The Problem
Most marketers have inbox problems they don't know about. Here's what's hurting your campaigns right now:
Your carefully crafted emails never reach the inbox. You're losing 30-50% of potential revenue.
Broken authentication records make email providers suspicious. They'll flag you as a potential spammer.
Invalid addresses and unengaged subscribers each hurt your sender reputation.
Once your domain reputation drops, recovering takes weeks or months. Prevention is 10x easier than repair.

Not at all. HelloInbox is designed for marketers, not developers. Our AI assistant explains everything in plain language and gives you step-by-step instructions. If you can send an email, you can use HelloInbox.
Most tools throw a bunch of data at you, and expect you to figure it out. HelloInbox shows you what to do, without the guesswork. You get 9 deliverability tools in one platform plus an AI expert trained by a real deliverability consultant — so you get specific, actionable advice instead of generic reports.
HelloInbox works with any email provider. Whether you send through Gmail, Outlook, Mailchimp, SendGrid, HubSpot, Salesforce, or any other platform — if you can send an email from it, we can test it.
Yes. There are no long-term contracts. You can upgrade, downgrade, or cancel your plan at any time. If you cancel, you keep access until the end of your billing period.
Yes. The Starter plan is free forever — no credit card required. You get 3 deliverability tests, 1 sending domain, 5 AI chat messages every month and access to the Spam Word Checker and Image Alt Text Generator tools. Upgrade only when you need more.
Most users see improvement within days. Run your first deliverability test in under 2 minutes, get AI-powered recommendations immediately, and start fixing issues right away. DNS and authentication changes typically take effect within 24-48 hours.
A sending domain is the domain you send emails from (e.g. yourdomain.com). Each plan includes a set number of sending domains you can monitor. Subdomains (like mail.yourdomain.com or news.yourdomain.com) are included and don't count as additional domains.
A Sender Profile is a complete snapshot of your email setup for a sending domain. It includes your DNS records, authentication status, email types, target audience, Google Postmaster Tools data, and ESP analytics. It gives our AI the context it needs to provide specific, accurate deliverability advice tailored to your domain.
