ProTip: use Boomerang for GMail for scheduling emails.

Installation

You need to generate your own Google Gmail API Credentials – there’s a great tutorial avilable at Google Developers.

Download binaries or build from source. Keep the client_secret.json in the same directory as binary. On the first run enmasse will ask you to open a browser and perform authentication.

Example usage

enmasse -template=template.tmpl -data=addresses.json

addresses.json:

[{
    "first_name": "Alistair",
    "email": "alistair.hennessey@gmail.com",
    "title": "PhD"
}, {
	"first_name": "Klaus",
    "email": "klaus.daimler@gmail.com",
    "title": "Research Assistant",
    "label": "Team Zissou"
}, {
    "first_name": "Ned",
    "email": "ned.plimpton@gmail.com",
    "location": "Port-au-Patois",
    "label": "Team Zissou"
}]

template.txt:

Hey {{ .first_name }},

{{ if .title }}
I guess I should be pretty impressed that you’ve achieved the rank of {{ .title }}...
{{ end }}

Now if you'll excuse me, I'm going to go on an overnight drunk,
and in 10 days I'm going to set out to find the shark that ate my friend
and destroy it. Anyone who wants to join me is more than welcome.

Best regards,

Steve

P.S. I’ve attached your party invitation.

{{ if .location }}
P.S. 2 {{ .location}} is pretty nice this time of the year, right?
{{ end }}

Flags

-template=FILE    Template file
-data=FILE        JSON data file

Scheduling messages

A built-in scheduling function would be nice, but a) I feel it’s out of scope, b) it would require a lot of work and most likely require a backend of some sort, and c) Boomerang for GMail seems to work like a charm.
