Summary
InboxWarm.ai automatically warms Gmail, Outlook, and SMTP inboxes to build sender reputation, improve inbox placement, and reduce spam placement. It sends, opens, and replies to warmup messages with LLM-generated contextual replies and human-like sending patterns. The company describes its seed network as a private set of real inboxes. Its spam recovery engine marks warmup messages as not spam and moves them to the primary inbox when they reach spam. Supported setups include Gmail, Outlook, SendGrid, Amazon SES, Mailgun, Yahoo, and custom SMTP/IMAP. Plans include SPF, DKIM, and DMARC monitoring plus real-time inbox-placement tracking. Every plan includes a public REST API with 30 endpoints; its default rate limit is 20 requests per minute per API key. The 10-day trial gives full warmup access for one email account without a credit card. Listed monthly plans range from 15.00 USD per month for one mailbox to 5.00 USD per month for 51–100 mailboxes, with up to 100 warmup emails per inbox per day. InboxWarm says a full warmup typically takes about four to six weeks.
