Notice: Change in [Policy/Procedure] Starting [Date]
This is your go-to when the news isn’t thrilling, but skipping it might cause real confusion.
Simple structure, timestamped, and unmistakable in purpose.
The “[Policy/Procedure]” phrasing gives it versatility: use it for time-off requests, expense reimbursement, or onboarding protocols.
Reminder: [Event/Deadline] Is This Week
This one works because people forget. Honestly, most of us do. I’ve used it to follow up on mandatory compliance training, quarterly reviews, or payroll updates.
The phrase “this week” creates a sense of urgency without sounding panicky. It lets the recipient know that time is running out, but there’s still time.
Reminder emails with this kind of subject line tend to have open rates 25-35% higher than vague nudges like “Just checking in.”
Urgent: [Situation] Requires Your Attention Today
No ambiguity, no fluff. I usually recommend this subject line for time-sensitive updates, such as system outages, benefit enrollment deadlines, and client fire drills.
Note: If you’re sending this to customers, be extra careful. Overuse can trigger panic or loss of trust.
Upcoming [Event/Change]: What You Need to Know
This is the perfect subject line for when you need to inform people of something important, but it’s not an emergency.
This subject line can also be:
- Here’s What’s Changing on [Date]
- [Event/Change] Is Coming: Be Ready
- Heads-Up: [Important Detail]
We Noticed Something, Thought You Should Know
This one’s personal. A little cheeky, but it works. Use this line to highlight things like suspicious logins, inactive accounts, or sudden spikes in usage.
Where it shines: In customer service and account success roles. You’re reaching out proactively, but in a non-alarmist way.
This subject line can also be:
- Noticed This on Your Account—Heads-Up
- We Flagged Something Unusual. Want to Check?
- Your [Feature/Usage] Spiked. Here’s Why
