1.- Your reputation as an email marketing campaign sender , that is, the history on the Internet linked to a specific domain or IP from which emails are sent. A domain can have a good, bad or no reputation with each ISP .
2.- An updated, segmented and clean list of records. For this reason, it is vital that you build your databases using permission marketing.
