DNS records are missing or overlap
Incorrect SPF, DKIM, or DMARC records make the sending source difficult to verify.

Deliverability isn't luck — it's technical precision.
Misconfigured DNS records or sudden volume spikes trigger Gmail and Yahoo spam algorithms instantly.
Volume grows too quickly
A new domain or IP sends a sudden spike before establishing a stable history.
Bounce and complaint signals never return
Invalid addresses and objecting recipients continue to appear in later campaigns.
The team only looks at open rate
Early signals from configuration, queues, and providers remain invisible.
Four core capabilities
Build sender reputation through a repeatable control loop.
No button can guarantee inbox placement. A disciplined process reduces preventable errors and surfaces negative signals earlier.
DNS HEALTH
Verify SPF, DKIM, and DMARC
See each record status, the value to add, and the next verification step.
WARMUP
Increase volume through a planned schedule
Set a ramp for a new domain or IP and adjust it using actual provider feedback.
FEEDBACK
Bring bounce and complaint signals together
Use delivery feedback to remove invalid addresses and suppress objecting recipients.
MONITORING
Compare by domain and provider
Separate configuration failures from list-quality or campaign-content issues.
Operating model comparison
Move from post-incident recovery to pre-send control.
The difference lies in when a problem is found and who is responsible for resolving it.
Decision pointPrevious approachWith eMailBase
DNS configuration
Run isolated checks across several tools.
Use one checklist for SPF, DKIM, and DMARC.
Warmup
Increase volume on a fixed calendar.
Adjust the schedule using delivery feedback.
Bounce handling
Review only the total after a campaign.
Classify failures and suppress invalid addresses before the next send.
Complaints
Feedback stays inside each provider.
Centralize signals and apply suppression rules.
Send decision
Rely mainly on instinct.
Use configuration, history, and queue status together.
Inside the product
Monitor domains where sending routes are configured.
The Sending Domains screen shows which domains have been added and their current verification state. Performance metrics should be interpreted alongside provider and campaign data.

Metrics to monitor
Measure progress through operational signals.
Domains with completed SPF, DKIM, and an appropriate DMARC policy.
Addresses that do not exist or are permanently rejected.
Recipient objections tracked by campaign and list source.
Frequently asked questions
Who owns deliverability work?
Marketing, engineering, and data owners each have a defined responsibility.
No. Authentication is foundational, but content, frequency, list quality, and recipient engagement still affect placement.
Consider warmup for a new domain or IP and after significant volume changes. Use actual delivery feedback to shape the schedule.
Place hard-bounced addresses on a suppression list to prevent repeated failures and protect sender reputation.
Check before you scale
Put domain health into the operating checklist.
Connect a test domain and review authentication records before the next campaign.
