A tickler file is presented as a key tool for organization in David Allen’s book Getting things Done. I’m searching for an electronic version of this system. And so far I didn’t find anything that give full satisfaction. The 2 tools I found are email notification in the future:

• iTickleMe: Email Follow-Up Reminders. Here how it works:

1. Register your email addresses with iTickleMe Email Follow-Up Reminder Service

2. Create an email to anyone, or even to yourself

3. Now here’s the trick:

If you want the email to return to you in 1 day:
Send or Copy it to 1d@poingo.com

If you want the email to return to you in 2 weeks:
Send or Copy it to2w@poingo.com

If you want the email to return to you in 3 months:
Send or Copy it to 3m@poingo.com

• GMail – GTD Tickler: Adds ‘Tickle me’ link for each message in message view. And of course it’s dedicated to gmail.

I will provide some feedback once I will use those tools for some time.
