What TrulyInbox is

TrulyInbox is an email warmer tool in the B2B go-to-market stack. In the vendor's own words: “Boost Your EmailDeliverability.” Put plainly, a tool in this category builds and holds a sending reputation so campaigns reach the inbox.

Where it sits in an outbound stack

Most outbound stacks are four layers: the data that decides who you talk to, the channel that carries the message, the writing that earns a reply, and the system of record that remembers what happened. TrulyInbox sits in the email warmer layer. Tools beside it are worth comparing on coverage and price; tools in the other layers are worth wiring to it rather than replacing it with.

Using TrulyInbox with M for Mercury

TrulyInbox sits on the email side of the stack. Mercury sits on the LinkedIn side and does not try to be your sending platform — Lead Finder returns a verified work email next to every LinkedIn profile and pushes it straight into Smartlead, Instantly, PlusVibe or EmailBison, so TrulyInbox keeps doing what it is good at while the connection request and the LinkedIn follow-up run in Mercury. One person, both channels, without the two lists drifting apart.
