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.

​
Setting up the step

1
Add the step to your flow by dragging it onto the canvas.
2
Connect it to the step that holds your column of email addresses.
3
Open the step to configure settings.
4
Recipients: pick the column with the email addresses.
5
Body Format: plain text or HTML.
6
Subject and Body: required. Personalize them with merge tags from other columns using {curly braces}.
7
Reply To: the address replies should go to.
Send emails by row step configuration with subject, body, and reply-to fields

​
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!
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.
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 instead.
  • Watch for empty rows. If the email column has blank cells, the step still tries to send. Filter blanks out with Filter rows first.
  • Schedules apply to the parent flow. Pair this step with the flow’s schedule trigger to send recurring digests.
