Sprig functions

listmonk integrates the Sprig library that offers 100+ utility functions for working with strings, numbers, dates etc. that can be used in templating. Refer to the Sprig documentation for the full list of functions.

Example template

The expression {{ template "content" . }} should appear exactly once in every template denoting the spot where an e-mail's content is inserted. Here's a sample HTML e-mail that has a fixed header and footer that inserts the content in the middle.

<!DOCTYPE html>
      body {
        background: #eee;
        font-family: Arial, sans-serif;
        font-size: 6px;
        color: #111;
      header {
        border-bottom: 1px solid #ddd;
        padding-bottom: 30px;
        margin-bottom: 30px;
      .container {
        background: #fff;
        width: 450px;
        margin: 0 auto;
        padding: 30px;
    <section class="container">
        <!-- This will appear in the header of all e-mails.
             The subscriber's name will be automatically inserted here. //-->
        Hi {{ .Subscriber.FirstName }}!

      <!-- This is where the e-mail body will be inserted //-->
      <div class="content">
        {{ template "content" . }}

        Copyright 2019. All rights Reserved.

      <!-- The tracking pixel will be inserted here //-->
      {{ TrackView }}


For use with plaintext campaigns, create a template with no HTML content and just the placeholder {{ template "content" . }}

Example campaign body

Campaign bodies can be composed using the built-in WYSIWYG editor or as raw HTML documents. Assuming that the subscriber has a set of attributes defined, this example shows how to render those values in a campaign.

Hey, did you notice how the template showed your first name?
Your last name is {{.Subscriber.LastName }}.

You have done {{ .Subscriber.Attribs.projects }} projects.

{{ if eq .Subscriber.Attribs.city "Bengaluru" }}
  You live in Bangalore!
{{ else }}
  Where do you live?
{{ end }}

Here is a link for you to click that will be tracked.
<a href="{{ TrackLink "https://google.com" }}">Google</a>

The above example uses an if condition to show one of two messages depending on the value of a subscriber attribute. Many such dynamic expressions are possible with Go templating expressions.

System templates

System templates are used for rendering public user facing pages such as the subscription management page, and in automatically generated system e-mails such as the opt-in confirmation e-mail. These are bundled into listmonk but can be customized by copying the static directory locally, and passing its path to listmonk with the ./listmonk --static-dir=your/custom/path flag.

Public pages

index.html Base template with the header and footer that all pages use.
home.html Landing page on the root domain with the login button.
message.html Generic success / failure message page.
optin.html Opt-in confirmation page.
subscription.html Subscription management page with options for data export and wipe.
subscription-form.html List selection and subscription form page.

To edit the appearance of the public pages using CSS and Javascript, head to Settings > Appearance > Public:


System e-mails

base.html Base template with the header and footer that all system generated e-mails use.
campaign-status.html E-mail notification that is sent to admins on campaign start, completion etc.
import-status.html E-mail notification that is sent to admins on finish of an import job.
subscriber-data.html E-mail that is sent to subscribers when they request a full dump of their private data.
subscriber-optin.html Automatic opt-in confirmation e-mail that is sent to an unconfirmed subscriber when they are added.
subscriber-optin-campaign.html E-mail content that's inserted into a campaign body when starting an opt-in campaign from the lists page.
default.tpl Default campaign template that is created in Campaigns -> Templates when listmonk is first installed. This is not used after that.


To turn system e-mail templates to plaintext, remove <!doctype html> from base.html and remove all HTML tags from the templates while retaining the Go templating code.
