May I suggest to give a try to our newsletter plugin Jackmail Newsletter ?
What differentiate us from other newsletter plugins, is that we do have our own smtp server inside the plugin. So you don’t have to fiddle with settings or sending by package of 100 per hour, or to leave your lovely WP dashboard to create through another website.
It’s all in (like Adidas would say).
Plugin is free
Support is free
Updates are free
All features are included
We grant 3,000 emails per month for free (100/day as a limit for the free version).
And above, you have cheap prices.
Hope you’ll love it
