With the GDPR now governing all email correspondence across Europe, adding an opt-out option to your email template no longer cuts it. Under this act, you must have explicit consent from your contacts to send them emails. Explicit, in this case, means the checkbox a person must click to opt in to an email subscription isn't pre-checked when they see it on your website. And when you buy your email lists, the people on it haven't been given this option -- making you non-compliant with GDPR before you send your first email.
Win-back: An existing customer is soon approaching the end of his yearly subscription. The customer hasn’t used your product in 3 months and you need a way to win them back and keep them for another year. Create a “win back” email that sends an automated email to all customers that are coming to end of their contract with a list of new product features and a short plan on expected releases in the next six months.
Ask for the right information upfront: Great personalization starts way before you hit the ‘send’ button. It all starts with your sign up form. Without data such as name, company and location, you will be very limited with your personalized communication. Remember to only ask for the information you need, rather than the information you want. This is one of the ways that GDPR has impacted marketing teams.
