Inboxes and domains in the dashboard
Managed Google, Microsoft and SMTP inboxes for cold email, with domains and DNS set up for you
Prices in US dollars as ScaledMail's pricing page showed them on 11 October 2026.
ScaledMail sets up and manages the domains and inboxes that sales teams and agencies use to send cold email, on Google Workspace, Microsoft 365 or SMTP, with DNS records configured for them. It suits B2B outbound teams using a sequencer such as Smartlead or Instantly. Google inboxes cost $3.50 each a month, Microsoft domains $50 each with 25 inboxes, and there is no long-term contract.
ScaledMail registers or connects domains, creates the inboxes and configures SPF, DKIM and DMARC records, with packages ready within 24 to 72 hours.
Packages can mix Google Workspace, Microsoft 365 and SMTP inboxes in any split, which ScaledMail says spreads sending across providers with different reputation signals.
Pick a daily or monthly sending volume and providers, and the builder works out the domains and inboxes needed and the monthly price, with optional reporting add-ons.
Pre-aged, pre-warmed domains let teams send from the first day instead of waiting about two weeks for warm-up, or replace domains that have been burned.
Each inbox is capped at 25 cold emails a day on Google and 10 on Microsoft or SMTP, with customers on isolated tenants rather than shared infrastructure.
Every customer gets a dedicated Slack channel with ScaledMail's cold email team, and an API is documented for managing infrastructure programmatically.

“One of the best, if not the best, providers out there.”
“It saves so much time and money to be able to use this service to purchase inboxes for cold email”
“Very great support. They're always there to fix problems.”
ScaledMail sells cold email infrastructure: it buys or connects your domains, creates the inboxes, configures SPF, DKIM and DMARC, and hands the inboxes over ready to plug into a sending tool.
It doesn't write or send campaigns itself. Warm-up and sequences run in a separate sequencer such as Smartlead, Instantly, EmailBison or PlusVibe, and ScaledMail says that is deliberate so you don't pay twice for warm-up. Each customer gets isolated tenants rather than shared infrastructure, a dedicated Slack channel for support, and set-up within 24 to 72 hours. Pre-aged, pre-warmed domains are on offer for teams that need to send from day one.
ScaledMail prices in dollars per month: Google Workspace inboxes are $3.50 each, Microsoft Outlook is $50 per domain with 25 inboxes, and SMTP is $3.75 per domain with 4 inboxes.
The real cost depends on how many emails you want to send a day. ScaledMail caps sending at 25 emails a day per Google inbox and 10 a day per Microsoft or SMTP inbox, so volume decides how many inboxes and domains you need. Its worked example for 2,000 emails a day, split across all three providers, comes to 42 domains and 218 inboxes for $397.75 a month, plus $256 if you add the optional reporting on every account. ScaledMail's FAQ puts most teams at that volume at around $400 to $500 a month. The site doesn't mention VAT or sterling prices, so UK buyers pay in dollars.
To businesses, largely yes; to individuals, no without consent. The UK's PECR rules let you email limited companies, LLPs and public bodies without prior consent, but treat sole traders and some partnerships as individuals.
The ICO's guidance says every marketing email must show who it is from and give a working way to opt out, and that you should keep a do-not-email list of businesses that object. UK GDPR still applies when the address names a person. ScaledMail provides the inboxes, not legal advice, so responsibility for who you email stays with you.
Buying inboxes directly is cheaper per inbox but leaves you to register domains, set DNS records and watch reputation yourself. ScaledMail bundles that set-up and monitoring into its price.
The case for ScaledMail is time and support: reviewers on Trustpilot mostly praise the Slack support and quick fixes, and the company says it manages more than 230,000 inboxes. Rival infrastructure sellers it compares itself with include Inframail, Maildoso, Mailforge, Zapmail and MailDeck, and some sequencers such as Instantly sell inboxes too. None of these appear in this section, so for newsletters or shop email rather than cold outreach, beehiiv or Privy are the tools to look at instead.
The levers ScaledMail describes are the provider mix, the sending volume and skipping optional extras.
Packages are billed monthly with no long-term contract, so volume can be adjusted or cancelled as campaigns change.

No. ScaledMail says warm-up runs in your sequencer, such as Smartlead, Instantly, EmailBison or PlusVibe, and recommends about two weeks before sending at volume. Pre-warmed domains are available if you need to start straight away.
No long-term contract is required. ScaledMail says packages are billed monthly and you can change volume, swap providers or cancel at any time.
Up to 25 cold emails a day per Google inbox and 10 a day per Microsoft or SMTP inbox. Warm-up emails run separately in your sequencer.
Yes. You can buy domains through ScaledMail or connect ones from another registrar such as GoDaddy or Namecheap, and its team configures the DNS records either way.
ScaledMail says each customer gets separate, isolated tenants, so infrastructure isn't shared, and that Microsoft rotates the tenant IP every 15 days.
