Advanced Deliverability
Review sender setup, authentication, list hygiene, and campaign signals before you send. BuffSend helps surface risks; mailbox providers still decide placement.
Deliverability checks and controls
Use sender checks, authentication guidance, and campaign monitoring to review deliverability risk before and after a send.
Campaign and sender signals
Review recorded bounces, complaints where available, and engagement signals for campaigns and connected senders. Use the trend to decide what needs attention.
- • Bounce and failure signals
- • Complaint signals where available
- • Engagement reporting
- • Campaign-level review
Authentication & DNS checks
Run checks for SPF, DKIM, and DMARC records and follow setup guidance. BuffSend reports what it can read; DNS changes remain with you.
- • SPF record checks
- • DKIM record checks
- • DMARC policy review
- • DNS guidance
Sender health review
Bring authentication status, bounce context, complaint signals, and sending history together for a practical review of sender health.
- • Authentication status
- • Bounce and complaint context
- • Sending-history review
- • Investigation prompts
List and suppression checks
Review verification results, duplicate records, unsubscribes, and bounce suppressions before you send. Keep removal decisions under your control.
- • Email verification
- • Duplicate review
- • Suppression checks
- • Engagement-based review
Pre-send content and rendering checks
Use content analyzers, subject checks, preview tools, and rendering review to catch issues before a campaign goes out. These checks are not an ISP-wide placement test.
- • Subject and copy checks
- • Spam-language review
- • Preview and rendering review
- • Pre-send checklist
Responsible-sending controls
Use unsubscribe handling, consent and audience review, and sending guidance as part of your process. BuffSend does not certify legal compliance.
- • Unsubscribe management
- • Audience review
- • Content guidance
- • User-owned compliance decisions
Why deliverability checks matter
Poor deliverability can reduce the number of useful conversations a campaign creates. BuffSend helps you review sender setup, list quality, and campaign signals; inbox placement still depends on recipient behavior and mailbox-provider decisions.
Make better send decisions
Use observed signals to decide whether to send, pause, verify, or investigate. Results still depend on your audience and mailbox providers.
Protect sender health
Authentication, list hygiene, and complaint review can help you spot risks earlier; no tool can guarantee reputation outcomes.
Create a repeatable review
Bring pre-send checks and post-send review into one workflow instead of relying on a single score.
What this workflow helps you check
- • Authentication records and DNS results
- • Verification, suppression, and list signals
- • Bounce, complaint, and engagement trends
- • Copy, subject, and rendering issues
No tool guarantees inbox placement. Use these signals with your own sending and audience context.
