The Classic editor works like a word processor. The Plain text editor sends words only. The HTML editor is for people who write their own code. The top bar, preview, test send and version history are explained in Choose an email editor.
Classic editor #
It always makes a single column. The left panel, Email settings, holds:
| Setting | What it does | Default and limits |
|---|---|---|
| Use brand kit | Applies your saved colours, font, button style and logo | Shows when a brand kit is saved |
| In the inbox > Preview text | Line shown after the subject | |
| Layout | Boxed (card on a coloured page), Centered (no card), Letter (plain, like a personal email) | |
| Text | Font, Size (px), Line height, Text colour, Link colour | Size 12 to 24, default 16. Line height 1 to 2.5, default 1.6 |
| Colours | Brand colour, Page background (Boxed only), Card background (Boxed) or Background | |
| Buttons | Button colour, Button text colour, Corner radius (px) | Radius 0 to 40, default 6 |
| Logo | Add a logo / Replace / Remove, Width (px), Alternative text | Width 40 to 600, default 160 |
| Footer > Add a footer | Your own footer. Off: Hive Mail adds its standard footer to marketing emails | When on: Text, Unsubscribe link text, Preferences link text, colours, Alignment, Show business name and address, Show a link to the preferences page |
| More | Content width (px), Page title, Language code, Direction | Width 320 to 900, default 600 |

The right panel, Tips, shows the "Check before sending" notes. Click a picture and it becomes Picture, with Alternative text and Width (16 to 1200 px, empty is full width).
- Click where it says "Start writing your email…" and type. The formatting bar has: paragraph and Heading 1 to Heading 3, Bold, Italic, Underline, Text colour, Link, Button, lists, alignment, Quote, Divider, Image,
{{ }}for merge tags, Clear formatting, Undo, Redo and Edit the HTML source. - For a link, select text, press Ctrl+K, type the address and click Apply. Allowed:
https://,mailto:,tel:or a merge tag such as{{site_url}}. - For a button, click Button: selected text becomes a button, otherwise a centred "Click here" is inserted. Or tick Show as a button in the link box.
- For a picture, click Image and choose one from the media library.
- Edit the HTML source shows the code; Apply keeps only allowed tags.
Allowed: paragraphs, headings 1 to 3, lists, quotes, dividers, bold, italic, underline, text colour (hex only), links, buttons, pictures and line breaks. Anything else you paste is cleaned away. A Classic email never has columns.
Plain text editor #
It sends a real text/plain email: no design, pictures or buttons. Tabs: Settings, Write, How it reads.
| Setting | What it does | Default |
|---|---|---|
| Also send a simple HTML version | Adds paragraphs and clickable links for mail apps that prefer HTML | Off |
| Track clicks on links | Replaces links with tracked addresses. Opens cannot be tracked in plain text | Off |
| Language code | Language of the email | en |
| Direction | Left to right or Right to left | Left to right |
- Type in the box "Write your email…". A guide line marks 72 characters.
- Put each link on its own line. Click
{{ }}for merge tags such as{{first_name|there}}. - If lines are too long, click Wrap long lines (the number in brackets counts them). Words and addresses are never split.
- Check How it reads: your text with sample details and the unsubscribe line.
If you leave out the unsubscribe address, Hive Mail adds an unsubscribe line to marketing emails, with the business name and address, as plain text.

HTML editor #
For people who know email HTML (tables, inline styles). Tabs: Settings, Code, Preview. The code box is WordPress's own code editor; the preview updates about a third of a second after you stop typing.
| Setting | What it does | Limit |
|---|---|---|
| In the inbox > Preview text | A hidden first line in the body | 255 characters |
| Page > Page title | Title of a fragment | 150 characters |
| Language code, Direction | lang and dir of a fragment |
en, Left to right |
| Import an HTML file | Replaces the code with a file | .html or .htm, 500 KB |
- Paste or write your HTML. A full document or a fragment works; a fragment gets a minimal page around it. The code can be up to 512,000 characters.
- Insert merge tags with
{{ }}. They work in text and in link addresses, likehref="{{unsubscribe_url}}". - Put
{{unsubscribe_url}}or{{unsubscribe_link}}in your footer, or Hive Mail adds its own. - Check Preview and use Send test.

Hive Mail always removes scripts, iframes, objects, embeds, forms and their fields, buttons, selects, event handlers such as onclick, and javascript: addresses. The head, <style>, tables and Outlook comments stay as written. If your account lacks the unfiltered_html permission (normal below administrator), the code is cut to a safe list of tags and styles when you save, and the editor says so.
Warning: An HTML email can only be switched to Plain text, never back to blocks. Keep a copy of your code.
