Why Trust This Guide

I’ve run Warmy on my own sending domains for eight months and tested every tool inside it. Everything here comes from real screens, not vendor claims.

Warmy is an email warm up tool built for one job: getting your mail out of the spam folder.

Most people connect an inbox, hit start, and never open the rest of the dashboard.

That is a waste, because the testing tools are where the valuable insights sit.

Once you see how Warmy works end to end, it is far easier to improve email deliverability.

This guide walks through every feature, step by step.

Warmy Pro Tips and Shortcuts

After eight months with this warm up tool, these are the habits that moved the numbers.

Keyboard Shortcuts

Hidden Features Most People Miss

• Per-inbox scheduling: Match warming hours to your working day, so activity looks human.
• Weekend pause: Turn off weekend sends for B2B domains and get the same results with less volume.
• Domain health history: Compare this month against last month to prove the warm up is working.

The dashboard rolls all of that into one view:

Check it weekly, not daily. Warming is slow by design.

Warmy Common Mistakes to Avoid

Mistake #1: Sending Cold Emails During Warm Up

Mistake #2: Ignoring DNS Before Connecting

Mistake #3: Warming One Inbox for a Whole Team

Warmy Troubleshooting

Problem: Warm Up Emails Still Land in Spam

Cause: The domain reputation was already damaged before you started.

Fix: Switch to slow mode, keep replies on, and give it a full 70 days.

Problem: Mailbox Keeps Disconnecting

Cause: Expired app passwords or a security policy on Google Workspace.

Fix: Reconnect with a fresh app password and allow the connection in admin settings.

Problem: Deliverability Score Will Not Move

Cause: Your email content is triggering filters, not your sending history.

Fix: Run the template checker, cut links, and rewrite with relevant content.

📌 Note: If none of these fix your issue, contact Warmy support.

Warmy Pricing

Here’s what Warmy costs in 2026:

Free trial: Yes — a seven day trial covering the warm up and testing tools.

Money-back guarantee: Not published. Billing stops at the end of your current cycle.

Every tier is quoted per sender account, so the bill grows with more inboxes:

💰 Best Value: B2B Sender — the right fit if you want to warm one or two mailboxes. Ask sales about the starter plan tier before you commit to a year.

For example, a two-person agency running four mailboxes will pay far more than a single founder chasing high deliverability on one domain.

Quick picks:

• Best overall: Warmy — deepest testing, including the seed list feature and template checks.
• Best budget: Warmbox — cheapest way to warm a single inbox.
