In their own words
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. Product availability, access, and plans vary by product. Listed options include Inbox Insights Monthly at $79 a month for 100 tests and Inbox Insights Yearly at $799 a year for 100 tests per month. Folderly mailbox plans list a minimum commitment and per-mailbox monthly amounts, billed yearly.
Warmerly
Warmerly automates email warmup and checks deliverability for connected mailboxes. Its warmup feature sends threaded conversations with quoted replies and natural delays, and can recover warmup messages that end up in spam. InboxPulse checks SPF, DKIM, DMARC, MX and TLS daily. Google Workspace and Microsoft 365 connect through OAuth; other providers can connect over IMAP and SMTP, including Zoho and Namecheap Private Email. The service also lists LinkedIn warmup and outreach, plus WhatsApp messaging; LinkedIn costs $50/month per account separately. Plans include a free option with 100 campaign emails per month, and paid plans from $19/mo with a 7-day trial. Paid plans state that email sending is unlimited and unmetered. Warmerly runs on Android and the web, and offers an API. The operator says mailbox credentials and OAuth refresh tokens are encrypted at rest with AES-256-GCM, requests use TLS 1.2 or higher, and hosting and backups are in the European Union. The site names agencies, sales teams, telecom companies, lead-generation businesses, founders, SDRs and recruiters as users.
