Part 2: From Awareness to Action – How to Audit for CASL Compliance in 2025
In Part 1, we made the case that email marketing today is about quality, not quantity. We talked about how engagement metrics, not just list size, are the real indicators of success, and why CASL compliance is not just a checkbox but a foundation of trust and performance.
Now let’s take it a step further.
Because here’s the reality: a lot of marketers are handed the job of “making sure we’re CASL compliant” without leadership fully grasping what that entails. And it is not a light lift. Most organizations dramatically underestimate the time, effort, and cross-team coordination needed to audit and update their CEM practices properly.
That’s where this blog comes in.
We’ll walk through two key pieces:
- A quick recap of CASL’s historical milestones and how enforcement has evolved
- A sample audit timeline using a sprint-based approach, tailored to the size and structure of your organization
If you love sprint planning like I do, you’ll appreciate how breaking a CASL compliance project into manageable chunks can turn something overwhelming into something actually achievable.
A Look Back at How CASL Has Evolved
Understanding where CASL started and where it has tightened over time helps explain why compliance today is more than just a quick legal review or a one-time email footer update.
July 1, 2014: CASL Officially Came Into Effect
- Obtain valid consent (express or implied)
- Clearly identify the sender
- Include a working unsubscribe mechanism
July 1, 2017: End of the Transitional Period
- Implied consent was subject to clear expiry rules (2 years from a purchase, 6 months from an inquiry)
- Express consent became the gold standard
- Legacy contacts with no valid, provable consent had to be removed
2017 to 2021: No Major Rule Changes but More Enforcement
- More fines and investigations
- Higher expectations for audit-proof consent records
- Increased scrutiny on signup forms, pre-checked boxes, and ambiguous language
CASL Expectations in 2021 and Beyond
If someone had been on your list since the early days but you had no record of their consent, continuing to message them put you at legal risk.
So if you still had pre-2014 contacts hanging around in 2021 without documented consent, you should have either re-permissioned them or let them go.
Quick Reality Check
If you are still emailing people who joined your list before 2014 and you don’t have clear documentation of when how they gave consent, it’s time to let them go or plan to run a re-permission campaign immediately.
No consent record = no send.
It doesn’t matter how long they’v been receiving your emails. If you can’t prove compliance, the risk now outweighs the reward.
