HumanInboxとは
Email finder + AI agent: finds the email of any professional profile, writes the cold email, sends from your Gmail, follows up. You find the lead. Our AI agent does the rest.
HumanInbox turns any professional social media page into a one-click outreach machine. Open a profile, a people search, a company's people tab, or the reactions on a post. Tick the people you want. Click once. From there, everything is done for you:
1. FINDS THE EMAIL. The agent looks up the professional email address of each person across several data sources and verifies it before anything goes out. Usually under a minute. No address found, no credit spent.
2. WRITES IN YOUR VOICE. It reads the prospect's company website, then drafts a first email from your pitch, your offer and your own writing style (analyzed from your sent emails, if you want). Five styles: Sharp & Direct, Quick Note, Open Question, Confident Pitch, Offer-First. One email per person, no template with placeholders.
3. SENDS FROM YOUR GMAIL. Every email leaves from your own Gmail account, in your name, as a normal email. No sending infrastructure, no separate tool the reply has to route through.
4. FOLLOWS UP, THEN STOPS. Four follow-up emails over 18 days, weekends skipped, each one short and in the same thread. The sequence stops the moment the person replies or the email bounces. Out-of-office auto-replies are ignored.

5. SHOWS YOU EVERY STEP. Your dashboard lists each prospect with what happened: added, email found, first email sent, follow-up scheduled, opened, replied. Nothing hidden.
WHERE THE BUTTON LIVES
- A HumanInbox tab on the right of every page of the professional social media platform. Click it to see the people detected on the page.
- Inside the "Reactions" window of any post: a HumanInbox button next to the close cross lists everyone who liked the post. Scroll to load more, select all, one click.
- Paste any professional profile URL by hand if you already have it.
- Up to 100 people per click.
BEFORE YOU PUT IT ON ANYONE Ask the agent to write a sample sequence to a made-up prospect, or to a company whose website you paste. Read the five emails. Not right? Tell the coach what to change ("too salesy", "shorter", "lead with a question") and it rewrites the agent's brief, then the first email, in seconds. What you converge on is exactly what the agent will use.
BUILT TO KEEP YOUR INBOX SAFE
- Hard cap of 50 emails per day per inbox. Emails over the cap wait, they are never dropped.
- Sent from your Gmail, so replies land in your inbox like any other conversation.
- No approval queue, no CSV, no copy-paste.
- Nothing is injected into the platform's interface: the extension only reads the page and shows its own panel. It never posts, likes, connects or messages on your behalf.
HOW IT COMPARES Most email finder extensions stop at the address; HumanInbox puts it straight into a personalised cold email sequence, sent from your Gmail. Mail merge tools send one template to many people; HumanInbox writes one email per person from that person's context. Sequencers need you to feed them lists and copy; here you tick people where you already find them, and an AI agent handles the prospecting from the first email to the last follow-up.
WHO IT IS FOR Founders, solo sellers and small teams who find their own leads on professional social media and want the follow-up done properly, without a sales stack.
PRICING 7-day free trial with 10 prospects included. Plans from 29 EUR per month for 100 prospects. Each prospect includes the email lookup and the full five-email sequence.
PRIVACY The extension reads the page you are looking at (names, headlines, profile URLs, photos) only when you open the panel or click the button, and sends to HumanInbox only the people you assign. Gmail access is used to send your emails and detect replies. Full policy: https://gethumaninbox.com/privacy
