Lead Nurturing vs Lead Generation
This guide clarifies the critical distinction between first-party lead nurturing (allowed) and third-party lead generation (restricted/prohibited) for A2P 10DLC registration.
Understanding the distinction
Note
Key principle: The brand sending messages must be the same brand the consumer gave consent to. If there is any intermediary between the consumer's consent and the message sender, the campaign is classified as lead generation.
| First-party lead nurturing | Third-party lead generation | |
|---|---|---|
| Definition | Messaging people who gave consent directly to your brand | Collecting contacts and selling/sharing them with other businesses |
| Consent source | Your own form, website, or interaction | Aggregator sites, affiliate networks, purchased lists |
| Who sends? | The brand the consumer opted in to | A different brand than the one the consumer interacted with |
| Registration outcome | Approved (with proper opt-in) | Denied – not eligible for resubmission |
What's allowed (first-party lead nurturing)
Businesses that collect their own leads and message those leads directly may register campaigns for:
Follow-up on inquiries – Responding to form submissions, quote requests, demo signups
Drip campaigns – Scheduled educational or promotional sequences to opted-in contacts
Re-engagement – Reaching out to inactive customers who previously consented
Appointment scheduling – Confirming or reminding about scheduled consultations
Event follow-up – Post-webinar or post-event messaging to attendees who opted in
What's prohibited (third-party lead generation)
The following activities are not permitted on A2P 10DLC:
| Prohibited activity | Why |
|---|---|
| Selling or sharing opt-in lists with other businesses | Consent is non-transferable between brands |
| Messaging contacts acquired from lead aggregator sites | Consumer did not consent to your brand specifically |
| Affiliate marketing via SMS | Promoting third-party products/services to your list |
| Co-registration (bundled consent for multiple brands) | Each brand must obtain its own separate consent |
| Messaging contacts from purchased databases | No direct consent relationship exists |
| Operating as a lead-gen intermediary | Brand sending must be the brand that collected consent |
Campaigns involving these activities trigger permanent denials that are not eligible for resubmission.
Common denial reasons
The following denials are triggered when lead generation or affiliate marketing is detected:
Note
Non-compliant brand affiliation – Brand associated with or website indicates that message content contains the following which is considered restricted or disallowed by mobile operators: Lead generation or affiliate marketing.
Note
Campaign non-compliant content: affiliate marketing – Campaign use case indicates that message content contains one or more of the following which is considered restricted or disallowed by mobile operators: Lead generation or affiliate marketing.
Note
Campaign flagged as spam or phishing – The Privacy policy or Terms associated with the campaign may indicate that SMS opt-in consent or phone numbers are being shared with third parties or affiliates. This campaign is not eligible for resubmission.
Note
Invalid brand business connection – Brand is an ISV or Reseller and not the content provider. The brand that is registered should be the end brand, such as the business whose name is in the message content and who the end user believes to be sending the message.
Red flags that trigger lead-gen denials
Reviewers look for these signals in your registration:
Website contains language about "connecting you with partners" or "our network of providers"
Privacy policy mentions sharing phone numbers or consent with third parties or affiliates
Campaign description references multiple brands or "on behalf of" language
Brand is a marketing agency or platform registering under its own name rather than the end brand
Message samples reference a different company than the registered brand
Opt-in form collects consent for multiple unrelated services simultaneously
How to register correctly as a lead nurturer
If you are a legitimate first-party business that nurtures your own leads:
Register as the end brand – The brand name must match who the consumer believes is messaging them
Own your opt-in – Consent must be collected on your own properties (website, app, in-store)
Match brand to messages – Message samples must reference your registered brand name
Clean your privacy policy – Remove any language about sharing consent or phone numbers with third parties
Describe your flow clearly – Campaign description should state "We message people who submit inquiries on our website" not "We connect consumers with service providers"
Compliance checklist
Before submitting your registration, verify:
You are the end brand – Not a marketing agency, aggregator, or intermediary
Consent is first-party – Collected directly by your brand on your own properties
No consent sharing – Privacy policy does not mention sharing opt-in data with third parties
Brand matches messages – Your registered brand name appears in message samples
No affiliate language – Website and campaign description contain no references to partner networks, lead distribution, or affiliate programs
Single-brand consent – Opt-in form collects consent for your brand only, not bundled with others
Campaign description is specific – Clearly states what messages you send and to whom (your own customers/leads)
If you were denied
If your campaign was denied for lead generation or affiliate marketing:
Audit your website – Remove any language suggesting you share leads, connect consumers with partners, or operate an affiliate network
Update your privacy policy – Ensure it explicitly states you do not share opt-in consent or phone numbers with third parties
Revise campaign description – Describe only your direct relationship with the message recipients
Verify brand alignment – Confirm the registered brand is the same entity consumers see in messages
Note
Note: If your business model fundamentally involves collecting leads for other businesses, this use case is not eligible for A2P 10DLC regardless of how the registration is worded. Consider whether your messaging program can be restructured so that each end brand registers and messages independently.
