How to use this planner

1
Enter your target volume
The number of emails a day you want to send once you are fully warmed up, not what you send today.
2
Describe your domain honestly
A new domain and a poor reputation both need a slower ramp. Overstating either produces a schedule that gets you filtered.
3
Pick a pace
Recommended suits most senders. Choose Conservative if you have been filtered before, Aggressive only if you can watch the numbers daily.
4
Follow the schedule and watch two numbers
Export the CSV and send to it. Slow down if bounce rate passes 1% or complaints pass 0.1%, well before Google's published 0.3% limit.

Definition

What is an email warmup planner?

An email warmup planner is a calculator that turns a target sending volume into a day-by-day ramp schedule.

You supply your daily volume, list type, domain age and current deliverability. It returns how many emails to send each day, how many of those should be engagement seeds running underneath your own volume, the day you reach full rate, and the seed rate running underneath it. How long you keep seeding after that is your call: if placement holds on a clean, engaged list you may need less of it, and if it slips you may want more. This tool plans the ramp; you execute it from your own sending platform. To measure where your mail actually lands while you ramp, run a free placement test. You still do the sending; what an email warmup service supplies is the seed inboxes and the engagement behind it.

Monitor Your Metrics

Two numbers decide whether a ramp is working. Slow down if bounce rate exceeds 1% or spam complaints exceed 0.1%. 0.3% is the figure Google publishes as its limit, but complaints are a lagging signal, so waiting for it means acting after the damage.

< 1%

Bounce rate

Track it in your ESP dashboard. Above this, stop increasing volume and clean the list before you continue. A high bounce rate is the fastest way to lose a new domain.

< 0.1%

Spam complaints

Track it in Google Postmaster Tools. Google publishes 0.3% as its limit but recommends staying under 0.1%, and by the time you reach the limit filtering has usually already started.

daily

How often to check

Both are lagging indicators, so watch the trend rather than a single day. To see where your mail is actually landing, run a free placement test.

Why Plan the Ramp?

Ramping too fast is what gets filtered

Mailbox providers read a sudden jump in volume as suspicious however good your content is. A schedule keeps the increase inside what your reputation can carry.

Engagement is what builds reputation

Volume alone teaches providers nothing. Opens and replies are the signal, which is why the plan runs a seed volume underneath your campaign rather than just pacing your sends.

Your numbers, not a generic table

Schedules come from InboxAlly's warmup model using your target volume, domain age, list type and current deliverability. A new domain and an established one get genuinely different plans.

Email Warmup Planner FAQ

How long does email warmup take?

Most senders reach their target volume in two to four weeks, but the honest answer is that it depends on your starting point. A brand-new domain ramping to 5,000 a day takes considerably longer than an established domain returning to 100 a day.

The planner gives you the specific number of days for your inputs rather than a general range.

What bounce and complaint rates should I watch during warmup?

Slow your ramp if bounce rate exceeds 1% or spam complaints exceed 0.1%. Google publishes 0.3% as the limit, but it also recommends staying under 0.1%, and by the time you reach 0.3% filtering has usually already started.

Track bounce rate in your ESP dashboard and complaint rate in Google Postmaster Tools. Both are lagging indicators, so react to the trend rather than a single day.

Can I warm up a domain by sending to my own list?

Partly, but only if your list actually engages. Warmup works because mailbox providers see opens, replies, and inbox placement, and a list that ignores you teaches them the opposite lesson.

This is the gap seed sends fill: they guarantee positive engagement signals alongside your real campaigns while your reputation is still forming.

Is this planner free?

Yes. The planner is free, with no signup and no email required. Enter your numbers and export the schedule as CSV.

It is separate from InboxAlly's paid warmup service, which supplies the seed inboxes and the engagement behind your sends.

Do I have to keep seeding after the ramp?

Not necessarily. The plan covers 30 days, and what you do after that depends on your own numbers rather than a fixed rule.

If your placement holds, your list stays clean and engagement is genuine, you may need less seeding — or none. If bounce or complaint rates drift, or you add cold contacts or a new sending platform, more support usually helps. Watch the two thresholds above and let them decide rather than the calendar.

What is the difference between the planner and the warmup service?

The planner tells you what schedule to follow. It is a free calculator that outputs daily send targets you run yourself from your own platform.

You always do the sending. What InboxAlly's email warmup service supplies is the other end: seed inboxes that receive those sends and genuinely open, read and reply to them, which is what builds the engagement history.

You Send. InboxAlly Engages.

A schedule only works if something on the other end opens, reads and replies. InboxAlly supplies that engagement automatically, every day, so your reputation builds while you run your campaigns.
