How to Write a Benefits Open Enrollment Reminder Employees Actually Act On

Every autumn, HR teams in the US send open enrollment emails, and every year a predictable share of employees miss the deadline, default into a plan they did not want, and then ask HR to fix it. Usually it cannot be fixed until next year, short of a qualifying life event.

The problem is rarely that people do not care about their benefits. It is that the email looks like every other HR email: long, full of plan names and acronyms, with the deadline buried in paragraph four.

Lead With The Deadline And The Action

The first two lines should answer: what do I need to do, and by when?

Before:

As we approach the end of the year, we are excited to share information about our 2027 benefits offerings. This year, we have partnered with our carriers to bring you enhanced options designed to support your health and wellbeing…

After:

Open enrollment for 2027 benefits closes on Friday 13 November at 17:00 ET. If you do nothing, your current medical, dental and vision elections roll over, but your FSA does not; you must re-enroll to keep it. It takes about 15 minutes in the benefits portal.

The second version tells people the deadline, the consequence of doing nothing, the one trap, and how long it takes.

Say What Changed

Employees mainly want to know: is anything different from last year?

• Premium changes, with the employee cost per pay period.
• New or removed plans.
• Changes to deductibles, networks or carriers.
• New benefits.

Put changes in a short list. Link to the full plan documents rather than pasting them.

Highlight The Common Traps

Every year has a few things people get wrong. Name them:

• Accounts that do not roll over, such as flexible spending accounts, which typically require a new election each year.
• Dependents who need to be added or removed.
• Life events and how they work outside open enrollment.

Make It Easy To Get Help

Give one place for questions, office hours or a short info session, and a contact. For employees choosing marketplace coverage for family members, HealthCare.gov explains marketplace enrollment periods.

A Reminder Sequence

One email is not enough. A simple sequence:

1. Launch (enrollment opens): what changed, deadline, how to enroll.
2. Midpoint: reminder plus the most common questions so far.
3. Three days before: short, deadline-focused.
4. Final day: one line, the deadline and the link.

Each one shorter than the last. See how to write a reminder email.

Accessibility And Clarity

Many employees read benefits emails on their phones, and some read English as a second language. Short sentences, plain words and descriptive links help everyone. Avoid unexplained acronyms; “HSA (health savings account)” the first time costs nothing.

A Context For HR Announcements

A Wrivio Context for benefits reminders could say:

Rewrite this as a short benefits reminder email for all employees. Plain, friendly and direct. Start with the deadline and what people must do, then what changed, then how to get help. Explain any acronym the first time. Keep every date, time, plan name, cost and rule exactly as written. Do not add benefits, changes or advice that is not in the original.

Press Ctrl+Shift+Space, paste the draft from your benefits team, and check every figure and date against the plan documents. A wrong premium in an enrollment email causes real problems. See how to write a policy change announcement for related writing.

Common Questions

How long should an open enrollment email be?

Short enough to read on a phone in under a minute, with links for detail. The first email can be slightly longer; reminders should be very short.

What subject line works for open enrollment?

Put the action and deadline in it, such as “Action needed: 2027 benefits enrollment closes 13 November”. See how to write an email subject line people actually open.

Should managers forward the reminder?

A short personal nudge from a manager often works better than another HR email, especially in teams that rarely read company-wide messages.

What if an employee misses the deadline?

Generally, changes outside open enrollment require a qualifying life event. Explain that clearly in your emails so employees understand the stakes before the deadline.
