I am desperatley looking for a working Email-Client for oxwall/skadate. The build-in mass mailing tool cannot handle the amount of users I have. As soon as you have thousands of users, the oxwall-mailing tool gets a server time-out error. 

Oxwall is using the tabel ow_notifications_send_queue and then cron sends 50 Emails every 5 minutes. --> As you can see, that leads to server time outs

Which sending method is your plugin using and can it handle thousands of Emails?

I know from your other plugins that you make quality work so I have my fingers crossed your plugin may be the solution to my problem!

Thank you

Matthias
