"Welcome to LAFD's free Smoke Alarm Test reminder. We send only one message a month reminding you to test your smoke alarms. That's all!"
What can you do? Set up a Twitter account to remind folks to back-up digital pictures, hard drives, MP3's; to run anti-virus updates and malware scans; run service packs and O/S upgrades.
I set up a Twitter account at fixyourpc to help you do that. Have your customers follow the updates out of goodwill. It's also a chance for you to upsell and cross-sell external hard drives, flash drives, media, and services and maintenance contracts.
Let me know if you want to work with me on this "Alarm system". All part of the marketing package being revealed in mid-January!
