I wanted to have a go at the free version before switching to the premium one.
However, I am unable to send e-mails with the plugin.
I use Postman SMTP, along with my O365 SMTP credentials.
The test e-mails and debug from Postman are fine.
When I go to “Settings->Diagnostic”, I receive the following message :
Email sent with WordPress: SUCCESS
Email sent with Newsletter: FAILED (Undefined index: post_type)
When I go on “Status”, all is green but the first row : “Mailing”. It is red and there is the following error :
Last test failed with error “Undefined index: post_type”.
Could you please help me sort this out ?
