Warmerly's done-for-you email accounts are sending mailboxes it hosts on a domain you choose. Warmerly publishes MX, SPF, DKIM and DMARC for you, creates the mailboxes and starts warmup on every one. They cost $0.99 to $2.99 per mailbox a month depending on your plan, and they never use one of your plan's mailbox slots.
Most of the work in cold email is standing up infrastructure: a domain, DNS that authenticates correctly, mailboxes, and warmup. With hosted mailboxes you choose the domain and the names, and Warmerly does the rest.
The hosted mailboxes appear in your mailbox list next to any mailboxes you connect yourself, with the same warmup, the same campaigns and the same reply inbox. They are not Google or Microsoft accounts. They are ordinary IMAP and SMTP mailboxes on Warmerly's own mail servers.
They are built for when you need more sending mailboxes, not more admin. They cost $2.99 per mailbox a month on the Free and Starter plans, $1.99 on Growth and $0.99 on Agency, and they never use one of your plan's mailbox slots. The product is named OneMail in the app and on the OneMail page.
You choose the domain and the names. The rest runs by itself, and every stage is visible, including a failure and its reason.
Search for a new domain and you see whether it is free and its yearly price before anything is charged. Or connect a domain you already own, by changing two nameservers at your registrar or by adding the records by hand.
MX, SPF, DKIM and DMARC are published for you, plus the bounce records. On the manual route the app lists every record you need to add and carries on by itself once they resolve.
If a domain you connect already receives email, Warmerly stops before changing any MX record and suggests a separate sending domain, so your existing inboxes keep working.
Type the names you want, such as hello@ or sam@, from 1 to 100 in one order. Add more to the same domain later, with no DNS to touch.
Each mailbox joins warmup as soon as it exists and ramps up by itself: 4 messages a day at the start, growing with every day it has been warming. Nothing to switch on.
The mailboxes sit in the same list as every other mailbox. Campaigns start gently: the default daily campaign limit is 30, and warmup keeps running alongside. Replies land in your Inbox and stop that person's follow-ups.
Everything is done while signed in, under Accounts → Add → OneMail mailbox (we host it). A visitor browsing the website will not see the buy-a-domain option until they have an account. The support assistant, can also look up the live price of a specific domain name for you.
Every route ends in the same place: mailboxes in your list, authenticated and warming.
Search a name in the wizard. It shows whether the name is available and the yearly registration price, live from the registrar, before anything is charged. You never touch DNS.
The price depends on the ending, such as .com or .co, so there is no single figure to quote. The domain is registered with you as the registrant.
Whether it is at Namecheap, GoDaddy, Cloudflare or anywhere else, you change the domain's nameservers at your registrar to the two the wizard shows, and Warmerly then manages the records. There is no domain fee, and you do not need to buy anything from Warmerly.
If you would rather keep your current DNS provider, choose "Add records manually instead". The wizard lists MX, SPF, DKIM and DMARC records, plus a bounce MX and SPF record and, when offered, an optional tracking CNAME. Add every required one, because skipping one hurts deliverability. Warmerly checks for them about every minute and carries on by itself once they resolve. Only your DNS provider decides how long that takes.
Shown once you have a hosted domain. There is no DNS to touch, and warmup starts on the new mailboxes straight away. Two domains with two mailboxes each is fine, and so is one domain with many.
A mailbox that has already finished warmup on a domain Warmerly runs, so it can send campaigns from the start. It costs the same rate as any hosted mailbox. The option only appears in the wizard when some are in stock, and the mailbox is on Warmerly's domain, not your own.
The bigger your Warmerly plan, the lower the per-mailbox rate. There is no minimum order, and ready-warmed mailboxes cost the same rate.
| Your plan | Per mailbox a month | 10 mailboxes | 25 mailboxes | 100 mailboxes |
|---|---|---|---|---|
| Free and Starter | $2.99 | $29.90 | $74.75 | $299.00 |
| Growth | $1.99 | $19.90 | $49.75 | $199.00 |
| Agency | $0.99 | $9.90 | $24.75 | $99.00 |
The rate is set by the plan your workspace is on, so it drops as you move up. It is the same for every hosted mailbox, including a ready-warmed one when some are in stock, and there is no minimum order.
The examples below add the plan price and the hosted mailboxes together, to show what a month costs. A domain, if you buy one through Warmerly, is separate.
The Starter plan is $19 a month. 10 hosted mailboxes at $2.99 each.
The Growth plan is $49 a month. 25 hosted mailboxes at $1.99 each.
The Agency plan is $179 a month. 100 hosted mailboxes at $0.99 each.
The Free plan is $0 a month. A card is needed to buy hosted mailboxes. 3 hosted mailboxes at $2.99 each.
A domain bought through Warmerly has its yearly registrar fee shown before you pay. A domain you already own costs nothing extra.
Charged per mailbox, monthly, on your Warmerly subscription. It recurs until you delete the mailbox. On the Free plan, hosted mailboxes are charged on a subscription of their own, and a card is needed.
Never used. Your plan's mailbox limit (1 on Free, 5 on Starter, 25 on Growth, 100 on Agency) stays free for the mailboxes you connect yourself. The full plans are on the pricing page.
The examples use the monthly USD prices on the pricing page and facts page, and ignore tax and any domain fee.
Each hosted mailbox is a working sender from the moment the stages complete.
Bought through Warmerly or connected by you, and kept separate from your main domain.
MX, SPF, DKIM and DMARC published, so mail is authenticated from the first send. On a domain bought through Warmerly, or one connected by nameservers, Warmerly publishes the records itself, and on domains it manages, records that drift are put back.
hello@, sam@, sales@: you choose. One order holds up to 100, and you can add more to the same domain later.
Threaded warmup emails with other mailboxes, answered automatically, growing each day the mailbox warms. It starts at 4 messages a day and reaches 50 a day by day 30. Warmup messages are separate from the daily campaign limit. Connected Gmail mailboxes have a ceiling of 40 a day and connected Outlook mailboxes 30; those ceilings are for mailboxes you connect yourself.
SPF, DKIM, DMARC and MX status, blocklist checks and a health score out of 100, on the mailbox's page, with the fix when something needs attention. The full warmup method is on the email warmup page and in how warmup works.
Send from hosted mailboxes like any other mailbox. Replies land in your Inbox, alongside every other mailbox, and stop that person's remaining follow-ups.
You decide what you add, when you pause it and what happens if you stop.
| What | What you can do |
|---|---|
| Domains | Buy a new one, connect one you own by nameservers or by hand, or add mailboxes to a domain you already host with us. |
| Count | 1 to 100 mailboxes in one order, more whenever you like. Delete one and its charge stops; its data is removed after the retention period. |
| Warmup | Pause and resume warmup for one mailbox or a selection. Warmup grows with the days a mailbox has been warming. |
| Sending | A new hosted mailbox sends campaigns from a few a day, climbing as it warms. The default daily campaign limit is 30. We advise against raising it early. |
| Pause, resume, delete | On the Hosted mailboxes page you can search, filter by domain or status, and pause, resume or delete one mailbox or many. |
OneMail mailboxes are billed on your plan, so cancelling asks what should happen to them. Keep them, and they move to a OneMail subscription of their own on the same card, at the per-mailbox price for workspaces on Free, and keep working. Close them, and they work until your plan ends, are then suspended, and their mail is deleted 30 days later.
Before the plan ends you can download each mailbox's mail as an .mbox file from its menu under Accounts. Taking a plan again within those 30 days lets you restore closed mailboxes. If you cancel in the billing portal, or the plan ends because a payment failed, they are closed. The full wording is in the refund and cancellation policy.
Domains registered through Warmerly for hosted mailboxes are registered with you as the registrant. If you close your mailboxes, Warmerly stops renewing the domain and it lapses at the end of the term already paid for. To move it to another registrar, choose Request a transfer code on the mailbox's settings page. Registrars do not allow a transfer in the first 60 days after registration, and time left on a registration is not refunded.
For a domain you brought yourself, remove the MX, SPF and DKIM records that point to Warmerly if you close your mailboxes, or mail to those addresses will bounce.
Hosted mailboxes share Warmerly's servers, so Warmerly looks after their reputation as closely as you do.
| Record | What it is for |
|---|---|
| MX | Points the domain at Warmerly's mail server so replies can arrive. A sending domain that cannot receive replies is no use. |
| SPF | Says which sending addresses are allowed to send for the domain. An existing SPF record is merged rather than replaced. |
| DKIM | Warmerly signs every message with the domain's own key, and the public half is published in DNS. |
| DMARC | Tells receiving providers what to do when a message fails. An existing DMARC record is left alone. |
| Bounce records | A bounce address on your own domain, with its own MX and SPF, so bounces come back to Warmerly rather than to your inbox. |
Warmerly never touches your main company domain unless you ask it to. If a domain you connect already receives mail, both DNS routes stop before changing any MX record and recommend a separate sending domain, so your existing inboxes keep working. Reputation attaches to the sending domain, so keeping cold email on its own domain keeps it away from the one your everyday mail runs on.
Every mailbox shows its SPF, DKIM, DMARC and MX status and its blocklist results. Warmerly watches every mailbox and pauses sending when reputation drops. Hosted mailboxes share Warmerly's servers, so a mailbox that develops deliverability problems is paused automatically. The details are in how our email infrastructure works.
| Lane | What it is | How it is kept apart |
|---|---|---|
| Paid | Hosted mailboxes that customers order, on their own domains or on domains bought through Warmerly. | Customers' own domains. |
| Ready-warmed | Mailboxes that have already finished warmup, so a customer can buy one and send. | Domains Warmerly owns and uses only for this. Once bought, the mailbox moves to the buyer's workspace with its history. |
| Free | The free mailbox every new account gets. | Separate domains, and separate servers with sending addresses of their own. |
Lawful outreach to business contacts, with no bought or rented lists and no consumers without the consent their country's law requires. The rules are in the Acceptable Use Policy, and accounts that break them can be suspended.
Both work the same way inside Warmerly: same warmup, same campaigns, same reply inbox. You can use both in one account.
| Compare | Bring your own mailboxes | Hosted by Warmerly |

| Warmup | Included. 4 a day at the start, up to 50 by day 30, with ceilings of 40 a day on Gmail and 30 on Outlook | Starts on its own the moment the mailbox exists, on the same day-by-day ramp |
| Good for | Mailboxes you already own and want to keep using | New sending capacity on a separate domain, or a ready-warmed mailbox when one is in stock |
Connecting your own mailboxes is covered on the connect and manage mailboxes page, and the hosted side on the hosted domains and mailboxes page.
These decide whether hosted mailboxes fit what you are doing.
The mailboxes live on Warmerly's own mail servers. If you need to send from Google Workspace or Microsoft 365, connect those instead. Both kinds work together in one account.
Correct DNS removes a whole category of problem, but it does not buy reputation. Mailboxes on a new domain start cold, which is why they go straight to warmup and not straight to campaigns.
The app shows five stages and runs them for you, but how long they take depends on the domain and on DNS. We would rather say that than quote a figure.
It is only offered when some are in stock, and the mailbox is on a domain Warmerly runs, not your own. Do not plan around it being available.
The domain is yours. The mailboxes are hosted by us, so moving means standing them up on another host and pointing MX at it, as with any mail migration.
Warmerly pauses a mailbox that develops deliverability problems. If you want one replaced, contact support with the address and it will be looked at.
Hosted mailboxes suit anyone who wants cold email on its own domain and would rather not buy, configure and warm each mailbox by hand.
Start cold email on a new domain without opening a DNS panel or buying a mailbox seat elsewhere. A free sandbox mailbox comes with every account to try warmup first. See cold email for founders.
Give each client their own sending domain and mailboxes. Hosted mailboxes sit outside your plan's mailbox limit, and the Agency plan has the lowest rate and client workspaces. See cold email for agencies.
Add sending capacity in a few clicks. New mailboxes appear next to your connected ones, with the same warmup, campaigns and reply inbox. See cold email for B2B sales teams.
Keep cold email away from the domain your everyday inbox runs on. Warmerly does not touch your main company domain unless you ask it to.
Every signup gets one free mailbox on a domain Warmerly owns, already warming, so you can watch warmup work before you buy anything. It is for warmup and testing and cannot run campaigns. What the free mailboxes are.
Sign up free, open Accounts and add hosted mailboxes. DNS and warmup are handled for you, and your free mailbox is warming from the start.
