Keeping them on an email list with regular messages is a good way to keep your name in front of them without being a nuisance. They will be surprised and delighted when you call to wish them a happy birthday.

Asking if there is anything you can do for the buyers after 30 days.  Then once a year or so.  The way it works if they feel they got their money worth they will recommend you.   But if you push for a referral like many agents feel that pain.   

Average Americans move like once every 10 years now. My referral rate is lower over time.  Many referrals do not pan or give up..... Not a sure thing these days.

I do it at random times. Not just because of a holiday. Remind them about SEV values around March and offer to make copies of appraisal for tax tribunal if necessary. 

My crm keeps dripping stuff to them.

I typically will reach out to them several times a year with some type of observant card.

I send them holiday cards, I email, text I have a cool app that sends them info about their home.

I give 100% before and during and when we close, I shut it off. If they need me, they can call me. Who else would they call? Once me, always me

Paul,

Know what your buyers expect by asking them.  Be helpful to them, find out what they need: a new vet?  let them know of a new restaurant, etc.  A

Holiday cards/emails, occasional emails with news about the neighborhood market or other useful items, and a personal call now and then. Frequency varies by the relationship.

I send a monthly newsletter, Christmas or other religeous cards, birthday, anniversary and so a husband is forwarned the anniversary and her birthday a week early.

I have it set up in my CRM to sent a useful email once and awhile, sent out a card 1 year after closing, a phone call from time to time. 

Client's birthdays and anniversaries of their closing. 

Monthly Newsletter and mailout about 4 times per year.  Occasional call should something trigger it.

Paul S. Henderson, Realtor, Tacoma Washington I send them monthly item of value (the drip campaign) and call them at regular interval and ask about how is everything.
