Still using email to exchange sensitive client information?

While email still has utility as a general comms tool, its usefulness for managing client workflows, such as onboarding or collecting client data and documents, has long expired.

Version Control Nightmare

Exchanging multiple versions of documents buried in emails can result in confusion, leading to mistakes and delays.

Massive Time Suck

Trawling through emails results in lost productivity and wasted time trying to locate specific information or attachments.

Lack of Encryption

Emails are not encrypted by default, which means they can be intercepted and read by unauthorized individuals.

Loss of Control

You don’t have control over how it is forwarded, saved, or shared, which can result in unintentional exposure of data.

Attachment Vulnerabilities

Email attachments have the potential to contain harmful malware or viruses that could infect the recipients’ systems.

Risk of Fines & Penalties

With the rise in privacy and data protection fines and legal actions, handling client files and data securely is more important than ever.
