How to redeem your AppSumo code

Bought WarmySender on AppSumo? Redeeming your code activates your lifetime plan in under a minute. Open WarmySender from your AppSumo account, click Activate, sign in with Google, Apple, or a one-time email code, and your plan unlocks on the spot — there's no password to create and nothing to set up first.

WarmySender is a 4-pillar outreach platform — Cold Emailing, Email Warmup, LinkedIn Outreach, and Multichannel sequences — plus a built-in B2B leads database and real-time email verification. Your AppSumo plan covers cold email and warmup and more, and this guide walks you through redeeming your code and getting in.

Redeem your code in four steps

The whole thing takes under a minute, and there's nothing to prepare before you start:

1. Open WarmySender in your AppSumo account. Sign in to AppSumo, go to your Products, find WarmySender, and click Activate (some deals label the button Redeem). This carries your code across for you — you never have to copy, paste, or type it anywhere.
2. Sign in to WarmySender. You'll land on a short activation screen. Choose how you'd like to sign in — Continue with Google, Continue with Apple, or Sign in with email code (we email you a one-time 6-digit code). There's no password to create and nothing to remember.
3. Your lifetime plan unlocks instantly. The moment you're signed in, your plan is live. Your tier's warmed and cold mailboxes, your monthly sending allowance, your leads, and your email verifications are all ready to use right away.
4. Get going with the 60-second tour. First time in? Take the quick product tour, then connect your first mailbox and switch on warmup. That's you set up.

That really is the whole process: open from AppSumo, sign in, done. If the activation screen ever tells you your deal is still being confirmed, give it a minute and reopen the activation link from AppSumo — that final confirmation clears on its own and your plan activates.

Already have a WarmySender account?

No problem — you don't need to start over or create a second account. When you open the activation link, simply sign in with your existing WarmySender account (the same Google, Apple, or email you already use). Your AppSumo code links to that account, and your lifetime plan takes over from whatever you were on before. Everything you already have — your mailboxes, campaigns, warmup history, and prospects — stays exactly where it is.

One code links to one account. If you happen to sign in with an account that already has this code, WarmySender just confirms it's active — going through activation a second time never doubles anything up or causes a problem.

Upgrading or changing your tier

Your tier is managed entirely on AppSumo. If you move up or down a tier — or add another code — do it from your AppSumo account, and your WarmySender plan updates automatically to match. There's nothing to re-activate on our side and no waiting around: change it on AppSumo, and your new limits show up in your account.

This works both ways. Move up and your higher allowances apply; move down and your account settles onto the smaller tier. Either way, WarmySender simply follows what your AppSumo plan says — you never have to tell us about the change.

What your plan includes

Your AppSumo lifetime plan is a full WarmySender plan, not a stripped-down version. Depending on your tier, you get:

• Email warmup on a set of mailboxes, quietly building and protecting your sender reputation so your emails land in the inbox instead of spam.
• Cold email campaigns across your connected mailboxes, with multi-step sequences that send gradually and stop the moment someone replies.
• A monthly sending allowance for your campaigns.
• A built-in B2B leads database with a monthly allowance, so you can find new prospects without leaving the app.
• Email verification with a monthly allowance, to clean your lists before you send and keep bounces low.

Higher tiers include more mailboxes, more monthly sending, more leads, and more verifications, plus room for additional workspaces and teammates. Your exact numbers are set by the tier you bought on AppSumo, and you can always see them in your account.

Frequently asked questions

Do I need a password?

No. WarmySender doesn't use passwords at all. You sign in with Google, Apple, or a one-time 6-digit code we email you — whichever you prefer on the activation screen. There's nothing to create and nothing to remember, and the next time you sign in you simply use the same method again.

I already use WarmySender — can I add my code?

Yes. Open the activation link and sign in with your existing WarmySender account. Your AppSumo code links to that account and your lifetime plan takes over, while all your mailboxes, campaigns, warmup history, and prospects stay exactly as they are. There's no need to create a second account, and nothing you've already set up is lost.

How do I upgrade or downgrade my tier?

You change your tier on AppSumo, and your WarmySender account updates automatically to match. Move up for higher allowances or down to a smaller tier from your AppSumo account — there's nothing to re-activate on our side, and your new limits are reflected in your account without any extra steps from you.

Which email should I use?

Any email you like — you're not tied to the one you used on AppSumo. Sign in with the email (or the Google or Apple account) you want your WarmySender account to live under, and your code links to that account. If you already have a WarmySender account, sign in with that one so everything stays together in a single place.

What happens if I request a refund on AppSumo?

Your WarmySender access ends once the refund is processed. While your AppSumo purchase is active your plan stays active; if you refund it through AppSumo, your lifetime plan is removed once that refund goes through. Up until then nothing changes, and your account isn't touched in the meantime.

Do I get LinkedIn and Instagram outreach?

LinkedIn and Instagram outreach are optional paid add-ons you can add anytime from inside WarmySender — they aren't part of the AppSumo plan itself. Your AppSumo plan covers cold email, email warmup, the leads database, and email verification. If you'd like to add LinkedIn or Instagram later, you can do it right in the app whenever you're ready.
