Using query string in campaign emails lets you pass information from one page to another via URLs. A query string is the part of a URL that comes after the question mark (?).
To understand query strings, let’s first take a closer look at a sample URL that uses one:
https://example.com/product/shirt/?utm_source=newsletter&utm_medium=email&utm_campaign=winterThe first section of a URL is called a protocol (https). It is followed by the domain name of the website, or the hostname (here https://example.com ). And the next part (after the forward slash) is the path (product/shirt/?).
Everything that follows the path after the question mark (?) is the tail of the URL, also known as the query string (utm_source=newsletter&utm_medium=email&utm_campaign=winter).
MailBluster has the option to put a query string in your campaign email, which you will find under Campaigns > Content > Query String section:
If you set query string in your campaign like this:
utm_source=email&utm_medium=MailBluster&utm_campaign=campaign_xyzthen it will be appended to all the links of the campaign. Using query strings helps track campaigns and user interactions effectively.
