PHP script to export web push subscription stats from SendPulse

Steps to use:

1. Download the archive.
2. Exctract it.
3. Enable API access in your SendPulse settings.
4. Make the needed amendments to the script:
1. set your API_USER_ID and API_SECRET.
2. add the list of your domains into $country_mapping variable
5. Run the script with php index.php > senpulse.csv (PHP 7+ needed):
6. Wait for the script to finish (average speed is ~60k subscribers per hour).

Important! The exported data  isn't enough for transfering yoour subscribers to other web push service provider. It's good only for stat analysis.

Someone else's thoughts on comms frequency

Last week I've been speaking with a marketing manager from another company. She told me a remarkable thing:

"Andrey, clients who are not engaged with our product recently should be targeted by our email notifications more frequently in order to make them buy our stuff"

I've been shocked, to be honest.
