Send Email from R

In R, there is a package named mailR that allows you to send emails from R. In this tutorial, I will show you how to send email using gmail and MS Outlook.

R Code : Send Email from R using gmail account
subject="Test Email",
body="PFA the desired document",
smtp=list( = "",
port = 465, = "",
passwd = "xxxxxxxxx",
ssl = T),
attach.files="C:\\Users\\Deepanshu\\Downloads\\Nature of Expenses.xls")

Detailed Explanation
  1. In "from =" option, you can enter email address using which you want to send email.
  2. In "to=" option, you  need to specify email address of the recipient. Similarly, you can enter your desired subject line and body of the email.
  3. Keep and port under "smtp=" parameter as it is. Don't change anything. Enter your and password of the gmail account you want to use to send email.
  4. Under attach.files= option, you can mention path of the file you want to attach in the email.

You can add multiple recipients including the following code.
to = c("Recipient 1 <>", ""),
cc = c("CC Recipient <>"),
bcc = c("BCC Recipient <>")

R : Send email using MS Outlook

In enterprise environment, we generally send email using Microsoft (MS) Outlook. You can use RDCOMClient package to complete this task.

How to install RDCOMClient package

# For R Version (R >= 4.0.x)

# For R Version (R >= 3.5)
install.packages("RDCOMClient", repos = "")

# For R Version (R <= 3.4.4)
install.packages("RDCOMClient", repos = "")
OutApp <- COMCreate("Outlook.Application")

## create an email
outMail = OutApp$CreateItem(0)

## configure email parameter
outMail[["To"]] = ""
outMail[["subject"]] = "Test Email"
outMail[["body"]] = "Hi, How are you?"

## send it
Send HTML Email Message

The main advantage of HTML email is that it supports various formatting options. For example, it supports line break, font color etc.

Replace outMail[["body"]] = "Hi, How are you?" with the following code
bd = paste("Hi,", "<br>", "Output File has been saved on location")
outMail[["HTMLbody"]] = bd
You can also send attachments using the following syntax
