DPDP Action Sheet
Use this before your next workflow goes live. It keeps the useful parts visible and turns DPDP into checks your team can actually answer.
For DPDP WhatsApp Marketing Guide, the DPDP question is how personal data enters the workflow, where it is stored, which tools touch it, what purpose was explained, and how deletion or withdrawal will work.
1. Lead Forms
Check:
- What data are you collecting?
- Is the purpose clear at the point of collection?
- Is marketing consent separate from service communication?
- Can the user withdraw consent later?
Common mistake: one checkbox that silently covers newsletters, sales calls, partner sharing and remarketing.
2. Email and WhatsApp
Check:
- Who is on the list?
- Where did consent come from?
- Is the list imported from a vendor, event, webinar, scrape or old CRM?
- Can you prove the source of consent?
Common mistake: treating every lead as permanently marketable.
3. Ads and Retargeting
Check:
- Are pixels or ad platforms receiving identifiable user behavior?
- Are audiences built from customer lists?
- Are lookalike or remarketing audiences using personal data?
Common mistake: assuming "the ad platform handles it" means your company has no DPDP responsibility.
4. Website Analytics
Check:
- Which tools run on the site?
- Are IP address, device identifiers, session IDs or form fields being captured?
- Is analytics used only for measurement, or also for profiling and targeting?
Common mistake: installing tools first and asking privacy questions later.
5. Vendor List
Make a quick list:
- CRM
- Email platform
- WhatsApp provider
- Analytics
- Ad pixels
- Form tool
- Landing page builder
- Webinar tool
For each vendor, answer: what data goes there, why, who can access it and how deletion works.
6. This Week's Action
Map one campaign from first click to final follow-up. Mark every place personal data is collected, enriched, shared, uploaded or used for targeting.
If your team cannot answer where the data came from and where it goes next, start with a data flow map before rewriting policy copy.

WhatsApp broadcasting relies on phone numbers and profile information. Under DPDP, these are personal data points that require specific management. Marketing messages sent via WhatsApp Business APIs require verifiable consent that is separate from transaction alerts like shipping updates or OTPs.
Specific Consent for WhatsApp
DPDP requires affirmative action for marketing. You cannot assume consent because a customer shared their number during a purchase. If you use a checkbox on your website, it must be unchecked by default. For existing databases, if the original consent did not explicitly mention WhatsApp marketing, you cannot start broadcasting to those numbers without a fresh opt-in.
Managing Opt-outs and Data Processors
DPDP mandates that withdrawing consent must be as easy as giving it. A “Type STOP to unsubscribe” feature is a technical requirement. Your back-end system must sync this response immediately with your master marketing list. Additionally, most companies use third-party platforms to send bulk messages. These platforms are Data Processors. You must have a contract ensuring they do not use your customer numbers for their own analytics or share them with other brands.
WhatsApp Workflow Risks
| Activity | Data Involved | DPDP Risk Level |
|---|---|---|
| Bulk Broadcasting | Phone numbers, opt-in timestamps | High |
| Automated Support | Shared documents, live location, images | Very High |
| Campaign Tracking | Click-through rates, profile names | Medium |
| Audience Segmentation | Purchase history, interest tags | High |
| Chat Backups | Entire conversation history, media files | High |
This week
Audit your WhatsApp Business automated greeting. Ensure the message includes a clear instruction or a button that allows users to withdraw their consent or access your privacy notice.
Now think about your work. Where does personal data enter your workflows? Where does it sit? Who else touches it?
Frequently asked questions
Can I use my existing customer phone list for WhatsApp broadcasts?
Only if those customers gave specific consent for WhatsApp marketing. Using numbers collected for billing or delivery to send promotional broadcasts violates purpose limitation rules under DPDP.
Do I need to store proof that a user opted in via WhatsApp?
Yes. You must maintain a log showing when and how the user agreed to receive messages. This record serves as your evidence if a customer or regulator questions your right to process their data.
What happens if a user types STOP in a chat?
You must treat this as a formal withdrawal of consent. Your system must immediately stop all marketing messages to that number and update your database to reflect the withdrawal date.
