E-mail retargeting can refer to either:
Contents
Display-Ad Based
Email from the advertiser is sent to recipients with a tracking pixel that tags the recipient's browser, in the same way they would be tagged if visiting a webpage.
Email retargeting is only effective if the email is opened in a web browser, where the tracking pixel will function. Any recipient who uses a dedicated mail client will not be tagged. Additionally, Gmail's decision to cache images means that this method of advertising does not work with gmail addresses.
Email Based
E-mail retargeting relies on sending personalized e-mail to an anonymous website visitor. It is possible thanks to DMP (Data Management Platform) where cookies collected on a website include the IP address of the visitor (the IP address can be read from the visitors web browser's header information). The IP address is then matched against the IP addresses previously collected with form submissions that include an e-mail address.
- Visitor browses a website, views a product and leaves
- Cookies from the website matches the user to an email address
- Visitor receives a personalized offer via e-mail message concerning the product they viewed
This form of remarketing helps increasing conversion by reaching interested audience only.
