# Mailgun loses 7 domains in a single day with zero replacements arriving

On August 16, every email provider move recorded against Mailgun ran one direction only.

Seven domains left Mailgun on August 16 and not one came in to replace them, according to DRM3's DomainDrift Trends instrument, which recorded a net of negative seven for the provider that day.[^1]

The zero-adoption figure is what stands out. A net loss can mask churn in both directions. Here it does not - the DomainDrift scan logged no incoming moves at all, leaving the day's shift entirely one-sided.

Mailgun held a 2.2 percent share of the scanned corpus as of that date. Whether August 16 was an isolated day or part of a longer drift is a question the available single-day reading cannot settle - a multi-day trend line for Mailgun would answer it.

## What this stands on

1. Mailgun net -7 domains in email on 2026-08-16 across the scanned corpus. 0 domains adopted it and 7 left it that day. It holds 2.2 percent of the scanned corpus. (DomainDrift, DomainDrift trends, claim on record)
