2

Embed in Email

Insert image in pre-event email or invitation:
  • “Get ready for [Event Name]! Scan this QR code at the event to create your AI photo.”
3

Include Direct Link Too

Some email clients don’t display images well, so include text link: app.metalabia.com/?event=[your-slug]

​
Social Media

  • Post QR image on Instagram Stories with “Swipe Up” (if available)
  • Share on Facebook event page
  • Tweet QR before/during event
  • Add to LinkedIn event posts

​

  • Provide download link for guests to save

​
Presentation Slides

For conferences or corporate events:
  • Include QR on last slide of presentations
  • Display on loop during breaks
  • Project on screens during networking

​
Using Direct URL Instead of QR

If QR codes aren’t feasible, share the direct URL: Your Event URL: 
app.metalabia.com/?event=[your-event-slug]
Where to Use:
  • Text messages to guests
  • Social media posts
  • Email signatures
  • Verbal announcements (“Visit app dot metalabia dot com slash events slash [slug]”)
Pros of URL:
  • Works in all contexts (digital and verbal)
  • Can be bookmarked
  • Easy to type
Cons of URL:
  • Longer than scanning QR
  • Risk of typos
  • Less immediate than scan
Best Practice: Use QR codes for in-person events, and direct URLs for digital promotion.

Solutions:
  • Verify QR points to correct URL (ask partner)
  • Have partner check event status
  • Top up credits if needed
Causes:
  • Venue WiFi issues
  • Mobile data connectivity
  • Event URL malformed
Solutions:
  • Ensure venue has strong WiFi (provide password)
  • Test with multiple phones in different areas
  • Share direct URL as backup
Cause: Partner generated QR before you updated branding in dashboard.Solution:
  • Update branding in your dashboard and save
  • Ask partner to regenerate QR code
  • New download includes updated logo/colors
Workaround: Use free QR generator online:
  1. Go to qr-code-generator.com or similar
  2. Enter your event URL: app.metalabia.com/?event=[slug]
  3. Generate and download
  4. Won’t have custom branding but will work
Note: For official/branded version, still request from partner later.
