Every autumn, we send out the annual open enrollment email—only to face a flood of last-minute questions on the final afternoon of the enrollment window. Many employees ignore these messages entirely until the deadline is hours away. Managing this communication gap requires a shift from dense policy summaries to clear, structured, and timely updates.
Why open enrollment emails get ignored
Most benefits emails go unread because they overwhelm the reader. When an employee opens an email and sees a wall of text filled with insurance jargon, deductibles, and co-insurance percentages, they close the tab to read it later. Usually, "later" never comes.
To get employees to take action, you must shift from dense policy language to clear, action-oriented messaging. Employees do not need to understand every backend operational detail of your health insurance carrier in the first email. They need to know what is changing, what actions they must take, and when they must complete those actions.
Keep your messages short, focused, and centered on what the employee needs to do next. If you reduce the cognitive load of the email, your team is far more likely to read it and act on time.
The ideal open enrollment communication timeline
A single email sent on the day enrollment opens is rarely enough to get your team to take action. Busy employees need multiple touchpoints to absorb the information, discuss options with their families, and make their decisions. A structured cadence of four to five touchpoints prevents last-minute panics and missed deadlines.
Here is a practical timeline to structure your communications:
Three weeks before enrollment: The heads-up email
Send a brief heads-up message to prepare your team. Let them know the dates of the upcoming open enrollment period. This gives employees time to gather necessary personal documents—like social security numbers for dependents—before the system opens.
One week before enrollment: The preview
Send a summary of any major changes for the upcoming plan year. If premiums are changing or if you are switching carriers, share this information now. Early transparency builds trust and gives employees time to process changes before they have to make selections.
Day one: The official launch announcement
Send the official invitation to enroll. This email must include direct links to your enrollment portal, step-by-step instructions, and clear details on how to get help if they get stuck.
Mid-point: The weekly reminder
Send a gentle reminder halfway through the enrollment window. Highlight how many days are left and address common questions you have received during the first week.
Two days before the deadline: The final countdown
Send a final, urgent warning to those who have not yet submitted their selections. Clearly state that the window is closing and explain the consequences of missing the deadline.
How to structure your announcement email
Your official launch email should be easily scannable. Use bullet points and bold headers so busy employees can scan the email in under thirty seconds.
Every launch email should contain these five core elements:
- The deadline: Put the final date and time in bold at the very top of the message.
- What is changing: A high-level bulleted list of changes to premiums, plans, or carriers.
- The action steps: A numbered list showing exactly where to click and what to do.
- Where to find help: Contact details for HR or your benefits support team.
- The consequences: A clear statement explaining what happens if they do nothing.
A worked example of an enrollment email
Here is an example of how to structure this message for your team.
Subject: Action Required: Open enrollment is now open (Deadline: November 15)
Hi Team,
Our annual benefits open enrollment period is officially open. You have from today until Friday, November 15, at 5:00 PM EST to make your benefits selections for the upcoming year.
What is changing for this year (Example numbers only):
- Health plans: We are keeping our current health insurance provider, but premium contributions will increase by $5 per pay period for individual plans and $12 per pay period for family plans.
- Dental benefits: We have added a new dental plan option that covers adult orthodontia.
- Flexible Spending Accounts (FSAs): You must re-enroll in your FSA if you wish to contribute next year. Your current contribution level will not roll over automatically.
How to complete your enrollment:
- Log into your company benefits portal.
- Review your current selections and compare them against the new options.
- Confirm your dependents and beneficiaries.
- Click "Submit" to finalize your choices.
If you do not submit your selections by November 15 at 5:00 PM EST, your current medical and dental coverage will carry over to next year at the new premium rates, but you will lose your FSA contributions for the year.
If you have questions, we are hosting a virtual Q&A session this Thursday at 2:00 PM EST. You can also reply directly to this email with any personal questions.
Best regards,
The HR Team
Subject lines that get employees to open the email
The subject line of your email is your first—and sometimes only—chance to grab an employee's attention. Vague subject lines like "Benefits Information" or "Open Enrollment Update" are easy to ignore. Use clear, urgent subject lines that state the deadline to drive higher open rates.
Consider these examples of clear, action-oriented subject lines:
- Action Required: Open enrollment closes on [Date]
- [Action Required] Choose your benefits for next year by [Date]
- Open enrollment is live: Here is how to select your plans
- Only 48 hours left to submit your benefits choices
Avoid using all capital letters or excessive exclamation points. These can trigger spam filters or cause employees to tune out the message as background noise. Keep the tone professional, clear, and urgent.
Keeping compliance simple and clear
During open enrollment, you must distribute specific legal disclosures—such as Summary of Benefits and Coverage (SBC) documents and annual compliance notices. Trying to paste all of this legal language directly into your main email will overwhelm your employees and guarantee they stop reading.
Keep compliance documents as attachments or links rather than pasting them into the body of your main email. You can host these documents in your company's shared drive or attach them as PDFs to your launch message. This keeps your main email clean and focused on action steps while still meeting your distribution requirements. Because benefits regulations and local requirements vary, you should always consult your legal counsel to ensure your distribution methods meet all federal and state standards.

FAQs
How far in advance should I announce open enrollment?
It is best to send your first heads-up email about two to three weeks before the active enrollment period begins. This gives employees plenty of time to review their current plans, discuss options with their families, and prepare for any upcoming changes.
What should I do if employees miss the open enrollment deadline?
Generally, employees cannot make changes after the deadline unless they experience a qualifying life event—such as marriage or the birth of a child. Because plan rules and compliance regulations vary, you should consult your legal counsel or benefits broker to understand your options if an employee misses the window.
How can I make sure employees actually understand their benefits options?
Avoid using heavy industry jargon. Instead, focus on real-world scenarios—like how a deductible works in practice. Providing simple benefits enrollment guides and holding brief Q&A sessions can also help clarify complex plan details.
