Another great way for marketers to promote their email list is through their customer support team. It can be done via different customer support channels: social media, telephone, chat, emails… Your customer support team can be a great asset to enrich your contact list as support is one of the main client touchpoints.

For example, if someone contacts your company to ask if one of your products will be coming back into stock, reply and also encourage them to sign up to your email database so they can be the first one to see the new catalogue or learn about next season’s products or services.
Promoting your email newsletter via support channels cannot be done randomly. There are certain rules that need to be followed in order to do this right:
Store consent by keeping a record of how you obtained the express consent of each new subscriber. That includes: the data subject who gave the consent, when the consent was obtained, and the specific purpose for which the consent was given. This is mandatory under the General Data Protection Regulation (GDPR).

Leveraging your support team, who is one major customer touchpoint, will help you promote your newsletter and get more subscribers out of your clients.
