Start sending cold email without warm-up

Skip the 14-day warm-up with pre-warmed inboxes: $3 per inbox per month, 15 cold emails a day from day one, 90-day minimum, and the real tradeoffs versus warming your own.

Start sendingRead the API

The short answer

To start cold email without a warm-up, lease pre-warmed inboxes. On EmailPal they cost $3 per inbox per month, send 15 cold emails a day from the moment you claim them, and are listed only after at least 14 days of warming, with the measured inbox rate shown before you pay. Handover usually takes minutes. The tradeoffs are a 90-day minimum term, a fixed cap of 15 a day, no custom names, and EmailPal keeps the domain. Ten inboxes cost $30 a month ($90 over the minimum), against $6 a month to warm ten mailboxes you own plus a 14-day wait.

Pre-warmed inboxes are leased mailboxes on domains EmailPal owns, already through a warming ramp of at least 14 days against a network of real Gmail, Outlook and Yahoo inboxes, with the inbox rate they measured attached to each listing. You claim them from the Pre-warmed tab or with POST /inventory/prewarmed, they are yours to send from in minutes, and warming keeps running at no extra charge. They cost $3 per inbox per month with a 90-day minimum, they sit outside your plan’s mailbox allowance, and each can send 15 cold emails a day. You do not own the domain, you do not choose the names, and you cannot raise the cap. If you can wait two weeks and want to own the domain, warming your own mailboxes at $0.60 is cheaper.

How it works, step by step

  1. Step 1

    Have a payment method and a verified list ready

    Claiming starts a recurring charge, so the account needs a subscription and a card on file. Verify the list before the first campaign: pre-warmed inboxes die from a dirty list as fast as any other mailbox. EmailPal pauses a campaign at 5% hard bounces after at least 200 sends and warns at 3%.

  2. Step 2

    Read the shelf before you pay

    GET /inventory/prewarmed lists available inboxes with their email, domain, health score, inbox rate, warming day and a previously_leased flag. It also returns the price (monthly_cents), the minimum term (min_term_days) and the warming floor (min_warming_days). The list is not a reservation: availability moves between reads.

    GET /api/public/v1/inventory/prewarmedbash
    curl https://www.emailpal.io/api/public/v1/inventory/prewarmed \
  -H "Authorization: Bearer $EMAILPAL_API_KEY"

  3. Step 3

    Choose by measured placement, not only by price

    There is no minimum health score on the shelf: each inbox shows its own number and you decide. Prefer a high inbox rate on a high warming day, and look at previously_leased, which tells you whether the address has had an earlier tenant. In the dashboard, open Pre-warmed, expand a domain to see its addresses, and claim the domain as a set so the names read as one company.

  4. Step 4

    Claim the inboxes

    POST /inventory/prewarmed with mailbox_ids from the list (up to 25 per request), or with a count to take the healthiest still available. Send an Idempotency-Key header, because this starts a recurring charge with a minimum term. The response is 202 with a job_id. In the dashboard the confirmation dialog quotes the domain, the number of inboxes, the monthly total and the 90-day term, and nothing is billed until you confirm.

    POST /api/public/v1/inventory/prewarmedbash
    curl -X POST https://www.emailpal.io/api/public/v1/inventory/prewarmed \
  -H "Authorization: Bearer $EMAILPAL_API_KEY" \
  -H "Idempotency-Key: prewarmed-claim-001" \
  -H "Content-Type: application/json" \
  -d '{"mailbox_ids": ["mbx_2c81f0", "mbx_2c81f1"]}'

  5. Step 5

    Wait for the handover job

    The job rotates each mailbox’s password and assigns it to your account. EmailPal’s help center says this usually takes minutes. Poll the job; result.leased lists the email, first name and last name of what you actually received. If your bank has to confirm the charge, the response says awaiting_payment, nothing is handed over yet, and the inboxes are assigned automatically when the payment clears, which can take up to 24 hours for some cards.

    GET /api/public/v1/jobs/{job_id}bash
    curl https://www.emailpal.io/api/public/v1/jobs/job_5c9e18 \
  -H "Authorization: Bearer $EMAILPAL_API_KEY"

  6. Step 6

    Pick the inboxes in a campaign, or export SMTP and IMAP

    The addresses appear under Mailboxes. Select them in an Engage campaign, or export SMTP and IMAP credentials (which needs an admin key) into another sequencer. Passwords are not on the inventory list, so take them from the export.

  7. Step 7

    Send at 15 a day or less, and leave warming on

    Set the cold limit at 15 or lower. Warming is already running and is included in the $3, so do not pause it. Do not add a forwarding domain, an extra DKIM key or a second SPF record, because the authentication is already done.

01

What you are actually leasing

A pre-warmed inbox on EmailPal is a hosted SMTP and IMAP mailbox on a domain EmailPal registered and parked. EmailPal describes the pool domains as parked for 90 days or more, authenticated with SPF -all, DKIM (RSA-2048 and Ed25519), DMARC p=reject and MX, and warmed against a network of real inboxes at Gmail, Outlook and Yahoo. An inbox is listed only after at least 14 days of warming, and the inbox rate those inboxes measured is attached to the listing. Warming and placement checks continue after you claim the inbox and are inside the $3.

It is a lease of the mailbox, not a purchase of the domain. The mailbox does not count against your plan’s included mailboxes or domain slots, and you are not charged the $0.60 warming price on top. The addresses and personas are assigned before listing, so you cannot rename them, and a bundle is claimed by domain, so you cannot add extra addresses to it later. They are not Google Workspace or Microsoft 365 seats.

02

What the listing does and does not tell you

The listing shows health score, inbox rate, the warming day and whether the address was leased before. The inbox rate measures where warming messages landed, which is evidence about the mailbox’s history rather than a promise about your campaign. A scraped list, a heavy HTML pitch or too many links can still reach spam from a mailbox with a strong measured rate.

EmailPal does not gate the shelf on a minimum health score. Each inbox shows its own figure and the choice is yours. Inboxes that had an earlier tenant carry previously_leased, because finding out afterwards that an address had a previous tenant would be a surprise. Choose with that in front of you.

03

How long until you can send

EmailPal’s help center says handover is usually minutes: a job rotates passwords and assigns the mailboxes, and there is no registrar wait and no ramp on your side. That is the part you control least. If a card needs bank confirmation, the claim is held and the inboxes are assigned when payment clears. And if the shelf is empty, nothing can be claimed until more inboxes finish their warming.

Compare that with a mailbox you own: EmailPal marks a mailbox campaign-ready after 14 days of warming on the standard profile, and the conservative schedule on the warm-up page then steps volume from about 5 a day to 15 over three weeks. campaign-ready is a flag and not a lock, so nothing blocks you from sending earlier, but doing so on an unwarmed mailbox is how domains get filtered.

04

Cost math against warming your own mailboxes

Ten inboxes leased: 10 × $3 = $30 a month, and $90 over the 90-day minimum. Ten mailboxes you own, warmed: 10 × $0.60 = $6 a month, or $18 over 90 days, as long as they sit within your plan’s included mailboxes (50 on Starter). Ten mailboxes need 2 domains at 5 each, about $10 each for .com, so $20 once. The owned path is then $38 over the first 90 days against $90 leased, a difference of $52, before the plan fee that you pay either way.

If your plan’s mailboxes are already used up, each owned mailbox also costs $1 a month in overage, so ten cost 10 × $1.60 = $16 a month, $48 over 90 days, $68 with the domains. The gap narrows to $22 over 90 days. Leasing is never cheaper per month than owning, and the lease price pays for time and a measured placement history.

What the difference buys is about two weeks. Waiting 14 days with ten mailboxes at 15 a day defers 10 × 14 × 15 = 2,100 cold emails, and if you then step up gradually the gap is wider. Whether that is worth $52 depends on how quickly a campaign has to start. After the 90 days the lease continues month to month at $30 for ten, against $6 or $16 for mailboxes you own, so leasing is best used to start now rather than as a permanent fleet.

Volume is bought in 15s. 150 cold emails a day takes 10 inboxes at $30 a month. 1,000 a day takes 67 inboxes at $201 a month plus the plan fee, compared with about $126 a month all in (plan fee included) on your own mailboxes in the scale-up worked example, but about four weeks sooner. A claim takes up to 25 inboxes per request.

05

The tradeoffs, plainly

You do not own the domain. A lease moves the mailbox, never the name, and you do not get Google Postmaster access to it. When the lease ends, the address goes back to the pool and may be leased again, so you cannot take the sender identity with you, and you cannot set the domain’s website redirect either, because the pool domain has no single owner.

The minimum term is 90 days. Releasing before day 90 does not cancel the remaining minimum, and deleting a leased mailbox before the term ends is refused over the API. After day 90 it is month to month, and release stops future charges without prorating the current month.

The cap is 15 cold emails a day per inbox and EmailPal does not let you raise it. EmailPal’s reason is that the measured placement has to survive the first week of real campaign copy. If you set a sequencer to a higher number, every mailbox is still stopped at a hard ceiling of 100, and the point of the lease is lost well before that.

There are no custom domain names or handles. If you want a brandable domain you choose, register or bring your own and warm the mailboxes, which costs $0.60 per inbox and two weeks.

06

Mixing leases and owned mailboxes

The practical use is to lease a small number of inboxes to start a campaign this week while owned mailboxes on your own domains warm in the background, then move volume to the owned fleet and let the leases run out. Leases do not use plan slots, so the two sit side by side. See the scale-up page for the owned-fleet arithmetic, and the secondary-domains page for why even owned sending domains should not be your main one.

Campaign-ready is not the point here

Pre-warmed inboxes skip the 14-day wait, but they do not skip list hygiene. A mailbox gets a warning email at 3% rejected mail and is paused at 5%, and a campaign pauses at 5% hard bounces after 200 sends, whatever the inbox started with.

This is not for you if

  • You want to own the domain you send from. Pre-warmed inboxes are leased on domains EmailPal keeps, and when the lease ends the address goes back to the pool.
  • You need brandable names or to choose mailbox handles. Personas are assigned before listing and cannot be edited.
  • You need more than 15 cold emails a day from one inbox. The cap cannot be raised on a lease; more volume means more inboxes.
  • You cannot commit to 90 days. Releasing early does not cancel the remaining minimum charge.
  • You need a Google Workspace or Microsoft 365 seat. These are EmailPal-hosted SMTP and IMAP mailboxes.
  • You expect a warmed inbox to fix a dirty list. The measured inbox rate describes the mailbox’s history, not how your list or copy will be received.
  • You want to point the domain at your own website. Pool domains do not support the website redirect.
FAQ

Common questions

What is a pre-warmed inbox on EmailPal?

A leased, EmailPal-hosted SMTP and IMAP mailbox on a domain EmailPal owns, listed only after at least 14 days of warming against a network of real Gmail, Outlook and Yahoo inboxes, with the measured inbox rate shown before you pay. It costs $3 a month, sends 15 cold emails a day from day one, and keeps warming for free.

How much do pre-warmed inboxes cost and what is the minimum term?

$3 per inbox per month with a 90-day minimum, then month to month. Ten inboxes are $30 a month, $90 over the minimum. Releasing before day 90 does not cancel the remaining minimum. Leases do not use plan mailbox slots and warming is not charged on top.

How many cold emails can a pre-warmed inbox send per day?

15 a day from the moment you claim it, and EmailPal does not let you raise that on a lease. Ten inboxes send 150 a day. For more volume, claim more inboxes, up to 25 per request.

How long until I can send after claiming?

EmailPal’s help center says usually minutes. A job rotates the passwords and assigns the mailboxes to your account, and there is no ramp on your side. If your bank needs to confirm the payment, the claim is held and the inboxes are assigned automatically when it clears, which can take up to 24 hours for some cards.

Is it cheaper to warm my own mailboxes than to lease?

Yes, if you can wait. Ten owned mailboxes warm for $6 a month ($18 over 90 days) within your plan allowance, against $30 a month ($90) for ten leases, before domains and the plan fee. Warming takes 14 days. The lease pays for time and a measured placement history, not for a lower unit cost.

Do I own the domain, and what happens when I stop leasing?

No. The domain stays with EmailPal. After the minimum term, releasing the lease stops the monthly charge and the address is handed back to the pool rather than destroyed, so it may be leased to someone else. If you want to keep your sending domain, register or bring your own and warm it.

How do I claim pre-warmed inboxes by API?

List the shelf with GET /api/public/v1/inventory/prewarmed (read key), then POST the same path with mailbox_ids (up to 25) or a count (1 to 25) and an Idempotency-Key header. You get a 202 with a job_id to poll at /api/public/v1/jobs/{job_id}, and result.leased lists what you received. In the dashboard, use the Pre-warmed tab and confirm the monthly total.
