01

Email warmup process

Warmy email warmup runs through your existing provider on 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, replies, marks emails 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 meters plans by daily warmup volume: 50, 200 or 500 emails a day, shared across the plan's mailboxes.
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.

Send your campaigns to the list and the seed accounts open emails, move them out of spam, scroll, and click links. Combined with peer-to-peer warmup, this warms new mailboxes and domains much faster than warmup alone.

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 is sending as your domain, what fails, and the exact record to change. Free SPF and DMARC generators create correct records in minutes, and domain and IP reputation is tracked continuously with alerts when a signal drops.

How Mailwarm does itMailwarm shows spam signals and placement. It doesn't list DMARC or blacklist monitoring.
04

Measuring results

Warmy's placement tests run outside the warmup network and break results down by provider, showing inbox, Promotions, and spam. Scheduled auto-tests keep a fresh baseline.

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 tests with live inbox vs spam reporting.
