A cold email stack has six parts, and you pay for most of them every month.
Secondary domains come first. You buy lookalike domains that are close to your main brand and send only from those. A typical secondary domain costs about $12 per year, and most senders put 3 inboxes on each domain.
Inboxes are the mailboxes on those domains. A typical Google Workspace or Microsoft 365 inbox costs about $7.20 per month, and inboxes are usually the biggest line in the whole stack because you need a lot of them.
The sending platform is the tool that sends the campaigns, rotates inboxes and handles replies and unsubscribes. A typical entry plan costs about $37 per month, and larger plans cost more as volume grows.
Warmup is the service that builds sending history on new inboxes before campaigns start. Warmup is often included with a sending platform, and standalone warmup tools usually charge per inbox.
Verification checks each address before you send, so bad addresses bounce less and hurt your domains less. A typical price is about $6 per 1,000 emails checked.
Data is the list itself, bought from a data provider or built by hand. Data prices vary the most of any part, so this calculator leaves data out and focuses on the sending stack you pay for every month. Plan your setup with the Email Warmup Calculator, find domains with the Secondary Domain Finder, and check a domain with the Domain Health Checker.
First, sending from expensive primary inboxes. Your main domain inboxes cost the same per seat, but a burned main domain costs far more in lost trust and broken company email. Secondary domains are cheap insurance.
Second, using too few domains and pushing each one too hard. Sending 100 emails a day from one inbox on a crowded domain looks cheap until the domain is flagged, and then you pay to replace domains, inboxes and warmup time all over again.
Third, retail platform bundles. Bundles that wrap domains, inboxes and sending into one marked up package can cost far more than buying the same parts separately at typical market rates.
Cost per 1,000 emails is the total monthly stack cost divided by your monthly volume, times 1,000. It lets you compare stacks of different sizes on one fair basis. As volume grows, fixed costs like the platform spread thinner, so the number usually falls. If your number is far above the worked example below, look at the inbox line first, because it drives most of the total.
We ran this calculator with the default inputs: 30,000 emails per month, 22 sending days, 30 emails per inbox per day, 3 inboxes per domain, a domain cost of $12 per year, an inbox cost of $7.20 per month, a platform cost of $37 per month and a verification cost of $6 per 1,000 emails.
The calculator returned 46 inboxes and 16 domains. It gave monthly costs of $331.20 for inboxes, $16.00 for domains, $37.00 for the sending platform and $180.00 for verification. The total was $564.20 per month and $6,770.40 per year, which is $18.81 per 1,000 emails sent.
For 30,000 emails a month, a typical stack costs $564.20 per month with the default prices in this calculator. Small senders pay less because they need fewer inboxes and domains, and large senders pay more in total but usually less per 1,000 emails.
Divide your monthly volume by your sending days and then by the emails one inbox sends per day, and round up. For 30,000 emails over 22 days at 30 per inbox per day, you need 46 inboxes.
Divide your inboxes by the inboxes you put on each domain, and round up. At 3 inboxes per domain, 46 inboxes need 16 domains.
The worked example lands at $18.81 per 1,000 emails for the full stack. A number in the high teens is typical at this volume with market rate inboxes. Much higher usually means pricey inboxes or a marked up bundle.
No, never. Cold campaigns pull spam complaints and bounces that damage any domain they touch. If that domain is your main one, your normal company email suffers too. Buy cheap secondary domains instead.
You need verification from somewhere, either a separate tool or one built into your sending platform. Bad addresses bounce and hurt your domains, so budget about $6 per 1,000 emails for checking.
Inbox, domain, platform and verification prices all differ by provider and by volume, and bundles mark the same parts up by different amounts. Change every price in this calculator to your quotes and compare stacks on the same basis.
