Don’t want to publish all of your posts at once but hate manual scheduling/rescheduling? Post to Queue comes as a solution. You just put posts to queue and they’ll be published automatically when chosen time passes since last published post of that post type. It’s even possible to choose days of the week and hours of the day when those posts will be published.
Post to Queue is like Buffer for WordPress, just better.
It requires that cron runs regularly to be able to publish posts on time.
Post to Queue code is partly based on a code from plugin <a href="https://wordpress.org/plugins/automatic-post-scheduler/" rel="ugc">Automatic Post Scheduler</a> by <a href="http://tudorsandu.ro/" rel="nofollow ugc">Tudor Sandu</a> and a code from plugin <a href="https://wordpress.org/plugins/metronet-reorder-posts/" rel="ugc">Metronet Reorder Posts</a> by <a href="http://www.ronalfy.com/" rel="nofollow ugc">Ronald Huereca</a> and <a href="https://geek.hellyer.kiwi/" rel="nofollow ugc">Ryan Hellyer</a> for <a href="http://www.metronet.no/" rel="nofollow ugc">Metronet Norge AS</a>.

If you are sending large volumes of emails this is the plugin you need.
Generally wordpress emails are best sent by a third party, like gmauil or Sendgrid. But connecting and sending a large number of emails to third parties will slow your visitor experience down.
Unless those emails are sent in the background. This plugin does that.

LH Email Queue and Log

LH Email enables you to queu your emails so they are sent asynchronously.
