03 / 05Why use it?

Fewer unnecessary emails
to keep.

Unnecessary emails accumulate. We keep everything because we fear deleting something important or do not have time to sort.

Storing them uses servers, energy and resources. TicTag provides a reference to make deletion easier and limit this accumulation.

  • Less unnecessary data to keep.
  • Easier sorting, less hesitation before deleting.
  • A simple digital sobriety habit.

Find emails that are no longer useful
and delete them in bulk.

  • Obsolete emails gathered in one search.

  • Fewer unnecessary emails stored for years.

One tag added once, thousands of emails easier to sort.

The problem

Our inboxes are digital landfills

360 billion emails are sent every day. Most become useless within hours but remain stored forever on servers consuming energy permanently.

We dare not delete

Fear of deleting an important email, lack of time, no clear reference to know what to keep. We either keep everything or delete everything.

Billions of emails stored for nothing

Dead data accumulating, more and more servers, energy and materials consumed continuously. An invisible but very real carbon footprint.

What if the email said when to delete it?

If the sender indicated the lifespan of their email via an easily detectable tag, everyone could massively delete single-use emails. That is exactly what TicTag offers.

The solution

What if the email itself indicated
when it becomes obsolete?

TicTag is a simple text to paste into your emails (the tags) to indicate their lifespan. Nothing to install, nothing to configure. It works in every inbox in the world.

1

The sender tags

They copy/paste a TicTag tag at the bottom of their email — TicTag1Y, TicTag3Y or TicTag5Y — to indicate its lifespan.
2

The recipient receives a dated email

They know at a glance that this email can be deleted in 1, 3 or 5 years. No more hesitation.
3

Sorting becomes simple and massive

Search "TicTag1Y", "TicTag3Y" or "TicTag5Y" in your inbox, filter by date, and delete everything at once.
Copy, paste, done
