Turning 65 Direct Mail: A Sequence That Meets New Medicare Enrollees at the Right Time
How Medicare agents can build a turning-65 (T65) direct mail sequence around the 7-month Initial Enrollment Period, the Medigap open enrollment window, and CMS contact rules.
By the Mailbox Engine team · · 3 min read
Key takeaways
- A record 4.18 million Americans turned 65 in 2025, about 11,400 a day, and more than 4.1 million a year continue to age in.
- The Initial Enrollment Period lasts 7 months: 3 months before the 65th-birthday month, the month itself, and 3 months after.
- Missing Part B enrollment can mean a 10% penalty for each year someone could have signed up, so timely education is genuinely helpful.
- Start the sequence about six months before the birthday month and include a reply card or QR code to earn permission to call.
Every month, a new group of Americans reaches 65 and faces one of the more confusing financial decisions of their lives. They need clear information at the right time, and they're far more receptive to an agent who explains their options than to one who pushes a plan. A well-timed turning-65 sequence does exactly that.
The windows that matter
- Initial Enrollment Period. According to Medicare.gov, it lasts 7 months: starting 3 months before the month someone turns 65 and ending 3 months after.
- Automatic enrollment. Per CMS, people already receiving Social Security or Railroad Retirement benefits at least 4 months before turning 65 don't need to file an application for Part A and Part B.
- Late penalties. Medicare.gov explains that missing Part B enrollment, without a Special Enrollment Period, can add 10% for each year someone could have signed up.
- Medigap Open Enrollment. A 6-month window starting the first month someone has Part B and is 65 or older, during which insurers can't refuse to sell any Medigap policy they offer, per Medicare.gov.
Explaining these windows clearly is genuinely helpful, and it positions you as the expert before anyone else calls.
Why mail is the right channel
42 CFR 422.2264 permits unsolicited contact by mail and print media, while prohibiting unsolicited calls, texts, voicemails, door-knocking, and social media DMs. A turning-65 prospect is, by definition, someone who hasn't contacted you yet. Mail is how you start the conversation, and a reply card or QR code is how they invite your call.

Compliance checklist
- Follow CMS marketing content rules and submit materials for carrier review where required.
- Don't call unless the prospect requests contact or initiates it.
- Collect a scope of appointment before a personal marketing appointment. CMS removed the 48-hour waiting period for CY2027 marketing; the SOA itself is still required. See Medicare agent gift rules.
- Keep any promotional item to $15 or less and offer it regardless of enrollment.
Small postcards are free product on every Mailbox Engine plan; you pay postage. Turning-65 mailing lists are an additional cost. Scale the cohort size to your capacity, then compare plans on pricing.
Next steps
Choose your cohort size, write your six pieces, and get carrier approval where needed. Then connect the sequence to your AEP mail timeline and your client retention plan.

Frequently asked questions
When should I start mailing turning-65 prospects?
Many agents start four to six months before the 65th-birthday month, so the first pieces arrive before the Initial Enrollment Period opens three months before the birthday month.
Is it legal to send unsolicited mail to people turning 65?
Yes. 42 CFR 422.2264 permits unsolicited contact by conventional mail and other print media for Medicare Advantage marketing. Content must follow CMS marketing rules and carrier review requirements.
What is the Medigap Open Enrollment Period?
Under federal law, it's a 6-month window that starts the first month someone has Medicare Part B and is 65 or older. During that window, insurers can't refuse to sell any Medigap policy they offer.
How many pieces should a T65 sequence include?
Four to six pieces over about six to eight months is common, ending with a reply card or QR code invitation and a check-in after the birthday month.
