Macros

Macros are dynamic placeholders that Sendmachine replaces when an email is sent. They allow you to personalize emails, insert recipient data, generate links, and display conditional content - all from a single template.

Macros make it possible to send one email that looks different for every recipient.

What are macros?

A macro is a placeholder written in the following format:

[[MACRO_NAME]]

When an email is delivered, Sendmachine replaces the macro with a real value.

Example:

<p>Hello [[FIRSTNAME]],</p>
<p>This email was sent to [[EMAIL_TO]]</p>
<a href="[[UNSUB_LINK]]">Unsubscribe</a>

Where macros can be used

Macros work everywhere in an email:

Location	Example
Email body	<p>Hello [[FIRSTNAME]]</p>
Email subject	Welcome [[FIRSTNAME]]
Links	<a href="[[UNSUB_LINK]]">Unsubscribe</a>
SMTP headers	X-SM-Campaign: My newsletter
Transactional emails	SMTP or HTTP API
