Frequently Asked Questions ( F.A.Q. )

What is SigMail?

SigMail is a secure encrypted HIPAA, PHIPA compliant next-generation messaging system allowing physicians, healthcare institutions, pharmacies, patients and other healthcare service providers to communicate in a secure and encrypted manner, while protecting confidential records and patient information. SigMail is compatible across all platforms and we have given considerable attention to user experience while designing the journey between healthcare service providers and patient by minimizing clicks and following Web Content Accessibility Guidelines (WCAG 2.1) and Accessibility for Ontarians with Disabilities Act (AODA) guidelines. SigMail is for everyone who care about the privacy of their personal data.

How does it work?

Healthcare providers will be allowed to setup a SigMail account via their clinics / institutions and may create accounts for each one of their patients. Patients utilize the SigMail secure messaging platform to email their doctor or those defined within their circle of care.

SigMail allows physicians to exchange home monitoring results (blood pressure, EKG strips, heart rates, oxygen levels, etc.), lab requisitions/ testing requisitions securely protecting patient health information.

What is wrong with my fax machine for sending PHI?

The fax machine is an unreliable, inefficient and dated way to communicate with a huge potential of Personal Health Data (PHI) being exposed to those in a Doctors office. Furthermore, fax transmittals are counterintuitive to the digital mandate of the modern Doctor and medical systems.

How does the use of secure email benefit my medical office?

The average medical office receives over 50 phone calls per Physician per day. Most of these enquiries can be handled more efficiently in an asynchronous fashion utilizing secure and encrypted email. SigMail can help patients with reduced mobility, save clinic wait and travel time by providing a secure platform for Physician Patient communication thus minimizing unnecessary face to face visits.

Where does my data reside and is it protected against cyber attacks?

Your data resides in Canada behind 5-levels of security and our datacenters are ISO 27001, PCI and SOC 2 certified, as required by HIPAA, PHIPA and PIPEDA guidelines. We protect your personal and health information data: at rest, in transit and on the network.

Why can't I use regular email to email my patients or other healthcare providers?

Many have the impression that e-mail travels from one computer to another. E-mail communication works so that the users utilize mail servers that transfer, store and send messages with different client programs. Mail servers in turn transfer messages through other mail servers and different proxy servers to receiver’s mail server. Receiver reads the message from the mail server with the client program in use like Gmail, outlook, yahoo etc. Thus, e-mail passes through multiple servers, not directly from computer to computer. Messages are perfectly readable when they travel unprotected.

The Information and Privacy Commissioner of Ontario has stated in 2016 that the PHIPA requires the use of encryption, stating, “The IPC expects that email communication of personal health information among custodians will be secured from unauthorized access by use of encryption” and “custodians should use encryption for email communication with patients.” Regular email is not secure and its use exposes healthcare providers to significant risk.

What is end-to-end encryption?

End-to-end encryption involves information being encrypted between any two users on the internet and encrypted while being stored on computer servers.

SigMail message exchanges are protected with an end-to-end encryption protocol making it impossible for third parties, including SigMail service providers to read or examine. These messages can only be decrypted by the intended recipient. Attachments to your email message such as images, home monitoring results (blood pressure, EKG strips, heart rates, oxygen levels, etc.), lab requisitions/ testing requisitions, video, or audio are all encrypted in the same manner.

How does SigMail manage the privacy of my data?

Privacy is embedded into the design and architecture of SigMail, to deliver maximum degree of privacy and ensuring your personal data is automatically protected. Privacy is not selected as an add-on to SigMail making it an essential component of the core functionality without diminishing functionality.

How does SigMail protect our data from cybercrime?

Our platform provides secure connectivity on the internet to our users. Data is protected on network, in-transit and at rest. Our data resides in Canada in our datacenter which is ISO27001, PCI and SOC 2 compliant. We have best in class physical security in our datacenter We strictly follow HIPAA, PHIPA and PIPEDA guidelines to protect the privacy and security of our patient data.


The Health Insurance Portability and Accountability Act (HIPAA) is the Standards for Privacy of Individually Identifiable Health Information, commonly known as the HIPAA Privacy Rule, establishes the first national standards in the United States to protect patients’ personal or protected health information (PHI).

In Canada, the Personal Health Information Protection Act (PHIPA) is an in-depth piece of legislation designed to address very complex issues concerning the collection, use and disclosure of personal health information by health information custodians.

The Personal Information Protection and Electronic Documents Act (PIPEDA) is a Canadian law relating to data privacy. It governs how private sector organizations collect, use and disclose personal information in the course of commercial business.
