3.8/ 5

Warmy automates email warm-up with AI, real-time placement tracking, seed-list tests, and Google Postmaster data, backed by SOC 2 compliance and G2 Spring 2025 recognition. The trade-offs are real: prices aren't published, so a demo is needed for a volume quote, and headline results are vendor-reported. Overall, it's a solid deliverability pick if you can live with demo-based pricing.

Pros

Pros:AI-driven warm-up automates sender reputation building, with a claimed 25-second mailbox setup instead of weeks of manual inbox engagement routines
Pros:Real-time placement monitoring shows whether emails land in the inbox, spam, or promotions, with domain reputation and DNS configuration metrics to pinpoint causes
Pros:Separate B2B and B2C warm-up networks match warm-up activity to your actual audience — business mailboxes for Google Workspace and Microsoft 365 targets, consumer mailboxes for Gmail, Yahoo, and Outlook recipients

Cons

Cons:No dollar prices are published anywhere; all plans use volume-based custom quotes that require booking a demo, making upfront budgeting difficult
Cons:Headline results such as 2.3x higher open rates, 3x higher click rates, and 35% fewer bounces are vendor-reported figures, not independently verified
Cons:The 7-day trial is short relative to how gradually sender reputation actually builds, so it may be hard to validate warm-up results before paying

Best for

Cold email and outreach teams that need new domains warmed before big sends
Marketing teams fighting falling open rates on Gmail, Outlook, or Yahoo
Agencies managing deliverability across multiple client mailboxes

Free trial: Yes — 7 days

What is Warmy?

You craft the perfect email, hit send, and it vanishes into spam. If your open rates keep sliding, poor deliverability is often the reason. Warmy tackles that with AI-driven email warm-up, real-time placement insights, and domain reputation monitoring, so more of your messages reach the primary inbox on Gmail, Outlook, and Yahoo.

Warmy is an all-in-one email deliverability platform built around AI-powered warm-up. It gradually builds trust for your domains and mailboxes so B2B and B2C emails avoid spam filters. Beyond warm-up, it offers seed-list testing, deliverability insights, and Google Postmaster integration.

It's aimed at marketers, sales teams, founders, agencies, and affiliates — anyone who relies on cold or campaign email and can't afford to land in spam.

Should you choose Warmy?

Quick buyer guidance before you compare plans or click through.

Choose it if

You use mainstream providers like Gmail, Outlook, Yahoo, or Microsoft 365
You want automated warm-up instead of slow manual inbox routines
You want clear insight into whether emails land in inbox, spam, or promotions
You prefer to try before buying — the trial needs no credit card
You value human support, including a free one-on-one deliverability consultation

Skip it if

Headline results like 2.3x opens and 3x clicks are vendor-reported, not independently verified
You must connect your own mailbox and domain, so it won't help without access to your sending setup
A 7-day trial may be short for judging reputation gains, which build gradually
Warm-up is an ongoing process, so it's not a one-time fix you can set and forget

Next steps before buying

1Run Warmy's free email deliverability test to see where your emails land today
2Open the pricing page and confirm which plan fits your number of mailboxes
3Verify your provider is supported — the site lists Gmail, Outlook, Yahoo, Microsoft 365, SendGrid, and others
4Use the 7-day trial (no credit card, cancel anytime) to judge warm-up progress firsthand
5Book the free one-on-one consultation if you want expert guidance before committing

Ease of use

The site emphasizes a 25-second setup and a simplified new dashboard. Customer testimonials describe the interface as simple and intuitive, with fast, helpful support. A no-credit-card trial and a free consultation lower the barrier further. Based on these signals, non-technical users should be able to start without deep deliverability expertise.

Warmy Key Features

🔥 AI-Powered Email Warm-Up

Your domain builds sender trust automatically. Warmy's AI gradually ramps up sending activity so spam filters learn to trust you. Connect your mailbox — setup takes about 25 seconds, not weeks of manual routines.

Use it before cold outreach or big campaigns so messages reach the primary inbox instead of spam.

📊 Real-Time Deliverability Insights

See exactly where your emails go — inbox, spam, or promotions. The dashboard shows metrics on deliverability, domain reputation, and DNS configuration, so issues stop being guesswork. Check it before a big send to catch problems early.

That visibility helps you keep your domain healthy and campaigns on track.

✨ Email Seed List Testing

Test before you send. Warmy's email seed list shows how your messages actually land across providers, so you can spot placement problems before real recipients do. Run it alongside the deliverability test for a clear picture of where you stand — and fix issues while they're still cheap to fix.

✨ Fits Your Existing Stack

Connect the tools you already use. Warmy works with Gmail, Outlook, Yahoo, Microsoft 365, and sending platforms like SendGrid and Mailgun. Google Postmaster integration adds deeper Gmail data, and email verification helps keep your lists clean.

There's also an API, so teams can fold deliverability checks into their own workflows.

✨ Free Tools That Do the Basics

Start free, no signup needed. Warmy offers tools that handle common deliverability tasks:

Free email deliverability test
SPF and DMARC generators
Template checker and cold email sequencer

There's also a mailbox calculator, signature builder, and Inbox Academy video lessons. Use them to set things up correctly from day one.

Pricing notes

Warmy's page does not display any specific plan prices; it uses volume-based pricing where you pay for the volume of warm-up emails you need. A 7-day free trial is available with no credit card required, and a custom plan can be shaped around your sending needs.

Warmy prices its plans by volume, so your cost scales with how much email you send. There are three options: B2B sender, B2C sender, and a Custom plan built around your exact needs.

Here's a closer look at each one.

B2B sender

Best For: Teams emailing professional providers like Google Workspace and Microsoft 365 Other Features:

Volume-based pricing
Google Postmaster integration
Deliverability monitor
Dedicated deliverability expert

This plan warms up your domains and IPs using a network of business mailboxes. The goal is simple: your emails land in the primary inbox when you're reaching professional inboxes. If your outreach targets companies and work accounts, this is your lane. You'll book a demo to get a quote matched to your sending volume.

B2C sender

Best For: Teams emailing personal providers like Gmail, Yahoo, and Outlook Other Features:

Volume-based pricing
Google Postmaster integration
Deliverability monitor
Dedicated deliverability expert

This one works the same way but warms up through a network of consumer mailboxes. It's built for senders whose audience uses personal email accounts. If you're running campaigns to everyday consumers, this plan is the better match. Like the B2B option, you'll book a demo to get volume-based pricing.

Custom plan

Other Features:

Volume-based pricing
Google Postmaster integration
Deliverability monitor
Dedicated deliverability expert
Dedicated customer success manager

High-volume senders and agencies with unusual needs should start here. Warmy's deliverability experts tailor the plan to your setup, and you also get a dedicated customer success manager. It's the best pick when neither standard track fits your sending pattern. Book a demo and the team will help you find the right solution.

A few practical notes. Warmy offers a 7-day free trial with no credit card required, and you can cancel anytime. Payments run through PayPal using Visa, MasterCard, or American Express, and your information is protected by 256-bit SSL encryption. Because pricing is volume-based, it's worth confirming your exact volume limits and quote with the team before you commit.
