Deliverability
Built to land. Not to spam.
Deliverability isn't a feature you bolt on at the end. It's the foundation. Stamina gives you full visibility into every mailbox, warmup status, and DNS configuration so your emails reach real inboxes — not junk folders.
Every mailbox. Every status. One view.
See all your connected mailboxes in one place. Track warmup progress, monitor inbox health scores, and know exactly which accounts are ready to send at volume and which ones need more time. Stamina warms up new accounts automatically so you never start cold.
Feature list:
Inbox health score per mailbox updated in real time
Automated warmup with live progress tracking
Warmup email volume scales gradually to build sender reputation
Clear status indicators: warming, ready, paused, or at risk

Send at the right volume. Every time.
Too many emails from one account is how you end up in spam. Stamina puts the guardrails in place. Set daily send limits per mailbox, minimum time delays between emails, and campaign-level caps so volume stays safe across every domain you manage. Customize sender names per mailbox so every email feels personal, not blasted.
Feature list:
Daily sending limits per mailbox and per campaign
Minimum time delay between sends to avoid spam triggers
Campaign-level send caps across multiple accounts
Custom sender name per mailbox for personalized from-lines

If the infrastructure isn't right, nothing else matters.
A great sequence means nothing if your DNS records are misconfigured. Stamina checks every connected domain for SPF, DKIM, and DMARC records and flags anything that could hurt deliverability before you send a single email. Fix issues before they become reputation damage.
Feature list:
Automated SPF, DKIM, and DMARC validation per domain
Clear pass/fail status with specific fix instructions per issue
Domain health checked on connection and monitored ongoing
Catch-all domain detection to protect list quality before sending
