Cold email volume, engineered for cost
100 mailboxes on a single domain, 500 sends a day, one flat price. Azure infra is the lowest cost-per-email when you send at scale.
Why Azure for cold email
When you're sending serious volume, per-mailbox pricing adds up fast. Azure flips the economics: a flat $30 per domain covers up to 100 mailboxes, and the ultra-conservative 5-emails-per-day-per-mailbox limit keeps every inbox pristine while the sheer number of mailboxes delivers the volume — 500 clean sends per domain per day. The result is the lowest cost-per-send of any option once you're past a few thousand emails a month. Spread risk across many low-volume mailboxes; pay a fraction per email.
