This process involves interacting with real people on your behalf to build a positive sender reputation with mailbox providers. This process ensures that your future email campaigns land in the inbox.
Key features of Warmy
Comprehensive email deliverability test (free)
Warmy’s free email deliverability test provides a detailed deliverability score critical for evaluating email reputation.
It can check if your emails are landing on its intended recipient and shows the percentage of emails that ends in spam, promotions, inbox, and unreceived across major email providers.
It is also capable of revealing if your domain or IP is listed anywhere on any blacklists.
Advanced AI warmup with customizable Warmup Preferences
Warmy’s AI-powered email warmup simulates real human interactions. Emails are opened, read, scrolled through, clicked on, and replied to. This helps build and maintain a positive sender reputation, ensuring your emails are less likely to be marked as spam.
The Warmup Preferences feature also gives full control to senders when it comes to how the warmup efforts can be distributed per provider.
Advanced seed lists
Warmy’s Advanced Seed Lists uses real email addresses that actively interact with your emails. For example, your email is not just marked as read but it is actually opened and scrolled through. Links are clicked to improve sender reputation. If an email does land in spam, it is manually removed and marked as important to let email service providers (ESPs) know your emails are legitimate.
Using these seed lists, you can test emails in various inboxes (Gmail, Outlook, Yahoo, etc.) to identify potential deliverability issues before implementing email outreach on a larger scale.
SPF and DMARC Record Generator
The SPF (Sender Policy Framework) Record Generator and DMARC (Domain-based Message Authentication, Reporting, and Conformance) Record Generator simplify the process of setting up these crucial email authentication protocols.
