An inline survey lets recipients answer right in the email, which makes quick feedback effortless and shows you respect their time. MailMachine supports embedding a Typeform Opinion Scale survey via its HTML. This guide covers it.

## Build the survey in Typeform

1. In Typeform, create a form from scratch.
2. Choose the **Opinion Scale** form type - the only type currently supported for inline email embedding.
3. Edit and **publish** your form.
4. Click **Share**, then **Embed in an email**, and **Get the code**.

## Add it to your campaign

1. Drag an **HTML** content block into your email.
2. Position it where you want the survey.
3. Paste the Typeform code into the **Content Properties** panel on the right.

The survey now links directly to your Typeform, collecting responses there.

## Troubleshooting

**The survey doesn't display** - use the Opinion Scale type, paste the complete HTML, and test across email clients.

**The HTML doesn't work** - use the HTML block (not a text block), paste into Content Properties (not directly in the editor), and remember email clients strip JavaScript.

**Low response rates** - keep it to one to three questions, place it prominently, and use compelling copy to invite a response.

**No data collecting** - check your Typeform account is active and the form is published (not a draft), and test the form's own link.

**Client compatibility** - some clients don't support embedded forms, so include a fallback link to the web version.
