How to Send Email from R

how do you send email from R

I just tried it out, and it worked for me.

My only differences were I used <> for the from and to:

from = "<email1@dal.ca>"
to = "<email2@gmail.com>"

and my mail control was different, I used

control=list(smtpServer="ASPMX.L.GOOGLE.COM"))

Sending emails in R without outlook app in the system

Solved the problem, using mailR package and it works well.

library(mailR)
send.mail(from = "email@company.com",
          to = "email@company.com",
          subject = subjectToSend ,
          body = bodyToSend,
          html = TRUE,
          smtp = list(host.name = "smtp.company.com", port = 25), 
          send = TRUE)

Sending email without Java in R

The following works.

library(sendmailR)

msg = mime_part(bodyToSend)
msg[["headers"]][["Content-Type"]] = "text/html"

sendmail(mailFrom,mailTo,subject, msg, control=list(smtpServer= "smtpserver"))

Sending email in R via outlook

You can use RDCOMClient package to access to COM objects from within R. You can easily access the Application Object (Outlook) and configure it. Here a simple example of sending an email:

library(RDCOMClient)
## init com api
OutApp <- COMCreate("Outlook.Application")
## create an email 
outMail = OutApp$CreateItem(0)
## configure  email parameter 
outMail[["To"]] = "dest@dest.com"
outMail[["subject"]] = "some subject"
outMail[["body"]] = "some body"
## send it                     
outMail$Send()

Of course, this assumes that you have already install outlook and configure it to send/receive your emails. Adding attachment is quite simple also:

outMail[["Attachments"]]$Add(path_to_attch_file)

sending on behalf of secondary mailbox:

outMail[["SentOnBehalfOfName"]] = "yoursecondary@mail.com"

Send authenticated mails via Outlook through R using mailR package

This took me a while to figure out. Try this:

send.mail(from = "username@custom.org",
          to = c("recipient1@custom.org", "recipient2@custom.org"),
          subject = "Title",
          body = "Hello from R.",
          authenticate = TRUE,
          smtp = list(host.name = "smtp.office365.com",
                  port = 587,
                  user.name = "username@custom.org",
                  passwd = "Pa55w0rd",
                  tls = TRUE))

It is a common misconception that the port is 25 or 447. I believe port 25 can only be used whenauthenticate = FALSE.

Many sources claim that the correct server is smtp-mail.outlook.com. Perhaps you could try this in the event that the code does not work. Moreover, do not use ssl = TRUE. It has to be tls = TRUE.
