Description
MBX Reach is an email marketing service for people who write to an audience: newsletters, releases, announcements. This plugin puts one of your MBX Reach signup forms on your WordPress site.
- A block, “MBX Reach signup form”: pick the form, the button text and whether to ask for a first name, and see the real form in the editor.
- A shortcode for everywhere else:
[mbxreach form="frm_0123456789abcdef01234567" button="Subscribe" name="yes"], with your own form’s id. In the block editor it goes in a Shortcode block; a Code block only shows the text. - A default form id under Settings MBX Reach, so blocks and shortcodes can leave the id out, and a list of the other form ids authors may use.
The form posts to mbxreach.com, so the list it feeds and the tags it applies are whatever the form has in your MBX Reach panel. A signup that comes from another site, as the plugin’s do, always confirms by email, whatever the list’s double opt-in setting: the visitor sees a page asking them to check their inbox and joins when they click, so the form’s own redirect and thank-you message are not shown for it. Each form also accepts a limited number of new signups an hour from other sites; past it, visitors are asked to try again later. Nothing is stored on your site except the form ids you set, and the plugin loads no script from us on your pages.
You need an MBX Reach account to use it: https://mbxreach.com/
External services
This plugin renders a form whose target is mbxreach.com, the email marketing service operated by MediaBoxEnt Technologies. When a visitor submits the form, their browser sends the email address they typed, the first name if you asked for one, and (as with any web request) their IP address and browser details to mbxreach.com, where the signup is recorded in the audience of the MBX Reach account that owns the form. Nothing is sent until the visitor presses the button; merely viewing a page with the form sends nothing to us.

Installation
- Install and activate the plugin.
- In your MBX Reach panel, open Signup forms and copy the id of the form you want (it starts with
frm_). - Either paste it under Settings MBX Reach as the default, or put it in the block or the shortcode on the page.
- In the block editor, add the “MBX Reach signup form” block, or a Shortcode block with the line from the form’s page in your panel. A Code block shows the line as text instead of the form.
FAQ
-
Where do I find the form id?
-
In your MBX Reach panel, under Signup forms, open the form: its page shows the id and the hosted address.
-
Can visitors confirm by email first?
-
They always do. A signup from another site is confirmed by the person clicking the email MBX Reach sends, whether or not the list asks for double opt-in, so nobody can put an address on your list that its owner did not confirm.
-
Who can place a form?
-
Anyone who edits posts can place the default form and the other form ids an administrator lists under Settings MBX Reach. Any other form id shows only in content by someone allowed to publish unfiltered HTML (administrators and editors on a single site), so an author cannot collect your visitors into an MBX Reach account of their own.
-
Does the plugin style the form?
-
A few lines, so it looks tidy out of the box: a row with the fields and the button, in MBX Reach’s colour. Override
.mbxreach-formin your theme to match your site. -
Does it load anything from mbxreach.com on my pages?
-
No. It renders plain HTML. The only request to mbxreach.com is the one the visitor makes by submitting the form.

Changelog
1.0.10
Clearer steps on the settings page: where the shortcode goes in the block editor, and a complete example.
1.0.9
Authors can place only the default form and the ids an administrator allows; the alignment and CSS class set on the block reach the published page; the block’s default texts translate; the editor preview no longer submits; a mistyped id in Settings keeps the previous default; the hidden anti-spam field stays hidden without the stylesheet; uninstalling on a large network no longer walks every site in one request; and the readme says how signups from other sites confirm.
1.0.8
A block or shortcode with an empty form id shows the default form from Settings again, instead of nothing.
1.0.7
Deleting the plugin on a multisite network removes its setting from every site, and a form id followed by a line break is no longer accepted.
1.0.6
Require WordPress 6.3 (the block uses API version 3) and let the editor labels translate via language packs.
1.0.5
Harden the form-id check to the exact hosted format, add a direct-access guard to the asset manifest, and correct the note about where spam checks run.
