-## Accounts that never logged-in
+## 🔐 Accounts that never logged-in
 
 By default, accounts that have never logged in at all, will be spared from removal. To also take them into consideration, set the config flag accordingly:
 
-`occ config:app:set user_retention keep_users_without_login --value=no`
+```shell
+occ config:app:set user_retention keep_users_without_login --value='no'
+```
 
 In this case the number of days will start counting from the day on which the account has been seen for the first time by the app (first run of the background job after the account was created).
 
 ### Example
 
 Retention set to 30 days:
 
-Account created | Account logged in | `keep_users_without_login` | Cleaned up after
----|---|---|---
-7th June | 14th June | yes/default | 14th July
-7th June | 14th June | no | 14th July
-7th June | - | yes/default | -
-7th June | - | no | 7th July
+| Account created | Account logged in | `keep_users_without_login` | Cleaned up after |
+|-----------------|-------------------|----------------------------|------------------|
+| 7th June        | 14th June         | yes/default                | 14th July        |
+| 7th June        | 14th June         | no                         | 14th July        |
+| 7th June        | -                 | yes/default                | -                |
+| 7th June        | -                 | no                         | 7th July         |
+
+## 📬 Reminders
+
+It is also possible to send an email reminder to accounts (when an email is configured).
+To send a reminder **14 days after** the last activity:
+
+```shell
+occ config:app:set user_retention reminder_days --value='14'
+```
+
+You can also provide multiple reminder days as a comma separated list:
+```shell
+occ config:app:set user_retention reminder_days --value='14,21,28'
+```
+
+*Note:* There is no validation of the reminder days against the retention days.
