The record

What it does: InboxWarm.ai automatically warms Gmail, Outlook, and SMTP inboxes to build sender reputation, improve inbox placement, and reduce spam placement.
AI engagement: The service sends, opens, and replies to warmup emails using LLM-generated contextual replies and human-like sending patterns.
Seed network: InboxWarm says its warmup uses a private network of real seed inboxes rather than bots or recycled accounts.
Spam recovery: Its spam recovery engine marks warmup messages as not spam and moves them to the primary inbox when they land in spam.
Integrations: Supported sending setups include Gmail, Outlook, SendGrid, Amazon SES, Mailgun, Yahoo, and custom SMTP/IMAP.
Authentication monitoring: Plans include SPF, DKIM, and DMARC domain-health monitoring plus real-time inbox-placement tracking.
Security: InboxWarm says credentials are encrypted end-to-end, never stored in plain text, and can be deleted with account data from the dashboard.
API: The public REST API provides 30 endpoints for email accounts, warmup, deliverability, reports, spam tests, and system functions, included in every plan.
API limit: The default API rate limit is 20 requests per minute per API key.
Trial terms: The 10-day trial provides full warmup access for up to one email account without a credit card.
Billing flexibility: Users can add or remove inboxes from the dashboard, with billing adjusted proportionally on the next invoice.
Support: InboxWarm says its support team is available 24/7 by email at [email protected].
Target customers: The company describes its audience as ranging from startups to enterprises, including agencies, SaaS teams, and cold-email teams.
Warmup timeline: InboxWarm says a full warmup typically takes about four to six weeks, with measurable improvement often appearing within two to three weeks.
