The Big Picture: Why Warmy Exists

Email outreach is only useful if it actually reaches the primary inbox. Warmy is a cloud platform built to protect one precious metric: deliverability. By simulating human-like conversations, repairing domain reputation, and teaching mailbox providers to trust you, it keeps cold emails out of the spam tab and in front of real prospects. 

If you have a new domain, a previously black-listed IP, or simply want a healthier sender score, Warmy aims to do the invisible heavy lifting so you can press Send with confidence.

Warmy’s Stand-Out Features

AI Engine “Adeline”

Warmy’s secret sauce is an adaptive learning engine called AI-powered Adeline. It analyzes hundreds of parameters per mailbox and makes more than 20 million micro-decisions each day to decide when, how often, and to whom your warm-up messages should be sent. The algorithm constantly re-calibrates based on live data so you never outrun the safe limits of your provider.

Hands-Off Warm-Up Automation

Once you connect an inbox, Warmy schedules gradual sending, opens, clicks, and replies that look just like genuine conversations. You can “set and forget” the process, or tweak daily caps, time windows, and pacing to match your risk tolerance. For agencies, multiple mailboxes can be managed from one dashboard without hopping between accounts.

Deliverability & Placement Testing

Before a real campaign goes live, Warmy can fire test emails to a seed list spanning Gmail, Outlook, Yahoo, and niche providers. The platform then tells you whether each message landed in Inbox, Promotions, or Spam, and flags SPF, DKIM, DMARC, and DNSBL issues. It is essentially x-ray vision for your sender reputation. 

Real-Mailbox Engagement Network

Warmy’s interactions happen between thousands of active human inboxes—not dummy accounts. Messages are opened, scrolled, links clicked, and spam-trapped emails are manually rescued and marked Important. These organic-looking signals train ISPs to trust your domain faster than purely automated activity could. 

Multilingual & Custom Templates

Need to warm a Spanish or German domain? Warmy supports more than 30 languages and lets you upload your own templates or pick from topic-based examples. This helps you build a region-specific reputation and maintain brand voice while warming up. 

Agency-Ready Dashboard & Reporting

Color-coded charts show daily health scores, open rates, spam recovery stats, and inbox placement trends. You can invite teammates, white-label PDF reports for clients, and even monitor several sending domains side-by-side.

Warmy FAQ

What exactly is “email warm-up”?

Warm-up is the practice of sending low-volume, high-engagement messages from a new or dormant mailbox to build a positive sender reputation. Without it, mass emails are more likely to hit spam.

How long does the warm-up process take?

Most users see healthy inbox placement within one to four weeks, but domain age, previous reputation, and daily volume goals can shorten or lengthen that timeline.

Which email providers are supported?

Warmy works with Gmail, Outlook, Yahoo, Zoho, Amazon SES, SMTP gateways, and virtually any IMAP/SMTP-compatible service.

Can I cancel anytime?

Yes. Warmy bills month-to-month, and you can pause or cancel from the billing panel without contacting support.

Is my data secure?

Mailbox credentials are stored using bank-grade encryption, and Warmy never accesses email content beyond the synthetic warm-up threads it generates.

Does Warmy replace my cold-email platform?

No. It runs in parallel. Once your domain is trusted, you still send campaigns through your outreach tool of choice, but with far fewer bounces and spam flags.

What happens if my emails still hit spam?

The dashboard will surface the root causes—missing DNS records, blacklists, or content triggers—and suggest concrete fixes. Additional placement tests can be run on demand to validate improvements.
