The Email List Is the Only Thing You Keep

Run a giveaway and you will be offered a lot of metrics to feel good about. Codes claimed. Downloads on the day. A brief bump in your category.

Six months later, every one of those is gone. The downloads are indistinguishable from any other download. The chart position reset within a week. The people who claimed a code are unreachable — you have no idea who they were.

Except for one thing, if you set it up: the addresses.

Why this is the asset

An email list is the only channel in your marketing that nobody else controls.

Apple can change how the App Store ranks apps. Reddit can change how it treats self-promotion. An algorithm change can wipe out a channel that worked for two years, and nobody will email you first. Your list keeps working through all of it, because the connection is direct.

The concrete version: when you ship v2, or a second app, you can either start from nothing and hope, or you can send one email to the 500 people who already wanted the first one. Those 500 will convert at a rate no cold channel comes close to, because they are pre-qualified by an action — they typed out their address to get something from you specifically.

The exchange that makes it work

A promo code is currency. Do not leave it on the sidewalk.

• What most people do: post codes publicly → codes vanish in seconds → no idea who took them
• What works: claim page asks for an email → person gets a code → you have a reachable relationship

The second version costs the user about four seconds. That is the entire friction, and it converts most people who genuinely want the app.

The part almost everyone misses

Here is the mechanic that matters more than the giveaway itself: what happens after the codes run out.

A hundred codes go in maybe an hour if your post lands. Everyone who arrives after that hits a dead page and leaves. That is the majority of your traffic — the tail after the spike — and by default you get nothing from it.

If the page converts to an email capture instead, those people are worth more than the ones who got a code, not less:

• They wanted it enough to show up and be disappointed
• They have not been given a free copy, so they are a plausible future customer rather than a satisfied non-buyer
• They are an obvious "you missed out — here's early access to the next one" audience

This is the single highest-leverage setting in a giveaway, and it is off in most homemade solutions because a Google Form has no concept of running out.

What to actually do with the list

A list you never email is a list that will mark you as spam the day you finally do. Two rules:

Send something within a week. Not a pitch. Ask a specific question — "what is the first thing you'd change?" — because specific questions get answered and "any feedback?" does not. You will get your best bug reports this way.

Then send when you have news, and only then. A launch, a real feature, a price change. Three emails a year that people are pleased to receive beats a monthly newsletter nobody opens.

What the list is not for

It is not a review-generation channel. People who installed with a promo code cannot rate or review your app — Apple blocks it — and trading anything for a review breaks the guidelines regardless of platform.

Treat the list as what it is: a direct line to people who have already raised their hand. That is worth more than a review, and it does not expire.

Promo Code Queue captures the email with every claim and automatically converts your page to a waitlist when the codes run out, so the people who arrive late end up on your list instead of on a dead link.
