Mailwarm

Mailwarm : Email Warmup Service & Email Deliverability Software Mailwarm is a cloud-based email warmup and email deliverability platform designed to help businesses improve inbox placement and avoid the spam folder. Founded in 2020, Mailwarm helps startups, sales teams, recruiters, marketing agencies, SaaS companies, and outbound teams protect their sender reputation when sending cold emails or launching new domains. Unlike simple automation tools, Mailwarm focuses on long-term sender reputation building through structured engagement signals across major email providers including Gmail, Outlook, Microsoft 365, and Yahoo.

What is Email Warmup? Email warmup is the process of gradually increasing email sending activity to build trust with mailbox providers. Without proper warmup, new domains and inboxes often trigger spam filters due to:

• Sudden sending volume
• Low engagement rates
• High bounce rates
• Poor sender history Mailwarm automates this process by generating realistic email interactions between real inboxes, helping emails reach the inbox instead of spam.

How Mailwarm Differs from Other Email Warmup Tools?

• Multi-provider engagement instead of single-network warmup
• Structured spam score tracking
• Simple and focused functionality
• High quality, relevant engagement
• Built-in bounce prevention systems
• Stable automation designed for scale
• Designed for both startups and agencies Mailwarm was created after its founders experienced repeated spam placement while running outbound campaigns. The internal solution developed to solve that problem later became a full SaaS product used globally.
