Mailwarm vs Warmy: What the Plans Actually Include

Reviews and directories sometimes mix up tools with similar names, including "mail warm" products with very different prices. This page compares Mailwarm at mailwarm.com. Here's what each vendor's public pages said when we checked them in November 2026:

How Warmy and Mailwarm Work in Practice

01

Email Warmup Process

Warmy email warmup works with your existing email provider and uses a protected network of over a million real Google Workspace, Microsoft 365 and consumer inboxes. It sends during working hours in the recipient's time zone, ramps up gradually, and slows down at night and on weekends.

Warmy simulates natural engagement: it opens emails, replies to them, marks them as important and rescues them from spam. You can choose warmup providers and use your own templates and topics in 30+ languages. Auto-archive keeps warmup messages out of your inbox.

How Mailwarm does itMailwarm email warmup sends warm-up emails from your mailbox to its network of 50,000+ aged, real inboxes that engage with those emails. Each plan caps warm-up at 50, 200 or 500 emails a day.
02

Using Seed Lists

Warmy adds a 500,000+ US seed list across Gmail, Outlook, Yahoo, corporate and regional providers, including mobile seeds on real US devices. When you send your campaigns to the list, the seed accounts open emails, move them out of spam, scroll and click links, adding real engagement to your actual campaigns on top of peer-to-peer warmup.

How Mailwarm does itMailwarm tracks inbox vs spam per mailbox. It doesn't list a seed list across providers.
03

Authentication and Sender Reputation

Start with authentication. SPF, DKIM and DMARC are the core protocols in Google's sender requirements. Warmy's DMARC monitoring shows who's sending emails using your domain, which checks fail, and the exact record to change. Free SPF and DMARC generators create correct records in minutes. Warmy also tracks domain and IP reputation and sends alerts when a signal drops.

How Mailwarm does itMailwarm checks SPF, DKIM and DMARC and shows spam signals and placement. It doesn't list DMARC report analysis or blacklist monitoring.
04

Measuring Results

Warmy's placement tests run outside the warmup network and break down results by provider, showing inbox, Promotions, and spam placement. Scheduled auto-tests keep your baseline up to date. Keep the template and provider mix consistent between tests. If most of your recipients use Microsoft 365, watch those results before raising volume, even when the overall score looks healthy.

How Mailwarm does itMailwarm runs continuous placement tracking with live inbox vs spam reporting.
05

Expert Help and Support

This is Mailwarm's focus: every plan includes calls with a deliverability expert. Warmy takes a different approach, with 24/7 human support on every plan, plus Deliverability Academy and a private community for teams that want to build the skills in-house.

06

Setup and Providers

Both tools are self-serve and work with Gmail, Outlook, Microsoft 365, Yahoo, Zoho and SMTP mailboxes. Warmy connects through OAuth or SMTP/IMAP in minutes and includes API access for teams that want to automate warm-up.

07

Teams and Agencies

Mailwarm's user seats vary by plan: one on Starter, two on Growth and five on Scale. Warmy includes an agency dashboard for teams that manage warm-up for several clients.
