Thank you very much for watching.

The scenario is like this: I have a List A with a column of people's names, and I need to send an email to different person in each row, and each person's email is stored in List B. How do I implement this?

Since I am just using powerautomate, please understand if there is something I don't understand, thank you for your help!

Hi @XiaohuLiu

Is there a relationship between the lists right now?

If not, you can create a new column in the list A of type lookup and select the lookup list as list B.

In your flow, you can do get items to get the items from list A and then in an apply to each loop, you can add the Get Item action for the list B and for ID pass the value from the lookup field of List A. You can add an email action then and have data from both the lists included in the email.

Hope this Helps!

Hi @XiaohuLiu

You have to try this approach

1. Use Get items to get all items from List A

2. Use apply to each loop through all items from output of Get Items action.

3. Use get items for List B with filter query like below
name eq (dynamic content of name from List A)
Like below

Instead of name , here it is customer

Next we will validate whether the values are present or not, if yes then send an email like below

Here values will be from output of Get Items for List B 🙂

Hope it helps 🙂

@Nived_Nambiar Thank you very much for your reply, but I have some problems with the running process.
I understand according to your idea like this, first get all items in LIST A, then use aplly to each, get items in LIST B, the filter condition is equal columns in both LIST. Then send an email with the obtained Email.
I do not quite understand that

1. why add a conditional judgment, using length (...)
2. how to use the column name in Get Items 2? I input it directly and it will show that the column does not exist, and there is only the column name in Get Items 1 in Dynamic content.

Thank you very much for your help.

Hi @XiaohuLiu

Please find answers to your questions below

1. why add a conditional judgment, using length (...)

It is an extra step to validate whether the value we are trying to serach in List1 with value from List1 exists or not. This is done by using length function applied on values dynamic content of Get items 2 action.

2. how to use the column name in Get Items 2? I input it directly and it will show that the column does not exist, and there is only the column name in Get Items 1 in Dynamic content.

In dynamic content you will find the Column Name (which itself is the value) under Get Items action

Let me know if you have additional questions 🙂

Hi @XiaohuLiu,

I understand that you may be experiencing some difficulty when trying to add a filter in the 'Get Items' action. Fortunately, with the help of experimental features in Power Automate Studio, you can simplify the process of adding filter conditions.

Once you have added the filter, you can toggle off the experimental feature to return to the standard version of the Studio.

If my suggestion has been helpful, please consider giving it a Thumbs Up!

Best Regards,
Venkadesh Sundaramurthy

@Nived_Nambiar Hi,
If I don't add "[]", the system will prompt me: Column "name" does not exist
