Dive deeper into how SprintMailer helps you achieve better results.

01

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.

02

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

03

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

04

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.
