Warm before the first campaign

Every mailbox warms automatically and joins your sender rotation once it is ready, so new infrastructure never sends cold.

What is InfraOptimal?
Our own sending platform, built for cold outreach rather than office email. Every mailbox gets an IP dedicated to your workspace, and prices run from $2.00 down to $1.00 per mailbox a month depending on volume and billing cycle, with a minimum of 10 mailbox slots.
Should I buy InfraOptimal or Google and Microsoft mailboxes?
Under 10 mailboxes, or when you mail a short list of named accounts, Google and Microsoft at $4 a mailbox are the simpler pick. Past that, InfraOptimal costs about a quarter as much and the sending reputation belongs to you alone.
What do Google, Microsoft and Azure mailboxes cost?
Google Workspace and Microsoft 365 mailboxes are $4 per mailbox a month. Azure is $25 per tenant a month and includes 100 mailboxes on the same domain, which works out to $0.25 a mailbox.
Do I need to know anything about DNS?
No. We configure SPF, DKIM, DMARC and domain redirects automatically on every mailbox we provision.
How fast can I start sending?
Provisioning and authentication typically complete in minutes; warmup then ramps each inbox to safe volume automatically.
Can I connect mailboxes I already own?
Yes. Link existing Google Workspace or Microsoft 365 accounts in seconds and they inherit warmup and monitoring.
How many mailboxes should I run?
It depends on volume. Sender rotation spreads sends across all of them, so more mailboxes means safer scale.
