Concatenation of String

Is the user in Appian?

Yes , he is in Appian.

I just created an expression rule that has two inputs user and domain. In the rule the code is ri!user&ri!domain and the value comes back correctly. Another option would be to look up the user in the Appian user table and get the email address. Something like user(pv!abc, email)

@rohandhondilak Would you please be let us know at a high level on what you have tried? And when you mean none of them worked, what is it that you are experiencing - an error or a successfully completed node without sending any email?

I believe you would have already done concatenation as it's straight forward. Did you apply the following conversion over the concatenated string prior to including the recipient details in the to/cc of Send email node? I believe it might be worth giving a try.
fn!toemailrecipient(fn!toemailaddress(fn!concat(pv!abc,domain.com)))

There could be some more issues here but I am looking at the validity of the recipients in the first place.

Hi rohandhondilalk,

If you have user with valid email id configured while creating or updating that your, then you can directly use that user as recreant for sending email. because if you give user as input then appian will automatically take the email provided for that user.

If in case you want to use email id like pv!abc with domain name, in that case you can concatenate them like pv!abc & "domain.com" and you need to use toemailaddress() or toemailrecipient() to convert that text value into email type.

It will be like toemailaddress(pv!abc & "domain.com") which will Email Address type as output.

@rajasekharp,

We have tried the same and its not working with us.

@rohandhondilak Did you try the combination of both, that is, toemailrecipient(toemailaddress()) or only one of them?

@ sikhivahans,
Thanks . The recipients are valid and we had tried the fn! which you had mentioned.

@sikhivahans,

As of now we tried individually, we will try both and update you. thanks :)

No worries, ideally both are needed afaik but not one of them. Because toemailaddress() converts the data type of source(which is concatenated string in your case) to Email Address type and toemailrecipient() converts this Email Address type to Email Recipient type which then becomes valid to be used in to/cc of the Send Email node.
