Compliance
Ensure email
data compliance
Protect data in line with regulatory guidance using the most secure email gateway.
GDPR - Encrypt personal information
MIFID II - Record proof-of-delivery
All businesses should record digital communications and retain proof-of-delivery to align with ICO guidance. Proof-of-receipt is also required by the FCA for certain types of document (e.g., KIDs). Mailock tracks every sent item - from delivery through to the exact date and time it’s opened by your recipient.
Consumer Duty - Protect customers
Are you encouraging customers to send their information into your business unsecured? The FCA's Consumer Duty is a mandate to provide easy-to-understand communications and protect customers from financial harm. Mailock makes it easy for you to delivery communications via your customers' channel of choice - email.
