You will need the extension tt_address and direct_mail for this extension. Users can subscribe to your newsletter, if you uses addresses from tt_address. fe_users is not supported today, but it is planed.
You will find 2 folders in the templates-folders: Email and Log. In the Log-folder are the form-templates. If a user submits the form, the entries lands in the table tx_fpnewsletter_domain_model_log. Only if a user verifies his email-address, his entry will be copied to the table tt_address.
In the Email-folder you find the templates for the email to use user. Its the email for verifing the email-address. And there are email-templates for the admin: UserToAdmin is sent before verification and SubscribeToAdmin is sent after the email verification. If you want to change the text of the email, copy the templates e.g. to fileadmin and set the new path via TypoScript setup:
plugin.tx_fpnewsletter.view.templateRootPaths.1 = fileadmin/bsdist/theme/tmpl/fp_newsletter/Templates/
There is a text and a HTML version. And there is an english and a german version of this template. The translate-ViewHelper can not be used in this templates thats why you need to create a template for every used language. The default template is in german. SubscribeVerify1.html contains the english text. You can use this email-templates like this:
SubscribeVerify<LANGUID>.html and SubscribeVerify<LANGUID>.txt
Only for the language 0 you must remove the number. For the language 1 SubscribeVerify1.html is used automatically.
It does not work correct. What can I do?
Maybe you need to set the storage PID twice: via plugin and via TypoScript. Note, that you need an own page for the newsletter unsubscription.
The domain is missing in the email. Why?
TYPO3 9 ignores the parameter absolute=”1”? Or you have not added a domain in the backend? Add the domain by your own in that case.
I don´t want/need a log entry. Can I avoid that?
Not at all. You can add a task to your scheduler: select the task Scheduler / Table garbage collection. Select there the table tx_fpnewsletter_domain_model_log and set the days after the entries should be deleted. If the CronJob is running, the task will delete all old log entries.
