    Plugin was working smootly before updating to the latest version; on the  configuration page I have the Max emails per hour setted on 1500.

    But despite this setting (I’ve tried to change it many times) newsletter engine is sending only 40 emails per 300 seconds.

    Is this my problem or is something with the latest update?

    Thanks

    Enable logs on diagnostic panel and verify if they report a “time limit reached”. If so, your php execution time is too low to support an higher sending rate.

    Thanks, I’ve had it enabled but I see no errors.

    I’ve tried to change the max email per hours from 1500 to 1505 and it worked, but just once (it sended 150 emails), then it turned back to send 40 emails…

    These are my parameters, anything I should change?

    Thank you

    Sorry for double post,

    you’re right Stefano.

    I’ve enabled debug info and I now see:

    07-02-2013 09:38:08 – INFO  – limits_exceeded> Max execution time limit reached

    I’ll change this parameter.

    Many thanks for your support.

    Ok, pay attention: if you’re running fastcgi, be sure to set the max time on fastcgi as well…

    Hi – I’m seeing this problem too, a very slow send rate.

    I’m using WordPress 3.4.2 and Newsletter 3.0.9.  I’m using google smtp to send the emails, using my Google Apps for Business account as the login credentials.  I use HostGator for my hosting on a shared server.

    It looks like I cannot change the PHP execution time setting via cpanel, although I suppose I could ask HostGator to change it and see whether they go along with that request.

    I would be happy to use SendGrid or something like that, but when I tried them a week or two ago, my emails were marked as spam by google in my own inbox.

    Are there other SMTP service providers that I could try?

    – Tim

    Hi very strange about SendGrid I never had my emails marked as spam with them. Be sure it’s not the content of emails triggering spam filters.

    Stefano.
