Using Merge Fields to Personalize your Emails

Merge fields let you drop subscriber data straight into an email. Mailblast supports four built-in fields:

FieldWhat it inserts
{{ email }}The subscriber's email address
{{ first_name }}The subscriber's first name
{{ last_name }}The subscriber's last name
{{ unsubscribe_url }}A unique unsubscribe link for this subscriber

Wherever you write email content - in a template, a campaign, or an automation - the Merge Fields tab lists these fields for reference.

Basic usage

Type the field's tag anywhere in your content, for example {{ first_name }}. When the email is sent, Mailblast replaces it with the value stored for each subscriber.

Liquid template support

Mailblast uses Liquid under the hood, so you can go beyond plain tags by adding filters and conditionals.

Common examples

Set a default value if the field is empty:

Dear {{ first_name | default: "customer" }}

Capitalize the first letter:

Dear {{ first_name | capitalize }}

Extract the first word (useful when first and last name are stored together):

{{ first_name | split: " " | first }}

For advanced filtering and conditional options, refer to the Shopify Liquid reference.
