Sending emails with powershell

Dylan October 26, 2014

When automating tasks in powershell notifications are key, luckily this task is made much simpler with powershells “Send-MailMessage” cmdlet.

In a simplistic form you could use a one liner:

send-mailmessage -to "$emailTo" -from "$emailFrom" -subject "$subject" -body $message -smtpserver $smtpserver -credential $creds

1	send-mailmessage -to "$emailTo" -from "$emailFrom" -subject "$subject" -body $message -smtpserver $smtpserver -credential $creds

But if you plan on calling this often, why not build a simple function to handle all emails.

function Mailer ($SO, $ID, $Reason)
{
   $message = @" 

Warning: $ID
with SalesOrder: $SO
for reason: $Reason

Please confirm that the information is correct.
"@        

#Set Creds
$secpasswd = ConvertTo-SecureString "PASSWORD" -AsPlainText -Force
$creds = New-Object System.Management.Automation.PSCredential ("USERNAME", $secpasswd)

#Set email vars
$emailFrom = "EMAILFROM"
$subject="SUBJECT $ID with $SO"
$smtpserver="SERVER"
$emailTo="EMAILTO"
send-mailmessage -to "$emailTo" -from "$emailFrom" -subject "$subject" -body $message -smtpserver $smtpserver -credential $creds
}

function Mailer ($SO, $ID, $Reason)

{

$message = @"

Warning: $ID

with SalesOrder: $SO

for reason: $Reason

Please confirm that the information is correct.

#Set Creds

$secpasswd = ConvertTo-SecureString "PASSWORD" -AsPlainText -Force

$creds = New-Object System.Management.Automation.PSCredential ("USERNAME", $secpasswd)

#Set email vars

$emailFrom = "EMAILFROM"

$subject="SUBJECT $ID with $SO"

$smtpserver="SERVER"

$emailTo="EMAILTO"

send-mailmessage -to "$emailTo" -from "$emailFrom" -subject "$subject" -body $message -smtpserver $smtpserver -credential $creds

}

The function “Mailer” above will take in 3 parameters and use them to send an email to a pre-configured address. This script could easily be extended to allow it to mail a particular person in the event of a particular error.
