How do I get a free sending mailbox?
You already have one. Every new Warmerly account gets a free mailbox, created for you at signup and already warming up. You will find it under Accounts with a Free gift badge. It costs nothing, does not use a mailbox slot on your plan, and needs no domain or DNS setup, because it lives on a domain Warmerly owns.
What the free mailbox can do
- Warmup: always on. It started by itself at signup, and you cannot switch it off.
- Cold email: up to 10 a day, once it unlocks. It unlocks automatically after 7 days of warmup, as long as you have verified your email address. You get an email when it can send.
- One per person. Each user gets one free mailbox, ever.
You do not have to wait for the unlock to set things up. Build and launch a campaign on it today, and it starts sending by itself the moment the mailbox is ready.
Steps to use it
- Verify your email address, if you have not already.
- Open Accounts and click the mailbox with the Free gift badge. The panel "This one's on us" shows whether cold email is still unlocking or already on.
- Click Build a campaign with it, or create one from Campaigns > New campaign. See How do I launch my first campaign?
- Launch. Until the mailbox unlocks, the campaign waits, then sends up to 10 emails a day.
How long can I keep it?
As long as you are using Warmerly. It is only closed after 60 days with no activity from you, and you get two reminder emails first with a Keep my mailbox button. Signing in resets the clock. Once you connect your own mailbox or buy a OneMail mailbox, there is no countdown at all.
Need more volume? Get a hosted OneMail mailbox
Ten emails a day is a starting point. For real volume, connect your own mailbox (Connecting a mailbox) or let Warmerly host one for you with OneMail:
- Go to Accounts and click Add.
- Choose OneMail mailbox (we host it). Warmerly sets up the domain and DNS for you.
- Pick a route: Get a ready-warmed mailbox (already has 21+ days of warmup, when available), Add mailboxes to a domain you already have, Buy a new domain, or Connect a domain I own.
OneMail is billed per mailbox per month, and the price drops on bigger plans:
| Your plan | Price per OneMail mailbox |
|---|---|
| Free or Starter | $2.99/mo |
| Growth | $1.99/mo |
| Agency | $0.99/mo |
OneMail mailboxes never use your plan's mailbox limit. Ready-warmed mailboxes cost the same as any other OneMail mailbox. You can buy OneMail on the Free plan too; a card is needed.
Common problems
Cold email is still unlocking after 7 days. Check that your own email address is verified. The unlock also waits if the shared domain's latest blocklist check is not clean, or if the domain already has its share of unlocked free mailboxes.
Can I raise the 10 a day limit? No. Neither you nor support can change it. Connect your own mailbox or add a OneMail mailbox for more.
Can I pause warmup on it? No. Warmup is always on for the free mailbox.
Do I need a password for it? No. You are never asked for credentials. If it ever shows Reconnect, clicking it makes Warmerly issue a new mail password itself.
