Ok so I found what is causing the problem:

In <PLUGINS ROOT>/sendpress/classes/class-sendpress-manager.php

Around line 415, static function send(…)

$sender = $sendpress_sender_factory->get_sender($method), is assigning null value to $sender, which is causing the next line to fail:

if( $sender != false ){
// DO THE SENDING
}

However, commented out below this block is:

$website = new SendPress_Sender_Website();
return $website->send_email( $to, $subject, $body, $text, $test, $sid , $list_id, $report_id );

Which works, so the net function for me, is like this:

—

static function send($to , $subject, $body, $text, $test = false, $sid=0 ,$list_id = 0, $report_id = 0 ){

global $sendpress_sender_factory;
// $senders = $sendpress_sender_factory->get_all_senders();
$method = SendPress_Option::get( ‘sendmethod’ );
$sender = $sendpress_sender_factory->get_sender($method);
if( $sender != false ){
if( empty($text) || $text == ” || empty($body) || $body== ” || $body == ” “){
SPNL()->log->add( ‘Email Skiped’ , ‘Email to ‘.$to.’ did not have any Text.’, 0 , ‘sending’ );
return false;
}
return $sender->send_email( $to, $subject, $body, $text, $test, $sid , $list_id, $report_id );
}

$website = new SendPress_Sender_Website();
return $website->send_email( $to, $subject, $body, $text, $test, $sid , $list_id, $report_id );

}

It looks a little different (formatting, icons etc…), as I think you are using the ‘pro’ version, which I am not, but that is the option which I have selected, ie, using my website to deliver the messages (NOT google, or anything else).

I should also say (again) that sending of the opt in emails have always been working fine, when using the explicit ‘subscribe’ form, the problem was when this process should have been triggered with easy digital downloads checkout via this plugin https://wordpress.org/plugins/edd-sendpress/
