A. Using Command

John (john2) <John@example.org>; Peter James (pjames) <James@example.org>;

You can get user email by ge-explore with <owner>/<repo>. The email addresses are responded in a formatted string. You can copy contact list to any email service you have, then send your email with those contact address.

(If you encounter the situation of limitation from GitHub server during running the command, please add --client_id <your_github_auth_id> --client_secret <your_github_auth_secret> with the command above. Get Client ID and Client Secret by OAuth applications.)

B. Using Python Script

from github_email_explorer import github_email

ges = github_email.collect_email_info('yuecen', 'github-email-explorer', ['star', 'watch'])

for ge in ges:
    print ge.g_id, "->", ge.name, ",", ge.email

# With Authentication
# github_api_auth = ('<your_client_id>', '<your_client_secret>')
# ges = github_email.collect_email_info('yuecen', 'github-email-explorer', ['star', 'watch'],
#                                        github_api_auth=github_api_auth)

How to Send a Email to GitHub Users from a Particular Repository?

1. Write Email Content with Template Format

The Jinja2 is used to render email content in github-email-explorer, basic expressions make email content more flexible for personal information.

Here is an example to use following syntax, the file saved to examples/marketing_email.txt

subject: Thanks for using {{repository}}
from: test@example.com
user:
repository: yuecen/github-email-explorer
repository_owner: yuecen
repository_name: github-email-explorer
site: GitHub

<p>Hi {{ user.name }} ({{ user.g_id }}),</p>
<p>Thank you for trying {{ repository_owner }}/{{ repository_name }}!</p>

<p>...</p>

<p>I look forward to seeing you on GitHub :)</p>
<p>yuecen</p>

site is not a essential field, it will be in SendGrid custom_args field for log

You can use syntax {{ ... }} to substitute metadata field in runtime stage for personal information.

2. Send Email

In order to send email to many users flexibly, we combine the email list from result of ge-explore and SendGrid to approach it.

ge-sendgrid --api_key <your_sendgrid_api_key> 
            --template_path <github-email-explorer_folder_path>/examples/marketing_email.txt

The following image is an real example of email format for ge-sendgrid command.
