How is engagement evolving?
Month-over-month engagement across every channel, December 2025 to October 2026. December and October are part-months. Slack interaction is not an open rate and is not comparable to email.
Click rates use click-eligible communications only. December 2025 (from 22 Dec) and October 2026 are part-months and are left out of every average.

Most slots rest on one or two communications, so these comparisons are directional. Work email rates; automated onboarding excluded.
Work email, 38 communications over 38 send occasions with at least 10 deliveries. Open rate counts a click as an open. CTR here is clicks divided by opens, which this hub calls click-to-open. Automated new-hire onboarding sends are excluded (3 email communications, 33 deliveries); they fire per person from the start date, so their hour is not a send-time choice. The 4 email communications sent before open tracking began are excluded.

Turning communication data into actions
Every insight below is computed from ChangeEngine's own delivery, open, click and reaction records — no illustrative data.
Best day & time to send
DirectionalMonday or Thursday · 12:00–14:59 ET
Work email sent between 12:00 and 14:59 ET averaged a 73.1% open rate across 10 communications (4,782 deliveries), against 67.7% for 15:00–17:59 (22 communications). Monday (76.6%) and Thursday (76.3%) led that window, each on two to four communications. Nothing was sent before 09:00 or after 18:00 ET, or at weekends, so those times are untested.

Highest-performing communications
Why Remote Work Works leads at 79.7% email open rate across 345 deliveries.
Lowest-performing communications
CB Intro Session Recap sits lowest at 58.1% email open rate across 613 deliveries.
Click-to-open
Of people who opened a work email with a link, 8.4% clicked. Over all deliveries that is 5.9%.
Message load and opens
The number of messages someone received in the prior seven days shows no meaningful link to whether they opened the next email (r = -0.05).
Who are we reaching?
998 employees — 72.6% of the workforce — received at least one communication in the window, across 10 work locations.

What are we talking about?
Where communication effort is concentrated across Babylist, measured by share of the 18,752 deliveries in the current selection.
Tile size reflects share of deliveries. Topic is derived from the program title prefix. Select a tile to drill down.
Benefits
Are we communicating at the right frequency?
Communication load across departments and days, plus what the data says about saturation at Babylist.
No employee exceeded 5 communications in any rolling 7-day window, and the median is 2. Engagement does not fall measurably as load rises (Pearson correlation, concurrent 7-day load vs email opened (0/1): r = -0.0458, n = 16,380). The effect size is negligible, so saturation must not be presented as a finding in this window.
Does engagement fall as load rises?
Email open rate by the recipient's concurrent 7-day communication load.
r = -0.046: load in the prior seven days explains almost none of the variation in whether an email is opened.
How are our programs performing?
9 programs in the current selection, benchmarked against the 69.6% window-wide email open rate.

Which channels work best?
Email reports opens and clicks. Slack reports interaction signals — deliveries, clicks and reactions — never an open rate.
Email (work)
Slack DM
No open equivalent exists on Slack. Not comparable to an email open rate, and not comparable to the other chat platform: what is tracked and how the client runs them differ.
Slack Channel
Why click-to-open, not click rate
a communication with at least one recorded click (proxy for containing a link) — messages with no link cannot be clicked, so they are excluded from click denominators.
a communication with at least one recorded click (proxy for containing a link)
Email senders
- hr@babylist.com90.3% 46 send occasions
- James.Shelby@babylist.com71.7% 30 send occasions
Email open rate, manual sends only: the mean of each send occasion's rate, adjusted toward the 82.9% average for senders with few occasions.
May 2026
Open rate, click-through and Slack interaction come straight from the latest delivery feed. Communication load is calculated on distinct audiences reached, not raw send count — four communications to four different divisions is not overcommunication.
May 2026 is the highest-volume full month in the window. Each card is the first send of a communication in that month. Automated onboarding communications are drawn once, on their first send in the month, and marked with the onboarding event.
What should we do next?
Analytics → Insight → Recommendation → Action. Every recommendation below is traceable to a measured figure in this Hub.
Work email click rate of 5.9% counts every unopened email against the content.
Best-performing email slots: Monday 12:00 (79.2%); Friday 11:00 (77.9%); Tuesday 17:00 (76.9%).
CB Intro Session Recap and MDLive LIVE sit well below the 69.6% email open rate.
