Diagnostics work, but test only works for some emails

Probably the newsletter contains something that trigger a spam filter. Try with a blank newsletter with only few line of text and with tracking disabled.

Hi there,

Firstly can I say AMAZING plugin. I think your plugin is one of the only ones out there that allows you to paste in custom html seamlessly and send via SMTP all from the wordpress dashboard. Awesome stuff!

Im not sure if its a bug or not but I was trying to send test emails to check everything was being sent ok. Every time I tried to send a test nothing was happening, I checked on mandrill but nothing was leaving the WP dashboard. I couldn’t work out why tests were not being sent as sending normally was fine.

After 2 days of trying to work it out, all it was – if you leave the Subject box blank, the test email will not send out. So for anyone else pulling there hair out… just enter ‘Test’ or something into the subject and it sends out fine!

But again, fantastic plugin…im building totally custom html emails with mailstyler, then simply copy pasting the code into Newsletter and sending via mandrill. Works perfectly!

Many, many thanks!

Ops, I emptied the subject field since few user reported they experience of sending newsletter with “Here the subject” as subject… but I forgot to show a warning when a test is sent about empty subsjects.

Thank you, I’ll fix it asap!
