# Send emails by row

> Send one personalized email per row of your dataset using Parabola's Send emails by row step. Up to 75 emails per run, with merge tags from any column.

The **Send emails by row** step sends one email per row in your dataset, using the email address in a column you choose. It's the right step when you need to notify a list of recipients with personalized content — chargeback alerts to vendors, status updates to customers, daily summaries to store managers.

Up to **75 emails per run**. All messages send from `team@parabolamail.io` with a "Powered by Parabola" footer.

## Using variables

Personalize subject and body with merge tags. Tags reference column names from the input table using `{curly braces}`.

For example, with columns named "Name" and "Order ID":

* **Subject:** `Your order {Order ID} has shipped`
* **Body:** `Hi {Name}, your order is on the way!`

<Note>
  Cell values can contain literal curly braces without breaking anything. Parabola only evaluates merge tags in the subject and body template fields, not in your data.
</Note>

If you reference a tag that doesn't match a column, the error message tells you which tag is invalid and which field (subject or body) it's in.

## Helpful tips

* **HTML formatting:** select **HTML** in the Body Format. Common tags like `<br>`, `<b>`, and `<a>` are supported.
* **75-recipient limit per run.** Filter or batch upstream if your list is larger.
* **One email per row.** If you need to send a single email with a file attached to a fixed list, use [**Email a file attachment**](/product/integration/email-attachment) instead.
* **Watch for empty rows.** If the email column has blank cells, the step still tries to send. Filter blanks out with [**Filter rows**](/product/transform/filter-rows) first.
* **Schedules apply to the parent flow.** Pair this step with the flow's schedule trigger to send recurring digests.
