In their own words
Inbox Warmup
Inbox Warmup connects SMTP infrastructure, authenticates domains, warms sending activity, monitors reputation signals, manages replies, and controls campaigns from a web and API dashboard. It supports SMTP ports 465 with SSL/TLS, 587 with STARTTLS, and compatible custom ports. Checks include SPF, DKIM, DMARC, Return-Path, ownership, and tracking records. Warm-up automation increases activity gradually, rotates sending, respects mailbox limits, and can pause when health signals need attention. Campaign tools provide templates, personalization, timezone scheduling, hourly and daily limits, and pause or resume controls. Listed mailbox providers include Gmail, Workspace, Outlook, Yahoo, and IMAP accounts, with Google Postmaster and Yahoo sender-data integrations. Launch costs $39 a month after a $1 first seven days; Growth is $99 a month and Professional $199 a month on the same terms. Agency pricing is custom. Credits reset monthly and do not roll over.
