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.
Setup
Live in about two minutes
Install the EmailSendX plugin for WordPress and paste your API key.
Open the block inserter. The EmailSendX category sits just under “Text” — or simply search “emailsendx”.
Insert “EmailSendX Form” or “EmailSendX Newsletter” and pick your form or list in the sidebar.
What you get
Made to feel native in the Block Editor.
What you see is what they get
The form in your editor isn’t a placeholder — it’s the real thing, your styling and all. No publishing just to check how it looks.
It picks up your brand colours
Choose a colour from your theme instead of typing a hex code. Change that colour later and every form on your site follows along by itself.
Works anywhere blocks do
Posts, pages, patterns, templates. Put a signup box in your footer once and it shows up across the whole site.
No weight on pages without a form
Pages that don’t have a form don’t load a single extra byte from us. The rest of your site stays exactly as light as you built it.
Styling
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.
