Powershell send-mailmessage - email to multiple recipients
PowershellPowershell Problem Overview
I have this powershell script to sending emails with attachments, but when I add multiple recipients, only the first one gets the message. I've read the documentation and still can't figure it out. Thank you
$recipients = "Marcel <[email protected]>, Marcelt <[email protected]>"
Get-ChildItem "C:\Decrypted\" | Where {-NOT $_.PSIsContainer} | foreach {$_.fullname} |
send-mailmessage -from "[email protected]" `
-to "$recipients" `
-subject "New files" `
-body "$teloadmin" `
-BodyAsHtml `
-priority High `
-dno onSuccess, onFailure `
-smtpServer 192.168.170.61
Powershell Solutions
Solution 1 - Powershell
$recipients = "Marcel <[email protected]>, Marcelt <[email protected]>"
is type of string
you need pass to send-mailmessage
a string[]
type (an array):
[string[]]$recipients = "Marcel <[email protected]>", "Marcelt <[email protected]>"
I think that not casting to string[] do the job for the coercing rules of powershell:
$recipients = "Marcel <[email protected]>", "Marcelt <[email protected]>"
is object[]
type but can do the same job.
Solution 2 - Powershell
Just creating a Powershell array will do the trick
$recipients = @("Marcel <[email protected]>", "Marcelt <[email protected]>")
The same approach can be used for attachments
$attachments = @("$PSScriptRoot\image003.png", "$PSScriptRoot\image004.jpg")
Solution 3 - Powershell
You must first convert the string to a string array, like this:
$recipients = "Marcel <[email protected]>,Marcelt <[email protected]>"
[string[]]$To = $recipients.Split(',')
Then use Send-MailMessage
like this:
Send-MailMessage -From "[email protected]" -To $To -subject "New files" -body "$teloadmin" -BodyAsHtml -priority High -dno onSuccess, onFailure -smtpServer 192.168.170.61
Solution 4 - Powershell
To define an array of strings it is more comfortable to use $var = @('User1 <[email protected]>', 'User2 <[email protected]>').
$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <[email protected]>', 'username2<[email protected]>')
$emailFrom = 'SomeServer <[email protected]>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom
Solution 5 - Powershell
Here is a full (Gmail) and simple solution... just use the normal ; delimiter.. best for passing in as params.
$to = "[email protected];[email protected]"
$user = "[email protected]"
$pass = "password"
$pass = ConvertTo-SecureString -String $pass -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential $user, $pass
$mailParam = @{
To = $to.Split(';')
From = "IT Alerts <[email protected]>"
Subject = "test"
Body = "test"
SmtpServer = "smtp.gmail.com"
Port = 587 #465
Credential = $cred
UseSsl = $true
}
# Send Email
Send-MailMessage @mailParam
Notes for Google Mail
- This works with Gmail if the "less secure app" option is enabled but we should avoid enabling that.
- Instead of "less secure app", enable 2-step authentication and use "Apps password"
- Use port 465 if 587 does not work.
Solution 6 - Powershell
That's right, each address needs to be quoted. If you have multiple addresses listed on the command line, the Send-MailMessage likes it if you specify both the human friendly and the email address parts.
Solution 7 - Powershell
#to send a .NET / C# powershell eMail use such a structure:
for best behaviour create a class with a method like this
using (PowerShell PowerShellInstance = PowerShell.Create())
{
PowerShellInstance.AddCommand("Send-MailMessage")
.AddParameter("SMTPServer", "smtp.xxx.com")
.AddParameter("From", "[email protected]")
.AddParameter("Subject", "xxx Notification")
.AddParameter("Body", body_msg)
.AddParameter("BodyAsHtml")
.AddParameter("To", recipients);
// invoke execution on the pipeline (ignore output) --> nothing will be displayed
PowerShellInstance.Invoke();
}
Whereby these instance is called in a function like:
public void sendEMailPowerShell(string body_msg, string[] recipients)
Never forget to use a string array for the recepients, which can be look like this:
string[] reportRecipient = {
"xxx <[email protected]>",
"xxx <[email protected]>"
};
#body_msg this message can be overgiven as parameter to the method itself, HTML coding enabled!! #recipients never forget to use a string array in case of multiple recipients, otherwise only the last address in the string will be used!!!
#calling the function can look like this:
mail reportMail = new mail(); //instantiate from class
reportMail.sendEMailPowerShell(reportMessage, reportRecipient); //msg + email addresses
##ThumbUp
Solution 8 - Powershell
No need for all the complicated castings or splits into an array. I solved this simply by changing syntax from this:
$recipients = "[email protected], [email protected]"
to this:
$recipients = "[email protected]", "[email protected]"
Solution 9 - Powershell
My full solution to send mails to more recipients using Powershell and SendGrid on an Azure VM:
# Set your API Key here
$sendGridApiKey = '......your Sendgrid API key'
# (only API permission to send mail is sufficient and safe')
$SendGridEmail = @{
# Use your verified sender address.
From = '[email protected]'
# Specify the email recipients in an array.
To = @('[email protected]','[email protected]')
Subject = 'This is a test message via SendGrid'
Body = 'This is a test message from Azure send by Powershell script on VM using SendGrid in Azure'
# DO NO CHANGE ANYTHING BELOW THIS LINE
SmtpServer = 'smtp.sendgrid.net'
Port = 587
UseSSL = $true
Credential = New-Object PSCredential 'apikey', (ConvertTo-SecureString $sendGridApiKey -AsPlainText -Force)
}
# Send the email
Send-MailMessage @SendGridEmail
Tested with Powershell 5.1 on one of my VMs in Azure.
