# Using Target-Form Merge Tags

Target-form merge tags let you pull values from the entries of your
chosen target form directly into your emails. This makes it possible to
personalize messages using data that wasn’t entered in the control form.

------------------------------------------------------------------------

## How It Works

- At the bottom of the merge tag dropdown, you’ll see a list of all
  fields from the target form.
- Selecting one will insert a merge tag with the `:meff` suffix (Mass
  Email Form Field).
- Example: `{First Name:2:meff}` will output the first name from the
  target form entry.

------------------------------------------------------------------------

## Special Cases

- **{meff:all_fields}**: Use this tag to display *all fields* from the
  target entry. The `meff:` prefix is part of the merge tag, but the
  output renders like a normal `{all_fields}` block (just for the target
  entry).
- **Other entry data**: Even fields not in the dropdown can be used by
  appending `:meff` to the merge tag name.
  - Example: `{entry_id:meff}` will output the target entry ID (useful
    for building links).
- Currently, the dropdown only shows form fields, but more entry
  properties (like ID, date created) are planned to be added.

------------------------------------------------------------------------

## Tips

- Use target-form merge tags to personalize messages with details the
  recipient provided earlier.
- Combine with deduplication rules to ensure the most recent entry’s
  values are used.

Target-form merge tags unlock deeper personalization by letting you
embed data from the audience’s own submissions into your messages.
