How I diagnose this

  • Find how often active learners come back and what they do first
  • Compare regular learners with lapsed ones
  • Check which reminders were actually opened
  • Understand the best time of day for each audience

The method behind it

The steps below are the general method. The details differ by company and product.

1

Define the habit

The action and the rhythm you want, such as a session a few times a week.

2

Time reminders well

Nudge when learners are likely to be free.

3

Celebrate progress

Recognise milestones so learners want to continue.

4

Re-engage early

Reach out as soon as the rhythm slips.

5

Keep the calendar tidy

One campaign calendar so channels do not clash.

6

Measure weekly

Weekly actives, engagement rate and session length.
