Hello Inbox – AI Email Deliverability Stack for Serious Senders

Description

Hello Inbox is an AI deliverability stack built to get marketing and cold emails into the inbox instead of the spam folder. It combines an AI deliverability expert with nine practical tools for testing, monitoring and fixing your sending setup, so you can find and solve problems before they hurt open rates.

Hello Inbox was founded by CEO Hans Desjarlais, a top-rated deliverability specialist on Upwork, and is based in Canada. The company says more than 7,000 businesses and marketers have used it and that it has helped recover more than 3M in revenue. It reached number three on Product Hunt on 14 September 2026 with 283 upvotes. Users can also join a Discord community or book an intro call for hands-on help with deliverability problems.

Who Hello Inbox Is For

Hello Inbox suits anyone whose revenue depends on emails actually being seen:

• Email marketers who want to protect open and click-through rates on campaigns.
• Cold outreach and sales teams that need healthy domains and warmed-up inboxes.
• E-commerce brands that rely on newsletters and automated flows for sales.
• Agencies managing deliverability for several clients, with white-label options on Enterprise.

Core Capabilities

AI Deliverability Expert

The AI expert uses retrieval-augmented generation and persistent memory, so it remembers your setup. You can chat with it about your test results and get specific advice rather than generic tips.

Testing Before You Send

The Deliverability Test checks SPF, DKIM and DMARC records, blacklists and links, while the Inbox Placement Test shows whether messages land in the inbox or spam at Gmail, Outlook and Yahoo.

Content and List Hygiene

A Spam Word Checker flags risky phrases and can rewrite them with AI, an Image Alt Text Generator improves accessibility, and Email List Verification removes bad addresses before they damage your sender reputation.

Ongoing Monitoring

DMARC Monitoring, Sender Profiles connected to Google Postmaster Tools and Deliverability Monitoring alerts keep watch over your domains. A Warmup Toolkit supports services such as Instantly, Lemwarm and InboxAlly.
