Frequently Asked Questions

Common questions about Mailster Dummy Mailer

No. Mailster Dummy Mailer is an addon for the Mailster Newsletter Plugin and requires Mailster 4.0 or newer.

No. It simulates delivery and (when enabled) campaign engagement. Messages are not delivered to real inboxes.

It adds a DummyMailer delivery method to Mailster. When selected, sends are simulated using your success and error rate settings, and optional cron simulation can generate opens, clicks, unsubscribes, and bounces toward the rates you configure.

Not while DummyMailer is the active delivery method. Use it only on development or staging sites, or when you intentionally want no real delivery.

Yes. In the DummyMailer delivery tab you can enable rate simulation and set open, click, unsubscribe, and bounce percentages, plus success and campaign error rates for the send itself.

Simulation walks campaigns and subscribers to apply engagement events and can be memory-intensive. At least 256MB of PHP memory is recommended.

For Mailster and this addon, see mailster.co and the WordPress.org support forum.
