Mailing Automation Scripts

Automates the mailing process for KOSS during various events like KWoC and selections.

Warning Always do a test run before using the scripts, there are many things which might go wrong and we can't afford sending broken/incorrect mails to the reciepients.

How to use

0. For the first time, you need to generate token for api.

1. Either use already available templates or create a new template with the conventions mentioned in about templates.

2. Make sure the the column names for name and email entries are one of those mentioned in variable_mappings.py.

3. Make sure the files are stored in correct directory:

   • Templates files must be stored in ./templates/.
   • CSV files must be stored in ./csv/,

   Hence no need to mention them again while specifying the location, just speciy the location after these default directories.

4. Use the script according to your needs, bcc.py or one-to-one.py. Both follow same method of execution

   python3 script.py <template> <csv_file> (OPTIONAL)<variables with same value for all mails>

Executing the scripts

Here are one example for each case supported:

python3 one-to-one.py selections/onboarding onboarding.csv number_of_applicants="250+"
python3 one-to-one.py selections/task day1.csv deadline="Monday, 9 June 2023"
python3 bcc.py selections/rejection rejected.csv
python3 bcc.py selections/round1-interview-slot r1d1.csv slot_time="Tuesday, 3 June 2023, 10:00 PM - 11:00 PM" lobby_link="https://meet.google.com/xxx-xxxx-xxx"

Generating token for GMail enabled googleapi

1. Follow the steps at Gmail API - Python Quickstart guide to get credentials.json.

   Note credentials.json is permanent until you delete it in your google clound console.
   And make sure to add [email protected] as a test user in case you made the app internal.

2. Follow the steps below to generate token.json:

   • Download gentokenjson.py in the same folder containing credentials.json

   • Import the required module

     pip install google-auth-oauthlib

   • Execute gentokenjson.py with send argument

     python3 gentokenjson.py send

   • Browser window will open and ask you to select the account, choose the one receiving OTP for login

   • Allow permission on that email to use just enabled GMAIL API

     • Click on Continue instead of Back To Safety
     • Then press Continue again

   • token.json will be generated in same folder as that of credentials.json

   Warning token.json expires after sometime. So make sure to check that in your projects and keep refreshing it.
