A technical glitch causing failed transactions can be a critical issue for customers, who might mistakenly believe their purchase was successful. Notifying these individuals via email is essential for good customer service and transparency. The central question is whether such a notification is considered a transactional email, particularly under regulations like Canada's Anti-Spam Legislation (CASL), especially if the recipients are not already subscribed to marketing communications.Generally, a transactional email is triggered by a specific user action or system event and contains information directly related to that action or event. The key differentiator for compliance, particularly with CASL, is the absence of commercial or promotional content. If the email solely informs the user about the failed transaction and guides them on how to resolve it without any marketing pitches, it typically retains its transactional status and is compliant.
Key findings
Primary purpose: An email about a failed transaction is primarily informational, correcting a user's misconception about a completed purchase. This aligns with the definition of a transactional email.
CASL compliance: Transactional emails are typically exempt from the consent requirements of CASL, provided they do not contain commercial electronic messages (CEMs). The content is paramount.
No promotional content: For the email to remain transactional, it must be devoid of any marketing or promotional content. Adding such elements could reclassify it as a CEM, subjecting it to CASL's consent rules.
User expectation: Users who attempted a transaction expect to be informed of its outcome, whether successful or failed. This expectation supports the email's transactional nature.
Key considerations
Content focus: Ensure the email focuses strictly on the failed transaction and any necessary steps for resolution. Avoid upselling, cross-selling, or calls to action unrelated to the immediate issue. If you're wondering what are the implications of including promotional content, remember it's primarily legal.
Wording: Use clear, concise language indicating a system error and how the user can retry their intended action. Do not make it appear as an abandoned cart reminder (which can be promotional).
Legal interpretation: Regulators look at the primary purpose of the email. If the email's core intent is to facilitate or inform about a specific user-initiated transaction, it is transactional. However, if it aims to promote a product or service, it becomes commercial email.
Unsubscribe link: Purely transactional emails are generally not required to have an unsubscribe link under CASL. However, if any promotional content is present, an unsubscribe mechanism becomes mandatory. Further information regarding marketing content in transactional emails can be found on Email Industries' guide on marketing in transactional emails.
What email marketers say
Email marketers often navigate the fine line between informing customers and triggering anti-spam regulations. In the case of a failed transaction notification, marketers generally agree that such an email is indeed transactional, provided its content is carefully managed to avoid any promotional overtures. The consensus leans towards prioritizing essential communication that directly relates to a user's interaction or system event, ensuring transparency and customer satisfaction without falling afoul of compliance laws like CASL.
Key opinions
Legitimate communication: Marketers view notifying customers about a failed transaction as a legitimate and necessary communication. Users expect updates on their actions, making these emails inherently transactional.
System error focus: The email should be framed as a system error message, conveying apologies and offering a path to resolution, rather than a sales pitch. This approach reinforces its transactional classification.
Implied re-purchase: While the message might implicitly invite the user to attempt the purchase again, its primary purpose is informational, not promotional. This nuance is crucial for compliance.
Context of engagement: Marketers emphasize that the email is a direct response to a user's action (the attempted transaction), which positions it as a transactional message that responds to their engagement.
Key considerations
Content purity: It is critical to ensure the email is entirely free of promotional content. Any attempt to upsell or cross-sell can immediately change its classification and compliance requirements.
Avoid abandoned cart perception: Careful wording is needed to prevent the email from being mistaken for an abandoned cart notification, which is typically marketing in nature.
Separate streams: Some marketers advise maintaining separate sending streams or practices for transactional and marketing emails to prevent deliverability issues. This helps separate transactional and marketing emails.
Legal interpretation: While transactional emails may not require unsubscribe links, the content's adherence to a strictly informational purpose is the ultimate determinant. For discussions on this, Quora discussions on transactional email rules provide insights.

What the experts say
Experts in email deliverability and compliance generally affirm that a notification about a failed transaction qualifies as a transactional email. Their perspective often centers on the email's primary intent: to provide necessary information related to a user's specific interaction with a service or product. They stress the importance of maintaining strict adherence to non-promotional content to ensure the email remains compliant with anti-spam legislation and avoids deliverability pitfalls that could lead to being flagged by ISPs or landing on a blocklist.
Key opinions
Legitimate and expected: Experts agree that notifying users of a failed transaction is a legitimate communication. Customers expect to know the outcome of their interactions, making this a necessary transactional message.
No explicit sales pitch: The message's transactional status is preserved as long as it avoids any explicit attempt to sell or promote. It should solely address the technical issue and its resolution.
User-initiated context: The fact that the email is a direct response to a user's attempted action reinforces its transactional nature. It's a follow-up on a specific interaction, not unsolicited outreach.
Strict content adherence: Experts strongly advise against any form of marketing or branding beyond what is strictly necessary for identification and communication of the transaction status. This is crucial for maintaining transactional status.
Clarity of purpose: The email's purpose must be unmistakably clear: to inform about a failed transaction and provide resolution. Any ambiguity could lead to it being classified as commercial.
Legal interpretation risk: While intent matters, legal bodies will scrutinize the actual content. Even subtle promotional elements can be enough to trigger compliance requirements for commercial messages.
Regulatory guidance: Consulting official guidelines and expert analyses on what constitutes transactional vs. marketing email is important. Ongage's blog on transactional emails offers further insights.

What the documentation says
Official documentation from various compliance bodies and email service providers clarifies the distinction between transactional and commercial emails, especially concerning anti-spam laws like CASL. These documents consistently emphasize that transactional emails are typically exempt from explicit consent requirements because they are necessary communications related to a user's action or account status. The critical element across all documentation is the absence of any promotional intent or content, ensuring the email serves a purely informational or facilitative role.
Key findings
Exemption from consent: Documentation confirms that transactional emails are often exempt from the consent requirements found in anti-spam laws like CASL, due to their essential nature.
Action-triggered: These emails are defined as automated messages triggered by a specific user action or event, such as a purchase attempt or account activity.
Non-promotional: A consistent theme is that transactional emails must not contain any marketing or promotional content to retain their exempt status.
Necessary communication: They are considered necessary communications that provide critical information to the recipient about a service or transaction.
Key considerations
Content review: Organizations must rigorously review the content of all emails to ensure they fall within the definition of transactional messages and do not inadvertently become commercial.
Compliance beyond consent: Even with consent exemptions, other aspects of CASL (e.g., sender identification) and other regulations (like CAN-SPAM) still apply to transactional emails. Following best practices for legally mandated notifications is crucial.
Jurisdictional differences: While general principles apply, specific requirements can vary by jurisdiction. Always refer to the laws applicable to your recipients.
Documentation from Mailchimp explains that CASL contains specific exceptions to the consent requirement for certain transactional messages. However, these messages still necessitate compliance with other sender requirements.It is vital to understand that while consent may be exempted, other aspects of the law, such as sender identification, must still be met.
