Key benefits of using Warmy?

Set and forget

Full automation. Simply connect your mailbox and let “Adeline”, our artificial intelligence (AI) engine, warm up the mailbox at the optimal pace.

Analyzing hundreds of parameters a day, interacting with real people on your behalf, and making sure you hit the inbox in every single email you send.

Full progress monitoring

Clear and transparent process, so you can stay informed and in control.

Perfect email activity

The messages you send will automatically be opened, marked as important, and taken out of the spam folder to increase your reputation as a sender dramatically.

A dedicated dashboard for your whole team

With Warmy you can simply manage everything in one place by accessing your employees' and clients' information as well as the functionality of the mailboxes, subscriptions, etc. Share the results with your team and watch your business grow!

Warmy Features

  • Compatible with major email providers: Connect Gmail, Google Workspace, Outlook, Microsoft 365 and mailboxes with SMTP access. Warmy also supports integrations with sending platforms.
  • Automated email warm-up: Warmy gradually increases sending volume and exchanges emails with mailboxes in its network to help build sending history and sender reputation. Messages that land in spam are moved to the inbox.
  • AI-driven warm-up plans: Adeline AI uses mailbox history, reputation and placement signals to set a warm-up schedule and review it as new data comes in.
  • Inbox placement testing: See whether emails land in the inbox, promotions tab or spam folder across providers, and track deliverability over time.
  • Email seed lists: Send campaigns to seed mailboxes that open and engage with messages, then review where those messages landed.
  • Email verification: Check individual addresses or bulk lists for invalid and risky contacts before sending.
  • DMARC monitoring: View DMARC reports in a readable dashboard, identify sending sources and inspect SPF and DKIM alignment.
  • Deliverability insights: Monitor inbox placement, domain reputation and email configuration to identify issues that need attention.

How Warmy pricing works

Warmy uses a subscription based on warm-up volume, connected mailboxes and selected features, rather than charging per seat. Team members share the plan’s mailbox capacity and monthly quotas. Placement tests use shared per credit allowances across connected mailboxes; Warmy asks customers to confirm their allowance with its team.

Monthly subscriptions are generally billed after the billing period, while annual subscriptions are billed in advance and renew for another annual term unless cancelled. Warmy does not identify an annual-only feature on its pricing page. Its Custom plan is arranged with its team around sending needs; annual prepayments are non-refundable.

  • More connected mailboxes may change the subscription cost, but adding team members does not create a separate seat charge.
  • Greater warm-up volume may require a different plan or a custom quote.
  • More placement testing may require a different allowance; Warmy does not publish an overage mechanism.
  • Applicable taxes are added to fees.
  • Currency conversion, transfer or payment-processing charges may apply. Warmy says core tools have no separate add-on fees.

There is no continuing free plan. The free trial requires no credit card, but is limited to one user and one mailbox unless Warmy provides otherwise. It also limits daily warm-up activity; continued use after the trial requires a paid subscription.
