How to Send Email using MATLAB

To send an email from MATLAB®, use the sendmail function. You can also attach files to an email, which lets you mail files directly from MATLAB. To use sendmail, set up your email address and your SMTP server information with the setpref function.

The setpref function defines two mail-related preferences:

  • Email address: This preference sets your email address that will appear on the message.

  • SMTP server: This preference sets your outgoing SMTP server address, which can be almost any email server that supports the Post Office Protocol (POP) or the Internet Message Access Protocol (IMAP).


Once you have properly configured MATLAB, you can use the sendmail function. The sendmail function requires at least two arguments: the recipient's email address and the email subject.

sendmail('','Hello From MATLAB!');

You can supply multiple email addresses using a cell array of character vectors.

sendmail({'',''},'Hello From MATLAB!');

You can specify a message body.

sendmail('','Hello From MATLAB!','Thanks for using sendmail.');

You can attach files to an email.

sendmail('','Hello from MATLAB!','Thanks for using sendmail.','C:\yourFileSystem\message.txt');

Note: You cannot attach a file without including a message. However, the message can be empty.

You can attach multiple files to an email.

sendmail('','Hello from MATLAB!','Thanks for using sendmail.',{'C:\yourFileSystem\message.txt','C:\yourFileSystem\message2.txt'});
