# Email Warm-up Schedule Planner

A day-by-day ramp for a new inbox, from first sends to full cold-email volume.

Email Warm-up Schedule Planner Instant · free

## What is an email warm-up schedule?

An email warm-up schedule is a plan for gradually increasing how many emails a new inbox or domain sends each day, so mailbox providers learn to trust it before it carries full cold email volume. A brand-new inbox that suddenly sends hundreds of messages to strangers looks exactly like a spammer’s throwaway account. One that starts with a handful of genuine conversations and grows steadily looks like a real person joining a real company.

This free warm-up planner builds a day-by-day schedule from four inputs: emails on day one, your target cold emails per day, the daily increase and the age of the domain. It adds a warm-up-only period first (longer for newer domains), then ramps cold sends up to your target, with notes at the key points, and tells you the day you reach full volume.

## Key takeaways

- New domains need about two weeks of warm-up only before any cold email.
- Then ramp cold sends by a few emails a day to your target.
- Keep warm-up running alongside campaigns.
- Watch bounces, complaints and replies; hold volume if any slips.
- Make sure SPF, DKIM and DMARC pass before day one.

## How to use the warm-up planner

1. **Set emails on day 1**: the first day’s cold sends after the warm-up-only period. Five to ten is a common start.
2. **Set your target**: the cold emails per day you want each inbox to send at full volume.
3. **Set the daily increase.** One to three extra emails a day is a typical, cautious ramp.
4. **Choose the domain age.** New domains get the longest warm-up-only period.
5. **Press “Build schedule”** to see the full table.

## How the schedule is built

The plan has two phases:

1. **Warm-up only.** No cold emails. A warm-up tool exchanges messages with a network of real inboxes that open, reply and rescue your mail from spam, while you send a few genuine one-to-one emails yourself. The planner uses 14 days for domains under 30 days old, 7 days for domains one to six months old and 3 days for older domains.
2. **Ramp.** Cold emails start at your day-one number and increase by your daily step until they reach the target. Warm-up keeps running throughout and after.

These timings are a sensible, cautious default rather than a rule from any mailbox provider. If your metrics are healthy you can ramp a little faster; if anything slips, hold the volume.

## What to watch while you ramp

| Signal | Healthy | Action if not |
| --- | --- | --- |
| Bounce rate | Under 2% | Pause, clean the list with the [Email Verifier](https://prosyo.com/tools/email-verifier/), resume at the previous volume. |
| Spam complaints | As close to zero as possible | Review targeting and copy; reduce volume. |
| Replies | Arriving in the inbox, not spam | If replies stop entirely, test placement and check your domain. |
| Warm-up placement | Mostly inbox | If warm-up messages land in spam, hold volume and check authentication. |
| Authentication | SPF, DKIM, DMARC pass | Fix with the [Domain Health Checker](https://prosyo.com/tools/domain-health-checker/) before continuing. |

## Before day one: the setup checklist

- The domain has MX records and can receive email.
- SPF, DKIM and DMARC are published and passing.
- The domain’s website redirects to your main site or shows a real page.
- Each inbox has a real name, a profile photo and a simple signature.
- The domain is not on any blocklist; check with the [Blacklist Checker](https://prosyo.com/tools/blacklist-checker/).
- A warm-up tool is connected and running.
- Your first list is verified and your first email has been through the [Cold Email Grader](https://prosyo.com/tools/cold-email-grader/).

## How long does email warm-up take?

For a brand-new domain and inbox, plan on three to five weeks before full cold email volume: around two weeks of warm-up only, then two to three weeks of ramping. An older domain with a sending history can move faster. With the default inputs (5 a day, plus 2 a day, target 30, new domain) the planner reaches full volume on day 28.

There is no instant shortcut. Warm-up builds a history of normal, positive interactions, and history takes time to accumulate. Teams that skip it usually spend longer recovering from spam placement than they would have spent warming up.

## Does warm-up still work?

Warm-up tools have limits worth understanding. Mailbox providers weigh real recipient behaviour (replies from the people you actually email, how they treat your messages) far more than any warm-up network. Warm-up helps a new inbox establish a baseline of normal activity, and it can keep placement steady at low volumes, but it cannot rescue a campaign sent to a poor list or with irrelevant copy. Use warm-up as a foundation, then let real replies do the heavy lifting by writing to the right people.

## Ramping more than one inbox

If you are launching several inboxes, as you usually will, warm them up in parallel on the same schedule and start campaigns across all of them together, each at the planned daily volume. Do not concentrate early volume on one inbox. Use the [Volume and Inbox Calculator](https://prosyo.com/tools/cold-email-volume-calculator/) to work out how many inboxes your meeting goal needs, then warm all of them up.

## Common warm-up mistakes

### Starting cold sends on day one

The most common and most costly mistake. A new domain sending cold email immediately often lands in spam within days.

### Ramping too fast

Jumping from 10 to 50 a day overnight undoes the trust you built. Steady increases look natural.

### Stopping warm-up at full volume

Keep warm-up running alongside campaigns; it provides a steady stream of positive signals between cold sends.

### Sending to unverified lists during the ramp

Bounces during warm-up are especially damaging because the domain has little history to absorb them.

### Ignoring weekends

Some teams pause cold sends at weekends but keep warm-up running, which keeps activity natural. Either approach works; keep it consistent.

## Warming up a domain after a deliverability problem

If an existing domain has started landing in spam, a “re-warm” often helps: drop cold volume sharply (to around a quarter of what it was), keep warm-up running, send only to your best-fit, verified prospects, and ramp back up over two to three weeks while watching the signals above. Fix the cause first: check authentication with the [Domain Health Checker](https://prosyo.com/tools/domain-health-checker/) and blocklists with the [Blacklist Checker](https://prosyo.com/tools/blacklist-checker/).

## What warm-up actually does

Mailbox providers decide where to put your mail largely from history: how much you have sent before, how recipients reacted, and whether your pattern looks like a person or a machine. A new inbox has no history, so its first messages are judged with extra caution. Warm-up gives it a history in three ways:

- **Volume history**: a steady, growing daily count instead of a sudden spike.
- **Engagement history**: messages that are opened, replied to and, if they land in spam, marked as not spam.
- **Authentication history**: a record of messages that consistently pass SPF, DKIM and DMARC.

Real conversations count most. During the warm-up-only period, send genuine emails from the new inbox too: introductions to colleagues, replies to vendors, newsletter sign-ups you will read. Real two-way mail is the strongest warm-up signal there is.

## Choosing your target volume

Your target cold emails per inbox should come from your plan, not from a number you saw online. Work out total daily volume with the [Volume and Inbox Calculator](https://prosyo.com/tools/cold-email-volume-calculator/), then divide it across enough inboxes that each stays at a moderate level. Many teams keep each inbox between 30 and 50 cold emails a day once warmed up. If your plan needs more, add inboxes instead of raising the target.

## Warm-up for LinkedIn accounts

The same idea applies to LinkedIn. A new or quiet account that suddenly sends many connection requests and messages draws attention. Start with a small number of personalised connection requests a day, respond to messages, post or comment occasionally, and increase activity gradually over a few weeks. Keep connection notes short and genuine, and withdraw old pending invitations regularly.

## Example schedule

New domain, 5 cold emails on day 1, increase 2 a day, target 30:

| Days | Phase | Cold emails per day |
| --- | --- | --- |
| 1–14 | Warm-up only | 0 |
| 15 | Ramp starts | 5 |
| 16–20 | Ramp | 7, 9, 11, 13, 15 |
| 21–27 | Ramp | 17, 19, 21, 23, 25, 27, 29 |
| 28 onwards | Full volume | 30, with warm-up still running |

## Sending windows and time zones

Send cold email during your recipients’ working hours, spread across the day rather than in one burst at 9:00. A natural pattern (a few messages every hour, with random gaps) looks like a person working through their outreach. Avoid sending the whole day’s volume within minutes, and schedule by the recipient’s time zone when your list spans regions. Weekend sends can work for some audiences but generally get fewer replies; many teams keep cold sends to weekdays while warm-up continues every day.

## Google Workspace versus Microsoft 365 inboxes

Both work well for cold email when set up properly, and many teams use a mix so their sending matches the mix of providers their prospects use. A few practical differences: Google Workspace requires you to generate DKIM and click Start authentication; Microsoft 365 needs two CNAME records and DKIM enabled in Defender. Microsoft tenants can also have outbound spam policies that limit recipients per day for new accounts, so ramp new Microsoft inboxes gently. Whichever you use, confirm authentication with the [Domain Health Checker](https://prosyo.com/tools/domain-health-checker/) before day one.

## Signals you are ramping too fast

- Warm-up messages start landing in spam.
- Test emails to your own Gmail and Outlook accounts go to spam or Promotions.
- Replies dry up even though volume rose.
- Bounce messages mention rate limits or “try again later”.
- Your sending tool reports deferrals or throttling.

Any of these means hold the current volume, or step back a few days, until the signal clears.

## After warm-up: keeping reputation healthy

- **Keep warm-up running** at a low level alongside campaigns.
- **Keep daily volume steady.** Large swings from day to day look less natural than a consistent rhythm.
- **Verify every new list** before it enters a sequence.
- **Rotate fresh copy** so you are not sending identical text in large numbers.
- **Check domain health monthly** and after adding any new sending tool.
- **Retire tired inboxes.** If an inbox’s placement keeps slipping despite fixes, rest it and shift its volume to fresh, warmed-up inboxes.

## Glossary

- **Warm-up**: gradually building a new inbox’s sending history and reputation.
- **Ramp**: the period of increasing cold volume after warm-up only.
- **Warm-up network**: a pool of inboxes that exchange, open and reply to warm-up messages.
- **Inbox placement**: whether mail lands in the inbox, a tab or spam.
- **Re-warm**: reducing volume and rebuilding an existing inbox’s reputation after a problem.

## What to send during warm-up only

The warm-up-only phase is not just a tool running in the background. Real activity from the inbox makes the strongest signals:

- Introduce yourself to a few colleagues and partners from the new address and get replies.
- Reply to existing threads that you forward to the new inbox.
- Subscribe to two or three newsletters you actually read, and open them.
- Send your first cold emails only to your warmest, best-fit prospects when the ramp starts.
- Add a signature and profile photo so replies show a real person.

## Frequently overlooked: replies need somewhere to go

Warm-up and cold sends both generate replies. Make sure the inbox is monitored, or forwarded to a monitored inbox, from day one, and that the domain’s MX records are correct. Unanswered interested replies are the most expensive mistake in outbound, and a domain that cannot receive replies looks suspicious to mailbox providers. The [MX Lookup](https://prosyo.com/tools/mx-lookup/) confirms the domain receives mail.

## Frequently asked questions

### How long should I warm up a new email domain?

Around two weeks of warm-up only, then two to three weeks of gradually increasing cold sends, so three to five weeks in total before full volume for a brand-new domain.

### How many emails should a new inbox send per day?

Start with around 5 to 10 cold emails a day after the warm-up-only period and add 1 to 3 a day, up to a target that many teams keep around 30 to 50 per inbox.

### Do I need a warm-up tool?

It helps a new inbox build a baseline of normal activity, but it does not replace good targeting and verified lists. Use one during the first weeks and keep it running alongside campaigns.

### Can I skip warm-up if my domain is old?

An older domain with a normal sending history needs a shorter warm-up, but not none if it has never sent cold email. The planner uses a short warm-up-only period for older domains.

### What if my bounce rate rises during the ramp?

Pause, clean your list, and resume at the previous day’s volume. Bounces are especially damaging while a domain is new.

### Can I send cold email during warm-up?

Only after the warm-up-only period, and then at low volume that increases gradually. Sending cold email from a brand-new inbox on day one is the most common cause of early spam placement.

### Is this warm-up planner free?

Yes, with no sign-up. It runs in your browser.
