Sending Email from Org Mode
Every so often, I need to generate a bunch of form emails.
Often, I’m sending the same email to multiple groups of people and I want use variables, such as
$first_name, in the text.
While I’m sure there a number of online services which could achieve this for me, I really don’t need to set up a fancy campaign or use tracking.
Plus, I’m wary of submitting others’ emails to a third party.
Of course, I’ve used Emacs to do this, using org mode and AppleScript.
To approach this task I start with a single org file.
Getting AppleScript executing from an org block is trickier than I would like.
Instead, I write the script whole cloth in my org file and tangle it out to a separate
I store the data in my file as a table.
I then use a bash block, which takes the data through
:var, to loop over running the script.
AppleScript for Email
I’ve never formally learned AppleScript, but some searching on StackOverFlow and trial-and-error can get you pretty far.
Mac OS X has a built in editor found in
Once you’ve opened the editor, you can browse the dictionary with
File > Open Dictionary....
This dictionary lists all the classes and commands for different applications.
The AppleScript language itself looks like natural language and is relatively easy to understand… especially once someone else has properly constructed the program.
For my email-sender script, I store the AppleScript source is as a block.
This block is tangled (
C-c C-v C-t) to a
The first half of this script sets some variables, including the body of the email message.
The second half creates the message and sets a “to” recipient (could also set a “cc” recipient).
Note that I’ve commented out the
send command and set the message property
This means that the draft emails appear in the Mail GUI, but do not get automatically sent.
This allows me to do trial runs before spamming my recipients.
Filling the Variables
Once I have the script and email body written, I know what variables I’ll need to fill in. The next step is to put all the data into a named org table. I usually do this data formatting by hand since I’m bringing together data items from many different sources.
Since I tangle the email sending AppleScript program, I need to run it from the command line.
I call the script once for each row in the data table using a bash loop and variable arrays.
Then, I use
C-c C-c to run the bash loop and generate the emails.
Note that I do not calculate the total number of data items / rows.
That would take way too much bash magic for this simple example.
Also, if you want to test the variables with an
echo statement, use
:results output as an argument to the org block.
I usually choose to manually hit send on each individual email once I’m satisfied with the script.
I keep all of these org commands in a single
notes.org file so that I can remember how to recreate the emails (usually a year later when it’s time to send them again).
For example, this notes.org file sends introduction emails for a mentoring program I organized with Women in HPC.
