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.
Keep the subject line and pre-header short: The subject line is crucial. Keep it short so the reader knows exactly what the email topic is about. And the pre-header text (also known as snippet text), don’t let it go to waste by using “To view this email in your browser…”. Instead, summarize the email or include a call to action (i.e., Use “FREESHIP” to get free shipping).
Dynamic segmentation – As alluded to earlier, you can’t just send out a generic message to everyone on your list. While basic demographic data can be used to segment your list, that’s far from taking the dynamic approach. Automation tools can help you segment your list as they go through the funnel, allowing you to send personalized messaging depending on their actions and behaviors.
