How it works

From a name
to a reply.

1Find the lead

You find the lead on LinkedIn.

A profile, a people search, a company's people tab. Tick the ones you want, up to 100 at a time.

4Email + sequence

It finds the email and writes like you.

Email found in under a minute. The first email is drafted from your pitch, your voice and the prospect's own website. Four follow-ups, weekends skipped.

Dashboard timeline of a prospect: email found, first email sent, follow-up scheduled
5Dashboard

Every step, in one place.

Who got an email, who opened, who replied. The sequence stops the moment someone answers or bounces. 50 emails a day, never more.

Good to know

Questions, answered.

Does it really send from my own inbox? +

Yes. HumanInbox connects to your Gmail and sends every message from your own address, in the same thread. DKIM and SPF aligned, no "via" tag, no tracking domain. Recipients can't tell it was assisted.

Will it email anyone without me? +

Never. An agent only writes to the people you assigned it to. You set how many follow-ups it can send, and you can pause any agent at any time.

Is this a cold-email blaster? +

No. There are no lists and no blasts. You assign one agent to one contact you chose yourself, and it runs one conversation, in your voice, until it gets an answer.

What happens when someone replies? +

The agent stops instantly. It watches the thread and cancels anything still scheduled the moment an answer lands. No double-texting, ever.

What can it read? +

Only what it needs to run the threads you assigned: the conversation itself and the open signals on the emails it sent. You can disconnect at any time.

Do I need a card to try it? +

Not to look. Install the extension, connect Gmail, and watch your agents line up their first drafts. The card is only asked when you start the 7-day trial, and you can cancel in one click.
