Main Configuration

This page will help you during the configuration of Newsletter: we want you to get the most out of it! Here, you’ll find an explanation of the parameters you need to set up when you start using the plugin. 

If you have any doubts, please use the support forum to find answers or ask questions!

1. The Newsletter dedicated page. 

Newsletter needs a page to show service messages, like the activation, the welcome and goodbye messages. If you followed the configuration wizard, that page is created and pre-configured for you automatically.

You can find it in your blog page list, where you can also personalize its design. There is just one simple rule: the Newsletter page should be a regular WordPress page that contains only the [newsletter]shortcode!

If you want to use another page, you have to add the shortcode and select it on the Newsletter “General Settings” as the dedicated page, so the plugin knows where to redirect the subscribers when they perform an action and when service messages need to be shown. 

Important notes

  1. If the selected page is deleted or unpublished or if you remove/change the [newsletter] shortcode, it may appear a 404 error page. In this case, check the configuration!
  2. Pay attention not to use any other Newsletter shortcode on the dedicated page, as for example [newsletter_form]: although the page may look exactly the same, they won’t show the service messages! 
  3. If you want to customize the layout of the Newsletter dedicated page, we suggest checking if your theme has the option to change the layout at the page level. You can even create a custom template page in your theme (or in a child theme) or use the same layout of your landing pages, which are usually simpler than the regular ones.
  4. If you add other text to the dedicated page, it will be shown every time a service message is displayed, so be careful!

2. The sender

The sender is “who” is sending emails to your subscribers. With “who” we mean a name (for example your name if yours is a personal blog or your brand name, if it is a company blog) and an email address. When you installed Newsletter for the first time, you configured this up through the welcome wizard. 

Usually, the best choice is to use an email address from your domain with a real mailbox behind. Some providers do not allow to send emails with a fake sender (for example 

Important notes:

  1. Never use as email address from free services as gmail, yahoo, aol, outlook and so on. Your blog (server) is not allowed to send emails for those accounts!
  2. Always perform some email tests. Go on the Newsletter Dashboard and click on “Status” to check if everything is set up correctly, to perform a test and to verify if there are any delivery issues. 
  3. Sometimes it happens that your emails are sent with a different email address or name from the one you’ve chosen on Newsletter. This may happen for two reasons:

    a. You have a SMTP plugin installed or a plugin that redirects all emails sent from your blog to an external delivery service. Those plugins let you set up an email and name and can eventually overwrite the ones you set on Newsletter. Have a look and disable those options.

    b. If the problem persists, ask your provider if they are enforcing the sender on emails. Some providers do it! Find more tips here.

3. Return path

The return path is an email address where all the undelivered messages are returned. If you set a real mailbox as the return path, remember to check it to remove from your lists the addressed that are no longer reachable. The Bounce Addon can do it for you automatically! 

If you use a third party delivery service (Sendgrid, Amazon SES, Mailgun, …) integrated with one of our addons, you don’t need to setup the bounce checking it is provided automatically.

Keep in mind that some providers do not allow to specify a return path address since they forces their own. 

4. Reply to

The Reply to option is an additional service. You can specify an email where to receive messages if a subscriber wants to reply to your newsletter. 

Important notes: Be sure that you specify a valid email address. If possible, use an email address from your domain. 

5. Delivery speed

Max emails per hour

The Newsletter plugin has a delivery engine that sends out emails with a speed up to the configured value. That upper limit avoids email dropping or blocking by providers.

You should always ask your provider which is the limit they will tolerate.

Even on a private server, setting this limit to a reasonable value is a good idea to avoid saturating the server with queued email.

It is not granted Newsletter can send exactly at that speed it is only an upper limit. Slow servers, so connections, slow SMTPs can set the real speed to a much lower value.

On Newsletter “System” panels you can find an average delivery speed computed from values collected during real deliveries. Those statistics report how many seconds are required to send (by average) a single email and so the speed the plugin can reach.

It is even reported if Newsletter needs to prematurely stop a delivery batch due to limits imposed (by server configurations) on the maximum job duration in seconds (for example there are servers configured to run a single job for a maximum of 30 seconds but the delivery of 100 emails could take more than that).

To have even more evidence of the internal delivery process, the log level on Newsletter main settings can be set to debug and in the “System” panel some logs should be available. Of course reading those logs require a bit of technical knowledge of the plugin internals.

See the Delivery Engine page for more information about the delivering process.

Advanced settings

Here you can modify some other aspects of Newsletter, including roles, tracking and debug. 

Custom CSS

This function allows advanced users to personalize some aspects of the design of forms, fonts, buttons etc. Just write down the code and you are good to go. 

Allowed Roles

This option allows you to choose who can access Newsletter. The options are based on the roles you configured on WordPress (e.g. if you select Editors, every user with the Editor role will have access to Newsletter). Additional roles can be created by Teams or other plugins. 

Note: some functionalities of Newsletter or Addons are available exclusively to the administrator role since they usually need a one time configuration and may contain sensible information.

Log level

Every Newsletter component (and even the professional addons) can log their internal state and errors. The log level selects the level of detail those log should have. 

Debug level can create huge log files. Log files are listed at the bottom of the status panel, where you can download or delete them. Log files are rotated monthly.

Tracking default

It sets the default open and clic tracking for new newsletters. The value is just a preset, it can be changed on every single newsletter before sending.

IP addresses

This option allows you to select if the IP address of your sites should be stored, anonymized or not stored at all. The IP address is collected at the time of the subscription and is useful to have detailed statistics (read and click tracking). Anonymized IP addresses are changed by removing the last number of the address and replacing it with zero. 

Flood control and geolocation are affected by this settings. If you decide not to store IP addresses, geolocation and flooding check will be disabled. If you keep the IP address anonymized, the geolocation will work, but with less precision. 

Debug mode

The debug mode is used just for support operations.

It intercepts even the PHP errors and logs them in a specific log file. When in debug mode, an admin warning is always present and the use should be limited to debug sessions. Do not let this mode always active!

Email encoding

This option defines how a email message is internally encoded. Usually, the default options works perfectly. Sometimes, old mail servers with have problems in managing messages with long lines: in this case, try to set it to “base 64”. 

Do not change this option if you are using an integration extension to send emails (e.g. Amazon SES, Mailjet, Sendgrig etc.)


This option enables Newsletter to execute shortcodes that you put inside your newsletter. Of course shortcodes can generated invalid HTML for an email, so use with care.
