Deliverability Is a Competitive Advantage
Two companies can send identical emails — one reaches the inbox, the other lands in spam. The difference is deliverability: authentication, reputation, content quality, and engagement signals.
SprintMailer's deliverability platform gives you visibility into every factor affecting inbox placement, with actionable recommendations to improve your rates over time.
Real-Time Inbox Placement Testing
Stop guessing where your emails land. SprintMailer's seed-list testing sends your campaign to real inboxes across major ISPs and reports placement within minutes:
Run tests before every major campaign or set up automated weekly monitoring.
Gmail
inbox, promotions, spam, or missing
Outlook/Hotmail
inbox, junk, or missing
Yahoo/AOL
inbox, bulk, or missing
Apple Mail
inbox or junk
Authentication & Compliance Monitoring
Broken SPF, DKIM, or DMARC records can cause immediate deliverability drops. SprintMailer continuously validates your authentication setup and alerts you to:
Missing or changed DNS records
DMARC policy violations
Certificate expiration
Alignment failures between From domain and DKIM domain
Blacklist & Reputation Protection
We monitor 100+ blacklists including Spamhaus, Barracuda, SORBS, and SpamCop. If your IP or domain gets listed, you receive an instant alert with delisting instructions.
Combined with Google Postmaster Tools and Microsoft SNDS data, you get a complete picture of how ISPs view your sending reputation.
