RE: Send an e-mail at x5 roll-up column
Hi Serge Pilaet,
First of all, a rollup field cannot be used to trigger a flow or workflow.
So you need to create a new field and set a business rule for it to pass the value of the rollup field to it.
For example, there is a rollup field to count the number of the contacts named as "Count of contacts"/ "new_countofcontacts".
The new field is named as "Count of contacts1"/ "new_countofcontacts1", whose value equals to the value of the rollup field.
Then create a flow triggered when the new field is modified.
Initialize it as a variable.
Add a condition to send an email if this variable is divisible by 5. The variable can be inserted into the content of the email directly.
Then when the count of the contacts hits 5, the email address of the account will receive a notification email.
