Folderly
Folderly is a suite of AI and email deliverability tools for B2B teams. It combines campaign drafting with checks and monitoring intended to help assess email placement and sender reputation. Inbox Insights reviews inbox placement along with sending IP and domain signals before a campaign; its free plan includes 2 tests per month. Pulse tracks placement over time, and real-time alerts are available for free. Folderly AI turns an offer, audience, and goal into a campaign draft and directs users to relevant checks. Other tools cover DMARC reports, public DNS and IP inspection, email HTML previews, and real-message testing; DMARC is a pilot and Mirror is in beta. Folderly says it connects to email service providers through API and SMTP, supports custom providers, and names Amazon AWS, Sendpulse, Elastic Email, Google Workspace, SendGrid, and Microsoft Outlook.

Warmforge
Warmforge is an email warm-up and deliverability service for Google Workspace and Outlook mailboxes. It uses AI-written messages to imitate mailbox activity and automatically warm accounts, recommending at least two weeks before outreach. Health Checks review DNS and MX records and check blacklist status. Placement tests show delivery rates across email providers; every plan includes one free test each month. Warmforge says it removes warm-up messages that reach spam. Its curated pool uses aged accounts and is dominated by Google Workspace and Microsoft 365 mailboxes. Monitoring covers inbox placement, sender reputation, authentication, and blocklists. Users can explore features for free, but mailbox warming requires purchased slots, with one mailbox per slot. Platforms include web, macOS, Windows, and API access. Forge CLI manages mailboxes, statistics, and placement tests. Pricing starts at $10 a month, with additional testing plans available.
