Email deliverability
Turn sent emails into
seen results.
Your dashboard says delivered. Your revenue says otherwise. That gap is deliverability, the silent killer of email performance. Server acceptance does not tell you whether an email reached the inbox, landed in Promotions, filtered into spam, or was blocked silently.
We measure where emails actually land, then systematically move them into subscribers' primary inboxes with better authentication, cleaner reputation, smarter content, and placement testing that proves it worked.
See what is really happening behind the Delivered metric, and how to fix it.

Why it matters
What poor placement costs you
Every email that misses the inbox is lost opportunity, and the losses compound. A 10% drop in open rate can mean thousands of missed impressions each month and a sender reputation that worsens with every send.
Deliverability is not just an email problem. It is the health of your whole marketing engine.

Email deliverability FAQ
Questions, answered.
The practical details behind how we scope, deliver, and measure this work.
Delivered means the email reached the recipient's mail server, not their inbox. Filtering is driven by authentication, reputation, content, and engagement.
They are your email ID checks: SPF verifies the sender, DKIM confirms content integrity, and DMARC defines how failures are handled.
Authentication changes can show results in 3-5 days. Sustained optimization usually takes 60-90 days depending on volume and domain age.
Usually. Domain warm-up, adjusted cadence, and segmentation restore engagement signals and rebuild mailbox-provider trust over time.
