Bulk Emailer

When you have to bulk email a bunch of people(any reason?), this script can help you do that. You can email different emails to different people via this script, and the rust template helps with that.

The primary motive of this script is -> Things are not looking good at the $ORG and hence I am job hunting hence the need to send multiple HRs my resume and the email asking for the job opportunity/referral.

So, the idea is->

• You create a user which is going to be used to send the emails.
  • That user is saved in the file database, using sled for this. Much like boltdb which is an embedded K/V store for go and is much more familiar for it's wide usage in a lot of big open source projects including some from CNCF.
• You write the email content along with the subject in a .hbs file. It should be a templatised content, example attached in the repository itself at ./email.hbs. Use chatgpt or anything else to create the content. That is not in the scope of this CLI, and this won't be turning into a TUI either to give a scratchpad to write emails(atleast as of now, that is the focus).
  • The subject has to be the first line and can contain template parameters.
  • The rest of the lines are body, can be long and can contain template parameters as well.
• You create another csv file with the list of emails and the template parameters. Example attached in the repository itself at tos.csv which can simply be gotten by running cat emails.csv| awk -F ',' '{print $1 " <" $3 ">," "\"fname="$1"\""}' | sed 1d > tos.csv.
  • The first line is the header, and the first column is the email address.
  • The second column contains all the template params in the format key=value separated by ,.

How to use it->

The repository doesn't ship pre built binaries... yet. So, you'll have to build it yourself. To build it, you will need to have rustc or cargo installed and clone this repository.

Once you have the components required installed, the repository also ships with the justfile as well which can be run by the just runner. The available just commands are->

Use just b to build the binary, use just -l to explore all the commands.

Once you have the binary compiled, it will reside in ./target/release with the name of the mail-rs. Feel free to play with it, help is available for all the commands and sub commands.

Steps

User Help->

• Create a user.

./target/release/mail-rs user add -f vishal -l sharma -d vishal -e vishal.sharma09890@gmail.com --provider gmail --password abcd

• Send mail.

./target/release/mail-rs mail -c email.hbs -t tos.csv -d

-d is for dry run and not actually send.

-s is to send the email actually.

-ds to dry run and send the email.
