Open enrollment is one of the most important communication moments of the year for HR teams. Employees are asked to make decisions about health insurance, retirement contributions, voluntary benefits, dependent coverage, and more—often while juggling busy work schedules. A clear, timely, and well-structured email campaign can turn a confusing process into a confident decision-making experience.
TLDR: A strong open enrollment email template should clearly explain what employees need to do, by when, and where to get help. For example, a company with 500 employees might send a kickoff email, two reminder emails, and a final deadline notice, reducing last-minute questions by 30% compared with a single announcement. Use short subject lines, visible deadlines, benefit highlights, and direct links to enrollment resources. The best emails feel helpful—not like paperwork.
Why Open Enrollment Emails Matter
Open enrollment is not just an administrative task. For employees, it affects healthcare access, financial planning, family coverage, and peace of mind. Yet benefits information can quickly become overwhelming if it arrives as a dense PDF or a single long email packed with links.
That is why an effective open enrollment email strategy should do three things: inform, guide, and motivate action. Employees need to understand what is changing, what their options are, and what steps they need to complete before the deadline.
What to Include in an Open Enrollment Email
Before writing your template, make sure your email includes the essential details employees will look for first. These are the building blocks of a helpful message:
- Enrollment dates: Include the start and end date in a prominent location.
- Action required: Tell employees whether they must actively enroll or if current benefits will roll over.
- Benefit changes: Highlight major updates such as premium changes, new plans, or expanded coverage.
- Enrollment link: Make the platform or portal easy to find.
- Support options: Include HR contact details, office hours, webinars, or benefits guides.
- Deadline reminder: Make it clear that late enrollment may not be possible unless there is a qualifying life event.
Open Enrollment Email Template 1: Initial Announcement
The first email should introduce the open enrollment period and set expectations. Keep it friendly, organized, and action-oriented.
Subject line: Open Enrollment Starts Soon: Review Your Benefits Options
Hello Team,
Open enrollment for the upcoming benefits year will begin on [Start Date] and end on [End Date]. This is your annual opportunity to review your current benefits, compare available plans, and make changes for the year ahead.
During this period, you can:
- Enroll in or update medical, dental, and vision coverage
- Add or remove dependents
- Review voluntary benefits such as life insurance or disability coverage
- Update contributions to eligible spending accounts
Please visit [Enrollment Portal Link] to review your options. We encourage everyone to complete enrollment early to avoid last-minute issues.
If you have questions, HR will host a benefits overview session on [Date and Time]. You can also contact us at [HR Email].
Thank you,
Human Resources
Open Enrollment Email Template 2: Benefits Changes Highlight
If there are plan updates, premium adjustments, or new perks, send a separate email focused only on changes. Employees are more likely to absorb updates when they are not buried in a long general announcement.
Subject line: What’s New in This Year’s Benefits Package
Hello,
As you prepare for open enrollment, we want to highlight several important updates to this year’s benefits offerings.
- Medical plan update: [Briefly explain change, such as new carrier, deductible adjustment, or plan option]
- Expanded wellness support: [Mention mental health, fitness, telehealth, or wellness incentives]
- New voluntary benefit: [Describe any added benefit, such as pet insurance or legal assistance]
- Premium changes: [Summarize any employee contribution changes]
We recommend reviewing the full benefits guide before making your selections. You can access it here: [Benefits Guide Link].
Tip: Even if you plan to keep your current coverage, take a few minutes to confirm your dependents, beneficiaries, and contribution elections.
Best,
Human Resources
Open Enrollment Email Template 3: Reminder Before the Deadline
Reminder emails are essential because employees often intend to enroll but postpone the task. A good reminder should be brief, urgent, and easy to act on.
Subject line: Reminder: Open Enrollment Ends on [End Date]
Hello Team,
This is a reminder that open enrollment closes on [End Date]. If you have not yet completed your benefits elections, please log in to [Enrollment Portal Link] as soon as possible.
After the deadline, you may not be able to make changes until the next open enrollment period unless you experience a qualifying life event, such as marriage, birth or adoption of a child, or loss of other coverage.
Need help? HR will be available for questions during the following times:
- [Date and Time]
- [Date and Time]
- [HR Contact Information]
Please complete your enrollment by the deadline to ensure your coverage is in place for the new plan year.
Thank you,
Human Resources
Open Enrollment Email Template 4: Final Day Notice
The final day email should be direct. Employees scanning their inbox need to immediately understand that action is required today.
Subject line: Final Day to Enroll: Benefits Deadline Is Today
Hello,
Today is the last day to complete your open enrollment elections. The enrollment window closes at [Time and Time Zone].
If you still need to review or update your benefits, please go to [Enrollment Portal Link] now.
Before submitting, confirm that your:
- Medical, dental, and vision elections are correct
- Dependents are listed accurately
- Beneficiaries are up to date
- Spending account contributions are correct
If you need immediate assistance, contact [HR Contact].
Thank you,
Human Resources
Best Practices for Employee Benefits Communications
A template is only effective if it is part of a thoughtful communication plan. Employees may miss a single email, misunderstand a technical term, or delay action because they are unsure what to choose. To improve engagement, consider these best practices:
- Use a campaign format. Send multiple short emails rather than one long announcement. A typical sequence might include a launch email, benefits changes email, educational reminder, deadline reminder, and final day notice.
- Write for real people. Replace jargon with plain language. Instead of “passive enrollment,” say “your current elections will automatically continue unless you make changes.”
- Make the deadline impossible to miss. Put the date in the subject line, opening paragraph, and closing reminder.
- Segment when possible. New hires, remote employees, employees with dependents, and part-time workers may need different information.
- Offer multiple ways to learn. Pair emails with FAQs, short videos, live Q&A sessions, and downloadable guides.
Subject Line Ideas for Open Enrollment Emails
Subject lines can determine whether employees open the message promptly or ignore it until later. Keep them clear and specific:
- Open Enrollment Begins [Date]: Review Your Benefits
- Your Benefits Options for [Year] Are Now Available
- Important: Benefits Enrollment Deadline Is [Date]
- Action Required: Confirm Your Benefits Elections
- New Benefits Updates You Should Review
- Final Reminder: Enroll by [Time] Today
Common Mistakes to Avoid
Even well-intentioned benefits communications can create confusion. Avoid sending emails that are too long, too vague, or too late. Do not assume employees know what terms like deductible, coinsurance, HSA, FSA, or qualifying life event mean. Also, avoid hiding the enrollment link behind multiple clicks. The easier the process feels, the more likely employees are to complete it on time.
Another common mistake is focusing only on compliance and forgetting the employee experience. Benefits are personal. A parent comparing family medical plans, a young employee choosing coverage for the first time, and a caregiver reviewing dependent options may all read the same email with very different priorities. Good communication acknowledges that employees are making meaningful decisions, not just checking a box.
Final Thoughts
An effective open enrollment email template is clear, timely, and empathetic. It gives employees the information they need without overwhelming them, and it creates a simple path from awareness to action. By using a structured email sequence, highlighting key changes, and repeating deadlines, HR teams can increase participation and reduce confusion.
Most importantly, benefits communication should feel supportive. When employees understand their options, know where to ask questions, and have enough time to decide, open enrollment becomes less stressful for everyone involved.
