Buying bulk email accounts for cold email means buying new Google Workspace or Microsoft 365 inboxes on domains you own, not aged accounts from a marketplace. Here is what to buy, where to buy it, what 100 accounts cost and what to stay away from.

Looking for an email list? This page is about the accounts you send cold email from. If you want contact data, the addresses you send to, that is a different product, and we explain below why bought lists are a poor start. Disclosure: PureMail sells cold email accounts; see how we review.
First, know what you are buying
Search for “buy email accounts” and four different products come up. Only the first two belong in a cold email setup.
Buy
New Google Workspace or Microsoft 365 mailboxes created on domains registered to you, by a reseller or by you.
Risk: Low. The accounts are licensed, the domains are yours, and you can move providers.
Buy
The same kind of mailbox, warmed up by the provider before delivery so you can send sooner.
Risk: Medium. You pay two to three times the price, and often the domains are the provider’s.
Avoid
Old Gmail, Outlook.com, Hotmail or “phone-verified” accounts sold in bulk on marketplaces.
Risk: High. They break Google’s and Microsoft’s terms, belong to someone else and get suspended.
Avoid
Contact data: other people’s addresses to send to. Not accounts to send from.
Risk: Different product. Bought lists bounce and hurt the inboxes you send from; build and verify your own.
The expensive shortcut
Marketplaces sell old Gmail, Outlook.com and Hotmail accounts by the hundred, often labelled “aged” or “PVA” (phone-verified). They look like the fastest way to get cold email accounts in bulk. They are not:
New business accounts cost about $3 an inbox a month, on domains you control. That is the cheapest way to buy email accounts that are still there next month.
Step by step
The same steps work for 20 accounts or 2,000. We use 100 as the example: enough for about 3,000 cold emails a day.
Look up the MX records of a sample of your prospects’ domains. Gmail-heavy lists go on Google Workspace, Outlook-heavy lists on Microsoft 365. Many teams buy both and split the list.
Divide your daily target by about 30 cold emails per warmed inbox. 3,000 emails a day needs 100 accounts. The cold email calculator does this for any volume.
Plan two inboxes per domain, five at most, so 100 accounts need about 50 domains. Use .com variants of your brand, never your main company domain. Register them in your own name.
Order the mailboxes on those domains from a cold email infrastructure provider, or buy Google Workspace or Microsoft 365 licences yourself. Check minimums, billing cycle and whether setup is included.
Add SPF, DKIM, DMARC and MX records on each domain and confirm they pass. Done-for-you providers do this for you; self-serve dashboards automate most of it.
Connect each inbox to your sequencer over OAuth, turn on warmup and wait two to three weeks before sending cold email. Then ramp to 20 to 40 a day per inbox.
Other providers charge about $250 to $450 a month for the same 100, depending on billing and prepayment; the cheap cold email inboxes guide prices each one at 10 to 500 inboxes.
Skip the wait?
A new inbox needs two to three weeks of warmup before it sends cold email. Pre-warmed accounts skip that, at a price.
| Option | Price | What you get |
|---|---|---|
| Zapmail pre-warmedChecked September 28, 2026 | $6–$8 a mailbox | Plans of 3, 12 and 30 mailboxes with 1, 4 and 10 domains; extra domains $15 a year |
| Premium InboxesChecked October 1, 2026 | $3.50 per 4-week cycle | Not pre-warmed, but warmup starts on delivery and flagged inboxes are replaced |
| Primeforge pre-warmedChecked October 5, 2026 | Not published | Sold separately from its $4.50 slots |
| Standard inbox + your sequencer’s warmup | From $2.90 an inbox | Warmup is free in Instantly, Smartlead and most sequencers; you wait two to three weeks |
Pre-warmed email accounts make sense for a launch you cannot move. For everything else, the maths favours standard inboxes: at $6 to $8 a mailbox, a pre-warmed account costs two to three times a standard one every month, not just the first. The warmup is also tied to the provider’s domain and account, so it does not come with you if you switch.
The cheaper route is to buy standard inboxes now, turn on your sequencer’s free warmup, and buy the next batch before you need it. Rotating a new set in every few months means you never wait.
Microsoft
“Bulk Outlook accounts” means two different things. Marketplaces sell personal Outlook.com and Hotmail accounts, which Microsoft suspends when they start sending outbound mail. What works for cold email is Microsoft 365: business Outlook mailboxes on your own domains, sending through Microsoft’s Exchange Online servers.
You can buy Microsoft 365 from Microsoft, where the cheapest mailbox is Exchange Online Plan 1 on a yearly subscription, or from a Microsoft 365 reseller that sells inboxes monthly and sets them up for outbound. Microsoft throttles new tenants for their first 60 days, so ramp slowly. Send Outlook inboxes to prospects on Outlook, typically enterprise, finance, healthcare and public sector.
PureMail sells Microsoft 365 inboxes for cold email at the same price as Google Workspace inboxes, from $2.90 an inbox, so you can buy both and split your list by the recipient’s provider.

FAQ
What people ask before they buy cold email accounts in bulk.
01
From a cold email infrastructure provider that sells Google Workspace or Microsoft 365 inboxes on your domains: PureMail, InboxKit, Zapmail, Premium Inboxes and others. You can also buy licences from Google or Microsoft and set them up yourself. Do not buy accounts from marketplaces that sell aged or bulk personal accounts.
02
Buying business email licences, such as Google Workspace or Microsoft 365, from the vendor or an authorised reseller is normal. Buying someone else’s personal Gmail or Outlook.com accounts breaks Google’s and Microsoft’s terms, and the accounts can be closed at any time. Cold email itself must follow CAN-SPAM in the US: a real sender, a physical address and a working opt-out.
03
About $250 to $450 a month for 100 Google or Microsoft inboxes, depending on the provider and on whether you prepay. On PureMail, 100 inboxes cost $310 a month with the setup included. Add about 50 domains at around $12 a year each.
04
Only if you cannot wait two to three weeks. Pre-warmed mailboxes cost about two to three times a standard inbox, often sit on the provider’s domains, and the warmup history goes with them if you leave. Most teams buy standard inboxes and use the free warmup in their sequencer.
05
Yes, as Microsoft 365 mailboxes on your own domains, from a Microsoft 365 reseller or directly from Microsoft. Do not buy bulk Outlook.com or Hotmail accounts: those are personal accounts and Microsoft suspends them. PureMail sells Microsoft 365 inboxes at the same price as Google Workspace.
06
Email accounts are the inboxes you send from. An email list is contact data, the addresses you send to. Cold email needs accounts, plus a list you build and verify yourself. Bought lists tend to bounce, and bounces damage the reputation of the accounts you send from.
07
About one per 30 cold emails a day. 500 a day needs about 17 accounts on 9 domains, 3,000 a day needs 100 on 50. Keep two accounts per domain, five at most.
