🆕 What’s New in 3.0.0

This release is built around one central goal: email deliverability. You can now verify your entire subscriber list, filter sends by verification status, and track how verified vs. unverified emails actually perform — all without leaving SEO Panel.

🛡️ Email Verification Center

The biggest new feature in 3.0.0 is the Email Verification Center — a dedicated tool for verifying subscriber email addresses via the Elastic Email API. Run verifications on any email list, control the batch size, and view live output as results come in.

Each email is classified into one of five verification states:

✅ Valid — deliverable address
❌ Invalid — non-existent or rejected address
⚠️ Risky — deliverable but likely to cause issues
📬 CatchAll — domain accepts all emails regardless of the mailbox
❓ Unknown — could not be determined

Results are stored per-subscriber with a full audit trail, and all list views update instantly to reflect the new verification data.

✅ Mark Engaged Subscribers as Valid

Don’t want to use the API for every subscriber? No problem. A one-click “Mark Engaged as Valid” action automatically sets all subscribers who have opened or clicked any newsletter to Valid — using real engagement data as a proxy for deliverability. This is a fast, practical way to clean your list without consuming API quota.

📊 Verification Performance Reports

The Report Summary now breaks down delivery, open, and click rates by verification status. You can see at a glance which email types (Valid, Risky, CatchAll, etc.) are actually engaging — making it easy to decide which segments to include in future sends.

🔍 Verification Filters Everywhere

Verification data is now wired into every relevant area of the plugin:

📋 Email Manager — filter subscribers by verification result
📰 Newsletter Reports — filter report data by verification status + search by email
📤 Newsletter Sending — set a per-newsletter Verification Filter so only the email types you trust (e.g. Valid + CatchAll) are included in the send

📋 Email List Manager — Verification Counts & Stat Badges

The Email List Manager has been significantly enhanced. Each list now shows:

Clickable verification status counts — Valid, Invalid, Risky, CatchAll, Unknown, Not Verified — as color-coded badges that filter directly into the email list
Redesigned Total, Subscribed, Unsubscribed, and Inactive stats as distinct colored pill badges (blue, green, red, amber) — all clickable to filter the list view

🌐 Subscribe Form Improvements

⚡ Quick Generate Subscribe Code shortcut button added to Email List Manager
🔓 Fixed public access — subscribe forms now work correctly for logged-out visitors
🌍 Multi-language support expanded to 46 languages for subscribe/unsubscribe flows
