Warmy.io is a cloud-based SaaS solution for email deliverability and email warmup services.

This AI-powered email warmup tool provides a full suite of tools to help businesses and marketers improve their email sender reputation, ensuring emails land in the inbox and not the spam folder.

Hereโ€™s how Warmy works:

The tool connects to your mailbox and utilizes an artificial intelligence engine called "Adeline" to warm up your mailbox at an optimal pace. Adeline analyzes hundreds of parameters daily, interacts with real people on your behalf, and ensures that your emails reach the inbox consistently.

Warmy gradually improves sender reputation by automatically opening, marking as important, and removing sent messages from the spam folder, sending signals to mailbox providers that you are to be trusted.

Warmy provides full progress monitoring, offering a clear and transparent process so users can stay informed and in control.

Warmy is compatible with major email providers and offers integration with popular apps and tools, allowing users to streamline their workflows and easily integrate Warmy into their existing cold outreach process.

Warmy also offers a full suite of free tools designed to optimize every step of the deliverability process. These include a free Email Template Checker which scans your content for anything that might set off spam filters, a free Email Deliverability Test to know where your emails are landing, a Cold Email Sequencer, and even free Record Generators for SPF and DMARC.

Overall, Warmy provides a user-friendly and automation-driven solution to optimize email deliverability and enhance email marketing campaigns.
