Inbox Warmup vs Swokei Email 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.

Swokei Email Warmup is a web-based outreach service for web design agencies and freelancers. It examines prospects’ websites in a headless browser, captures screenshots, and assesses design, copy, performance, and conversion paths. It can use those findings to write personalized outreach emails and send them from the user’s mailbox. Leads can be imported from spreadsheets, pasted rows, Google Sheets, a website URL, or a saved library. Positive replies can become deals in the built-in CRM, which supports pipeline stages, tasks, notes, files, and deal values. Mailbox warmup is included on every plan, with an automatic 30-day ramp and per-mailbox health and bounce-risk indicators. Swokei supports Gmail, Outlook, Yahoo, custom domains, and SMTP connections; for Gmail, it says it monitors only messages it sent. The Free plan costs nothing and starts with 20 credits, but has no mailboxes and does not allow sending. Paid plans start at $42/mo billed annually. The listed daily email limit is 50, and the warmup network is shared.
