How people build group cards together
Original, privacy-safe aggregate findings about group card participation on Sharewell from 1 January through 30 June 2026.
The typical active card received 12 messages
Across 2,201 eligible cards, 1,593 received at least one valid contribution. Among those active cards, the median was 12 messages and the mean was 14.5.
Most active cards moved beyond a handful of signatures
The 90th-percentile active card received 30 messages. To keep abandoned creations visible in the analysis, the table also reports message counts across every eligible card, including cards with zero contributions.
| Measure | Value | Population |
|---|---|---|
| Eligible cards | 2,201 | Non-deleted cards created in the analysis period |
| Cards with at least one contribution | 1,593 (72.4%) | Eligible cards |
| Valid messages | 23,108 | Non-deleted messages posted on or after card creation |
| Mean / median messages per created card | 10.5 / 8 | All eligible cards, including zero-message cards |
| Mean / median messages per active card | 14.5 / 12 | Cards with at least one valid message |
| 90th percentile, active cards | 30 | Cards with at least one valid message |
| Median / 75th percentile time to first contribution | 0.5 / 8.9 hours | Cards with at least one valid message |
| Messages containing a photo | 3,622 (15.7%) | Valid messages |
Farewell, retirement, and birthday cards led named occasions
Occasion labels are user-entered and multilingual, so they were grouped with a documented keyword mapping. Categories with fewer than 25 cards were combined into one suppressed row.
| Occasion group | Cards | Share |
|---|---|---|
| Other or unspecified | 704 | 32% |
| Farewell and retirement | 698 | 31.7% |
| Birthday | 525 | 23.9% |
| Thank-you | 119 | 5.4% |
| Get well | 77 | 3.5% |
| Sympathy | 45 | 2% |
| Suppressed small cohorts | 33 | 1.5% |
Designed for citation without exposing a single card
The query logic is reproducible in the Sharewell codebase. This public page contains aggregate outputs only.
Population and window
All 2,201 cards created from 1 January through 30 June 2026 with no deletion timestamp. The fixed completed window avoids partial-month reporting.
Valid contributions
Messages marked deleted were excluded. A message also had to be posted on or after its card’s creation and before 1 July 2026. 0 records failed the timestamp rule.
Privacy threshold
No raw messages, images, card titles, recipient names, organizer details, emails, IP addresses, or IDs were extracted. Occasion cohorts below 25 cards were suppressed and combined.
Time to first contribution
Elapsed hours from card creation to the earliest valid message. This measure uses 1,593 active cards and excludes cards with no contribution.
Photo rate
A message counted as photo-bearing when either its standard or high-resolution image field was present. The analysis inspected field presence only, never image content.
Reminder impact
Not estimated. No randomized or otherwise causal comparison was available in the period. Sharewell will not label an observational difference as a reminder effect.
What these numbers do—and do not—represent
Selection bias
This is a descriptive census of eligible Sharewell records, not a representative survey of every group card created online. People who choose Sharewell may differ from other card makers.
Free-text occasions
Occasion values can be missing, custom, or written in English, French, and Spanish. The “Other or unspecified” group is therefore large and should not be interpreted as one occasion.
Public-counter difference
Before 1 July, the operational counters contained 10,607 stored cards and 118,112 stored messages. Index totals are lower because they use a six-month window and deletion/validity rules.
Snapshot generated 24 July 2026. There were 3 eligible cards with a missing occasion value. Three occasion cohorts totaling 33 cards were below the publication threshold.
A short, citation-ready summary
Sharewell Group Card Index 2026: In a privacy-safe analysis of 2,201 non-deleted group cards created from January through June 2026, the median active card received 12 messages. The median first contribution arrived within 0.5 hour, and 15.7% of 23,108 valid messages included a photo. Sharewell published aggregate results only and suppressed occasion cohorts smaller than 25 cards.
