Newsletter – Sendgrid

This is EXACTLY the same product as distributed by the developer. Sales Page

Core Specifications

• Developer: The Newsletter Team (official add-on).

• Integration Method: Twilio SendGrid Web API v3. This is more reliable than standard SMTP because it is less likely to be blocked by firewalls and handles high volumes more efficiently.

• WordPress Requirements: Typically requires WordPress 6.1+ and PHP 7.0+ (matching the core plugin’s requirements).

• SendGrid Requirements: A SendGrid account (Free or Paid) and a Full Access API Key.

Key Features

• Improved Deliverability: Uses SendGrid’s reputation-managed servers to ensure emails land in the inbox rather than spam.

• Webhook Support: Automatically processes Bounces and Complaints (Spam reports). When a subscriber’s email bounces, SendGrid notifies the plugin via a webhook, and the plugin automatically updates that subscriber’s status to “Bounced.”

• Click & Open Tracking: While the core Newsletter plugin has its own tracking, this add-on can sync with SendGrid’s native tracking for more granular data.

• Batch Sending: Respects the delivery speed limits set in the main Newsletter plugin configuration (e.g., 5,000 emails per hour) to ensure you stay within SendGrid’s plan limits.

• Security: Uses API key authentication, removing the need to store your main SendGrid password within WordPress.

Configuration Requirements

To set this up correctly, you will need to provide:

• API Key: Generated from your SendGrid Dashboard (Settings > API Keys).

• Sender Authentication: You must complete Domain Authentication (SPF/DKIM) within SendGrid for the “From” address to be verified; otherwise, emails may be rejected.

• Newsletter Settings: In the WordPress dashboard, you must navigate to Newsletter > Delivery and select SendGrid as your delivery engine.
