I have all of my contacts loaded into Google Contacts but the problem is, I’m never convinced that they are up to date or even sure if I should still have the person’s contact details listed.
To address this I created the following script which will send me an email every day with a randomly selected contact.
I can then review the contact’s details, compare it with LinkedIn, Facebook and Twitter and then either update their contact details or send them an e-mail to catch up with them.
