to business approval and confirmation that your organisation meets the required data handling, compliance and security standards. On Enterprise, availability depends on your agreed package/contract. Support on Pro is coming soon.

Our End User Agreement and Acceptable Use Policy apply to all plans.

FAQs

When do messages expire?

Secure email data is stored for a specific time period before it expires. This time period is based on the sender's Mailock plan.

Recipients can easily download a copy of a secure email and save it before it expires.

Expiry periods are as follows:

  • Mailock Free accounts are limited to 21-day message expiry.
  • Mailock Pro accounts are limited to 365-day message expiry
  • Enterprise and Automated accounts have at least 365-day message expiry.

What is a recipient challenge?

Recipient challenges allow you to verify your recipients are the right people before they gain access to the secure emails you send them.

Mailock users can set a variety of challenge types for recipients, including:

  • Q&A: Set a question unique to your recipient that they must correctly answer.
  • SMS: Input your recipients' phone number to send a code to their mobile device.
  • Unipass ID: Let financial professionals sign in with their Unipass ID, the identity they already use across financial services.
  • ID&V: Request a document check using a passport or utility bill and driving licence (coming soon!).

What is the Outlook add-in?

The Mailock Outlook add-in for Windows adds secure email to your desktop.

Installing the Mailock Outlook add-in will enable the following features in your email client:

  • Compose secure emails
  • Set recipient challenges
  • Track sent messages
  • Revoke sent messages
  • Surface alerts for sensitive content
  • Auto-decrypt inbound secure emails

What is Unipass Identity?

Unipass ID is a virtual pass that enables professionals to log on to multiple financial services platforms.

Linking your Unipass ID with your Mailock secure email account means you can use the same login method that you use on other financial services platforms to verify your identity on the Mailock network.

As Unipass ID is a professionally registered identity, Mailock users can also choose to "trust" others who have linked their Unipass ID when they send them secure emails.

What are trigger words?

All new Mailock accounts contain our preset list of trigger words that, if present in an unsecured email, will surface an alert asking you if you want to send a message securely.

Examples of these words include:

  • 'Confidential'
  • 'Sensitive'
  • 'Investment'

With a Pro or Enterprise account, you or your company administrator can edit this preset list of trigger words to reflect your security policy.

What is the message tracker?

Mailock tracks your secure emails and provides you with a timestamped log of delivery and activity, including:

  • Message access
  • Challenge attempts

The message tracker is available to view on the web or in Windows Outlook using our add-in.

What is automated bulk send?

Mailock Automated is an optional add-on to Mailock Enterprise that enables bulk delivery features for scaled customer communications.

With Mailock Automated, you can batch and deliver sensitive communications at high throughput.

It is optimal for statements or other documents that need to be sent out regularly to a large audience of customers.
