Block Editor (Gutenberg)
Opt-in form blocks for WordPress.
Two native blocks for the editor you already have. Insert a form, watch it render live while you edit, and colour it from your own theme palette.
Live in about two minutes
- 1
Install the EmailSendX plugin for WordPress and paste your API key.
- 2
Open the block inserter. The EmailSendX category sits just under “Text” — or simply search “emailsendx”.
- 3
Insert “EmailSendX Form” or “EmailSendX Newsletter” and pick your form or list in the sidebar.
The editor preview is the real form
These are dynamic blocks: the preview is rendered by the same code that runs on your live site, not a mock-up of it. What you see while editing is exactly what your visitors get — including your styling choices.
Uses your theme palette
The colour pickers take your theme’s own colours, not just hex codes. Pick “Brand” and the block stores the theme variable rather than a frozen hex — so if you change that colour in your theme next month, every form on the site follows automatically.
Works anywhere blocks work
Because they are ordinary blocks, they belong in the site editor, in patterns, in reusable blocks and in template parts. Drop a newsletter box into your footer template once and it appears across the whole site.
No build step, no bloat
The blocks are dynamic and server-rendered. The form stylesheet is only enqueued on pages that actually contain a form, so posts without one carry no extra CSS or JavaScript.
It should look like your site, not like a plugin
The block sidebar groups everything into Layout, Fields, and Button & text. Set the width, size and spacing; choose an outlined, filled or underlined field; pick a corner radius from square to pill; and hide labels for a placeholder-only look that screen readers can still read.
Because the colours accept theme variables, a form dropped into a dark section can genuinely inherit your dark palette instead of being hard-coded to a hex you have to remember to update later.
Questions about the Block Editor.
Everything else operators ask before adding EmailSendX to the Block Editor.
Yes. They are standard blocks, so they can be placed in templates and template parts in the site editor, saved into patterns, or reused as synced blocks. A newsletter box in your footer template appears site-wide.
No. These are native blocks for the default WordPress editor. If you also run Spectra, the same blocks work inside Spectra layouts, because Spectra builds on the block editor.
No. These are dynamic blocks — the markup is generated on the server at render time rather than saved into the post. That is exactly the class of block that does not suffer “this block contains unexpected content” errors after an update.
Yes. Every builder renders through the same shortcode, so a block, an Elementor widget, a WPBakery element and a pasted shortcode all produce identical output.
