This is a simple CLI to send batch e-mails using a html-template and a list of recipients.

1. Install go

2. Clone this repository

   git clone https://github.com/rvhonorato/gomailer.git
   cd gomailer
   

3. Run or build

   go run .
   # or
   go build
   ./gomailer

1. Create a template file (e.g. template.html)

   • The template must have a {{.Name}} placeholder for the recipient's name

2. Create a recipient list file (e.g. recipients.txt)

   • In each line, the e-mail is captured as with a regular expression, all the rest is considered to be the recipients name

3. Define GMAIL_USER and GMAIL_PASSWORD system variables, by default it uses gmail as the server; if you want to use another server, you need to change it in the source code.

   • GMAIL_PASSWORD is the app password, not the account password

4. Execute;

   $ ./gomailer -h
   Usage of ./gomailer:
   -s value
         Subject of the email
   -t value
         HTML template file of the email
   -u value
         user file containing email and name as tab separated values
   
   $ ./gomailer -t template.html -u recipients.txt -s "Hello!"
   

go test -v
