Automated email warmup that keeps your outreach out of the spam folder
Mailboxes are warmed automatically without daily manual work: connect an account, set your niche, and the system handles the rest.
Your mailboxes exchange messages with other real accounts in the network, generating the positive replies and opens that providers look for.
AI writes warmup email content that fits your language, business niche and working hours so threads look natural.
Track domain and sender reputation, blocklist status and deliverability scores for each connected inbox.

Cold email outreach, AI sequences and inbox-placement infrastructure in one platform
Describe your offer once and MailOptimal drafts a full multi-step sequence, then rewrites each line using real prospect details such as company, role and recent triggers. Follow-ups stop automatically the moment a reply arrives.
Send from InfraOptimal dedicated-IP mailboxes starting around $1.00 per mailbox per month, or use pre-configured Google Workspace, Microsoft 365 and Azure mailboxes. SPF, DKIM, DMARC, MX and rDNS are configured for you, and existing mailboxes can be connected in minutes.
Automatic warmup runs on every inbox while the platform monitors domain authentication, daily blocklists and inbox placement by provider. Each sender gets a 0-100 health score with suggested one-click fixes and safe daily sending ramps.
Search 700M+ verified B2B contacts and 42M+ companies with 25+ person, company and buying-signal filters. Verified emails, mobile numbers and direct dials can be pushed straight into a campaign without exporting CSVs.
