How to automate pulling email from linked board + extract timeline end date as deadline?

Hi! 👋

I’m trying to achieve two automations, and I can’t figure out how to do them using native monday.com features. Maybe someone has a workaround or solution?


✅ 1. Automatically copy email from linked board

I have two boards:

  • Subcontractors – contains a column with the subcontractor’s email address
  • Projects – connects to Subcontractors using a Connect boards column and a Mirror column for the email

I want to send emails automatically to the subcontractor from the Projects board.

The issue is: I cannot use Mirror columns in automations , and I see no option to copy the mirrored email into a regular email column that I could use in email-based automations.

❓ Is there any way to copy the email value from the mirrored column into a real Email column , either via native automation or a workaround?


✅ 2. Use the

end date

of a Timeline as a deadline

I also have a Timeline column (start – end) in the Projects board, and I want to extract the end date and use it as a deadline (e.g., in another Date column, or for reminders).

I don’t see a way to do:

“When Timeline changes → set Deadline to Timeline end date”

Is there a way to automate this? Either with built-in automation, a formula, or via an integration like Make?


Thanks in advance for any tips or workarounds! 🙏
