TrulyInbox Review 2026
Last reviewed October 2026 by Théo Pascard
TrulyInbox
AI email warm-up priced by daily warm-up emails, not by connected accounts
Overview
TrulyInbox is an email warm-up tool. It connects to your mailboxes by OAuth (Google and Microsoft) or by SMTP and IMAP. It then sends and receives AI-written warm-up messages with a network of accounts that the vendor describes as real, not bots. You pick a strategy (AI Adaptive, progressive, random or flat), an industry and a topic. The tool then reports a 0 to 100 deliverability score by receiving provider and an outreach readiness indicator. Its distinctive point is the price: plans are sized by daily warm-up emails, and paid plans allow unlimited connected accounts. The vendor states 95%+ average inbox placement and a network of 40,000+ accounts. Both are vendor claims.

Does TrulyInbox charge per mailbox?
No. It charges for warm-up volume. Paid plans allow unlimited connected accounts and share the daily warm-up emails across them, so with more accounts each one gets fewer. The vendor suggests a 2:1 ratio, two warm-up emails for each cold email a mailbox sends. It lists Starter as suited to about 3 inboxes, Growth to 15, Scale to 50 and Scale Plus to 100.
Does TrulyInbox warm-up improve inbox placement?
That is the vendor's promise. It states 95%+ average inbox placement and results in 2 to 3 weeks. These are the vendor's own figures, and no method for measuring them is published on the pages read.
