I have a dedicated service only for sending emails, where I use the Mainenable program as a smtp mail server.
I would like to use this machine with "Newsletter" but I do not know how to set the smtp settings in the plugin installed on my wordpress site.
What should I write next to each question field?
Enable the SMTP?
SMTP host / port host:
Authentication user:
password:
Insecure SSL Connections
The SMTP settings should be provided by who setup your SMTP settings. We cannot know which is your username, password and host. They should give you exaclty what's required in the SMTP panel.
