Email Deliverability ratings
How we compare these two
Every figure here is pulled from the WordPress.org plugin API every day at 03:00 UTC, for both plugins in the same run, so the two are always read on the same day. We compare only what the directory reports: active installs, the rating and how many reviews stand behind it, the last release date and, once we have a month of history, downloads over the last 30 days. Ratings are only called a win above 50 reviews each, because a handful of five-star reviews is not evidence. Nothing is weighted into an overall score, no measure is worth more than another, and neither FluentSMTP nor Email Deliverability can pay to appear here: the pair exists only because both plugins reached the Email Plugins top 10.
