Mailster offers five handy shortcodes for easy newsletter integration. Use [newsletter] to embed campaigns, [newsletter_list] for recent newsletters, and [mailster_form] for sign-up forms. You can also check subscriber counts with [newsletter_subscribers]. Note that some codes, like [newsletter_signup_form] and [newsletter_button], are now deprecated.
If you’re using Visual Composer in WordPress and encountering shortcode issues with Mailster, you can remove them by adding custom snippets to your theme’s functions.php. This ensures that the content remains intact while filtering out undesired shortcodes. Adjust the snippets accordingly for custom post types or other page builders.
Shortcodes are disabled by default in Mailster to prevent HTML injection that could disrupt emails. Users can enable them in advanced settings, but all registered shortcodes will be removed from the final email. To add custom shortcodes, use the appropriate filter function in the code.
