I’ve already been using external SMTP for sending out my newsletters – but I keep getting e-mails from readers who said they are not getting them. My understanding, from reading here and elsewhere, is that Postman is a more reliable way to do this.
I can’t figure out how to configure it. Because in the support docs it says:
Probably the most famous is Postman SMTP. Using WordPress as first choice to send emails lets bloggers to control how each email send by their site is delivered.
So, using “WordPress First” activates Postman? Because in the settings page (/wp-admin/admin.php?page=newsletter_main_main) under the heading, “Send email directly” there is a note that says:
Instead of using WordPress email are sent directly by Newsletter. This enable the textual part of newsletters and the content encoding setting. Keep at “No” if you’re using ans SMTP plugin like Postman. Read more.
Then I found this reply, in these forums…
If you want to use postman, keep the direct send and the smtp disable in Newsletter.
