}Firstly install newsletter-ses in the global environment:
npm install -g newsletter-ses
Then open the terminal and pass the JSON config to the newsletter-ses's CLI:
# simple usage
newsletter-ses '{"ses": {...}, "lists": [ ... ]}'
# redirect output to a file
newsletter-ses '{"ses": {...}, "lists": [ ... ]}' > output.logYou can also use pipe |:
# use local config
cat path/to/config.json | newsletter-ses > output.log
# use remote config
curl https://example.com/config.json | newsletter-ses > output.logSo with this previous example, you can use cron to send daily newsletter:
# send newsletter at 08:00 AM, Monday through Friday
cron 0 8 * * 1-5 curl https://example.com/api/rest/daily | newsletter-ses > daily-`date +%Y%m%d_%H%M%S`.logWhen using the CLI, you can use the config list.sendReportTo to automatically send report when the sending job is complete:
const config = {
ses: { ... },
lists: [
{
...
sendReportTo: [
'admin@example.com'
]
}
]
}const newsletter = require('newsletter-ses')
const config = require('./config.json')
newsletter.configure(config.ses)
.send(config.lists)

console.log(`Failed to get send quota`, e)
