emailcampaign.ai
Email Campaign LLC
Most cold email tools assume the mailboxes, domains and DNS records already exist and already authenticate. emailcampaign.ai starts one step earlier.

The same platform then runs the outreach: sequences within per-mailbox daily caps, a unified inbox that attributes each reply to the send it answers, reply classification, and inbox placement tests at Gmail and Outlook. For agencies a second product sits inside the first: a webmail on each client's own hostname, where the client's administrator connects a Google or Microsoft mailbox without sharing a password, masks addresses by policy, approves outbound forwarding rules and reviews deleted mail.Starting Price: $39/month -
