Business contacts are still personal data, so names, work emails and phone numbers need a lawful source and an easy unsubscribe. Event partners, webinar platforms and lead vendors often share lists, and the consent trail can get lost. Calls and SMS to Indian numbers also need TRAI compliance.
The first four things to sort out
Use only lead lists with a known consent source.
Keep a separate newsletter box on event and webinar forms.
Make unsubscribe work across email, calls and events within a day.
Check data terms with event partners and lead vendors.
A worked example
Marketing head (CMO)
A webinar lead list from an event partner
Day 1An event partner shares 2,000 registrant names and work emails.
Day 1Marketing asks what the registrants were told; the form named the partner only.
Day 2Only registrants who ticked a box to hear from the company are added.
AfterFuture co-hosted forms name both companies and have separate boxes.

Final list
Business contacts need a consent trail too.
What others in the sector usually do. Many B2B marketers start by cleaning old event lists that have no consent record.

8 questions the Marketing head (CMO) asks, answered in full
Short answer: Only with separate consent and an easy way to stop
Marketing needs consent that is separate and specific, unless the person clearly expects it from the relationship. Bought or scraped lead lists are risky because you cannot show consent. Every message should carry an easy way to stop.
From your seat: Marketing head (CMO). Every list needs a consent source you can show.
Example in IT and ITeS
B2B prospect lists still need a lawful source and an easy unsubscribe.
Short answer: It depends on the use; most organisations need both
For every use of personal data you need one basis: consent, or one of the legitimate uses in Section 7, such as a legal duty, employment, a medical emergency, or data a person gave voluntarily for a specific purpose. Anything beyond what the person expects, such as marketing, profiling or sharing with partners, usually needs consent.
From your seat: Marketing head (CMO). Ask marketing consent separately, by channel.
Example in IT and ITeS
Payroll and background checks are employment purposes. Newsletters to prospects need consent.
What the law says
Section 4 allows processing only with consent or for a legitimate use. Section 6 sets what valid consent looks like. Section 7 lists the uses that need no consent. Section 4 · Section 6 · Section 7
Steps
List each purpose for which you use personal data.
Against each purpose, write the basis: consent or the exact clause of Section 7.
Where the basis is consent, check that it was asked separately, with a clear action and no pre-ticked box.
Stop or re-paper any purpose with no basis.
Review the list whenever a new product, campaign or system starts.
Evidence to keep
Purpose and basis register
Consent records with date, version and channel
Legal sign-off on each legitimate use relied on
Common mistakes
Treating account terms as consent for marketing
Bundling several purposes in one tick-box
Relying on 'legitimate interest', which the Indian Act does not have
Short answer: Stop that use quickly, across every system and vendor
Withdrawal must be as easy as giving consent. Once someone withdraws, you and every vendor working for you must stop that use within a reasonable time. What was done before withdrawal stays lawful, and data that a law requires you to keep is kept.
From your seat: Marketing head (CMO). Make stop work across every channel and agency within a day.
What the law says
Section 6(4) to 6(6) give the right to withdraw at any time, with the same ease, and require processors to stop as well. Section 8(7) then asks for erasure unless a law requires retention. Section 6 · Section 8(7) · Rule 8 · Section 8(1)–(2)
Steps
Give one simple way to withdraw on every channel where consent is taken.
Record the withdrawal against the person and the purpose.
Push the change to every system and vendor that uses that purpose.
Confirm to the person, in writing, what has stopped and what is kept by law.
Check a sample every month to see that the change actually reached every list.
Evidence to keep
Withdrawal log with time stamps
Proof that downstream systems and vendors updated
Confirmation sent to the person
Common mistakes
Withdrawal by email only, while consent was one tap in an app
Stopping in the main system but not in vendor lists
Short answer: Check every channel; children often appear where you least expect
Anyone under 18 is a child under the Act. For a child's data you need verifiable consent from a parent or lawful guardian, and you must not track, behaviourally monitor or show targeted ads to children. Some classes and purposes are exempt under Rule 12 and the Fourth Schedule, for example healthcare to the extent needed to protect the child's health, and educational institutions for their educational work.
From your seat: Marketing head (CMO). No targeted ads to under-18s.
Example in IT and ITeS
Usually only if a client's service involves children, or in staff dependants' records.
What the law says
Section 9 sets the duties. Rule 10 explains how to verify the parent. Rule 12 and the Fourth Schedule list the exemptions. Section 9 · Rules 10, 12 · Section 6
Steps
Find where children's data enters: customers, dependants, interns, visitors, scholarships, app sign-ups.
Decide whether an exemption in the Fourth Schedule applies to that purpose.
Where none applies, add an age question and a parent-consent step.
Switch off tracking and targeted ads for under-18 users.
Record the decision for each channel.
Evidence to keep
Channel-by-channel note on children's data
Parent-consent records
Ad and tracking settings
Common mistakes
Assuming 'we are B2B, so no children'
Using the age 13 or 16 from foreign laws
Treating a tick-box from the child as parental consent
Short answer: Yes, within the purpose or with consent
Yes, where the use fits the purpose people were told, or you have consent for it. Improving the service people signed up for usually fits. Selling insights, profiling for third parties or targeting children does not. Mask or aggregate wherever the question allows, and give analysis copies their own deletion date.
From your seat: Marketing head (CMO). Tracking pixels and ad SDKs collect personal data; check the basis.
What the law says
Section 4 needs a lawful basis for each purpose. Section 6 needs specific consent. Section 9 bars behavioural monitoring of children. Section 8(3) asks for accuracy when data drives decisions. Section 4 · Section 6 · Section 9 · Rules 10, 12 · Section 8(3)
Short answer: Yes, at every point where you collect data
A notice must tell people, in plain words, what data you collect, why, how they can withdraw consent, how they can use their rights and how they can complain to the Data Protection Board. It has to stand on its own, separate from long terms and conditions, and be shown at the point where data is collected.
From your seat: Marketing head (CMO). Every landing page and contest form needs a short notice.
Example in IT and ITeS
Your careers page, candidate portal, employee onboarding and website forms need notices. For client data, the client gives the notice.
What the law says
Section 5 and Rule 3 ask for a notice that can be understood on its own, with an itemised list of the data and the purpose for each item. Data you already hold from before the Act also needs a notice, as soon as reasonably practicable. Section 5 · Rule 3 · Section 6 · Sections 11–14 · Rule 14
Steps
List every point where personal data comes in: forms, apps, counters, calls, emails, partner feeds.
Write one short notice per collection point, with the data items and purpose side by side.
Add how to withdraw consent, how to make a request and the DPO or contact person's details.
Offer the notice in English and in the languages your client customers actually use.
Keep each version with the date it went live.
Evidence to keep
Screenshots or copies of the notice at each collection point, with dates
Notice version history
Translations, where used
Common mistakes
Hiding the notice inside terms and conditions
One notice for everything, with no link between data items and purposes
Short answer: Yes, every vendor that touches personal data
You stay responsible for what your vendors do with personal data. The contract should say what data they get, for what purpose, the security they must keep, how fast they must tell you about an incident, that sub-contractors need your approval, and how data is returned or deleted at the end.
From your seat: Marketing head (CMO). Agencies and ad platforms need data terms.
Example in IT and ITeS
Sub-contractors working on client data need the same terms you signed with the client.
Short answer: Yes, with notice, a retention period and masking
Call recordings, chat transcripts and agent screens hold a lot of personal data. Tell callers that calls are recorded and why, keep recordings for a set period, limit who can listen, and mask card numbers and passwords on screen and in recordings.
From your seat: Marketing head (CMO). Telemarketing follows TRAI preference rules as well as DPDP consent.
Example in IT and ITeS
BPO call recordings must pause for card details and follow client retention rules.
Play a short recording notice at the start of calls.
Set a retention period by call type.
Pause recording when card or other sensitive details are given.
Limit replay rights to quality and complaint teams.
Lock agent screens and stop phones on the floor if data is sensitive.
Evidence to keep

Common mistakes
Recordings kept indefinitely

The sections you will use most
Section 5 · Rule 3: Notice. Candidate portals, employee onboarding and your own website forms need notices. For client data, the client normally gives the notice.
Section 6: Consent. Marketing to prospects and optional employee programmes need proper consent.
Report specified cyber incidents within six hours. Keep ICT logs for 180 days within India. Sync clocks to NIC or NPL time servers. Data centres, VPS, cloud and VPN providers keep specified subscriber information for five years.
Breach handling must meet the six-hour CERT-In clock and the DPDP report to the Board. Subscriber records need DPDP-level protection.
CERT-In
DPDP Act, Section 17(1)(d)
Processing of data of people outside India, under a contract with a party outside India, is exempt from most of the Act.
Tag each data set by where the people live. The exemption does not cover Indian staff or Indian customers.

IT Act, Section 43A and SPDI Rules, 2011
Reasonable security practices for sensitive personal data, until Section 43A is omitted on 13 May 2027.
Your current ISO 27001 practices meet these today; DPDP Rule 6 takes over from May 2027.
Commercial calls and SMS to Indian numbers must follow registration and preference rules.
Outbound campaigns for Indian clients need both DPDP consent and TRAI compliance.

Labour Codes (in force from 21 November 2025)
The four labour codes replaced older labour laws, including registers and records employers must keep.
Set retention for staff records against the new codes and state rules.

Client contracts and foreign laws (for example GDPR for EU clients)
Clients often bind you to their own country's law through contracts and standard clauses.
These are contract duties, not Indian law, but you must meet them alongside DPDP.
