If you have an email built outside Bookboost, whether hand-coded, exported from a design tool, or delivered by an agency, you no longer have to recreate it in the drag-and-drop editor. Paste HTML mode lets you drop the finished HTML into a campaign and send it as it is, and keep editing the markup whenever you need to.
The three ways to author an email
When you build an email campaign, you choose how to write the content. There are now three modes:
Message: a plain body, the same style used for SMS.
Editor: the drag-and-drop editor, where you build the email from blocks.
Paste HTML: a text area where you paste and edit your own HTML.
Paste HTML is the newest of the three. Pick it when your email already exists as HTML and rebuilding it in the Editor would be wasted effort.
Before you start
You are building an email campaign. Paste HTML mode is not available on other channels such as SMS.
You have your finished HTML ready to paste.
How to use Paste HTML mode
1. Open the email campaign you are working on, or create a new one, and go to the step where you choose the email content.
2. In the authoring mode toggle, select Paste HTML, and then click on Confirm. You will see it alongside Message and Editor.
3. Paste your HTML into the text area. It is a full-width monospace field, so you can keep tweaking the markup directly.
4. Keep any personalisation tokens in your HTML. They resolve at send time, the same as they do in the Editor.
5. Use the campaign preview to check how the email renders, then continue through the normal send steps.
Switching between modes
Each mode can only keep the content it understands, so switching always asks you to confirm first.
Moving from Paste HTML to Message or Editor prompts you before it discards your pasted HTML, because those modes cannot hold raw HTML.
Moving from the Editor to Paste HTML prompts you before it discards your drag-and-drop design.
Your drag-and-drop design is kept when you move away from the Editor and come back to it. The HTML you type in Paste HTML mode is not carried into the other modes, so copy it somewhere safe before switching if you might want it again.
What to expect
Your HTML is sent as you wrote it. The campaign sends the markup directly, so what you paste is what recipients receive.
Personalisation tokens resolve. Tokens written into your HTML are filled in at send time, exactly as in the Editor.
The preview reflects your HTML. Use it to confirm the email renders correctly before you send.
What Paste HTML mode does not do
No syntax help. The text area is a plain monospace field with no syntax highlighting, autocomplete, or HTML checking. Check your markup carefully before sending.
No importing an Editor design. You cannot load an email built in the drag-and-drop Editor into Paste HTML mode as a starting point.
Email only. The mode does not appear for non-email channels.
Common questions
Will my personalisation tokens still work?
Yes. Tokens written into your HTML resolve at send time, the same as they do in the drag-and-drop editor.
Can I start from an email I built in the Editor?
Not today. Paste HTML mode does not import a drag-and-drop design as a starting point. You would paste in HTML from your own source instead.
What happens if I switch modes by mistake?
Bookboost asks you to confirm before it discards anything. Nothing is lost until you confirm, but as a habit, copy your HTML somewhere safe before switching.
Is Paste HTML available for SMS or other channels?
No. It is available for email campaigns only.
I do not see Paste HTML. Why?
The mode is available to organisations with the Import / Export Design feature enabled. If you do not see it, contact support.
