Switching from Mailster: common questions
What is the best alternative to Mailster?
Email Subscribers is the closest match: it shares the same WordPress.org tags and has 50,000+ active installs with a 4.6 out of 5 rating.
Which Mailster alternative has the most users?
Newsletter, with 200,000+ active installs reported by WordPress.org.
Which Mailster alternative is rated highest?
Omnisend, rated 4.9 out of 5 by 169 reviewers. Only plugins with at least 50 reviews are counted.
Are these Mailster alternatives free?
Every plugin listed here is free to install from WordPress.org. Where WordPress.org marks a plugin as commercial, the developer also sells a paid version or add-ons, and that is shown on each plugin.
How are alternatives chosen?
Automatically, from WordPress.org data: plugins that share a category top 10 with Mailster score highest, then plugins that appear in the same WordPress.org rankings, then plugins with the same tags, weighted so rare tags count more than common ones. Plugins by the same author and plugins rated under 4.0 are left out.
How we choose these alternatives
Nothing on this page is picked by hand. Every day we walk the whole WordPress.org directory, then score every plugin against Mailster on three signals: sharing a category top 10 counts most, then appearing in the same WordPress.org rankings, then carrying the same tags, with rare tags counting for more than common ones like "wordpress". Plugins by the same author are excluded, so an author's own add-ons cannot fill the list, and so is anything rated below 4.0 or with fewer than 100 active installs. The ten highest scores are what you see, in that order. Full methodology.
The bottom line
Email Subscribers is the closest match to Mailster by the data we track, and Newsletter has the widest reach with 200,000+ active installs. Newsletters shipped the most recent release, on October 20, 2026. The list is rebuilt every day from WordPress.org, so a plugin that stops being maintained drops out on its own.
