Question 1

Why my email model is not being sent directly?

Accepted Answer

Assuming  that you have no general issue with your SMTP server, keep in mind that the pluging uses the WP-Cron scheduler to send emails in small batches at regular intervals.
WP-Cron is a built-in cron job (wp-cron.php) in WordPress that runs every time someone visits the website.
In most cases emails will be delivered fast unless you have a website that has little traffic or a very large mailing list.
For websites with low traffic, we recommend to run wp-cron.php externally via Crontab.

Question 2

Does the plugin provide segmentation?

Accepted Answer

Yes the plugin has a built-in segmentation system through email lists to filter the core list of users.
Furthermore, any plugin that filters the list of users can be used to &ldquo;segment&rdquo; your newsletter.

Question 3

Does the plugin provide tracking?

Accepted Answer

In order to keep the implementation simple and lightweight the plugin does not provide advance tracking for now.
It does add utm_source parameters to urls compatible with most Analytic softwares.
