Tool for sending bulk mail using Exchange / Office365

You need to specify two things: a text template for the mail, and a list of recipients as a TSV file. For each entry in the recipient list, an email will be sent.

The tool will prompt for your credentials every time.

The mailing list should be a TSV file. The first line should be a header providing names for each of the columns; each header name should be unique. Each subsequent line should have the same number of fields as the header line. These values will be substituted into the template to produce a well formed message, then sent.

The template file should consist of two parts. The first part is a series of headers, one per line, ending with a blank line. The remainder of the file is the HTML body of the message.

The following headers may currently be used (note: header names are not case sensitive):

subject

The subject of the mail. Should occur once. The last occurrence will overwrite any prior occurrences.

to

One recipient of the mail. This field can occur many times. Each occurrence should contain exactly one recipient email.

cc

Same as above, but for CC instead of To

bcc

Same as above, but for BCC instead of To

attach

Filename to be attached to the email

Providing any other header will cause an error.

Inside the template, variables may be used anywhere. They will be replaced by the value provided in the mailing list before a message is created in sent. Variable names surrounded by two square brackets will be substituted by their value. Note that variable names are case sensitive.

No error checking on variables is currentlly performed. If you mistype the name of a variable, it will not be replaced by anything, and no error will occur. Sorry.

Consider the following example files:

Subject: test message to [[FirstName]] [[LastName]]
To: [[Email]]
Cc: cc_person_1@bar.bz
Cc: cc_person_2@bar.bz
Attach: file_[[Id]].txt

<p>Dear [[FirstName]],<p>

<p>Please see the attached file for more information.</p>

<p>This message was sent to [[Email]]</p>

This will result in two emails being sent. The first email will have attached the file_19.txt and look like this:

Subject: test message to Jane Doe
To: foo@bar.baz
Cc: cc_person_1@bar.bz
Cc: cc_person_2@bar.bz
Attach: file_19.txt

<p>Dear Jane,<p>

<p>Please see the attached file for more information.</p>

<p>This message was sent to foo@bar.baz</p>

The second will have the attachment file_22.txt and have the corresponding replacements.
