Notification contents such as message body, title and link can be personalized. They can be substituted with tag values for each user. Read more about tagging:
Example message titleHello {{name}}
Example message bodyWe have promotion for {{last_visit_product}}
Example message urlyour_shop.p?product_id={{last_visit_product_id}}
Example message title with default valueHello {{name|default('subscriber!')}}
Example message body with default valueWe have promotion for {{last_visit_product|default('t shirts')}}
Example message url with default valueyour_shop.pl?product_id={{last_visit_product_id|default(99)}}
It is obvious that not everyone will include tags. In this case, the campaign can be prepared only for subscribers who contain the tag.
