When person is assigned, notify them only once (not again when others are added)

Hi everyone,

I’m trying to refine an automation around a People column. Right now, my automation is:

  • When a person is assigned, notify person.

The issue: if I assign one person, they get notified (as expected). But if I later assign another person (or multiple more people), the original assignee gets notified again—sometimes ending up with 3–4 duplicate notifications.

What I’d like to achieve is:

  • Only newly added assignees receive the notification.

  • People who were already assigned should not get duplicate notifications if others are added afterward.

Is there a way to edit or structure an automation so it only triggers for new additions to a People column rather than re-notifying everyone each time?

Thanks in advance for any tips or workarounds!

Can you share which automation formula you’re using currently?

Hi Lindsey,

The default “When a person is assigned, notify them” automation notifies everyone in the People column, so existing assignees get duplicates when new people are added.

A workaround is to use a helper column (like a checkbox or status called “Notified”):

Trigger the notification only if “Notified” is unchecked.

After notifying, mark “Notified” for that person.

This way, only newly added assignees get notified. You could also use tools like Integromat/Make or Zapier for more precise control.

Here is a screenshot of the automation formula:

And is people in this situation a person or a team?

There could be anywhere from 3-5 people assigned to a single item in Monday.com, so more a team than a single person. We don’t want to add multiple columns for each role, as each item varies on the level of involvement needed, and want to keep our board concise as we have many other columns

Hey Lindsey, I’ve got this automation as part of an app:

When person is assigned notify newly-assigned people

After a person is added, it only notifies whomever was added. It will only notify again if that person is removed and then added again.

Hey Lindsey, I ran into the same issue before. One workaround I found is to create a secondary “helper” column (like a status or checkbox) that marks if someone has already been notified. Then you can set your automation to only notify when that column is unchecked. It’s a bit of a hack, but it prevents duplicate notifications.
