Estimate how many subscribers your email campaign can actually reach after bounces, suppressions, and delivery loss. Use it to judge list quality, sender reputation, and campaign scale before sending.
The result turns raw marketing inputs into an actionable performance metric. Use the supporting stats, status, and health score to decide whether to scale, optimize, or reduce waste.
Benchmarks are directional. Always compare results with your own campaign history, margins, tracking setup, and attribution rules.
For a 25,000-contact list with 2% bounce, 3% suppression, and 99% delivery, estimated reach is about 23,523 reachable subscribers.
Multiply your list size by the remaining percentage after bounce rate, suppression rate, and delivery rate. This calculator gives that realistic reachable audience estimate.
Every bounced address reduces the number of people who can receive the campaign and may also damage sender reputation if the bounce rate stays high.
A strong campaign usually has delivery near 98% or higher, but the correct benchmark depends on list quality, sender reputation, and email platform filtering.
Reach is lower because some contacts bounce, unsubscribe, get suppressed, or fail delivery before the campaign can appear in the inbox.
Improve reach by validating addresses, removing inactive contacts, reducing bounces, segmenting risky subscribers, and improving sender reputation.
| Metric | Meaning |
