Context

When viewing sequence previews in sequences or snippets, you may sometimes see a "Gathering data..." loading screen that persists for an extended period, or the preview may not load at all.

Answer

There are several common reasons why message previews may not load immediately:

For Sequences:

1. Paused Sequences: Content generation is paused when sequences are paused. The sequence needs to be briefly unpaused to generate previews.

2. Large Audiences: For sequences with many enrollments, previews may take additional time to generate. Check back in about an hour for recent enrollments.

3. Check the Outbox: You can often view message previews in the Outbox tab even if they're still generating in other views.

For Smart Snippets:

1. Missing Enrichment Data: If the snippet uses person-level data (like job title or work history) that isn't yet available, the system will show the fallback content instead of the personalized version.

2. Test Environment: When testing with example contacts (like "Sherlock"), the snippet may show the default fallback text since enrichment data isn't available.
