i want to ask about mail type
there is not clear documentation
Send your generated content as E-Mail to a group, mailing list or something else
ok what groups and mailing lists?
when i try to insert something else except a common email it does not support and cannot save.
i like the mailing list option but where do i find mailing lists? and what should i insert there?
The mail channel allows to simply send posts to an email recipient.
The extension does not implement mailing list management. We recommend to integrate any popular package. For instance, many hosting providers have mailman in CPanel. Alternatively, you can create a Google group or an internal mailing list in your mail service.
If your hosting provider is using mailman and postfix then you cannot create mailing lists.
In such case you can use mail service from other mail provider like Google and easily manage your mailing lists.
