Email Deliverability Check
Email Deliverability Check helps teams assess whether contact lists are ready for sending before campaigns, onboarding sequences, or transactional notifications. Deliverability issues often hide behind apparently valid addresses, then surface as bounce spikes, complaint risk, and distorted engagement reporting after launch. This page focuses on practical pre-send checks: syntax validation, domain and MX signal review, and quick filtering of obviously risky entries before they reach your ESP or CRM workflow. It is useful for marketing operations, lifecycle teams, outbound sales, and product communications where list quality directly affects performance and sender reputation. By using a repeatable deliverability-check routine, teams can clean segments faster, improve handoffs between data and campaign owners, and reduce last-minute firefighting on send day. The result is more predictable sending outcomes and cleaner performance data for optimization decisions.
What Email Deliverability Check Does
Run an email deliverability check for syntax, domain, and MX signals before campaigns to reduce bounces and list risk.
Common Use Cases
- Pre-check campaign recipient lists before newsletter or lifecycle sends
- Validate imported contacts from forms, events, or partner data sources
- Reduce hard bounces in outbound sales and trial nurture workflows
- Screen risky addresses before syncing segments into an ESP
- Improve sender-reputation protection with recurring list hygiene checks
How It Works
- Upload or paste the recipient list you plan to send
- Run syntax, domain, and MX signal checks on all entries
- Separate invalid and risky contacts from valid recipients
- Export the cleaned segment and proceed with campaign scheduling
Examples
Campaign preflight validation
Input: 1,500-recipient segment prepared for monthly product update
Output: Invalid syntax and no-MX entries removed before send approval
Imported lead cleanup
Input: CSV list collected from webinar registrations
Output: Filtered list grouped into valid, risky, and invalid buckets
FAQ
What is included in an email deliverability check before sending?
A practical pre-send check covers address syntax, domain validity, and MX record presence, then flags obvious risk cases for removal or manual review.
Can deliverability checks reduce bounce rates immediately?
They usually reduce avoidable hard bounces by removing clearly invalid contacts, but overall inbox results still depend on sender reputation and content quality.
How often should high-volume teams run deliverability checks?
Run checks before each major campaign and on a recurring hygiene cadence, such as monthly, to prevent stale or degraded data from accumulating.
