Terlido
Terlido is a cloud-based platform for teams running cold-email campaigns from connected Gmail, Microsoft 365, or SMTP/IMAP mailboxes. Warmup and campaigns share one daily per-mailbox send budget, with recipient-domain throttling, suppression controls, and automatic pauses at bounce or spam thresholds. Before sending, it checks SPF, DKIM, DMARC, and MX records; unsubscribe headers remain on. Sequences combine email, WhatsApp, LinkedIn, and call steps. LinkedIn steps become prepared tasks for a person, not automated account actions. Terlido Newsletter is free for up to 10,000 subscribers. The platform also offers a unified inbox, contact management, campaign analytics, two-way HubSpot sync, and a REST API and MCP server on eligible plans; agent use follows sending limits and workspace controls. Teams can manage outreach campaigns and replies from one workspace.

emailcampaign.ai
Most cold email tools assume the mailboxes, domains and DNS records already exist and already authenticate. emailcampaign.ai starts one step earlier. A daily sending target becomes a priced build, and one approval registers the sending domains, creates the mailboxes on Google Workspace, Microsoft 365 or dedicated servers, writes SPF, DKIM and DMARC and verifies every record against public resolvers, and warms each mailbox for two to three weeks before the first campaign. 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.
