Matlab r2015a send email code#
In this case, the code automatically infers HTML formatting based on whether the first character in the message body is a ‘<‘ character. SendEmail ( 'email subject', 'HTML-formatted message' ) % HTML-formatted 'email subject', 'regular text message') % will send a regular text 'email subject', 'HTML-formatted message') % HTML-formatted message SendEmail ( 'email subject', 'regular text message' ) % will send a regular text message We would then call the wrapper function as follows: % character vector specifying a single address, or a cell array of character vector % SENDMAIL(TO,SUBJECT,MESSAGE,ATTACHMENTS) sends an e-mail. % The rest of this file is copied from %matlabroot%/toolbox/matlab/iofun/sendmail.m (with the modifications mentioned above):įunction sendmail(to,subject,theMessage,attachments) %SENDEMAIL Send e-mail wrapper (with HTML formatting) įunction sendEmail(to,subject,theMessage,attachments) TO is either a % character vector specifying a single address, or a cell array of character vector. The basic idea for the second alternative, the sendEmail.m wrapper, is something like this (the top highlighted lines are the additions made to the original sendmail.m, with everything placed in sendEmail.m on the Matlab path):įunction sendEmail (to,subject,theMessage,attachments ) %SENDEMAIL Send e-mail wrapper (with HTML formatting) sendmail (to,subject,theMessage,attachments ) % The rest of this file is copied from %matlabroot%/toolbox/matlab/iofun/sendmail.m (with the modifications mentioned above): function sendmail (to,subject,theMessage,attachments ) %SENDMAIL Send e-mail. The downside is that our wrapper function will be stuck with the version of sendmail.m that we copied into it, and we’d lose any possible improvements that Mathworks may implement in future Matlab releases.

This has the benefit of working on multiple Matlab releases, and being copied along with the rest of our m-files when we install our Matlab program on a different computer. Copying %matlabroot%/toolbox/matlab/iofun/sendmail.m into a dedicated wrapper function (e.g., sendEmail.m) that has a similar function signature and exists on the Matlab path.In general, I discourage changing Matlab’s internal files because it is simply not very maintainable. You will also need to redo the fix whenever you install Matlab, either installation on a different machine, or installing a new Matlab release. You will need administrator rights to edit this file. Making the changes directly in %matlabroot%/toolbox/matlab/iofun/sendmail.m.It’s useful to note two alternatives for making these fixes: MaxLineLength = inf % or some other large numeric value Deployment MaxLineLength = inf % or some other large numeric value This can be done by changing the following (line #291 in the original sendmail.m file of R2017a): In addition, I also found it useful to remove the hard-coded 75-character line-wrapping in text messages. IsHtml = ~isempty(body) & body(1) = '<' % msg starting with '<' indicates HTMLĬharset = setContent (body, charset ) elseif ~isempty (charset ) messageBodyPart. setContent (body, charset ) elseif ~isempty (charset ) msg. IsHtml = ~isempty (body ) & body ( 1 ) = '<' % msg starting with '<' indicates HTML if isHtml if isempty (charset ) charset = 'text/html charset=utf-8' else charset = end end if numel (attachments ) = 0 & ~isHtml if isHtml msg. % Construct the body of the message and attachments. To implement these features, change the following (lines #119-130 in the original sendmail.m file of R2017a, changed lines highlighted): We need to specify 'text/html' as part of the message’s encoding.HTML formatting required calling the message-object’s setContent() method, rather than setText().Only two small changes are needed in sendmail.m to support HTML formatting:

However, Matlab’s sendmail function only uses part of the functionality exposed by these classes (admittedly, the most important parts that deal with the basic mail-sending mechanism), and does not expose external hooks or input args that would enable the user to take full advantage of the more advanced features, HTML formatting included. The Java classes are extremely powerful and so there is no wonder that Mathworks chose to use them rather than reinventing the wheel. Today I will show how we can send such HTML emails from Matlab.Ī quick recap: Matlab’s sendmail function uses Java (specifically, the standard javax.mail package) to prepare and send emails. Text-only emails are naturally very bland and all mail clients in the past 2 decades support HTML-formatted emails. Unfortunately, Matlab only sends text emails by default and provides no documented way to send HTML-formatted emails. A few months ago I wrote about various tricks for sending email/text messages from Matlab.
