email warmup tool to avoid spam folder

Mailwarm is an email warmup and deliverability platform designed to help businesses consistently reach the inbox instead of spam folder.

Email deliverability is a critical factor in modern marketing and outbound sales. New domains, new inboxes, and sudden increases in sending volume often trigger spam filters due to low sender reputation. Mailwarm addresses this challenge by gradually building trust with mailbox providers through automated, multi-provider engagement across Gmail, Outlook, Microsoft 365, Yahoo...

The platform strengthens sender reputation by generating natural email interactions, monitoring spam score performance, preventing harmful bounce signals, and providing detailed deliverability analytics. This structured email warmup process helps teams scale email outreach.

Founded in 2020, Mailwarm is backed by Y Combinator and Station F. The platform is used globally by startups, SaaS companies, agencies, recruiters, and sales teams that rely on email as a revenue channel.
