You can send the mails with custom subject and content in which you address people specially in cases like congratulating, events, special day celebrations. This is something that especially the HR needs.
This way, you don’t deal with sending mails one by one. You only need to indicate the mail list and details.
Create a Table
Open en Excel in OneDrive. Add a Table from the Insert tab.
Write Mail, Name Surname and mail details into the columns of this table like below.
Each row of this table will be sent as separate e-mails by the flow.
Flow Process with Power Automate
Start a new blank flow.
After the data in the table is filled, flow will be run by being triggered individually. For this reason, start the flow with Manually trigger a flow.
In the next step, add Excel for Business (List rows present in a table) to be able to add the data in the Excel table. Add the table you’ve just created into this item.
In the next step, add Outlook (Send an e-mail).
