# Can I launch a campaign before my mailbox has finished warming up?

> Yes. Build and launch on day one. A new mailbox starts low and climbs each sending day. The free mailbox is for replies, tests and one small first campaign.

Yes, you can build your sequence and launch on the day you sign up. You do not have to come back later. Warmerly keeps the early sending gentle for you.

What you get depends on which mailbox the campaign uses.

## If you use your free mailbox

Every account has one free mailbox that starts warming up at signup. It warms up and can be used for replies and tests. After 14 days of warmup it can also send a small first campaign, up to 3 emails a day, to verified addresses only. A campaign you launch before then waits and starts by itself when the mailbox is ready. To send at normal volume, connect your own mailbox (Google, Microsoft or SMTP) or add a hosted OneMail mailbox, which sends to verified addresses. See [How do I get a free sending mailbox?](https://warmerly.com/docs/help/free-sending-mailbox).

If the free mailbox is the only sender on a campaign and it cannot send yet, the launch check tells you why and names what to connect.

## If you use your own connected mailbox

A mailbox you have connected can be used in a campaign straight away. To keep a young mailbox safe, the campaign's **volume ramp** is switched on automatically when you create it if your project has no mailbox yet, or any mailbox has fewer than 14 days of warmup:

- **Day one: 3 emails per mailbox.**
- Then 1 more per sending day, up to 15 per mailbox per day (about the 13th sending day).
- Sending days only count, so weekends you do not send on do not advance it.

You can change or switch off the ramp under the campaign's **Settings > Advanced**. For a project where every mailbox is already established, the ramp starts off, so it does not hold a warm mailbox back. Details are in [Why does my campaign send fewer emails than my daily limit?](https://warmerly.com/docs/help/campaign-sending-schedule).

Keep **warmup switched on** while you send. It keeps running alongside your campaigns and is what builds the reputation that lets volume grow. See [How warmup works](https://warmerly.com/docs/how-warmup-works).

## What day one looks like

- The campaign is **live** from the moment you start it.
- Nothing is sent outside your sending days and hours.
- A new mailbox sends only a few emails a day at first, so the campaign will look slow. That is the ramp working, not a fault.

## What this does not do

- It does not make a brand-new domain safe to blast. The ramp limits day-one volume; it does not replace warmup or correct DNS. Check your mailbox's DKIM, SPF and DMARC. See the [guides](https://warmerly.com/docs/guides).
- It does not let the free mailbox send before its 14 days of warmup are done.
- It does not skip your plan's limits. See [Plans and limits](https://warmerly.com/docs/plans-and-limits).

## Common problems

**The launch check says the free mailbox cannot send campaigns yet.** The check names the reason: still warming up, an unverified email address, a recent bounce, or a full shared domain. To send now, connect your own mailbox or add a OneMail mailbox on **Accounts**, then try again.

**The launch check says something else.** Read the reason. Fix the mailbox on **Accounts**, then try again.

**Launched, but nothing has sent.** Check the date in **Launch readiness**, your sending days and hours, and the [troubleshooting checklist](https://warmerly.com/docs/troubleshooting#a-campaign-is-not-sending).
