Deliverability health and validation

HLB gives you tools to measure how your email performs and protect your sender reputation, which can help reminders and offers reach your customers' inboxes.

• Email Health Report (beta): under Dashboard > Email Health Report. It shows a score from 0 to 100, rated High, Good, Low or Bad, based on open, click, bounce and complaint rates and other metrics, with trends and benchmarks. The score updates daily, leaves out the last 24 hours and appears once you have sent at least 500 emails in the last 30 days.
• Email validation: turn it on with the built-in email service. Addresses are checked before sending for correct syntax, a working domain, whether the address exists, risk level and role-based addresses, and rechecked if the last check is over 90 days old. Check a single contact from the envelope icon on their record.
• Risk assessment: sorts an imported list into deliverable, undeliverable, catch-all or unknown, each with a high, medium, low or unknown risk level.
• Bounce classification: under Settings > Email Services, shows why messages bounced and where to fix the cause.
• Postmaster tools: connect Google Postmaster Tools to see domain reputation, spam rate and authentication results. With a dedicated IP subscription, Microsoft SNDS shows blocked status, spam trap hits and complaint rate.

A cleaning company sending seasonal offers can validate its list first and check the health score after each send.

Check campaign spam risks before sending

Run a check from the campaign send screen to review content, sender setup and reputation signals. Use the risk levels and suggested fixes to revise your email, then check it again before sending.
