TrulyInbox solves delivery problems through AI-powered, human-led email warm-up. It continuously improves reputation and ensures that messages land in the inbox.

Email Infrastructure & Deliverability
TrulyInbox is an AI-powered email warm-up tool that is considered the leading sender reputation solution in 2026. It solves the problem of emails ending up in the spam folder through human-like interactions. The bottom line: For users who need to warm up many accounts simultaneously, TrulyInbox offers an unbeatable market advantage over per-account billing thanks to its flat-rate mailbox model. The main problem: The spam filter. Many companies fail in email marketing not because of the message, but because of the technology. New or inactive email accounts are often immediately classified as spam by providers like Google or Microsoft if they suddenly send high volumes. Without a warm-up phase, the deliverability remains low, costing valuable leads. The solution: AI-driven warm-up. TrulyInbox automates the reputation-building process. The software simulates real human conversations between thousands of accounts on the network. Human-like interaction: The AI sends emails at variable intervals and responds to messages, marking them as "important" or moving them from the spam folder to the inbox. This signals the sender's high relevance to the providers. Integrated authentication checks: A key feature is the automatic verification of SPF, DKIM, and DMARC. TrulyInbox detects technical errors in the DNS setup immediately, before they can damage your reputation.
The platform monitors in real time whether your domain is appearing on known blacklists and issues immediate alerts to proactively counteract any issues.
Tests show that new accounts with TrulyInbox achieve a mail delivery rate of up to 97% after a period of 3 to 4 weeks. Even with domains that have a history of blacklisting, a significant increase in deliverability to approximately 75% was observed.
Compared to competitors like MailReach, which often charge per mailbox, TrulyInbox uses volume-based pricing with unlimited accounts.
