Tone: optimistic
People plan fresh starts in January. Combine that desire with messaging about how our products have evolved, and offer a sweet upsell as well.
Gratitude emails always work, but this one’s more human than most. It’s warm and personalized without sounding robotic.
This kind of subject line isn’t about clicks—it’s about connection. It performs best when paired with a heartfelt message inside the email, not a sales push.
Tip: don’t rush it. Send this toward the very end of December or early January to reflect on the full calendar year. And keep the tone gentle and sincere. Your audience can feel the difference.
This line builds anticipation for what comes after the new year. It’s forward looking, so it fits B2B newsletters, product roadmaps, or service updates.
