The Gravity Forms SendGrid Add-On is an official integration designed to replace your web server’s default mail function with SendGrid’s specialized infrastructure. This ensures that form notifications actually hit the inbox instead of being blocked by server filters or marked as spam.
This is EXACTLY the same product as distributed by the developer. Sales Page

Unlike standard SMTP plugins, this add-on uses the SendGrid API. This is faster and more secure than traditional SMTP because it doesn’t require opening mail ports on your server, which are often blocked by shared hosting providers.
You don’t have to send every email through SendGrid. You can toggle SendGrid on or off for specific notifications.
Use Case: Use SendGrid for customer receipts (high priority) but use your standard server for internal admin alerts to save on SendGrid’s monthly email quota.
There are two versions of SendGrid integration:
The Official Add-On: Focuses on Transactional emails (notifications).
The Marketing Add-On (Third-Party): Allows you to map form fields directly to SendGrid Contact Lists for newsletter automation and CRM syncing.
You can apply Gravity Forms’ powerful conditional logic to your SendGrid feeds. For example, only send a notification via SendGrid if a user selects “Urgent Support” or if they are located in a specific region.
To get this running in 2026, you will need:
An Active SendGrid Account: The “Free” tier allows up to 100 emails/day.
API Key: Generated from your SendGrid dashboard with “Full Access” or “Mail Send” permissions.
Domain Authentication: While optional, it is highly recommended to verify your domain in SendGrid to remove the “via sendgrid.net” warning in Gmail/Outlook.
