Send a mail to multiple people

Create an expression rule where you pass in the location ID of your choice, and possibly any other identifying information, and as an output, returns the email addresses for the desired target audience.  This would just be an array of text where each member is an email address, and you probably need to wrap it in the toEmailAddress() function for it to play nice with the Send Email node (i've never been sure why).  Then you just set the "To:" field in the Send Email node with that expression rule.

Hi Mike i have used your logic but am getting below Error

Hi Akshayg,
What type of value are you passing to toemailaddress()?
Did you try that expression separately with the same input? Si it returning valid email addresses?
try that expression separately and make sure it is returning valid email addresses.

1. i was recommending that you create an expression rule to handle the logic, which is not really what you did here...
2. what you did here should work provided the value of "pv!sendTo" is a valid email address.  Can you verify what its value is in the instance where you got the error?  What type is it set as?

I had used like this but it was throwing error "no valid recipients resolved"...so  was trying different way to solve ... Can you tell what change should i make..

Hi Karthik ... that rule is working fine and returning value.. But for some location Say B don't have Email Address for M3 and M4 ..for that am using XOR gate

I'm unable to tell what the issue might be since you haven't shared what value(s) your expressions are producing.  In the previous screenshot you would need to show us what the in-process value of "pv!sendTo" was.  In the newer screenshot, what is the output of the 'AER_getEmail()` expression rule when you provide realistic test data like what you'd get in a running process?  And is there a reason you don't put the "toEmailAddress()" rule inside the expression rule itself?

Well the Expression AER_getEmail() based on location iD am fetching the mail Address . Do refer this screen  shot and have used toemailAddress inside rule still am getting same error as above

But I'm asking you to confirm what output you get when you run that rule in the Expression Rule Editor.  Just as before I have no way of confirming whether the value you're passing into the TO: field would be valid without seeing an actual example of the resulting value you're passing into it.

i wish i could share that information...

You should be prepared to show test data or at least redacted data if you're hoping to find help here with issues like this, since we can't just guess as to what values you're trying to pass into the email node.

Even if you can't share a screenshot of test data, sharing the expression for rule!AER_getEmail() would be helpful for us to help you troubleshoot.

rule!AER_getEmail()-- am trying to fetch email based on locationId

From your screenshot I still can't really judge whether we'd expect this expression rule to give valid output (i.e. a single valid email address or an array of string where each entry is a valid email address).

Anyway thanks mike will check with internal team then, if someone can help me out

Yeah I would say this needs to be run by someone with authorization to see the output of that rule, because from the error message you posted earlier it looks as if (at least in the instance where you go the error, if not all instances) no valid email addresses are being output.
