Mailwarmup vs Swokei Email Warmup

Mailwarmup is a web service that aims to raise sender reputation by generating positive email engagement through a shared network of more than 10,000 inboxes. After users connect an account using SMTP and IMAP details, it sends scheduled messages on their behalf. Network inboxes open and reply to messages, mark them important, and remove them from spam. A dashboard tracks warmup results, including messages removed from spam, categories, and email deliverability. Listed integrations include Gmail, Outlook, and SMTP; users can control sending and limits. Other listed tools include a Mail Health Score, blacklist monitoring, delivery statistics, blacklist removal prompts, and AI ramp ups in beta. Warmup messages can be filtered into a separate folder using the subject keyword “WUA.” There is no free plan, but a 7-day trial is offered. Starter costs $19 a month for one email account and up to 50 positive engagements per day. Growth is $49 a month for three accounts and up to 50 engagements daily; Scale is $99 a month for eight accounts and up to 100 daily; Powerhouse is $149 a month for eight accounts and up to 300 daily. Warmup does not guarantee inbox placement.

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.
