Better Sharing Social Sharing vs. Email Invites
How to Minimize Risk by Encouraging Safe, User-Driven Sharing
When helping crowdfunding campaign creators promote their projects, platforms have two major options:
- Enable direct contact-based outreach (email invites)
- Empower social sharing (copy links, share to social media)
These approaches carry significantly different privacy implications and legal risks. Social sharing generally carries substantially lower privacy risk than emailing non-users, making it a preferable default strategy for most crowdfunding platforms.
This article compares both approaches and explains why user-driven, public sharing should be your platform’s primary promotion strategy from both a legal and user experience perspective.

Comparing Social Sharing vs. Email Invites
Different sharing mechanisms carry varying levels of privacy risk and regulatory implications:
| Method | Risk Level | Privacy Implications | Implementation Considerations |
|---|---|---|---|
| Social sharing (copy/paste links) | Very Low | No third-party data processed | Provide easy-to-copy campaign URLs with clear call-to-action |
| Share to Facebook, Twitter, WhatsApp | Very Low | Platform generates link; user initiates action | Implement native share integrations that use device/browser capabilities |
| Email invite via user’s email client | Low | User-driven; platform not involved in sending | Use mailto: links that pre-populate message content but send via user’s email app |
| Email invite via platform | High | Platform processes contact data and sends marketing communication | Requires consent mechanisms, opt-out functionality, and compliance with multiple regulations |
| Bulk email invites via platform | Very High | Platform processes multiple contacts and sends multiple messages | Significantly increases compliance burden and risk of spam complaints |
The key distinction is who controls the data processing and message sending. When users handle their own sharing, the platform’s legal responsibilities are significantly reduced. When the platform processes contact data or sends messages, it assumes substantial compliance obligations.
Why Social Sharing is Safer
Social sharing offers several key privacy and compliance advantages:
- No contact import needed: The platform never processes third-party personal data
- No matching or messaging non-users: The platform doesn’t send communications to individuals who haven’t consented
- No consent, transparency, or opt-out obligations triggered: Many regulatory requirements don’t apply when the platform isn’t processing contact data
- User handles the communication personally: The relationship remains between the creator and their contact, with the platform as a facilitator rather than an intermediary
- Reduced spam complaints: When users control sharing, messages are more likely to be relevant and welcome
This approach follows a core privacy principle: You don’t touch third-party data = You minimize legal risk. By empowering users to share on their own terms rather than processing their contacts, platforms can significantly reduce their compliance burden while still enabling effective campaign promotion.
Email Invites via Platform = Higher Risk
If your platform sends email invites on behalf of users, you assume several significant legal responsibilities:
- Data controller obligations: You must collect explicit consent to process contact information
- Message responsibility: You become legally responsible for the message content and delivery
- Anti-spam compliance: You trigger electronic marketing rules under GDPR, PECR, CASL, and CAN-SPAM
- Opt-out management: You must implement and honor unsubscribe mechanisms
- Data retention concerns: You need policies for how long contact data is stored
- Non-user rights: You must respect privacy rights of individuals who never signed up for your service
These obligations create a substantial compliance burden that many platforms underestimate. The convenience of platform-sent invites comes with significant legal responsibilities that require careful implementation.

Best Practices for Low-Risk Project Promotion
To enable effective campaign promotion while minimizing privacy risk, implement these strategies:
| Strategy | Best Practice | Implementation Guidance |
|---|---|---|
| Provide shareable links | Campaign URLs with easy copy buttons | Include one-click copy functionality and preview of what will be copied |
| Integrate native share options | “Share to Facebook”, “Share to WhatsApp”, “Tweet” | Use platform-native sharing APIs rather than custom implementations |
| Allow users to open mailto: links | Pre-fill an email draft in user’s email app—not platform-sent | Structure mailto: links with appropriate subject and body content |
| Encourage personalization | Enable users to customize messages | Allow users to add personal notes to shared content |
| Discourage mass invites | Avoid “Invite All” buttons that promote over-sharing | Design interfaces that encourage thoughtful, targeted sharing |
| Provide sharing templates | Offer suggested text for different contexts | Create templates that are personal and authentic, not marketing-speak |
| Track sharing, not contacts | Measure sharing actions, not recipient data | Focus analytics on share counts rather than tracking recipients |
These practices enable effective promotion while keeping the platform’s role focused on facilitation rather than direct messaging. This approach not only reduces legal risk but often leads to more authentic, effective sharing.
Real-World Example: GoFundMe’s Share Focus
GoFundMe provides an instructive example of effective, low-risk promotion strategies. The platform emphasizes:
- Personalized shareable links that creators can distribute through their preferred channels
- User-driven sharing through integrated social media buttons
- Campaign updates that notify existing backers who have already engaged
- Storytelling tools that help creators craft compelling narratives
GoFundMe deliberately avoids acting as a mass emailer, which reduces spam complaints and regulatory scrutiny. Instead, they focus on making campaigns highly shareable and providing creators with the tools to tell their stories effectively.
This approach has helped GoFundMe build a sustainable growth model that respects privacy while still enabling viral spreading of compelling campaigns. Their success demonstrates that platforms don’t need to process contact data directly to achieve significant growth. (Source)
Global Legal Standards for Sharing vs. Messaging
Different privacy regimes treat sharing and messaging differently:
| Region | Sharing Links | Sending Email Invites | Key Considerations |
|---|---|---|---|
| GDPR (EU/UK) | Low risk | Consent + transparency required | Email invites trigger both data protection and electronic marketing rules |
| CASL (Canada) | Low risk | Express consent for commercial messages | Very strict requirements for commercial electronic messages |
| CAN-SPAM (USA) | Low risk | Opt-out and sender identity required | Less strict than EU/Canada but still requires compliance measures |
| CPRA (California) | Low risk | Disclosure if data is shared or sold | Financial incentive notices may be required for referral programs |
| LGPD (Brazil) | Low risk | Similar to GDPR approach | Emerging privacy regime with comprehensive requirements |
The consistent pattern across jurisdictions is that user-driven sharing carries significantly lower compliance requirements than platform-sent messages. This makes social sharing a more scalable, globally compliant approach for most platforms.
Summary: Nudge Toward Sharing, Not Inviting
The most effective approach for crowdfunding platforms is to design for user-driven sharing:
| Practice | Outcome | Business Benefit |
|---|---|---|
| Make shareable links easy | More organic reach, lower legal risk | Reduced compliance burden with effective promotion |
| Offer social sharing buttons | User-driven promotion through established channels | Leverage existing social networks without data processing |
| Use user’s email client if needed | Platform stays out of direct messaging | Avoid triggering anti-spam regulations |
| Avoid mass platform-sent invites | Fewer compliance triggers, fewer complaints | Better sender reputation and reduced regulatory risk |
| Focus on content quality | More compelling, shareable campaigns | Higher-quality sharing leads to better conversion |
Let users drive outreach—and your platform can grow sustainably and safely. This approach not only reduces legal risk but often leads to more authentic, effective promotion that builds trust in your platform.
The key principles are simple but powerful:
- Empower, don’t coerce
- Share, don’t spam
- Facilitate, don’t intermediate
By following these principles, crowdfunding platforms can enable effective campaign promotion while minimizing privacy risk and regulatory exposure.
