Email Marketing Compliance and Best Practices

TRAI’s Unsolicited Commercial Communications framework requires businesses sending bulk commercial email to Indian recipients to register as principal entities, obtain verifiable consent before sending promotional communications, respect Do Not Disturb preferences, and maintain auditable consent records. Non-compliance exposes businesses to complaints, penalties, and suspension of bulk sending privileges.

The IT Act governs data collection, storage, and usage for electronic communications in India. Key obligations include obtaining informed consent before collecting subscriber data, maintaining reasonable security practices, and giving subscribers meaningful control over their personal information.

India’s Digital Personal Data Protection Act (DPDPA) will significantly raise the bar when it comes fully into force, introducing stricter consent requirements, mandatory breach notification timelines, and stronger individual data rights. Businesses that build compliant programs now will transition smoothly. Those who do not will be scrambling to catch up.

We stay ahead of these developments and update our practices accordingly, so our clients are never caught off guard by a regulatory change.

GDPR applies to any business that sends emails to people in the EU, regardless of where the sending business is located. If you have EU subscribers on your list, you must comply with GDPR.

The core requirements: free, specific, and unambiguous consent prior to the sending of any marketing email; documented consent that can be produced on request; a clear and immediate unsubscribe mechanism in each email; and complete respect for data subject rights, including the right of access, rectification, and erasure.

Failure to comply with GDPR can result in penalties up to €20 million or 4% of global annual turnover. The practices GDPR requires are good email marketing practices, no matter where you are in the world, which is why we treat GDPR as a global standard, not a European problem.

Many business senders are surprised to learn that CAN-SPAM covers commercial email to US recipients and includes both B2B email and consumer campaigns. Requirements include honest and non-deceptive subject lines, a valid physical postal address in every email, a clear unsubscribe mechanism, and unsubscribe requests honored within 10 business days.

CAN-SPAM isn’t as strict as GDPR, but it does have real penalties for non-compliance, and its honesty requirements for subject lines are ones we hold ourselves to on every campaign we run, no matter where the recipient is.

CASL is one of the most stringent email marketing laws in the world. This means that you need express or implied consent before sending any commercial electronic message to a Canadian recipient. You need to clearly identify yourself as the sender in each message. And you need to have an unsubscribe mechanism that works and is honored within 10 business days.

Critically, CASL shifts the onus of proof from the recipient to the sender to establish the existence of valid consent. CASL does not allow for optional consent documentation records. They are your defense at law.

We look at how a client’s list was built before we ever send an email on their behalf. Any segment that can’t show verifiable consent is flagged and removed until it can be properly re-permissioned. We want to mail a smaller opt-in list, not a larger non-opt-in list.

Before any campaign launches, we validate and properly set SPF, DKIM, and DMARC records. We don’t guess; we verify. For new sending domains, we manage IP warm-up schedules that gradually and safely build sender reputation before high-volume sends start.

Hard bounces are taken out right after each campaign. Soft bounces are tracked and handled above set thresholds. Inactive subscribers are identified on a rolling basis and either moved into a re-engagement flow or suppressed before they begin to negatively impact engagement metrics and future deliverability.

When a subscriber clicks unsubscribe, they are instantly taken off the active list. No time wasted. No re-subscription loop. No dark pattern that makes it harder than it should be to opt out. We build suppression lists and apply them to all sends, without exception.

We monitor complaint rates on Google Postmaster Tools, Microsoft SNDS, and other inbox provider reporting tools. Once we reach an acceptable threshold, usually 0.08% for Gmail, we pause the campaign segment, diagnose the cause, and implement corrective measures before the issue escalates.

The law of email marketing is not fixed. TRAI updates its framework, GDPR guidance changes, and India’s DPDPA implementation is ongoing. We monitor these changes and proactively update our compliance practices so that our clients are prepared for regulatory developments, rather than waiting to respond to changes after they have already created risk.

We begin with the list itself. Where did the contacts come from? How was consent obtained? Are there segments where the source of consent is unclear or unprovable? We sort the list by the quality of consent and mark any segments that need to be re-permissioned before they can be safely mailed.

We look at the bounce rates, open rates, click rates, and complaint rates of past campaigns. This analysis tells us the present health of the list, how inbox providers are treating the sending domain, and where the most urgent hygiene work needs to happen.

We check each client’s sending domain and subdomain for SPF, DKIM, and DMARC records. Any misconfigured or missing authentication records are corrected before any campaign is launched. We also check BIMI records for customers who want their brand logo in the inbox—a trust signal that’s becoming increasingly important for high-volume senders.

We verify the client’s sending IPs and domains against major blacklists: Spamhaus, Barracuda, MXToolbox, and more. If an IP or domain is blacklisted, it must be remediated prior to sending resumes. The remediation process varies based on the blacklist and the reason for the listing.

We ensure that the unsubscribe functionality works correctly for all active campaigns and that suppression lists are complete and applied consistently. Gaps in suppression list management are one of the most common compliance exposures we see in inherited email programs.

We audit the client’s email content, consent documentation, and sending practices against the regulatory frameworks that apply to their audience—TRAI, the IT Act, GDPR, CAN-SPAM, or CASL, depending on where their subscribers are located. We document and address any gaps before we take over campaign management.

We use Google Postmaster Tools, Microsoft SNDS, and other inbox provider reporting systems to assess the client’s current sender reputation score, spam rate trends, and domain reputation status. This provides a baseline against which we can measure improvement as compliant sending practices are implemented.

At the end of the audit, we provide a clear written report on what we found, the risk level of each issue, and the remediation steps we recommend (including the prioritized action plan and timeline). No jargon, no vague recommendations, just a clear picture of the program’s status and exactly what needs to happen next.

The audit usually takes between five and seven working days, depending on the size and complexity of the existing program. For most clients, it uncovers issues they didn’t know they had and provides a clear platform to build a program that performs consistently from day one.
