  2. Meow Mailer 0.3.3

    • Add: WordPress (Server Mail) as a provider, which sends like WordPress but uses your Sender settings, the log, the fallback and test emails.
    • Add: Short subtitles under the Email Provider and Sender settings blocks.
    • Update: New Meow Apps dashboard in the shared common code.
    • Update: Clearer License tab that explains Pro to free users and invites Pro buyers to activate.

    • Update: The empty chart and success rate on the dashboard now say that nothing matches the filters, instead of that nothing was ever sent.

    • Fix: A host’s own mail relay keeps working when an email goes out through the WordPress route.
    • Fix: The log pager is hidden when there are no results.
    • Fix: The busiest day shown under the chart is the real one, instead of the top of its scale.
    • Fix: The None provider card no longer says nothing is logged, since WordPress’s own emails are still logged.

  3. Meow Mailer 0.3.2

    • Update: Meow Mailer now works alongside WordPress Mail Queue, keeping its sending pace while each email still goes out through your provider.
