Send a test email to receive analysis of authentication, content, and reputation, along with AI-generated recommendations for addressing detected issues.
HelloInbox
HelloInbox is an email deliverability platform that helps marketers test inbox placement, authentication, content, list quality, and sender reputation. It combines AI guidance with monitoring and corrective workflows for campaign review, domain launches, and ongoing sender hygiene.
Email deliverability testing and monitoring
HelloInbox is an email deliverability platform for marketers and other senders who want to improve inbox placement. It combines an AI deliverability assistant with testing, authentication monitoring, list verification, content checks, inbox placement tests, and ongoing alerts.
The product’s stated workflow is to add sending domains and import relevant data, run diagnostic tests, then apply recommended fixes and monitor performance. Its AI can use a sender profile, past conversations, email platform data, and individual test results to provide situation-specific guidance rather than only general deliverability advice.
Deliverability tools and workflows
DMARC monitoring
Collect DMARC reports, track compliance, and receive guidance for strengthening the policy while avoiding disruption to legitimate mail.
Email list verification
Check individual addresses or full lists for invalid and temporary email addresses before they affect sender reputation.
Content and accessibility checks
Identify spam-triggering words in subject lines and body copy, with AI-assisted rewriting for flagged content. The toolkit also generates descriptive alt text for email images.
Inbox placement testing
Run placement tests across Gmail, Outlook, Yahoo, and other major providers to see whether messages reach the inbox, spam folder, or promotions tab.
Sender profiles and monitoring
Create sender profiles, connect Google Postmaster Tools, and enable alerts for events such as blacklisted IPs, spam-rate spikes, reputation drops, and new test results.
Practical use cases
Pre-send campaign review
Before sending a campaign, use the deliverability and content checks to review authentication, reputation signals, spam-triggering copy, and list quality so problems can be addressed before launch.
Investigating inbox problems
When a domain is producing weak open rates or unexpected spam placement, combine inbox placement results, reputation analysis, and monitoring alerts to identify where delivery is failing.
Domain launch or reputation recovery
For a new sending domain or a domain with a damaged reputation, use the warmup toolkit and the assistant’s guidance to plan the recovery process and track warning signals.
Ongoing sender hygiene
For ongoing newsletter or automated email programs, verify lists periodically, monitor DMARC and deliverability signals, and use alerts to catch changes before they affect more campaigns.
