Comparison
Default Mailgun settings vs SleekView
Default Mailgun settings
- Settings page is per-site — no multisite roll-up
- Region (US/EU) is a hidden dropdown easy to miss
- Tracking-clicks dropdown has 3 values — no audit grid
- Override-from setting drift causes silent deliverability hits
- No quick way to find sites still on legacy SMTP mode
SleekView
- Multisite roll-up of every blog's Mailgun config
- Surface region, mode, and tracking flags as columns
- Catch sites with no region (defaults to US — bad for EU GDPR)
- Inline-edit override-from across many sites
- Filter for SMTP-mode sites that should move to HTTP API

SMTP mode is the legacy fallback. Filter for sites still using it and migrate them to the HTTP API for better deliverability.
Override-from review
Custom "From" addresses outside your sending domain hurt SPF/DKIM. Audit them in one column.

Questions

In wp_options under the mailgun key. The plugin also respects MAILGUN_* constants in wp-config.php. SleekView shows both, with constants flagged as read-only.
Yes. The useAPI flag inside the option array determines API vs SMTP. SleekView surfaces it as a column you can sort and filter.
Yes — the plugin reads the option on each send. Edit in SleekView and the next email uses the new config. Constants in wp-config.php still win.
List subscriptions live in Mailgun's cloud — the plugin only fronts the form. SleekView covers the WP-side shortcode placement and the API config.
