# Resurface old links

> A Resurfacer channel sends links drawn at random from everything in its sources, however long ago they were added, at the days and times you choose.

A Resurfacer channel sends links drawn at random from everything in its sources, however long ago they were added, at the days and times you choose.

## How is Resurfacer different from Delta?

Delta sends only what's new since its last delivery, while Resurfacer can send links you saved years ago.

## How do I set up a Resurfacer channel?

**1. Open the cadence**

Make a new channel with **N**, then **D**, or choose **Edit channel** on an existing channel's card on **Channels**. Under **Cadence**, choose **Resurfacer**.

**2. Choose how many links**

Set **Links per delivery**, from 1 to 20. It starts at 1.

**3. Choose repetition**

**Exhaust**, the default, sends every link once before any repeats. **Allowed** draws from all links every time.

**4. Choose when**

Select the days, then a time for each day in 24-hour form. **Add time** adds another time to a day. Set **Every N weeks** from 1 to 12.

**5. Give it sources and an endpoint**

Subscribe it to curations from their **Subscribe** buttons, include Following if you like, and choose where it sends.

The channel's card then reads, for example, "Resurfacer · 3 links · Exhaust".

## Will a Resurfacer repeat links?

Never within one delivery. With **Exhaust**, you get every link once before any comes back. With **Allowed**, each delivery draws on its own, so a link can return the next time. A link that's in several of the channel's curations counts once.

## What counts as sent?

A link counts as sent once its delivery is sent. It doesn't count if the delivery was **Not sent**, **Refused by receiver**, **Cancelled**, or **Withheld**, so with Exhaust it stays in the draw.

## What if my sources have fewer links than I asked for?

You get all of them. With Exhaust, when fewer unsent links remain than the number you chose, you get the rest, topped up from a fresh round. If the sources are empty at a scheduled time, an email, text, or phone channel records a **Cancelled** delivery and sends nothing.

## Does changing the settings start over?

Switching a channel to Resurfacer, or from Allowed to Exhaust, does. Either one starts a fresh round: every link is unsent again.

## Can I resurface links from the curators I follow?

Yes. With Following as a source, a Resurfacer draws from every public curation of the curators you follow, including links they added long ago.

## What does a Resurfacer delivery look like?

* **Email:** one email per scheduled time, like any delivery.
* **Text message:** a single link is sent in the text; several are sent as a link to the delivery page.
* **Phone call:** Delivia talks through the picks, and doesn't call them new.
* **Webhook or Agent:** one delivery with every pick.

## Does it follow my timezone?

Yes, the one in **Settings**. Changing it moves every channel's schedule.
